The best way to program 2708's is with a Cromemco Bytesaver in an S-100 system (I think someone already said that). There were 3 versions of the Bytesaver: -Bytesaver I (2708) -Bytesaver II (2708) -32K Bytesaver (2716's) The primary difference between version I and version II was that version II had "bank select" and could much better coexist in a system without removing RAM memory to make a "hole" in the memory map. In fact, with version II of the 2708 bytesaver and the 32k Bytesaver, you could have a full 64k memory map of RAM and both Bytesavers (2708 and 2716) in the machine at the same time, and the programming software could do the necessary bank switching to manipulate the memory map. Definitely try to get the Bytesaver II for 2708 burning. I have software to do the programming as well, and there were some Bytesaver burning programs in the CP/M user's group. There was a listing and paper tape that came with the program (the listing is in the manual), but it was crude and rudimentary, however the "burn nucleus" can be used with a more sophisticated front end.
