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..

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...

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)

I will do my tests with a Lattice CPLD, where I have all tools (compiler, programmer) available. Unfortunately not pin compatible, so it will need some extra wiring.. I can send you a PCB.. but I think trying to force wire a different PLD would require much more effort than just creating a new PCB ...

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

Also, what floppy drive are you using exactly ? and have you tried a different one ?

Also when it bombs, what happens if you press reset on the back of the ST, does it bomb again ?
