the "police mode" is in VT-VX clusters & all it does is display the digital speedo, its no more accurate than normal

Thanks - I haven't seen the inside of a commodore for almost 15 years, so not really up to speed on these sort of things

programmer looks good festy, have you worked out why some numbers will display and others wont with the same checksum calc? I havn't had any luck

All going rather well actually
I got a bunch more done to the software on my train ride home, to the point where it's useable and generating complete (and valid) bins and dongle instructions.
I just need to add comm port and send the output there instead of printing it, but at even as it is now I can type in a odo number and program it in under 30 seconds, no more calculations and translations finally!


As a test, I picked a couple of the numbers you couldn't get going - 1529 and 1530 were two I think...

very nice work , i am wondering what im missing, sorry i haven't picked it up yet

For EG

1526 which didn't work before with this code
CC33 FF00 57A8 9B64

Works with this code
DC23 FF00 57A8 9B64

64^A8^00 = CC ^ FF = 33 So CC 33 which is how i did the ones that worked

Just trying to workout how to calculate word 0 properly.

Wow. You guys got really stuck into it. I think i might have a crack at this if yall whiling to give a hand. As fair as i can tell i need the $20 ebay reader and ponyprog to get started?

yeh that ebay programmer and you'll need to make up a custom socket to use the icsp header on the burner, the wiring for it is in that pdf a few pages back. If it's a once off and you dont want the hassle im sure one of us can organise a burn for you, but the programmer is cheap!

This is what i made up

Cheers mate. Ill grab that PDF and organize some parts and such. Thanks for the offer for a one off burn but i would like to learn how to do it. And the only way i learn is buy doing it. I have been reading this thread from day one, but half the posts confused the heck out of me. Ill order the program sometime this week and hopefully get up to where you guys are

Not to mention im always looking for something to do/learn, helps with the quitting of smoking.

same here, not a theory person, just have to do it, good stuff

Just saw your image on the other page and the webpage you had linked for a wiring diagram. I have no idea how you went from that page and made what you did. I think i may need to go back to basics or is their labeling on the programer?
