Utilities

More stuff recovered from backup tapes: Epson Graphics Dump and Printer Control don't appear to be in the archive. Maths CSE Revision is a fully working capture. The one in the archive seems to be incomplete. Anyone remember SuperBasic? The publisher doesn't ring any bells for me. Perhaps it was sol...

Re: Dragon User Programs

I think I typed in a later hi-res thing called 64-COL Ah yes, I remember that. (Dec 1987). I typed in a lot of stuff but I've no idea what happened to it all. Perhaps one day when I'm too old to come up with new stuff I'll have a go at OCR'ing some old favourites. btw I should have said thanks for ...

Dragon User Programs

Found an old box of tapes in the loft with some programs I typed in from Dragon User when I was a kid.

Re: Serial Numbers

Forgive me if I've missed the point of collecting serial numbers, but found the ones below currently on ebay. Posting images from ebay is probably a no-no but these are the numbers (all d32): Swansea 033793 DG 057402 DG Port Talbot 080799 DG 103566 DG 158756 DG 166689 DG 237196 DG 249677 DG 253680 D...

Re: Project 2

Your demos never get old. Every aspect is done to such a high standard that it's a pleasure to see.

If you're looking for a more critical opinion, my eleven year old says your game looks cool. And this is from someone who is obsessed with playing Terraria and Mindustry online with his friends :)

Re: Does Mr Dig work properly?

Cuthbert Dragon did a video a couple of months ago so it definitely does work on a D32.

I tried disk and tape 'play now' options in the archive and they seem to work ok.

Re: 6809/6809E compatibility

Hi Rob! In general the internal/external clock versions are not interchangeable so I am amazed it works at all. As you say, there are a number of pin differences but the ones that matter in the Dragon are the E and Q directions. So in your D64 you have both SAM and CPU trying to drive the E and Q cl...

Re: DRAM data retention time

A Z7 invert option is a great idea. I wish it would fit but unfortunately the GAL only has one spare I/O, and that would get used up just by adding the register. I wonder if any OS support was produced for the original banker board? There was no mention of it in the Hot CoCo article. Edit: Drivers w...
