Help! I was burried in a pile of hardware.

hello and welcome before i start i would thank  you all for the great feedback which i got from   you recently all the tips constructive critics  or simple thing you really made my day more than   once meanwhile the channel crossed the mark of  10 000 subscribers and i'm really happy to see   that so many people found some fun in my content  the amount of comments also increased a lot and i   assure you guys that even if i don't answer each  one i read all of them so thank you very much   as i told in one of my videos some time  ago meanwhile i even got some donations   from the viewers and today i would  like to take a look into this huge box   which i got from a longtime viewer stevor  from slovakia to torch me in excitement   he sends some photos so i already know  about some of the parts in advance and the first box seems to be some kind of pci  express card but inside there is something else it   is a pci usb 2 adapter actually a very useful part  for any system with a pci bus and is very helpful   if you want to transfer data to another pc using  an usb stick or an external hard drive for example the next part is the adaptec pci skyzico  controller a very widely used controller for skazi   devices back in the days works perfectly even  today because the drivers are very easy to find   and another scasi controller obviously from a  compact oem machine it supports white scuzzy   only and it has a 64 bit pci connector which  was usually used in servers back in the days okay what's next here is river  tnt 2 vanta 8 megabyte agp   this is a low cost version of 18 t2 also known  under the name tnt2 m64 it was produced with   the memory interface reduced from 128 bits to 64  bits this card outperformed the older river tnt   while being less costly to produce and still it  was a lot slower than the real tnt2 they were   quite popular in the oem market as most consumers  simply assumed all tnt2 cards were the same   which obviously was not the case but this is a  very good card for testing of earlier agp systems and the next one is obviously another nvidia agp  graphics card the geforce fx 5200 this one was   also widely used in the oem market back then  ati put nvidia under high pressure releasing   their radeon 9500 and 9700 cards they outperformed  nvidia in every test by high margin and already   supported directx 9 out of the box at that time  nvidia had nothing comparable in the hands so they   introduced the infamous fx 5000 row of graphics  cards which weren't competitive to ati at all but   at least they supported directx 9. the fx 5200 was  the slowest of the series but still got quite hot   and as you see someone added a custom fan on  top of the cooler to get the temperature down   this card was made by msi and is in good visual  condition the capacitors don't seem to be blown   so i guess this is also a good card for testing  purpose the next one is some red main board   oh there is a small knot which probably  fell from something off so the main board   seems to be equipped with painting 4 3  gigahertz with hyper threading 848-neo-v steeper was so friendly to include the atx io  shield with the board thank you very much for that so yes the board is an msi 848p neo-v a nice red  board with an agp slot where we could put the   red msi geforce fx 5200 which we saw previously  that would make a nice all red look to the system   the capacitors are all in outstanding visual  condition nothing is blown the main board is   very clean also the cpu cooler looks very clean  as good as new i would even say this board seems   also to support sata and ide a sound and  network on board it could make a good base   for a nice painting for retro build next one  is a win tv pci tv tuner card it's not usable   for watching tv today anymore since the  frequencies were turned on in a while but   this card can still be used for capturing video  signal from home computers like c64 zx spectrum   and others since such cards have not only the  tuner but often also composed and is video input the next one is the m audio audiophile  2496 a semi-professional sound card   which delivers better audio quality compared to  the most of gamers sound cards from that time   i know that this card was used quite a lot by  musicians back then this connector was used   for a harness which contained additional options  for digital analog as well as midi in and output   and here we have an isa super i o controller  with lobby ide serial and parallel interfaces   i'm always glad to have another one of those  here we have one from goal star electronics and   it was extremely widely used on the back there are  also jumper settings printed directly on the pcb   that is very helpful but i think that the quality  check sticker was placed very inconveniently   and i will probably remove it later okay  the next part already looks very intriguing   there is just work okay written on it but  i have currently no idea what this could be okay i guess i know what this is but i never held  something like this in my hands before so i