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

Thanks for explanations.

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).

Yep, in Slot 6
AMSDOS/PARADOS v1.2 is usually Slot 7?

$3FFE   $3FFD
$33      / $00 - 3.5” / 3.5”
$30      / $00 - 3.5” / 3”
$03      / $00 - 3” / 3.5”

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.

A litle update for the X-MEM PCB:
- add HACK pins (boot rom switch) for deported usage
- add BRST pins (reset button) for deported usage

Will allow peoples to improve the internal CPC intergration or HACKIT feature.

Is this a new version of the great X-MEM or a patch for the ones we have?  :)

Hi Tot0
Am I able to upgrade my old boards ?
Where do I connect the wires to the New Pins ??
and ? What do the HACK and BRST pins do ? ?


Thanks.  Ray

Hi Ray!

The BRST pins (bus reset) are just the same as the MotherX4 reset signal took from the bus to deport it using a 2-wire cable with button.
The HACK pins (hackit) are just the same as the BOOT sliding switch (CPC/ROM) from the X-MEM to deport it using a 2-wire cable with switch.

Those allows peoples using the X-MEM as "Siren Hackit" or embedded into a CPC to have easy access to the features.
It is already possible on the previous versions by soldering wires from the PCB. (require to remove the sliding switch to operate)

Just a commodity for peoples asking me that for this usage.

Thanks,

  TotO.

To use it for the Siren Hackit I assume that one just need to fit the correct lower ROM into the X-MEM and then switch to the new lower ROM or in case of the new PCB just to press the button, right?

However where to get it?

As present a Hackit ROM which seems to be more recent than the one from CPC-Power (just took a quick look).

EDIT: Oh, crap! In this forum I can't even place a ROM here, so let me zip it...
