Wildport Ltd 6522 VIA card. Contains a 6522 (Duh..)
and a '04 only. Has a
lenght of 26 way ribbon cable connected by a permanent transition
connector, other end unterminated. Probably a user I/O card.
Standard 6522 interface. The 04 is to invert one of the Apple's clock
signals to be compatible with the 6522.
Epson APL Board Unit G479501000-0. Nothing to do with
the language, I
think, just an Epson printer interface. Contains a 2708 EPROM + TTL. 16
pin header, presumably parallel printer interface.
I'm pretty sure it's a printer interface sold by Epson for their printers.
I have a few of these.
Apple/PC link interface. 2716 EPROM + TTL + buffers +
M58725 (?). One 20
pin header near back of card. No idea!
I think this is a card by Applied Engineering? Maybe not. But I think it
allows connection to a PC-compatible disk drive(?)
Buffered Grappler+ (C) Orange Micro. 64K RAM (8 off
4864) + EPROM + TTL +
a 40 pin chip (microcontroller?). 26 pin header (printer interface). Is
this a printer buffer card?
Yes, and a nice one.
2 off Communication Board. These aapear to the board
Sellam was
mentioning. 6850 + TTL + P2 PROM + 8304.
Somewhat rare. At least they were hard to come by when I was looking for
another to complete the TelePong demo several years back. I finally got
a second one through the designer of the card.
Heuristics 20A-1. TTL + 2 quad op-amps + 2 quad
comparators + 2708. 3.5mm
jcak socket. I think this might be a speech input card...
Most likely. Heuristics made speech recognition stuff in the late 1970s
and early 1980s. I have a Heuristics speech recognition board (large,
mounted in a hard-shell portable carrying case) with a serial port so it
can be interfaced to any computer with an RS232 port. Circa early 1980s.
