Re: Future PSU designs

All the ST versions I am doing are now in stock. https://www.exxoshost.co.uk/atari/last/storenew/#0030 I am building up the remaining ones today with the Falcon power connector on them. These will be green PCBS (not red like the ST ones) But it's the same PSU design as the red ones. I will be supply...

Re: STFM Booster 2.3 + Dual TOS Kit, TOS 2.06 Issue

No, TOS206 never worked (not with 16MHz and also not with 8MHz -> same behaviour) Ah ok, that makes a lot more sense then.. I thought you had it running with TOS206 at 8MHz... Should I run something or just the desktop? Its probably not worth it I think now... 16MHz is working with TOS104, so eithe...

Re: STFM Booster 2.3 + Dual TOS Kit, TOS 2.06 Issue

Very strange...

I don't see how TOS104 works at 16MHz but not TOS206. Its like TOS206 ROM is corrupted, but you said it works at 8MHz ?

Can you boot TOS104 and run GB6 for a couple hours and see if TOS104 is stable at 16MHz..

So about 15% speed boost going by those tests for RAM speed.

DDR3 1600MHz Vs 2400MHz

My PC has been running 1600MHz DDR3 CL9 (HyperX) for several years. Though I spent a long time hunting down the fastest DDR3 I could find which would work in my motherboard. I managed to find some G.Skill Trident which is CL9 at 2400MHz. The problem with RAM speeds is the CL increases with the MHz. ...

Re: STFM Booster 2.3 + Dual TOS Kit, TOS 2.06 Issue

Thanks.. It looks like the yellow line is the booster pin 1 ? The signal doesn't look as good as it should be. I suggest you put a 68R in series with the wire going to pin 39 of the shifter... try again... if still problems, add another 68 and try again... Also have you tried a different floppy driv...
