Rich, I'm not sure what "Imsai Specific" means in this context, but Imsai did sell their own 8k Basic that originally came on paper tape (I think that there may have been a 4K version also). Amazingly, it came with a full assembler output source code listing. The only thing about

that was "Imsai specific" was that it's load and save commands wer

customized for the cassette tape port on an IMSAI MIO card. I have the hard copy listing, and as a consequence of your question, I've just put it into the scanner and will have a PDF file later today. Now if someone wants to key it in, I'll send them the PDF file. The listing is 113 pages long. I do not have the paper tape object code. The version that I have is 1.4 from 5/12/1977. Tell me about the disk system that you can't get working, I have pretty extensive knowledge of some of the Imsai disk systems. Barry Watzman Watzman at neo.rr.com
