Today I received a couple of curious vintage hardware, the first was a bit of a gamble. From the layout it looks like a graphics adaptor, but the DA-15 connector does not corroborate. With little info on the silkscreen and labels I became intrigued by this little 8 bit isa card. Puled the trigger on it, and now I have a more clear picture, the 28 in ic (U1) is a 6264 static ram. The logo on the main ic and pcb, is from a company called "Video Associates Labs". I now think that this thing is MDA for a CNC machine, probably reusable on a xt class pc.

The second piece of vintage hardware is an IBM classic, the iconic IBM PS/1 model 2011 ( @ least for me ) :

The special thing about this machine is a rare PS/1 sound card, besides being a cute little box :

@ last but not the least, a book about the ISA interface, this is a good reference book from 1995, so a bit late for the lifespan of the ISA "standard", and that makes it a very thorough book:
