Description
UniRetroRom
With this adapter using a 27C256 you can replace a Commodore Vic20 or 64 breadbin rom (2332 or 2364) by simply moving a jumper to emulate the Basic, Kernal or character ROM.
Components:
R1,R2: 10K Ω
R3,R4: 100K Ω
C1: 100nF 16/25v
U1: AT28HC256E
J1 is used to select the rom
open: Rom Characters
1-2: Rom Kernal
2-3: rom Basic
JP2 is used to bring CS2 into the 2332 ROMs.
It is needed only in the vic20 character rom because this computer uses both CS1,CS2 signals.
In the C64 character rom it is optional, while it should not be jumpered if a 2364 is used.
open: 2364 (or even 2332 C64)
closed: 2332 Vic20 only (also works on 2332 C64)
