Repair issues

Many 468s used Mostek MKB36000 masked ROMs that can suffer from "ROM rot". It may be necessary to replace the 160-0459-01 and 160-0759-01 ROMs with 2764 EPROMs through a 2364/2764 adapter. Another option might be using the MCM68766 EPROM.

replaced ROM by 2764 with homemade 2364/2764 adapter
Result of bad ROM by verification-check.
