Perhaps you can try the super.rom and modified amsdos80.rom?


Hi Zhulien

do you have a link for the super.rom and modified amsdos80.rom?

Thanks    Ray

RTC stands for RealTime Clock. It's a clock (ie: with the actual time, not just a ticker) that continues to run even when the computer is powered down. It's useful for many things such as putting time stamps on files when they are created/saved.

So to eradicate this bug, you just had to Reset bank by putting #c0 to port #7f before to connect Asic i/o page, am i right ?


Sorry to UP this old conversation but...


What about softwares who are using Asic when in 7FC2 (or upper equivalent)? As you cannot 7FC0 before accessing Asic, all Asic access will occur in B5 (or upper equivalent)


As a result, I made yesterday a small test. If modern extensions may be fixed in the futur, the code will run further


Code: [Select]
Asic Off

ld hl,#4000
ld bc,#7FC4
out (c),c
ld (hl),c
Asic On
ld (hl),l
Asic Off
ld a,(hl)
or a
jp z,ExpansionKO

use RASM, the best assembler ever made :p

I will survive

Late to the party: Does anyone know how to order an X-MEM board these days? The original link doesn't seem to work anymore (looks like a blank site).

Often.
Some Amstrad's doesnt allow to exchange ROM7.

When you have a mass-storage device like M4-Card or XMASS, than AMSDOS on ROM 8 could be a better idea.
