It's possible. Perhaps it's a TTY en/decoder to allow deaf persons to use
their Apple as a teletype?
There were systems that allowed many computers to be connected to one so
that a teacher could do a lesson on the main computer while the students
watched along on the slaves. Something like that.
What does it use on the PC side? It clearly is some kind of TTL level
interface. Do I need a special PC card taht I've not got (or at least not
found yet?)
Hmmm, good question. Now that the drugs from the visit to the dentist
have worn off, the PC Transporter allowed you to hook PC drives to an
Apple ][ and read/write PC disks. It didn't actually have a connection to
the PC itself.
I have a box made by Rana that allows an Apple ][ to run PC programs.
The box presumably has a separate computer with an 8088 CPU and two
double-density disk drives. Maybe this is the interface card for such a
box? I am headed off to my storage place to pay the monthly dues, so I'll
take a few moments to check it out and see what the interface card is like
for that.

Sellam, you were my best hope for identifying these
boards. If you've
not seen them, I guess nobody will know them :-)

If I had to guess, I'd think this one was possibly some kind of 'network'
interface. A slow-speed network using asynchronous data transmission.

From the name (Advanced _Text_ Systems), I
wondered if this was the
interface for a daisywheel printer or something similar?
I've got a
couple EPROM programmer boards, but I don't know if I have
either of these. I know with one of them I got the software.
My guess is that these boards are to allow several Apples to share
something else. Maybe a hard disk. ICE Apple Cold Boot Adapter. Contains 6116 RAM,
EPROM, TTL glue, and a 26
pin header
ICE Multiplexor (sic) Host Adapter. 6116 RAM, EPROM, TTL, 20 pin header
Interesting. Again, never heard of them. They sound like some sort of
terminal server system, maybe allowing an Apple to be shared? Naw, that's
silly. I wonder if the 'Cold Boot Adapter' links to
that KONAN card and adds
a hard disk to the Apple. The Cold Boot part meaning the Apple can
boot from the hard disk without needed a boot floppy. I am probably
wildly off, though
I was thinking something similar actually.
Apple PC Link Interface. Contains an EPROM, M58725,
TTL glue and
buffers. Also a 20 pin header.
Sweet. Does what it says, let's you link an Apple to a PC. Who is the
