Robert, funny about screen not working for you. I just set up a couple of
|
|
screens and got basic running in both. Loaded some programs and did a dir and
|
|
all worked just fine.

To: all

I got one of the MM/1 68340 accelerator boards at the
|
|
Atlanta 'Fest. Zack Sessions has already posted an
|
|
excellent technical description and review of the upgrade,
|
|
but I thought I would add a couple notes on my own
|
|
experience with the faster system - and a couple more
|
|
"gotcha"s.
|
|
|
|
I did not have the "slow" PAL chips on my I/O board, but
|
|
just when I thought I was safe, I discovered some on the
|
|
8-meg memory board. Replacing them was not as hard as I
|
|
thought it would be, but not a job for someone without
|
|
experience in repairing electronics. Like a famous coach
|
|
said about passing is a football game -- "Three things can
|
|
happen - two of them are BAD".
|
|
|
|
It is, of course, FASTER. Thats why we bought it. The
|
|
TeX and PostScript (and Ghostscript) programs I have been
|
|
playing with lately take a lot of time. Building a new font
|
|
for TeX ran about 15 minutes before, now its about 7. I
|
|
don't have a "dhrystone" program (or even a whetstone), but
|
|
I can easily see the increase in speed. I did run the
|
|
little basic "benchmark" program that Frank Hogg posted some
|
|
time ago, and the 68340 came in right about where you would
|
|
expect it.

It boots from the hard drive. Twice it has stumbled a
|
|
little on a cold start when it looked for the drive before
|
|
it was up to speed, but it got it on the second try. Both
|
|
of my hard drives, a 40 meg conner and a 40 meg quantum work
|
|
fine as "/dd".
|
|
|
|
Zack said he got a new "shell" -- I didn't. I have the
|
|
same shell I had before. Also, "dEd" runs fine - but that
|
|
is probably because of the different shell. I asked Kevin
|
|
Pease about that new "shell" - he said he didn't know where
|
|
that came from. Apparently Zack got an accidental "gift"
|
|
from somewhere.
|
|
|
|
Windows have a little quirk - changing colors on one
|
|
window does it to all of them. Kevin Pease has a fix,
|
|
provided by a well known OS9 Guru - he said he would upload
|
|
it very soon.
|
|
|
|
I have heard of problems with MM/1's talking to
|
|
printers, especially with long cables, but I was getting
|
|
away with it up to now. I had ribbon cables from the MM/1
|
|
and a big ugly "386" running to switch boxes, and parallel
|
|
cables from the boxes to the Epson and the Deskjet so I
|
|
could switch either printer to either computer. --- No
|
|
more. With the faster CPU, the MM/1 wants a short cable
|
|
directly to the printer. (I can live with it).
|
|
|
|
The reason I haven't said a lot in the forum about my
|
|
new toy is that it had this little problem -- every once in
|
|
a while, especially after a cold start, it would trash the
|
|
hard drive. It seems there was this little timing problem
|
|
that required some attention from Kevin Pease. The good
|
|
news here is the response I got on the problem. I bought
|
|
the upgrade at the "Blackhawk" booth in Atlanta, which was
|
|
manned by Bill Whitman (another IMS rep). When I decided
|
|
something was wrong, I called Bill (put a message on his
|
|
machine), and left CIS email for Kevin Pease. BOTH of them
|
|
called me at home within a day. Both had suggestions and I
|
|
tried them all - but finally had to send the insides of my
|
|
machine to Kevin. He tracked down the problem, made a new
|
|
PAL to correct it, called to let me know he had it fixed,
|
|
sent it back, and called me again today, just to make sure I
|
|
had it running OK.
|
|
|
|
As Delphi and CIS OS9 forum regulars know, response from
|
|
IMS has, in the past, been.. well... less than
|
|
outstanding. Paul Ward has not appeared on CIS or Delphi
|
|
for many moons. ((I think Frank Hogg ran him off. Frank
|
|
was mean to him. Look ashamed, Frank.))(GRIN)
|
|
|
|
David Graham (Blackhawk) (NIMITZ) has obviously been
|
|
trying to correct the situation. Although he was not at the
|
|
Atlanta 'fest himself, David left his booth in good hands.
|
|
I am very pleased with the 68340 and the quick technical
|
|
support.
|
|
|
|
Like Zack, I feel my money was well spent. Get one.
|
|
Check with David Graham (NIMITZ) for current price and
|
|
delivery time.

Hmm, was that U18 on the IO board by any chance? Reason I ask was that I
|
|
received just today, a replacement PAL for U18, from Bill Wittman. He states in
|
|
his letter that "on some systems, not many" require the new PAL to help solve
|
|
"hard drive problems". Even though I am not having hard drive problems (unless
|
|
you consider not being able to boot from the hard drive as a "problem"), "Pease
|
|
highly recommends that you put it in".
|
|
|
|
And I concur, support from Kevin Pease and Carl Kreider has been excellent.
