    Can anyone shed some light preparing a Mega2 ST that has six ROM
sockets for use with the T16 and upgrading the Mega2's memory to four meg?
    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.
