And Zilog defined its own mnemonics. I think DJNZ is the Zylog name for that
instruction. Back around 80-84 I did some coding on a Z80-based EPROM
programmer. In the late 90's I did some updating of code in a Z80 scale
("weigh meter") controller. The Z80 was what CP/M was written for, and then
ported to 8086, upon which MSDOS was based.

I remember going to the demo units at RS and writing:
10 print "TRS-80 sucks!"
20 goto 10

I had an Amiga 1000, which had far more power than Win 3.1 at the same time,
running a full GUI and an app in under 256 kB. We're spoiled, now!
Had the Amiga displaced the PC (ie. had Commodore had a real marketing group),
we'd probably have seen BF1942 on it 10 years ago!