might   be wrong i think this is a standalone card which  could be plugged into a server for its monitoring   as you see this card has an own power plug avga  output a ps2 keyboard and mouse port and an   rj45 network port this card is a computer for  itself it has a dedicated cpu intel i960 which   is capable to run an embedded operation system and  it has an own graphics chip ati 3d range with the   four dedicated memory ics around it i think this  card was plugged into a pci slot of this server   and connected internally to a special  monitoring header on the main board   this way the server could be observed and  controlled even if it was hanging or unpowered   this is very interesting part and i will  have to take some time to learn more about it okay what's next 50 pin skz cable and another one and another skz cable this  time for ultra wide scarsy the next is a pci network card   it's an amd network adapter but the interesting  thing about this one is that it has optical   transceiver usual copper cables are limited in  length because the signal strength decreases every   next meter and some kind of amplifier switch hub  whatever has to be installed to keep up the signal   quality this can be worked around by using optical  network cards like this one which can be connected   over hundreds of meters without any signal  lost and here is another one so should i want   to connect two computers over a longer distance i  would be able to take these nice network adapters the next one is an iso network adapter oops seems  that this one unfortunately didn't survive the   trip that is a shame this is a nice network card  but the ic was ripped off the pcb completely with   all the pads so the repair is unfortunately not  reasonable otherwise this would be a nice card   okay the next one seems to be a cpu umc 486  dx3340 rare i bet it is i never saw one in person umc green cpu u5s super 33 40. a little jump  forward this is what i found on wikipedia about   the cpu the u5s version unfortunately has no fpu  and is obviously comparable to the intel 486 sx   however down here there is something interesting   performance the umc u5 series design was focused  on microcode optimizations an equivalently clocked   intel or amd processor required 40 cycles to  perform an integer division whereas the umc   processor required only 7 allowing the instruction  to complete significantly faster performance is   generally observed to be higher than competing  processors on a clock 4 clock basis the 40mhz u5s   model being comparable to an amd am 486 sx 2 at 66  megahertz with correctly configured motherboards   sounds good to be true isn't it well this cpu  was benchmarked at 33 megahertz on the cpu galaxy   channel a while ago and the results were really  impressive i'm very excited about it and you   will probably see this cpu in the one or another  benchmark on my channel as well also interesting   that due to an error in the microcode microsoft  windows 98 second edition identifies some   processors as an intel pentium mmx which could  cause the operating system and software running   with it to crash or exhibit undefined behavior  i'm really curious to find out more about it   and the next package is i see 287 steeper told me  about this one and here you go an intel i287xl the   interesting fact about this one is that this ic is  actually a 387 fpu but intel reproduced them as a   drop-in replacement for the original 287 fpus for  the older systems the real 287 core processors did   usually run at lower clock than the cpu but since  this one is a newer but tecported technology it   actually is able to run at the same clock as the  main cpu and deliver the best fpu performance you   can get on a 286 a very rare and expensive model  and i'm super happy to have it in my collection   now i will use it in my 286 machine which can  run the fpu with the same clock as the cpu   so the next package has cm72 on it and yes here  we have a bunch of 72 pin ram modules indeed   i actually have a lot of ram but i'm still  glad about this package since as far as i   can see most of these modules are fpm and  they are harder to find than the edo modules   and for the 486 builds you need fpm only memory  very very nice the next package has a vga   wdc written on it this is probably  a western digital iso graphics card   and it is i absolutely love them in my opinion  this is one of the best iso graphics cards   out there it is very fast and is highly  compatible with everything you throw it   unfortunately this card seems to have only 512  kilobytes of video memory but do you remember   all that memory modules well i could get some  memory ics from there and transplant them onto   this card and upgrade it to one megabyte for  higher resolutions however for dos gaming these   512k are already absolutely sufficient i'm  super glad about this western digital card   okay and the next one is another iso vga card  now by umc yeah and this is a umc indeed this   card is quite rare but also quite slow if  i remember right however for a nice 286 it   should be absolutely