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. Cart Adapter-routed_2022-09-08.zip Cartridge slot fits flush with the external ATX case so will not allow cartridges in cases to be fitted. I am working...

I am now on my third working board. The third one has the SILs in headers so I can test the CPU expander and test PC-Speed etc. I am currently using the original SIL resistors in the BOM for the ATX board.

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. :D

Still need to test MIDI IN port so planning to fire up MIDIMAZE 2 tomorrow with the 2 boards.

Re: kodak80 blog

I now have 2 fully built ATX boards here, a third board will be heading down to atari030 for him to build up. The PIC chips arrived and I got the keyboard, mouse and joystick running now which is allowing me to format the CF IDE hard disk connected to the IDE connector. Power for IDE CF card adapter...
