Re: Flex PL9

Mace was originally a Flex assembler for SWTPC and other similar traditional Flex machines, before it was ported to a Dragon Cartridge setup, so most likely that disk is simply traditional Flex machine versions of PL9 and Mace on the same development disk.

Re: Flex PL9

Having looked at it a little, I suspect there are enough PL9 compiler / environment sources in those archives to be able to build a Dragon / CoCo-ised version of 4.2D. But simply tracking down a Flex disk with them on would be easier!

Re: Flex PL9

Yeah, really hoping to turn up either the Compusense sold Dragon version, or the Universal Data Research Inc corresponding CoCo one. They will no doubt have some hacks in place to deal with 'the vector problem'...

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...

Re: DIY-Project for USB/SD/Floppy connection

Hi Snocksman.

There are a few options.

This is a nice one for self build...

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.
