Could you please mention the patch from "Dr. Dobbs Journal #62, Dec 1981
page 519: ZSID Bug and (Risky?) Patch" ?
It changed the byte at 02AE from C2 to C3.
Befor, some adresses of FF80 to FFFF would be handled bad in (A)ssemble,
(F)ill, (M)ove and (D)ump - commands:
A>ZSID
ZSID VERS 1.4
#A100
0100 LD HL,0FF7F
0103 LD HL,0FF80
0106 LD HL,0FFFF
0109
#L100,108
0100 LD HL,FF7F
0103 LD HL,0080
0106 LD HL,00FF
0109
===========================
Some months later, I got a letter from Digital Research which 'begged'
for the allowence to use this patch, which I did...
Greetings, Holger
