Ah, so this is where all the fun is happening! That's awesome :) I could be wrong but I think the majority of 256K drams had 8 bit refresh. Yeah I spotted that but it’s almost no extra to do 9. I'm curious to know if the logic to recreate the glitching is using up much resource or if you can get so...

Getting there. Still a slight wobble

99... and yeah that's with the banker board registers and 9-bit refresh (overkill, i know, but you only save one cell cutting it down to 8)

Meh. My glitching is glitching:

Macrocell usage down to 111 though (98 with compact FSM!) as I realised I was being dumb with a few things.

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. Afraid to say it ends up using more somehow ;) Of course if you were going to take this and use it for a more modern recreation, you'd rip out...

Edit: it's released now :) I'll post this here too... Working on a SAM replacement - not as a product really, more to prove the concept and work out the bugs so it can be used in future designs. At first I thought the reset detection wasn't working, but after bodging around that I put things back as...

Here you go.

It's the Tano Masterpack, and I have it down as being "by" "Tano Corporation", though I think a lot of it was by the Programmer's Guild.

I'm sure I've uploaded it here before...

I have a DH.

What I can’t tell you is - other than it’s a Dragon 64 - what revision of motherboard/PSU was originally in it. Swapped things around too often.

Rick Uland's been working on "CoCoIO". I don't know much more about it than that - in particular, I'm not even sure if this is CoCo 3 specific. If it's supposed to work on the CoCo 1/2 as well, then hardware-wise it'll doubtless be fine on the Dragon too. Definitely ask first! And you'll have to be ...

... and indeed the whole disk may be more SuperDOS-specific - now I come to try it, the BOOT sectors don't seem to work under DOSplus, where the archive copy is ok. So maybe just consider this a curiosity
