Flex PL9
Does anyone have a stack of flex disks that might have a copy of PL9 lurking in it? Although originally by Windrush Microsystems for early 6809 flex commercial systems, a version of PL9 was resold for the Dragon by Compusense. It's a language halfway between assembly and something like basic09 or pa...

DREAM Editor Assembler (tape) manual
After a request on the Dragon FB group from Kataja Kirjuri, I've made a scan of the original DREAM Editor Assembler manual as supplied with the tape version.
One plain PDF, and one searchable (much larger PDF) attached here in a zip file.

Re: SAM replacement - nearly there
Nice reductive action. Fingers crossed for glitch de-glitch.
Is that 98 with a stu-banker integrated?

Re: SAM replacement - nearly there
My thoughts were making it do something gime or 6829-y with an external sram and a latch / transceiver. Then you could meet your "it's still a dragon" test but do nice os9 level 2-y stuff. Essentially a modern integrated version of the Bob Hall MMUs. However, it sounds like space is probably at too ...

Re: SAM replacement - nearly there
That's super cool.
Really hope the density option pulls back a load of macrocells, as some headroom on this design would open up some amazing possibilities.

Re: OS9 User Group Disks
Oh, interesting... One issue of Dragon Update in the summer of 1990 refers to Newsdisk 23... and lo... on there, there's a debugged (hopefully) initial draft of the complete design article for Bob Hall's CoCo3 compatible Dragon MMU board... and all the OS9 L2 modifications to run it.

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.
