That's because LDIR (a slow Z80 instructon) will be performed by REP
STOSB ( a fast x86 instruction)


It would be twice as fast on on the speccy if the LDIR was replaced by
a string of LDIs or even a string of PUSH HLs. I wish I still had the
source and a TRS-80 to assemble it on.
(actually I don't, nobody send me any emulators thank you. I've got a
nice surprise for speccy developers coming soon though)
