Re: WIP Atari ST ScummVM-lite

In my H4 under TOS 1.04 or EmuTOS, I seem to have no sound (music or talking) now in DOTT for the last couple of releases. Indy, MI2 and MI1 are all fine for sound and talking. Latest version seems to fix the speech cut-off in MI1 and Mi2 now. :D MI1 still has the splash title mixing with the drifti...

Re: kodak80 blog

I had a stash of Fujitsu MBM27C1000A 1mbit UV EPROMs I purchased a while ago and found that my TL866II programmer did not have listed. Rather than throw them away as no one wanted to buy them from me, I held onto them. I decided that I wanted to try using these in my STE instead of the usual 27C010 ...

Re: Atari 520STFM bombs on boot

Hi Bartek First easy thing to try is remove and re-insert any chips that are in sockets. Cleaning the chip pins may also help. Have you replaced the capacitors on the PSU? This is one of the first things that can cause strange issues on the Atari. As you say you have 4mb RAM, what add-in do you have...

Re: H4 16mhz modification

Spent some time today looking at starting this on one of my H4 boards. I have built one the 16mhz mod boards and tested the clock output on this is as expected with the 32mhz OSC on the mod board. https://www.exxoshost.co.uk/forum/download/file.php?id=6796 First thing I have found is that the jumper...

STM1 mouse IR LED replacements

Just wondering if anyone has the part numbers or specifications of the IR sender LEDs and IR receiver LEDs used in the STM1 mice for the ball directional wheels?

I have a number of these mice which I would like to see if replacing the LEDs will fix issues withe the directional movement.

Re: kodak80 blog

:goodpost: :bravo: Nice work! I'm still trying to find/make time to diagnose the faults on a few STFM boards so seeing these posts of positive results is very encouraging. When I get round to ordering some PCB's I'll have to make sure to include some of your design in the order (if that's OK with y...

Re: kodak80 blog

As I have now tested these work. This is the Gerber for the 32 pin 27C010 adapter boards I used from my STFM 2 chip TOS. For anyone looking to get some made. Just keep in mind that sockets in the top of this make it sit too high for shielding to be fitted. It might work if soldered directly to the m...

Re: kodak80 blog

I recently purchased a 520 STFM board from the UK and when it arrived, it was showing 11 bombs on boot with some corrupted graphic artifacts on the screen. The board is the same model and revision (C070789-001 REV F2) as the one I was testing the 2 chip adapter boards in. All ICs on this board are s...

Re: kodak80 blog

My PCBway order finally arrived and included these 32 pin to 28 pin ROM boards: IMG_4918.jpg I built a couple up and tested them with 27C010 chips with TOS 1.04 with IDE patch programmed in and tested them in one of my 2 chip STFMs: IMG_4920s.JPG These were so that I can test the programmed chips wo...
