But if you get no other help and you can wait a bit, I believe one of my old EPROM programmers can read the 8048/8748 with the right adaptor, and the schematic of that is in the manual. I also have a working (I hope) HP9915. So I could have a go at making said adaptor, extracting the 8048 from my HP9915, and readng it out. You would then have to find somebody who could program the ROM image into an 8748. -tony
