For legal reasons I must state that this chip is in fact blank. I would never do something as illegal and wrong as writing my own ROM chip for hardware I own, that hasn't been manufactured in 30 years, when there's a company (that didn't develop it) which is actively licensing said ROM. #amiga #cloanto #retrocomputing #eprom #grift #cbm #commodore

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