sufficient the card  has also 512 kilobytes as far as i can see   but look at the jumper wires probably for the  memory configuration that looks really funny   anyway i think that i will make some benchmarks  with this card as well since i only remember   that it was slow but i don't remember how slow  if you are interested write into the comments if   you want to see a video with some isa vga  cards benchmarks in the future next sdram and indeed some 100 and 133 megahertz  sdram modules from 32 to 256 megabytes next package says three times painting  socket 370 one gigahertz copper mine yep three times one gigahertz cpus another pci ultrawide kazi controller with the  bios rom so it can boot from the connected drives   and the same controller once again now i should   have enough scuzzy devices for the  all projects i ever planned to do and isocom industrial must be  some kind of serial port adapter   hmm i think this is not a serial port adapter i  would say that this is some kind of controller   with proprietary interface for some machine  or medical equipment there are some jumpers   for the rq and eeprom and a microcontroller  the port looks like a usual serial port but i   think this is misleading there is also an led and  some kind of push button well i have no clue what   this is but if you know what this card could  be please write your ideas into the comments   and another try here we should  have a pci serial controller   yes and this is a serial port controller as  i know them from some industrial machines it   has two serial ports on the bracket for external  devices and multiple internal headers such cards   were pretty common in the telecommunication  switching computers and such things and are   really handy if you need a lot of serial ports and  we are diving deeper into this seemingly endless   box of hardware and getting a 486 new battery  plus neat fixed package let's see what's inside looks like a soccer 3 486 mainboard indeed  it has a voltage regulator for 3 volts cpus   256 kilobytes of cash it uses the wider  sram ics 4 times 64k many boards from the   days had more common a times 32k sram ics  but that have taken more space on the board   and on very late 486 boards such why the 464  case ics were used instead to cut the pcb costs   and on the back there is a jumper wire which  goes to the keyboard controller well all in   all it's a nice very late pci 486 mainboard and  maybe i will take care of it in one of my videos and obviously another 486 main  board no post is written on it okay another 486 pci mainboard from about the  same time as the previous one also this board   has a voltage regulator to support 3 volt cpus  this board has a coin cr2032 battery which doesn't   leak so there is no damage from it it also has an  integrated ide controller 128k of cash everything   looks clean and there is no obvious damage to see  on the first launch also on the back the board   doesn't look to be damaged or heavily reworked  well i'll have to take a closer look at it later okay next package is a main board again   this time it has to be a super socket  7 with some kind of keyboard error okay a very nice and compact super socket  seven main boards built around the famous   vaya mvp3 chipset i think that i have the  same board in my to be repaired box already   it is always good to have two of the  same boards at hand to compare all   kinds of things during the repair so  it is great to have this one at hand this board have seen some keyboard connector  rework but as the description on the package   have set that didn't help i guess in this donation  there are so many main boards maybe i should make   a repair-a-thon once again last time many of  you seem to have a lot of fun with it so why not okay what's next als 4000 pcis on a  pretty simple sound cards but if i   remember right this one does work in  dos but i'm not quite sure about that next one is an isa lpt port however this  is actually a scadi iso controller which   was used for external skz devices like  scanners and cd-roms back in the days and here we have a soundblaster ct41cm iso  sound card yeah i know this card pretty well   it is also called sound blaster 16 vibram and is  very late creative sound blaster 16 saw on card   the sound cards was highly cost reduced and  has no yamaha opl3fm synthesizer anymore it was   replaced by creative's own cqm implementation  which sounds very odd in the old dos games   on the good side however this card has a clean  sound and a very good compatibility it usually   just works and if you don't mind to have  the odd fm sound this card is a good option   and another iso sound cards now with the  als 120 chipset this is also a really   uncomplicated sound card which emulates sound  blaster pro and sound blaster 16 both in stereo   that was absolutely not common for the sound  cards back then not even creative's own sound   blaster 16 could do sound lesser pro in stereo  and all the clones could only sound blaster pro   but not 16. on the bad side is however  again the custom opl3 implementation   which sounds quite