I think you are seeing the COAST module.

What motherboard is this ? Do you have a mix of EDO and SD-RAM? EIDT: Ha no I presume this is the L2 cache module ?

Any idea what it is?

Broken chips 🙁

It is a some sort of motor controller, that has suffered a catastrophic failure...

One chip two chip, dead chip blew chip. If not motors, some other high power inductive load.

Wow, that's one for letting out the magic smoke 😲

Left a big enough hole to get it back in though, go to grocery store and get a bottle of liquid smoke flavoring and a turkey baster...... 🤣

I loved the boxed versions hardware

Good some parts for rebuilding my Voodoo 3 System

I was wondering what you could be driving that would cause you to detonate a DAC. That would also explain the fuse and external power input on the inner edge.

Love the Voodoo cards casually piled up like it's nothing. 😁
Great haul.

For the PC XT I found an interesting solution, for the video card, I have an 8-bit ISA, which should be a Hercules (or a monochrome one), the connector for the monitor is with 9 pins, unlike VGA monitors that have 15 pins, so to solve I had to find an 8-bit ISA VGA, or a monitor with 9 pin input, or a 9 to 15 pin adapter.

After various searches, I found a fairly inexpensive solution, a connection cable to the monitor, with VGA port on one side and 9-pin port on the other.

Just replace it with that of the monitor, which has two VGA input outputs, and connect the 9-pin to the Hercules ISA 8-bit, while the other goes to the VGA monitor.

There are some early VGA cards that have a 9pin connector, but if that's not what you have in your XT, that's not gonna work. I assume you have some sort of CGA or Hercules card and this will definitely require signal conversion if you want to use a VGA monitor.

Yes, exactly, I want to use an 8-bit ISA card, probably Hercules (or CGA), which has a 9-pin video output. Using the cable I ordered, it will connect the video card (9 pin) to the VGA monitor (15 pin). The only doubt is whether the Hercules frequencies are supported by the VGA monitor, because otherwise I would have to find a monitor that has no problems with those frequencies.

It's not just the frequencies.
MDA,CGA & EGA all output TTL signal levels 5V (If I recall correctly)
While VGA is analog output max signal level is 0.7V maybe 1V.

Ouch, if so and probably yes, I spent money on a cable that will be of no use, honestly I didn't know this Volt thing, at this point the only solution is a 9-15 pin converter, I've seen one used in Necroware, I don't know what it costs but the alternative to that is a VGA ISA 8 bit like trident or gremlin.

Just got the one on the right, it's a bit special!

Is that trackball actually wireless? I see it has some radio like logo next to the ball, but also what looks like a cord? And wouldn't "WIRELESS" be written all over the box?
