I would rather doubt a MMU chip problem.  It is MUCH more likely
that you are seeing ringing and other noise problems.  A good way
to check for this is to run a decent memory tester program when
the board is set up for 4MB, and see where it gets errors, and what
the patterns of error bits are.  If you get randomness, it is almost
definitely ringing or other noise problems on the dram control lines.
 
One example to show this... Recently I upgraded a Rev. E 520 ST
board to 4 megabytes using the "New World" board.  Initially it showed
exactly the same symptoms you got; it worked fine at 2.5megabytes,
but got memory errors at 4megabytes.  I eventually got it to work
at 4 megabytes by shortening 3 of the interconnecting cables to
about the minimum workable length (about 9 inches -> 6 inches),
added inline 68 ohm resistors to the RAS/CAS lines for the upper
bank, and an inline 33 ohm resistor to the MAD9 line from the MMU.

You guys are amazing (for lack of a better word), Dave and Jim hold a
CO to judge the market for their *proposed* new ST product and already
its vaporware!!  Some of you needs HEAVY doses of valium my friends!

Subject: Hard copy on a 24 dots printer
 
I wrote a printout program for my Panasonic KXP1124 (no guarantee of
compatibility with other printers). It accepts either DEGAS or TINY
format files of black and white screens only, and it doesn't replace
the alt-help command because I couldn't figure out how to do that.
Instead I use Braner's BARREL to grab screens and store them as DEGAS
files, which is crude and wastes storage space. If I want to keep stuff
long term I translate it to TINY.
 
The printout is either 1, 2 or 3 dots per screen pixel; the last prints
sideways on the paper and almost exactly fills a sheet, while at 1 dot
per pixel the printout is less than 4 inches across.

I am looking for any civil engineering oriented application for the Atari
1040STF. How about STRUDL for instance? Any suggestions to the following

Thanx.

Subject: Noisy 1040st??!!
 
    My 1040st buzzes.   It's not the monitor, it definitly comes from the
machine itself.  It's a real highpitched whiney buzz that seems to come
from somewhere on the left side.  What's more, the pitch of the buzz varies
with whatever is going on on the screen, e.g. a higher pitch with a white
background and lower pitch with a black background.
 
   Has anyone else ever heard of this, or is this completely normal and
am I making a noodle out of myself?  I know someone with a 520st and it
is completely quiet.
 
   It's getting quite irritating.  Please email me any information that
any of you might have.   Thanks.

Yes, I'm sure there would be interest in a good shareware MAC emulator..
 
But Dave Small has established the standards here for what a MAC emulator
should do, and how it should perform...
 
(Playing "Devil's Advocate",) do you think you can compete with the Spectre
Mac emulator..?

Hello Graham,
 
thank you for your message on GDOS. It really shouldn't be that
mysterious, as i've learned from the mails i received. But there
is still a lack of DETAILED knowledge on my side. So could you
please send me the file you mentioned? Nobody else offered any
documentation of this kind.
 
Nice to hear that you know Stuttgart! I guess the punch card time
is over even at Hohenheim, but Hohenheim is still a nice place.
I ran my first FORTRAN programs also from punch card in the late
1970's, not in Hohenheim, but in Stuttgart-Vaihingen. A lot of
friends lived in Hohenheim then, most of them studying Biology.
 
Best wishes,
 
             Benno

RE: DataFree 2/4 meg mem board
    Help! Datafree's instructions don't match the ground truth in a REV C
1040. Specific problems:
   1. mmu and video shifter chips designations seems wrong.....not major,
      but I need to lift some resistors to disable 1 bank of mem, Datafree
calls for R93 and R94, which I can't find, and I suspect their numbers for
these are whacko as well.
    2. the little baby board that should plug into the video shifter's socket
      hits two transistors (Q4 &Q6) and won't go securely into the socket. It
will clear these guys if I rotate the baby 180 degrees but that seems counter
the orientation shown in the instructions.
 
    Added features..my version has what I think is the video shifter in a
rf shield and is labeled U49 w/ C070789-001 on the chip itself. If this is
not the correct chip, problem 2 above is cleared...these is another chip
of the same size close by, in the open labeled U15 C025913-38.
 
    Any help given/mercy shown much appreciated. Thanks!  j harris fairbanks/ak
