Thanks to Bram. This is v20 version, different from the S30 I have. Some internal photo’s and a d64 dump of the eprom. Another difference is an additional DIN connector, i pressume for connecting a printer. This one is not part of my collection, not yet 😉

…”This one is not part of my collection, not yet 😉….’
You are the first in line! 😀👍
can somebody give a schematic or make hires photos of the pcb please
I’ve already posted some photo’s I got from Richard Lagendijk, and some of the S20 version of Bram. Both posted on the blog (look for all the Final Cartridge category articles). Unless I can get my hands on another S20/S30 I will not desolder my version and preserve it als working in my collection, sorry.
Thank you, i already rebuild a working v10 board with the help of richard. Only need the “Special” manual
Photo’s provided by Bram and Richard are already online in blog articles. Will nog desolder my FC internal, unless I find another one 🙂
Not sure if this blog is still active, but I discovered that a C64 I was handed over a decade ago (but just got access to it since my last re-location of my work room) has a V20 built in.
It does not have the extra 5-pin DIN connector on the back though.
The opening post of this blog mentions a ROM dump, but that’s a D64 format. Not very useful if you want to burn the two ROM images into the two separate EPROMs required on th PCB.
The left ROM (the 2764) contains the FC version of the BASIC ROM, the right ROM (27128) contains both the original KERNAL and the FC KERNAL. The A13 address pin of the 27128 switches between FC and stock ROM. The FC ROM switches between BASIC ROMs via the PC# pin of CIA 1 via a timer (4024B).
I took the PCB out of my C64 to do the reverse-engineering.
I also made a ROM dump of both EPROMs.
Don’t know how to post schematics or the ROM dumps here, though.
Hi, the blog is kinda inactive, still collecting but other things take up my time!
You can open the d64 with Vice of Dirmaster to get the kernals. You can send the schematics and rom dumps to the blog e-mail and I will publish them with reference to you. Richard Lagendijk has a commodore blog as well, and some references to another user (Super Neotendo) and his work on reproducing the Final Cartridge Internal (https://www.commodore-info.com/cartridge/item/final_cartridge_internal/en/desktop)
