It's worth checking the 5 Volt DC rail too. If the 5V supply is low, or fluctuating, it will crash the machine. And then it will automatically reboot once the supply is back above a certain voltage.
You can measure the 5V voltage from a few places, one place that comes to mind is across the 2 pins of P6 on the CPU board - unplug the connector there and measure the pins (P6 only powers the inverter/backlight so you can safely disconnect it). Any measurement under 4.7V would be a cause for concern, also if the voltage is not very stable and fluctuates, the power supply is a possible cause. Other causes of this low power could be some faulty device draining too much power.
- What drive are you using, a CF drive?
- Does your 3000 freeze so that you always have to physically switch it off/on again, or does it reboot itself?
GREAT INFO!
ill try this tomorrow.
the voltage drop makes sense.
for the moment I did an Internal SCSI mod, chaining another 50 pin adapter port inside the machine with a two connector cable... and leaving the back port installed.
The ZIP has been having read errors, and the click of death syndrome is starting, but I haven't been using. because of this. the power surely will peak sometimes if the drive is sketchy... I think I will try nothing in the scsi chain and nothing using the power connector... see if anything happens.
it has always happened while making a beat, never when I was saving or loading. this always had me thinking it was board related somewhere, but if the vibration made the SCSI drive draw a power surge? maybe that's it.
the 5v rail is the same 5v on the screen power as on the "device" or floppy power?
thanks
