I have released LLama2.c64 - an LLM running on a C64 with 2MB REU. It runs the Llama2 LLM architecture, using the tokenizer and weights from the Tinystories 260K model.
It's a storytelling model that tries its best to spin your prompt into a story, as if told by a kindergarten child. It will generate one output token about every 8 minutes.

Finally released the firmware for Pi1551! https://github.com/ytmytm/Pi1551
This is a Commodore 1551 cycle-exact drive emulator for the C16, C116, and Plus/4 family. It is based on Pi1541, but reworked for the TCBM/1551 world.
It supports D64 emulation of 1551, including switchable ROMs and 1551 RAMBOard expansion.
Like with TCBM2SD you can also read D71/81/80/82 disk images or reading the files di

Here is another project I've been working on: https://github.com/ytmytm/1551-RAMBOard-FirstBank
It's a RAMBOard, but for 1551. As far as I know this is the first of its kind. Just like on 1541-II a small daughterboard that plugs into the ROM socket. It adds 8K of RAM ($8000-$9FFF) plus 8K of extra ROM space ($A000-$BFFF).
There is a patched ROM which uses the extra RAM as a track cache: it reads t

"From Stettin in the Baltic to Trieste in the Adriatic an "iron curtain" has descended across the continent."
An idea for C16/116/Plus4 GeoRAM/NeoRAM-style battery-backed RAM expansion
These computers allow only single registers to be mapped, there is no way to map in whole RAM page into I/O like GeoRAM does on C64.
Let's try something different: …
