Like you, I did the same thing on a Z-80 a year later.
Gene, thanks for the stroll down amnesia lane... Back around the same time I was hired to write the OS for a monitoring system for a geothermal test well that used an RC Many years later (just prior to Y2K)A 1802! The funding org was so tight that they could not afford to purchase one of the only assemblers for the thing. So the entire OS, drivers, etc., was all written in hex... One of my friends that worked with that engineer years later adapted the code and project for another purpose. In the mid 80's we got to talking and I boasted that I could now write him a macro assembler for him in 24 hours (he had to buy me a case of coak-a-cola as pay. Well I missed the 24h deadline, but had it working within 36h... Now step forward to 1999. My buddy check his code for Y2K issues and found one. He needed to go back to that ancient code (and the completely hacked together macro assembler I wrote over the course of a day and a half), he dusted off the tarball, recompiled the assembler in a more modern C compiler, it compiled with a few warnings (but nothing sever), made the change to his code, ran it through the assembler, and a day or two later had the Y2K bug patched... As I recall he bought be another case of coke ;-) BTW, I loved that chip. You could do a multi-thread context switch in a single atomic operation. It was WAY ahead of its time...
