Re: TF536 EmuTOS and TOS2.06

...When i look at EmuTOS download i see versions 192, 256 and 512. And from what i have gathered they are suitable for different branches of atari. For Atari ST it is the 192 thats most suitable?... Easiest to explain is that in Mega/Standard ST(f,m) they have a TOS that is only 192Kb large. STe an...

Re: Small/thin shielded cable?

Try to twist some of the same size around the clock wire and ground them.

EDIT: fine enamelled wire perhaps. Then heat shrink tubes around all if you want.

EDIT2: Those small thin antenna wires that are in mobiles ought to be shielded. I don't know what they use or how they look inside though.

Re: Random STuff

Finally soldered up the 8Mb attachment board for the ST Ram in the TT. Didn't work the first time. Thought it needed beefier VCC and GND so tried that and also found that I had forgotten to solder 1 pin. So test was with the thick cables in place but that was removed later on since it wasn't needed....

Re: kodak80 blog

Really nice project with the MT32. Got inspired so I have order all the parts for a MIDI PiHat. Going to use it on a Pi3 A+. Seems pretty straight forward.

Re: Robson's H5 x 2

Do you only run with 1Mb or is the diag reporting it wrong?

Re: DoG's H5 B1 Build

I did a recap on another PSU but I remember that that one got hooked up to some large resistors and got adjusted when I first turned it on. I think it was used for the H4.

Re: DoG's H5 B1 Build

The recapped PSU I have been using (for over 1,5 years) put out 5.5V and that is not fine for the H5. Odd.. But yeah 5.5V is a bit high anyway. Is your 70859 board using 2.2K bus resistors or the original ones ? Hmm. I think I have changed them. But not 2.2K. It think it got 3.3K on address- and 4....
