Open post ytm @ytm@social.linux.pizza · 8mo ago Replying to @ytm@social.linux.pizza 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 the entire track in one disk revolution, then serves subsequent sector reads from memory. Same idea as the track caching ROMs I did for 1541 and 1571. The project also includes a tiny fastloader wedge (HypaRAM) that calls the code embedded in the patched ROM. The same fastloader is already supported by the latest version of Parobek ROM for C16/116/Plus4. The performance is on par with DolphinDOS - about 27x faster than a stock 1541, about 7x faster than a stock 1551. #commodore #commodore16 #plus4 #hardware #8bit #cbm A 1551 loading a 108 block file with RAMBOard HypaRAM fastloader https://www.youtube.com/watch?v=vWi2URbmIlo 1551-RAMBoard real hardware test
Open post ytm @ytm@social.linux.pizza · 14mo ago Replying to @Megaboz@oldbytes.space @ytm Very cool! How many parameters and how heavily quantized is that model out of curiosity? How fast if you're just generating embedding vectors using the first layer? Just thinking of additional applications that might go faster if you were just doing distance against vectors for similarity matching or RAG or whatever. Neat stuff though, will take a closer look later @Megaboz Thanks. It's not quantized at all, these are all 32-bit floats. First layer run takes about 1.5 minutes with this model.
