- I don't recall the exact chip number, but I do know it is a
- 64K-byte EPROM
- but the ROM image was 32K-bytes. I haven't tried to contact the
- author to
- find out where in the 64K space the ROM image goes. Please let me
- know if
- you find out. <<
-
- The ROM image was designed for an 27C256 EPROM, as the Oktagon
- only has 32k ROM space in its memory map.. As nowadays 27C512
- EPROMS are cheaper than the older 27C256, most new boards have the
- bigger ROMs installed, but 32k are just wasted.
- To use 27C512 ROMs, the code must be burned in the UPPER half (the
- UPPER 32k) of the ROM.
