A1230/50 SCSI Problem
4 messages in this thread
Like others, I've been having SCSI problems with the GVP A1230/50+A1291
combination. When I bought the units they wouldn't work at all with a Conner
CP30080. Through GVP Tech Support the A1230/50 was RMA'd to GVP for a "resistor
modification" which was to compensate for a changed clock line in recent
A1200s. Since then (March) I have been able to use the SCSI, but only
intermittantly.
When the A1200/1230/1291 is first turned on, everthing works fine. After 1/2
to an hour the Amiga starts to hang on SCSI access. The longer it is on, the
more likely it will hang, until it locks up on every SCSI access
If it is left off for a while, it will return to normal, until it warmes up
again. Seems to be temperature related. Please advise what I should do to get
this resolved.
Cliff,
Obviously the resistor modification had some affect on the system performance.
Try leaving the bottom cover plate off on the A1200. I have seen some
instances where the CPU chip is grounding on the keyboard. This was the main
reason for the replacement cover. Also, see if you can isolate where the
system is overheating. This may give us a clue and allow us to resolve the
issue without having you send the unit in.

GVP Tech,
Yes, removing the bottom plate helped. Now I'm getting about 3 hours of use
before hanging, instead of one hour.
As to where the system is overheating, the only thing I can determine is
that the A1200 feels warmest approximately between the F7 and F10 keys, toward
the back. In other words, the center of the rear half of the top surface.
Thanks for your help and I am looking forward to your additional
suggestions.

GVP Tech,
Removing the bottom plate helped. Now I get about 3 hours of use before
hanging, compared to about an hour with the plate installed.
As to where the A1200 is overheating, I can only determine that the top
surface feels warmest in the area between keys F7-F10 and the back.
Thanks for you help and I am looking forward to your additional suggestions.
