634 v1 dead


New member

A student of mine(really!) accidentaly dropped a 240VAC line onto a microcontroller circuit that was connected to a 634 v1 display.
This ofcourse, blasted the microcircuit, and also caused the display to start to behave erratically, and finally it got all dead.
I am hoping that it's only the Holtek microcontroller on the backside of the display, that has failed, as this is easy to replace.
How ,or where, do I get the program (hex file I assume) that goes into it?

Anyone tried this before?

Mmmmm smoke. That is what makes the lab interesting.

We cannot give you the code for the microcontroller, but we can probably help you out.

Handling in a support ticket.

I'm ordering some new displays tomorrow. - if helping me out means supplying programmed Holtek chips, could theese shipments be combined? (save shipping costs...)
