I have an EGA card that I need to identify... It is a half size, 8 bit card. Accessible form the exposed end, it has one female DB9 connector, 2 RCA connectors, and a bank of 5 DIP switches. The most distinguishing markings on it is a sticker across a large 40 pin DIP IC that reads "Sigma Designs, Inc. EGA 480". It is a yellow sticker, and has emblem that looks like a filled in letter D with a greek sigma inside of it. There is also another (for a total of 2) 40 pin DIP IC. There is one 68 pin PLCC "CHIPS P82C431" ic in the top left corner, a 84 pin PLCC "CHIPS P82C434A" ic in the middle of the board, and another 84 pin PLCC "TAG 8732" no brand chip in the lower right corner. There are 8 "D41464C -12" 64K? ram chips in the middle/lower left side of it. There is a row of 74LS244 and 74LS245 chips across the bottom close to the card edge connector. There is a 32 pin female plug at the center top of the board. There a 6 pin header with pin 2 cut off at the top right of the board labeled P1. Looks like a game connector? There is a 3 pin jumper labeled P2 under P1. There is another 3 pin jumper labeled P3 in the lower right of the board. There is a "27256" eprom in the lower center of the board. On the front, there are markings "P/N 150-318 EGA 480 Rev 1.50". On the back there is "KALEX K668 94V-O 2487". Thats about all I can say about it. Can anyone tell me who makes (made) it and a phone number? An explanation of the 5 dip switches would be great. I would like to install it in an XT clone, but I am not sure if the BIOS supports it and how to overcome that... Please send replys via email, and I will follow up with a summery. My home sight is changing names from to "seattle", if mail bounces please resend using the new seattle name.
