Computer Circuit Board Identification request

Here are a few pictures of two boards I have (I am not sure how old they are, but they either came from my old 8088/8086, 286, 386, or my PS2 (all long gone now).
What I need to know is what they are/were and are there any specs out there (I can't seem to locate any): one has a port on the side, one does not. The one without the port has a T.I. chip that looks like an IR programmable PROM
with PGM=12.5 v on it. There is also a crystal with 24.000 stamped on it.
The other one it probably an old video card but it has only 4 resistors on it and one resistor bank, plus four capacitors, and two ic's. One is labeled: 74LS245N ( Octal Bus Transmitter/Receiver designed for 8-line asynchronous 2-way data communication between data buses ), the larger IC is an unmarked 40 pin device.

I tried for half an hour to get half decent pictures of them, sorry for the quality.

I would surely identify those as bombs. You should know better than to post pictures like that on the internets - they have lists for things like this!!!


kidding

I agree with LV -- ironically, I was doing a bit of research on serial interfacing :p

They do look more like a bomb than a breadboard with some LEDs attached to it *LOL* ;-)
LOL We should go post that on toystore websites :D

What use are these old ISA cards? L
Goodhart (author)  lemonie10 years ago
Yeah, that would be my next question....can I use them for anything... :-)
Probably only useful for salvaging components, unless you have a very old motherboard with ISA slots.
Goodhart (author)  whatsisface10 years ago
Well, I think I still have an old 286 in the back room, do you think that would? I haven't had it out for years, it may not even boot anymore.
Yeah probably would have. Worth checking. You could maybe even put a tiny Linux install on it and run it as a server of some kind.

Try the comments here for ideas.

Thanks. I will look into that.

I've got PCI cards which I'll probably never use again... (don't know) L
