These are the Eproms as copied from my Triton on 8th / 10th March 2021.

***** WARNING *****

These EPROM are not standard issue

! They have be modified !

The mods are to the monitor and the L7 BASIC to add a floppy disk and file system to the BASIC and monitor , an eprom programer and eprom emulator to the monitor and finely a programable graphics generator to the BASIC.

I programmed them more than 30 years ago.

The four letters/numbers on the end of the file name are the 16bit checksum.

The should be installed as follows:-

MONA72 0x0000 IC21

FASTVDU 0x0400 IC22

BASIC.MOD 0x0800 IC23

MONB72 0x0C00 IC24
