Help -- CD32+SX32 Pro crashes/unstable
Troy Pladson
Hello, all!
I wonder if there is anyone here who has a CD32 and purchased an SX32 Pro
expander for it. I have, and have been having problems with the system
being unstable and crashing after it's been powered on for about an hour.
This is the complete system set up: CD32, SX32 Pro unit with 50 MHz 68030,
and 50 MHz 68882. Toshiba 1.44G 2.5" hard disk, external 880K floppy, 200W
power supply, 16 meg SIMM, A4000 keyboard, C= 1960 monitor.
The system runs perfectly for about an hour, then becomes unstable. An
example of what I mean is, I can use LhA to test the integrity of an
archive upon a cold boot, and the file tests perfectly. After about an
hour, I perform the same test, and get messages of the file being corrupt.
At this point, most software will still run, but is prone to eventually
crash the system. If I were to just leave the system on, with the screen
saver running (just C='s "Blanker" for now), the system will run and run and
run, without any problems at all.
I have tested the system with two different 16M SIMMs, but get the same
result. I have checked power connections and tested the PSU with an ohm
meter (just voltage levels), and it seems to be good.
Does anybody have any idea what is going on? If you do, please help. I put
a lot of money into getting this system going, and now this. Any help is
sincerely appreciated.

Troy, It sounds like your CPU (030) could be getting a bit hot in
there, Is there space for a small PeeCee (yuck) fan anywhere? It might
involve a little bit of a case-mod' to keep the 030 from heating up
too much, your HD beside the CPU could also be involved, if you can
cool the area of both of these, It might help things.

This sounds very much like an overheating problem. Try cooling the
system by using a fan and see if it helps.

How would a fan be installed in the CD32? There seems to be little

It works great but I think that I need a fan also. Thanks

The SX32 pro is the unit that fits completely internally isn't it? Perhaps it
could be a heat problem. I heard that when these boards are installed by the
parent company (Eyetech?) a fan is added to the case somewhere for cooling.

Perhaps try to aim an external fan on the unit and see if that helps. That is
ALOT of electronics packed into a pretty small case :-). Sounds like a really
nice setup, I hope you get it going well.

With all that stuff in there I think you should install it in a nice
mini-tower case..........You'd definetly solve heating problems that way,
and it would be alot more asthetically pleaseing..........

the crashing problems. What I did notice when I got it from Eyetech
was that the Main board was coming adrift from the backplane,
regardless of the note in the installation notes about it having to be
put together with a special tool. It could be that as the circuit
board warms up and expands, the connections are coming adrift.
Mine gets very hot on top, but I've regularly left it on for 4 - 5
hours at a time and have surfed the net for 3 hours or more with no
problem.

The problem could be electromagnetic interference since the SX32-Pro is
not shielded in any way. It might be your Monitor or something else next
to your computer ( or something in greater distance).
It is also possible that the power-supply breaks down only for a very
short time, e.g. while accsessing your Harddrive or Floppydisk or CD-Rom
drive. This short period of time is to short to be recogniced by a simple
multimeter. You would need a oszilloscope with memory capability or
something similar to detect this.
Or it might be an incompatible Virus ...
P.S.: I'm not shure wheater your repeated message is the complete one you
posted.

Well, I have almost the same setup. I have the same HD, also 16 MB Fasr RAM
a bigger power supply and a external HD-Floppy from DELL (same colour as
the CD32).
I do not think that it is a heating problem. My machine does not becomes not
very hot. I do not have this kind of problems. But I have another one!
When I bootet my machine (from HD or from Disk) and then insert a CD the
system crashes. Sometimes I get a Guru and sometimes the machine looks like
it reboots.
So can anybody help, or does anybody know a solution?
Troy, what kink of CD-device do you use?
I am also interested to connect a SCSI-board to my CD32 (for a ZIP-Drive).
I heared something about Dataflyer. Has anybody tested? Where can I get it
and how much does it cost?
Thanks in advance

Just a note on this same thread the instructions with my unit specifically said
it was only good upto 8 megs of Fast RAM. It makes no sense but neither I nor
Gary are using more than 8MB fast while the original poster says he is using
16MB. IF that's not the issue my next guess would be an overclocked or failing
FPU or CPU. Try different ones and see if your symptoms change.

Well...No. The English 'manuals' that ship with the SX32Pro are actually
two parts. One is the original manual for the SX32 Mk II (which did not
have the '030 processor). That board was limited to 8MB. If you read the
SX32Pro 'addendum' it states that since the boards are very similar, only
the items particular to the Pro were included. The Pro should be able to
handle upto a 64MB SIMM. I have 32MB SIMM in my Pro right now. The 8MB
limit has a lot to do with the 68020 (and C='s design) on the CD-32
motherboard. With the '030 you should have no problems with larger amounts
of RAM.
One thing that hasn't been mentioned is the power supply. We all know how
low powered the stock ones are, so I wonder it the original posters
problems are not coming from it?

Recently I bought a new "light weight" psu , supposedly like the
A1200 (25W) but on checking the electrical safety (OK, looking
inside) I noticed that there are two size options for the switcher
transformer, and this was the small one (17W)
It did not cure the crashes, but, thanks to the CD32 FAQs, linking
out the relevant contacts of the CD32 ON/OFF switch did ;^)
After the fix, even adding a test load to the +5V of an extra 5W
did not crash the machine. So I now have two working PSUs, one
heavy (linear) one light (switcher) but both 17W, enough...
Moral; remember to read the FAQs ;^)
