   Today's lesson, grasshopper, is "bandwidth". Lisa can do a 64-bit fetch
during a single Chip RAM bus cycle. Denise could do 16-bits/cycle. (Correct me
if I'm wrong Dave, I'm going on memory here.) The bandwidth moves more data
in a single cycle than it used to - it's not being crammed down a 16-bit bus
faster. Remember: "Bandwidth".

   Bzt. I'm sure I can say with some degree of accuracy that most Amiga games
are still no better than 32 color. There do seem to be more EHB games coming
out now, but the lesser color games still appear to outweight the EHB ones.
(For instance, the only Dynamix games that support EHB are A10 1.5 and Nova 9.
Those came out within the last four months. And I worked on both of them in
case you want to debate me on them.)

 Yet the chip RAM has been

   I could live with 2MB Chip RAM. But Marc, keep in mind that the original
chipset had reserved two megs of memory for Chip RAM - even in 1985 they knew
that 512k might not be enough. Don't you think Commodore foresees a day when
2MB won't be enough? Did you ask anyone about this before you flamed?
   As for 1.76MB disks, what do you want? It exceeds both the MS-DOS and Mac
high density disks by at least 300k. I expect next you will complain that they
are too slow for you - perhaps they're not "instantaneous" or something.

   Get 'em, Dave. (Someone sell Marc a BLAZEMONGER!)

   Then don't buy it. Just give us a break.
