Re: WANTED: 5.25" disk drives
Depending on what version of fdparm you have, I have whatever is the stock for SuSE 10.0, the following will work.... # # DragonDos 40 track disk in 80 track drive (eg 1.2M). # for 40 track in 40 track drive, set the 6th column to # 0 instead of 1 (like the 80 track formats below !). # # -5 are for ...

Re: WANTED: 5.25" disk drives
Its for the Dragon, mostly SS40 disks - I have 2 x Chinon drives (1 360KB and 1 1.2M) which now both no longer work and 2 other 360KB drives that use a belt drive mech and the belts are so loose the disks won't spin ! What are the faults with the Chinon drives ? You may be able to get belts for the...

Re: WANTED: 5.25" disk drives
All, My last drive has just given up on me and I don't have any more spares left. Does anybody have a working 360KB (DS\DD) 40 Track 5.25" drive they can sell me - an 80 Track would do as I'm only trying to read the Dragon disks that I have. This may be a silly question but do you need this to be P...

Re: Modern storage options?
The disassembled and partly commented source for SuperDos (and DragonDos) is available. This can be assembled with the assembler from the Nitros9 project to produce a rom that can be used on a real Dragon, and was used to port Superdos to use the CoCo disk controler. Might be worth investigating usi...

Re: CoCoSID
Humm, One of the other places I hang out, one of the Acorn/BBC groups, have designed a BeebSID, that is a C64 SID chip interfaced to the BBC. Should also be pretty easy to adapt to the Dragon/CoCo, as the 6502 and 6809 busses are almost identical. Mind the difficult thing has been getting hold of SI...

Re: Dragon replacement power supply
Good News, kinda What where they thinking when dragondata selected this power supply option, was it just a rip-off of the COCO? Like a lot of things it may have boiled down to 'we can get a bload load of these cheaper than any other option and they can be made to work so we use them' I believe that...

Re: Dragon replacement power supply
If your skills are up to it, you could try drilling out the pop rivets and removing the cover to see if the problem is anything obvious. With luck it may be something that is simple to repair. I'm not sure of the best way of re-securing the cover though: nuts, bolts, and washers from Meccano perhap...

Or at least not until you booted it first....as Nitros9 does use dir to get a list of files.......

Re: Extra PCB fitted to Dragon 32
If you have the ability to take a couple of good quality digital pictures (top and bottom of board) and post them somewhere, I could have a go at tracing the board, which might help work out what it's for.
