mysterious card

mysterious card

[Heusden, Folkert van]

Hi,

I have this mysterious 8 bit ISA card with nothing more then 2 smb-mounted
ic's
and a button. It seems to be something that should force a system memory
dump.
I think I can handle the code-writing, but since there's no documentation I
have
to find out how things are working.
Ok, the question is: does anyone know a place on the web where I can find
specifications of ISA-slots? I need to know what is supposed to be connected
to
the pins (1, 2, 6, etc.)

try the hardware book (hwb)

Or use the official HWB-homepage:

http://www.hardwarebook.net/

(Which, I might add, is a machine here at the University of Umea, Sweden.)

It is supposed to do that!

That sounds like the card that came with an old DOS debugger.

The old 8088 PCs did not have a reset switch. This was so you could do
hardware breaks when the whole system was locked up.

I have one of those lying around somewhere...

Yes, I guess so!

AO> That sounds like the card that came with an old DOS debugger.

Not really. I found it in some high-end UNIX server (non-Linux).

This one triggers the I/O Channel Check pin (pin 1 (at the frame), component
side).
