Hi Phil,
Thanks! That sure looks like the right one. It is 8080 code, the comments and docs
mostly match what is published from a quick look. I will look into it more when I am home
and have some time. But I do believe that is the "original" as published in
DDJ.
Notes and justification
I started looking for this mainly because I wanted to play with it. I want to actually
use it to write some code and see how hard it is to write usable code with the limited
subset of the earliest released version. But when I started looking I was shocked that I
couldn't find the original. There are dozens, at least, of derivatives in various
versions. Z80, 8088, 6502!, TI 9900 I think and more. Floating point, structs,
optimizers, etc. I personally think this was a VERY important piece of software. I think
the number of derivatives speaks volumes of how important it was. But I couldn't find
the original. I feel it should be preserved. Even the DDJ Small C CD ROM didn't have
it! (They only used 34Megs of the Disk so they had plenty of room.)
Anyway, it looks like Phil found it. I appreciate all the efforts getting it.
Does anyone have any suggestions as to where it should go for safekeeping? I plan on
putting it on my web site, but that is far from an archival solution.
Thanks,
Will
