With a new TOS decoder you will get more then 30% more Speed on the Rom access. I have measured on my TT 197% Rom Access with 16Mhz Bus. With the 48Mhz CPU its almost 230%. But yes with that little trick you can archive already a lot . Own address decoder means own CS and xds0 / XDS1 Signal.

Guus, when you load the TT default values, then you can compare to a stock TT with all Stock!

Wow that looks amazing :O well done...

Oh yes I see, but better to load the TT reference file!

AtarianComputing you have great schematics where did you got it ? Did someone a redraw

@guus could you please take a newer gem bench ? maybe that one from Exxos ? And without NVDI then you can see the huge differences

Create Partition on that USB drive, with partitions upto 512MB, before this go to compatibility and check Tos and Windows Compatible (no Byteswap).

Then the stick is usabel using TOS and Windows (Windows 10 supports more then one partition on USB Drives)

Please send an mail to thunderstorm@tuxie.de

I Say it from my experience site, did repair and boosted a lot of falcons. !!! So what should i say ?

The Volage isnt the problem, the Problem is the Timing , a F type 74F04 has 4ns per gate. Instead 20ns or so with LS or 7404. And when you put it through 2 gates then you have 20ns.

Its more an timing issue instead of Voltage!!
