Re: Superdos in upper memory
Not sure what you mean. DOS is always in the upper part of address space, was this just a switch on the chip selects? Maybe he means that it was patched to have it's buffers in the $E000-$FEFF area, I guess that could work if you have a 64K machine and on cold start copied $8000-$FEFF to RAM. Humm ...

Re: Extra PCB fitted to Dragon 32
Quite a co-incidence this discovery, given my other thread about display quality! Like Alastair, I'd be intrigued to know which Dragons this would work with. Might it already have been done on the later issue5/6 boards, which is why they have a better quality display? Or is it better still? I love ...

Re: Extra PCB fitted to Dragon 32
Right having bought that self same non-working Dragon, thanks RWAP, I didn't realise it was boxed, and though the box was a little scrappy it had a decent set of pollys :) It works now BTW, had to supply a PSU board, change the pot behind the power connector and change the standoff on the addon boar...

Deltados manual
Hi all,
Does anyone happen to have a copy of the manual for the DeltaDos cart, I've just picked up one from ebay, but can't get it to format a disk, I think having the manual would help greatly.....
Cheers.

Re: Blank Cartridge board on ebay
Yes, it is. I do prefer PCB Artist, because it's free and far easier to use than eagle, in my opinion. Eagle's not too bad once you get used to it, and is actually pretty reasonably priced for the hobbyest eddition. Also PCB Artist seems tied to one board house, which is deffo a disadvantage, can y...

Re: WANTED: 5.25" disk drives
They keep reseting pin 34 (DSK CNG / READY) randomly which linux then reports as the disk being changed whilst I try to read it. The jumpers are all set for AT mode working (DS1, DC etc) but I think the sensor needs replacing. Yeah that sounds like it could be the problem, also check for dry solder...

Re: WANTED: 5.25" disk drives
