I've been reading conflicting data about what brand and speed memory chips to use if one wants to use the T16. I've also been reading that the T16 is happier if used with fast ROM, that is, copying the original TOS 1.4 EPROM into faster EPROM chips. Also, should the older 'Atari' blitter be replaced with the newer? Incidentally, the 74LS373 chips have been replaced. I had problems with Spectre until they were. SIGH...this is a terribly worded letter. Basically, I'm only asking: 1. What memory chips should be used for upgrading the ST2 to a ST4 if used with the T16? 2. Should the chipped TOS 1.4 be transferred to fast EPROMS to gain maximum results from the T16? 3. Should the Atari blitter be replaced with the newer? 4. Yes, the 74LS373 chips have been replaced.
