I recently got a set of two Apple II expansion cards thatI would like
help identifying. The two cards are connected together with a four*
pin ribbon cable.
The first card has "Giantek Technology Corp." and "Super E-Card" printed
on the board. The card consists of five ROM sockets. Four of these
sockets are filled with EPROM chips labeled ROM-1 to ROM-4. The ROM's
are also labeled in what I believe to be Chinese. There is also an
empty ROM socket after ROM-4. There are two smaller chips with the
markings sanded off and a larger 20-pin chip hideen under a plastic
coating. This last chip has a paper label also written in Chinese.
The second card has six EPROM chips labeled ROM-1 to ROM-6. The ROM's
are also labeled in Chinese. There are six smaller chips with the
markings sanded off. In addidion, there three other chips. One, which
really confused me, is a Z80A CPU chip. The board's configuration does
not resemble any type of CP/M card that I have seen. The second chip is
marked "HM6116P-2". The third chip is a socketed with "M5L8255AP-5" and
"84A609" written on it.
An Internet search reveled that Giantek Technology Corp. is now a large
manufacturer of LED display boards. Further searching revealed that in
1983 Giantek developed the first "Chinese Generation Interface Card" for
the Apple II. That might mean these cards are a Chinese screen character
Any help would be appreciated. I do not want to plug in these boards
until I can figure out exactly where they should be placed.
