From Mihail Zharov To Aleksandr Majorov 19 March 2001

Hello Mikhail! Sunday 18 Mar 2001, at 12:45:18 Mikhail Zharov -> Aleksandr Majorov: MZ> Here is the final version(?) MZ> Here two more streams have been reduced by Pavel Vasiliev.

How did I miss such a piece of code... After all, it’s reminiscent of mask printing... ;) In general, I immediately rewrote it to: ld a,c xor b : and %00000111 : xor b rrca : rrca : rrca : ld l,a -11 clocks and -3 bytes True, this doesn’t quite look like the address calculation procedure...;) [delete] The current result is: ;min: 512 ;max: 1049 ;byte: 107 ps. I need to try switching to 64-character asm. Better yet, redo it ;) Happy connections, Aleksandr...
