Last time when I went to pick up some more PET computers, I browsed around all the computer stuff everywhere: on shelves, in drawers etc. I found two PC related items (sorry, no pics) that I wonder if anything can be said about, or if they would be worth trading:
1. It looks like a serial port interface for 8-bit ISA bus, judging on the number of pins. What made look twice was that it has a MOS 6522 VIA chip. I know this is used for various applications including serial communication on different 6502 based systems, but was it commonly used on serial interfaces in the (IBM) PC world as well? There was one external connector, a male DB9. I thought all serial ports were DB25 back in the days of 8-bit ISA, if that was what it was. My other guess is that it is some early joystick interface for using Atari-style joysticks???
2. A 16-bit ISA floppy/IDE controller that also had headers for DRIVE 0 and 1, if I recall correctly. I have a vague memory of having seen that before, but I can't remember its use. Is this a bog-standard item that in untested condition isn't worth the shipping costs? Sorry, I didn't recall the brand.
Those were the only items directly aimed at the PC platform that I found at a brief look. Since there are a few Victor computers lying around, do those also have the ISA bus and the cards might be related to them? Considering a few boxes full of shrink-wrapped packs of 5.25" HD floppies, which neither Commodore PET nor Victor Computers used, I suppose the former computer store catered for local PC users as well, but in rather limited scale.
