Dom;
I believe that the 030 is a bit faster than the 020 with many instructions.
The cache is larger so loops that will fit in the cache will run much
faster. The 882 is also quicker than the 881. The 551 doesn't matter
since AmigaDOS is not using the MMU anyway. For most uses, I doubt that
you would notice much different between what you have and an 030 clocked at
the same speed.
Yes, if you wanted to go beyond the memory on the 020 board you would have
to buy and additional memory board. I suspect that you would have to buy
an 8 meg board since I have not heard of a 4 meg version. Also, your
numbers do not seem right….. I would expect to see the 020 board support
2 or 4 meg for a system total of 3 or 5 (without additional memory boards).
The additional board would definately be much slower than the memory on the
32 bit bus.
I am surprised that you got a 2090A (of course I am surprised that you got
an 020 accellerator too). The HD is NOT attached to the card on the 2091
though there is room. You can mount the Rodime in the 5 1/4 bay using an
adapter. I used a Rodime drive for several years. Shipped it across the
country and it stopped working. Suspected rough handling but could not
prove anything. Rodime has been in the drive business for many years and
makes a good drive.
No, monitor cables and pin outs are not standard. The Flicker Fixer port
connection does match one of the IBM Video Port "standards" but you need to
be careful. My Flicker Fixer manual states that the cable supplied with
the monitor should NOT be used for all of the monitor listed except the NEC
Multisync II. Redmond Cable can supply the correct cables (don't have
their address but ask since many others do have it).
