The font you show is a 8x8 CGA font. A CGA font is 8 bytes per character at 256 character, i.e. 2 kilobytes. Your ROM chip has 8 kilobytes, and your card is very likely to use one of the four 2-kilobyte parts you obtain when dividing the 8 kilobytes into 4 equal parts for CGA display. If you obtain …

Recently I got dual Hercules/CGA clone ( this thread ). This card has a empty socket for a 2764 ROM chip for a character ROM. I have some AT28C64B-12PC ROM chips and a TL866A but I don't know to proceed. What BIN file I should be burn in the EPROM chip to get spanish keyboard (see the picture)? …

I have a problem with this board and the copro (287XL): it isn't working. The board works properly without copro. The copro is ok too ( I have another 286 board to test). When I plug, the copro is detected for the mainboard, but If I run the different tests I havr ( Checkit, mcpdiag) the copro fails …
