Setting up Mame / Mala with rotating CRT (Mrotate4)
Ropi Jo:
As soon as progress is made I'll update.
At my age (and failing health) spending the entire weekend playing with cars is not my idea of fun. Actually got the wife's car sorted Saturday but as all the tools were out it made sense to get the outstanding work done on my old wreck as well. The sun was shining all weekend so it was a no brainer. Was pleased to go back to work today for a rest!
DaOld Man:
Hope your project is coming along ok. Something you need to keep in mind about the comport outputs.
When "off" the pin actually goes negative around 12 volts to ground.
When "on" the pin is around positive 5 volts to ground.
Just keep this in mind. Its not a bad idea to use diodes to block the negative voltage.
If you isolate your circuit from the comport using optoisolators, you dont have to worry about it.
Ropi Jo:
Thanks for the heads-up old man.
No progress this weekend either as taking advantage of the fine weather again to do a bit more work on the car and some work on the front yard amongst some other chores.
After next week at work I've got a week's vacation booked (see... I'm learning your language). Just got the new exhaust to fit on the car and the rest of the week is mine!!! Hoping to get some good progress on the ROPI-CADE.
Ropi Jo:
My apologies to the old man.
You've worked hard and fast to produce the software for me and I still have not got round to installing and testing it. I feel I'm letting you down.
I've just had a week vacation and have been doing home chores all through it. Not got anywhere near the ROPI-CADE.
Please don't think I've given up on this. Far from it. I've done all the essential home work here and finally I'm clear to start playing with my toys again.
I'm back to work tomorrow unfortunately (although looking forward to the rest) but should get some playtime in the evenings and all weekends, and I've got another week off late in August.

No problem man. I understand completely. I have been busy working on the MRotate5 version, using USB. Think I may be getting there.
