Hi Jeff,
>> Which is what led me to believe the code was not Z80 specific.
It's not, and I had trouble getting any of the sources to assemble in any of the standard assemblers that I normally use with CP/M 2.2. I think that the intent was to port the code later on to the Intel processors, so it is in a form that would make that easier?? Just guessing. BUT, it leaves those of us who use CP/M 2.2 in a quandry.
I just translated it (the single CF version) as best I could, and got it running with CP/M 2.2. It seems to work OK, but it was a lot of work.
I just wish that the .HEX files had been included in the distribution. Then it would be a fairly simple matter to regenerate the code in a form that would work for whatever configuration one is using.
