Peschges VP3 Problems

[Nick Gilbert]

Hi There,

I have a VP3E that is giving nonsense characters on startup. Have flicked
all switches to no avail. Anyone seen this before? Is there anyone left that
can service Peschges stuff?

Nick.

Hi,

Could this be a problem with the LCD display contacts? Try cleaning the
rubbers, ours had a lot of dust etc. in between the glass and the rubber
contacts. You could perhaps also _very gently_ try to press the display
edges and see if it helps to get a proper contact...

I had this problem earlier this year - it turned out to be caused by a
faulty connection in the wiring to the battery.

The problem took ages to diagnose (because I thought the VP3 had just died
of old age or had something wrong internally and so didn't test the
circuitry). I finally discovered the problem because the connection
deteriorated so far that the radio stopped working.

This one is quick and cheap to check, so I'd try it early on.

Just an update.

The wiring & the screen appear to be fine. I completely dissassembled the
unit and found 2 watch type batteries, both dead flat, and both the original
batteries in a 12 year old instrument. 5 years seems to be their useful
life. I have a feeling that as a result the eproms contain no data!

Thanks for your help.

Nick.

So these things are not eproms!

They may be battery backed static RAM but I think the program was in
EPROM in the Peschges instruments. The RAM probably holds data while
the program is running and the batteries provide memory retention in
the evnet of a ship's power interruption.

If the EPROMS are damaged you could always copy ones from another VP3.

Thanks Mike. In the event that I get it working, is it any better than one
of your old b24-b25 systems?