different from the original  yamaha sound but it has a wave table header for   an additional add-on cards and general midi  support the audio quality on these cards is   however usually mediocre still a high compatible  and reliable sound card for a simple retro pc and another creative sound blaster 16 value  model ct 2770 yeah this is one of the earlier   models of the cost reduced soundblaster 16  value series on the good side is obviously   the good compatibility and unlike the later 16  video revisions this one has still the original   yamaha opl3 synthesizer integrated into the  chipset here you can see this opl inscription   unfortunately all the later revisions like  the ct4170 which i showed before replaced it   by the cqm chip and didn't sound right in the  older games anymore on the bad side compared to   the first generation of the sunblaster 16 was the  reduced audio quality missing wavetable header and   the notorious hanging notebook when using external  midi devices like the mt-32 for example this card   has some botched wires on the back but i will  have to check out later what they are exactly for   boy oh boy this box seems to be really  endless stillbore obviously sent me   hardware which would be enough to fill three  channels with content for the next three years   and the next package says industrial socket 7  works supports k6 500 k62 voltage auto let's see so this board already seems to have some  intel pentium mmx cpu in it what's this a pentium mmx200 okay the board has a dallas 12887 rtc module   if it's empty luckily i have a good  replacement the board is a mostron p55ad revision 142. the chipset is ali m1543 m1541  it was a very successful chipset for the super   socket 7 main boards it was also known under  the name eledin 5 and was made by ace or labs   it supported front side bars of up to 100  megahertz and important agp which was a standing   out point of the super socket 7 main boards  however this board seems not to have an agb   slot at all only three normal pci slots and one  another strange pci with an offset to the others   i have no clue what this is used for and i never  saw something like this before usually i would   expect an agp slot here on a normal super socket  7 board but this board doesn't seem to be normal   if you know more about this slot please  enlighten me in the comments other than   that this board looks like a normal super socket  7 main board and i will definitely try it out soon   oh wow we finally reached the bottom of the box   i already stopped to believe that there is  a bottom at all this is another main board oh yes the note says not tested no battery and  here future 286 12 megahertz plus ram controller   on board rare yes i remember steeper sent me some  pictures of these boards so let's see what we have wow a great looking 286 main board  already equipped with some memory this cpu is an amd 286 12 megahertz and the  crystal oscillator here in the corner confirms   it with 24 megahertz which are divided by two  feeding the cpu with 12 megahertz eventually   the math core processor socket is empty and  in the future i could use that 287 xl fpu here   which tibor put into this donation as well as i  mentioned this board has already the same memory   populated it seems to have four times one megabyte  sim modules which would mean an incredible amount   of four megabytes of memory that's huge for a  286 but that's not everything look at those ics   down here each one is 128k and there are eight of  them which brings the total memory size to warping   five megabytes and here on this side those  four ics are probably the parity chips   this memory configuration would cost quite a lot  in the end of 80s almost nobody had so much ram   in the pcs back in the days this main board  has some damage from a leaky battery so there   is definitely some work to do well for this video  i was planning to take a closer look at least on   some parts in this donation but it is so huge that  it took much more time just to take a brief look   at it i will need a lot of time to get through all  the hardware to check it and repair if needed but   i would say since this was the last and the  oldest main board in this box i would like   to take care of this one first so join me in  the next part if you want to see if this main   board is working at all with the corrosion there  is definitely some work to be done anyway but   we will see if it hides even more surprises i  would really like to thank sibor once again for   this amazing pile of hardware this will give  a lot of material and ideas for the videos in   the future and even if i will not be able to  make a video about every one of those parts   you definitely will see the one or another used  in my retro builds or repairs once again the first   of such videos will follow soon so keep an eye  on the releases please write into the comments   what you would like to see from these parts  in the future or if you have some information   on some of this hardware which could help me to  make such videos and so far thank you and goodbye
