hmmm, I do not like the idea of overheating an already old and delicate (not to mention rare/expensive) system. I'll have to seriously consider whether this mod is worth the potential accelerated aging of the CPU by the increased electronic strain of unaturally high frequency rate :/
but beside that, does anyone have any specific info. on this particular mod? I cannot seem to find any driver s/w for it on any of the disks i have been given and I'm not even sure if it is active, pretty hard to tell....any good Atari system diagnostic s/w to test frequency rates??
