I did a 'quickie' retouch on the photos #2 and #3..
here they are.. but the quality just wasn't there for a crisp image.
Indeed there appears to be a SIMM slot at the inside end of the card!
Depending on the BIOS date, it could accept up to 8 Mb or 16 Mb of memory. evasive
has sharp eyes!
That hanging power connector goes to a Molex lead from the PSU. There are two small white pin connectors near the power connector's merging on the card.. possibly for the front panel connections and maybe speaker? It should fire up, if still working, on its dedicated backplane mobo. Add some memory, 72-pin type. Have seen many of this type, but this is a new one. From the relative size of the card versus the fan and CPU socket, I'd venture a guess as being an AMD 486 /DX33 in the older 386 chip die configuration. Too small for a standard 486 chip size.
F@H.. to solve mankind's maladies.. in our lifetimes!
