I managed to obtain this is somewhat broken state but managed to fix it :)

I connected it to the 16MHz line using the free wire on the board, and this seemed to work fine. Going by the chips would seem it has a cache on board. Some assuming this is a early design, or even a prototypes ones which have the oscillator on board which will run at 28MHz normally..

TEST RESULTS:
Just for comparison a normal 16MHz boost on CPU only..
Results from 16MHz CPU & ROM
So the cache is to add on average 24% speed boost.. Not too shabby I guess...

I would love to get my hands on the jed files for the 2 gal chip. My T16 is dead, blown gal

I should run up GB on my MSTE, see what the results are @ 8Mhz, 16Mhz - cache off and 16 Mhz - cache on. I can get a comparison result from one of my standard STEs.

Just in general desktop usage, 16Mhz cache on feels quite snappy and a cut above standard ST.

Would you be willing to sell your dead t16?
