2332 2364 Rom To 27C64 Eprom Adaptor
RECEP UNAL Sep 04,2025
This project has been tested and works for the Commodore C64. I'm using the adapter in my project instead of the faulty 901227-3 (Kernal ROM) and 901225-01 (Character ROM) on my own Commodore C64.901227-3 (Kernal ROM) is the 2364 ROM, and 901225-01 (Character ROM) is the 2332 ROM. I copied the original ROMs for my C64 from "https://zimmers.net/anonftp/pub/cbm/firmware/computers/c64/index.html". Since the 2364 ROM images are 8 KB, they can be written directly to the 27C64. Since the 2332 ROM imag...

DigiMAX Mk2
E. Aug 26,2025
This is an upgrade over the original DigiMAX, featuring less-expensive chips, channel auto-switching (including lockout to allow for manual/deliberate switching), and a more modern design in general.This design combines the basic features of the original DigiMAX Mk1 with the 8BSS project, all in one tiny package, providing two 8-bit DACs and two 8-bit ADC's on the User Port, with a new auto-switching function which makes writing or reading sample data as fast as if the chips were on the Expansio...

C64/C128 Internal stereo SID
E. Aug 25,2025
This is a simple two-SID-chip plug-in board for most Commodore 64's and 128's, including the plastic-case C128-D.The second SID can be placed in any I/O page the machine supports, and it can be moved off of the base of the I/O page you put it in and placed at any other $xx20/40/60/... section therein, if desired. You can also put it in the $D400 page just above the primary SID.This board has provision for the "background noise silencing" hack also, to reduce the digital bus noise the 6581 tends ...
