IC Test Card: Made by a Japanese company called Fairy, given the
20-pin ZIF socket that (I assume) goes with this, I imagine it's a
tester for TTL logic chips. Most of the card's logic is buried beneath
black gloop with black cardboard over the top, so who knows what's
under there - the 40-pin chip with the 'test OK' sticker on it has had
the markings ground off too. Anyone heard of one of these or have
software for one?
Have that card. I think I have the software somewhere but I where
eludes me right now.
Z80 Card: Actually a "Z80 Card II" made by Creative. Presumably
software exists for one of these somewhere still. No on-board memory,
and 4 unknown DIP-switches in the lower-right corner. CPU is Z80-A,
card seems to have been made in late 1982.
Seems to be pretty much a standard Z80 from that period
ROM Card: No idea what this is; presumably the 6 ROMs (2716 chips)
contain utilities that could have been accessed under software
control? No idea what the switch at the rear edge of the card does
either.
It's what it says, a ROM card. Dates from the Apple II, II+ days. When
it first came out the cards had Applesoft on it. The switch allowed
your II to start up either on the motherboard ROMs or to override them
and startup on the cards ROMs. Later people often movedthe ROMs over
to their motherboard and installed their integer basic ROMs on the
card. Since all 6 sockets are full then it likely has some version
of Applesoft. The card has a couple of solder jumpers that allows you
to either use Apple ROMs or EPROMs.Looks like the original swith has
been replaced. Card will work on a II, II+ or IIe but not a IIgs.
80-column card: Marked as 'Chinex' and made by Creative, presumably
necessary software for this still exists somewhere? Any ideas what the
'middle' connector (with no cable attached) is for?
ZIF-socketed card ("unknown_04.jpg" on the website): The ZIF socket
is a 28-pin unit. I'd say it was a programmer, but wouldn't it need an
external 24V (??) supply if that were true? The 40-pin chip is marked
as "S6821P", whatever one of those is. The first 3 of the switches are
labelled as '16', the next 3 as '32' and the last 4 (overlapping by 1
with the previous 3) as '64'.
AP64 EPROM burner. You can download a PDF of the manual from my website
at http://homepage.mac.com/wayne_stewart/FileSharing1.html
Card with remote pushbutton switch ("unknown_03.jpg" on the website):
All TTL logic on board, ROM is a 2716 chip. Underside is labelled
"Wild card". Anyone seen one of these or know what it is?
