Re: Atom Floppy

Hi, can I have the same connector as 1024MAK for my internal floppy drive controller card.
All my Atoms have a male(pin) external connector and a female(socket) internal connector
just like 1024MAK's and the Roland board. An old internal 32K RAM board I had also fitted this way.
Thanks.

Re: Atom Floppy

Hi, yes I would be interested in just the floppy controller board. If you would let me know what the shipping costs would be then I can arrange payment by PayPal or by any other means.
Thanks,

Re: Matchbox sized 6502 / Z80 / 6809 Co Pro

Hi, yes it does have the extra decoupling capacitors added by Jason and there is nothing attached to the 1MHz bus.
I originally used a cable the same length as my Acorn 2nd processor but it was
unstable so I shortened it.

Hi, on my Master 128 I had to shorten the cable to 2" to get reliable operation with my Matchbox Co Pro.

Re: Master Compact with MMC - odd behaviour

Update: the enhanced version of Strykers Run can sometimes crash on a Master Compact and also will not run on a Master 128 fitted with MOS3.5. A bit of dis-assembly reveals that the enhanced version reads a data table at &C000, which is either RAM or ROM. This could account for the problems with oth...

Eventually, but I wish to sell all my Master Compact systems first.
The upgrade will be about £69 and will include the switchable

Hi Phil, I did intend to make the FORMAT program more flexible but I've not
had the time. I will post a disc image of the modified programs when my
Atom is up and running.

Hi, *LOAD the FORM40 program, change to *DRIVE 2 and then LINK the
execution address. I have a Cumana 40/80 track and 3.5" drive in my
Discpack. I modified the FORM40 program to format 80 tracks i.e. FORM80
and did the same for the VERIFY program

Re: OS version affects RGB output?

No, I am trading as 3071Michael. Stephen, do you have the original MOS3.2
ROM, and if so try that with your Master 128 + GBS8200 combination. I have
plenty of the MOS3.2 ROM's if you want one.
