Tacho Universal PCB DUMP, HEX collection green, blue, red for sync & reset problem


Hello together,

my Tacho universal with the blue pcb and blue screen has the typical Sync problem.
I've read many threads and tried different dumps which were postet in this forum. Nevertheless all testet dumps (all shared for green pcb) do not work for me.

I would like to post now this thread as a kind of cluster of information - or lets say dump collection.

It would be nice if someone with working Tacho Universal can post his/her dumps here for its pcb colour with full WORKING DUMP content. It would be great to get a dump collection in this thread for all pcb colours green, blue and red with following eprom dumps:

Green PCB
1. IC111
2. IC112
3. AT24C02
4. PIC12F629
5. 74HC541

Blue PCB
1. IC111
2. IC112
3. AT24C02
4. PIC12F629
5. 74HC541

Red PCB
1. IC111
2. IC112
3. AT24C02
4. PIC12F629
5. 74HC541


Writing of dumps in eproms should be done with an programmer.
(If you do not have an eprom programmer, get one or order the repair kit with all eproms included for about 50$. Nevertheless I've heard that this kits somethimes work, sometimes dont work.)

Eprom installation should be done like shown in attached "TURepair&UpdateManual.pdf"

If not installed, crystal oscillator should be for all pcb:
12 000000
Kony 0615

Please no discussion or questions in this thread - this is just a dump collection! Hope this post can help everyone who has sync, reset, update or dark screen problem like me.
