Setting up Mame / Mala with rotating CRT (Mrotate4)
DaOld Man:
Ok, here are instructions for setting up mrotate4.
There is also pics of how to set up start com in mala to run mrotate4.
Sorry if I made any typing mistakes, its late.
I have laid them out in the order that you need to go by to set it up.

Good luck, and holler if you need help, and let us know how it turns out.
Ropi Jo:
That is fantastic and so kind of you to take the time and trouble.
I'm off out with the family for a 90th birthday meal so will try to implement all this when we get back and update.
BTW... it's not my 90th!
DaOld Man:
Safe travels and tell them Happy Birthday from DaOld Man.
Ropi Jo:
Today I installed the serial card and mrotate4. Followed your step-by-step to the letter...... and it worked exactly as you described. Used a couple of LEDs with 1K resistors and could see the outputs doing their thing.
As you also said, there is quite a bit of activity during windows boot so need to block the outputs for about 30 seconds, which is no problem. Also will add some blocking diodes for the -ve voltages you mentioned.
Salvaged a couple of optos, transistors and relays from some old boards and started with the interfaces.
Getting real close now!
Ropi Jo:
Built the interfaces today. One of the 2 didn't work straight off and while investigating I blew up the opto, the back emf diode and the switching transistor. Decided I was doing it the hard way with pnp switching so redesigned and built both with npn. Much simpler and both worked 1st go. Using a 10K current limiter into the opto I only draw 0.45mA from the 5v test supply so very pleased with that. When I add the blocking diode I may need to drop the 10K a bit lower. Then just got to add the 30 second lockout timer and it'll be ready to hook up
