The CoCo Discord server
Quite a lot of people these days are less than enamoured with Facebook, and with much day-to-day Dragon discussion going on on the Facebook Dragon users group, that can leave people 'out of the loop'. An alternative forum for real-time discussion with sensible sub-sections and a good community of kn...

Re: Home Computer Museum Helmond Dragon 64 archived disks
And the Dragon 64 also had a 'mystery mod'. A twisted pair emerging from a little hole next to the cartridge port, going to a female header plug... I didn't get in to opening hardware, so what this little 'switch, if you plug one in' was doing is a mystery. One for next time.

Re: Home Computer Museum Helmond Dragon 64 archived disks
A little blurb to accompany this archive. Very interesting set of disks... the Dragon 64 in question was obviously heavily used under DragonDOS, OS9 and Flex for document preparation, graphics and entertainment. The twin DragonData disk drive unit had two replacement 80 track double sided drives fit...

Home Computer Museum Helmond Dragon 64 archived disks
Results of a day and a bit of archiving of the most interesting of the large number of Dragon 64 floppy disks in the Museum's collection.
Thanks to Bart van den Akker for the opportunity to capture these! A visit to the Museum is very much recommended if you get the chance.

Re: OS9 User Group Disks
Nice! Will have some fun looking through those.
Though VDK, argh... The toolshed package os9 utility which allows exploring, extracting files, changing RBF disk images from windows or linux only likes headerless! So headerless .DSK, or .IMG or .OS9 is much more convenient!

Re: Wessex Wyvern expansion box?
More interesting is that EliteCalc works on the Dragon! That's a CoCo cartridge I thought?
Actually no - scratch that. It seems that Microcare 'Elite Calc' did have a Cartridge version.

Dragon disk drive RPM checker
Here's a Dragon-ised version of Robert Gault's disk drive RPM checker that I posted on FB some time ago. Use is obvious... load using a working drive, Gotek or drivewire, and then run with the drive for testing attached and a disk inserted. Note... Dragons 32s have two different possible main crysta...

Re: Dragon 64 motherboard replacement
I'd be suspicious of the 3.3v signal level output-ness of the CoCoSDC. The CoCoSDC design doesn't have a dedicated voltage regulator to bring supply down to 3.3V from the Dragon's 5V. It uses a regulator on the SD card reader module. Try measuring the 5V line on the CoCoSDC and the supposed 3.3V out...

Re: Dragon 64 motherboard replacement
Yeah, if you are getting strange CoCoSDC behaviour, I'd always look as a first option at obtaining and fitting a pullup board.
