Re: kodak80 blog
I tested the v1.1 of my ISA cart adapter yesterday and it works which is great considering I had to move from Eagle to KiCad for v1.1 due to the size of the PCB. It was too big when I moved the cartridge port outside the ATX casing and Eagle (free version) would not allow the size board needed. I ha...

Re: kodak80 blog
As shared on other forums. My ISA Cartridge adapter works fine with bodge wires from underneath the GLUE IC (pins 17 & 18) for ROM3 & ROM4. Looks good! What address lines are exposed on the ISA slot? No chance of doing the ROM3/4 decode yourself? Cheers, BW The required address lines for th...

Re: kodak80 blog
Hi @kodak80 I've finished my ATX board but have a number of issues with it that I've not worked out yet. I get bad ghosting on the display, Tos 2.06 fails the memory test after 8 dashes and the floppy doesn't work. I wondered if there was any fixes that need applying to a standard V1.1 board other ...

Re: kodak80 blog
I have 1 working ST ATX system at the moment but I am thinking that the pull-up resistors on it need to be changed on the next board I am building. The ST ATX system is currently using 10K/4.7K pull-up resistors and I note on the H4/H5 we used 2.2K/1K pull-up resistors. ST ATX BUS PULLL_UPS: Bus Pul...

Re: kodak80 blog
@kodak80 I was going to make some of those but you beat me to it :D Cool. I can also confirm that the VGA 16 pin header works fine. I tested it today. :D Still need to test parallel and serial headers. For the dual TOS, I am using 1.04 with IDE patch and 2.06. 1.04 boots the IDE CF card fine.

Re: kodak80 blog
For my ST ATX board which is now cased in a black Micro ATX case I have ordered these VGA to IDC boards to allow me to used a 16 pin ribbon cable to mount the VGA port somewhere.

Re: Atari ST ATX motherboard build project
Mine is now in a Micro ATX case. Very happy. SMD soldering the PCBs took me a good day or two to complete. Looking forward to seeing more ATX up and running.

Re: kodak80 blog
ATX board has now been tested with the latest cracked Cubase 3.10 playing MIDI files to my MT32-pi.
Still need to test MIDI IN port so planning to fire up MIDIMAZE 2 tomorrow with the 2 boards.
