@Icky , very nice. :excited:

I get the impression I may have forgotten to add blitter support into the firmware :lol:

So back to the HD appearing (or not) in GEM TOS206.... https://www.exxosforum.co.uk/forum/viewt ... 18&p=31160

I am decoding ADDR:[FF9200..FF9201] as mentioned by @thorsten.otto and setting bit 14 low on that address, but I still do not get the format option up.. BUT, I have had odd issues with that bit on my board, it meters out, so this may have to wait until I can get a second board built to try out.

V6 is slowly getting there. I have managed to get all the components on and routing is just now around the PLD with about three quarters of the PLD to finish fettling in.

I have managed to catch a cold today so I spent most of the day on the sofa fettling in the routes and am now down to a quarter left around the PLD. Hoping to finish this off this weekend if the cold does not turn into man-flu.

Now down to 6 routes to go. It's getting very tight on this little board.

So just to remind me, flash, clock and tt ram all in one board?

Sounding great so far.

@PhilC. Yep - 4x Banks for ROM with ability to use mother-board ROM as well, RTC Clock & ALT-RAM all in one board.

Should be a great board when it's all up and running.

@Icky hope you feel better soon.

@PhilC the current v3 has the option for alt-ram, just I been waiting ages for my boards to be built :(

That board is 8MB 5v and will also fit the sec booster boards ultimately, So will give 50mhz ram.

Icky is working on v6 which is all 3v stuff. So he has gotta mash on loads of IO converters in, and I also found a single 3v SRAM chip which is also being mashed onto the board. I gave icky a near impossible challenge to route it all in such a small space. I think it would end up being 6 layers, but icky is trying to keep it to 4. Its a very difficult board to route though. In particular as I keep adding stuff to the design :)

Will this break icky ? Tune in for next weeks exciting episode :lol:
