Help ID Card: Giantek Chinese ROM Card?

["Brian A. Davis" <badavis@nbnet.nb.ca>]

Hi;

I recently got a set of two Apple II expansion cards thatI would like 
help identifying. The two cards are connected together with a fourteen 
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 
generator.

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.

Thanks,

Brian
