HI !
I've built a full speakjet interface, with commodore keyboard, a year ago, and still not working.
Keyboard modul works perfectly ! (lcd, memory etc., everything fine)
K-II application, the same, lcd shows everything, and reciving midi data from k64 or external.
But the speakjet is dead, it says ready on start, and after enters in a weird cycle of woawoawoa.
The 16f88 pic is well programmed, and i tryed every variant of code, nothing works.
I've checked, every month the paths, and wires, and everything it's ok.
If i pull out the 16f88, and shorten the pins for test on speakjet, the test sound it's ok.
The only thing i didn,t check is with rs232, beacause i don't have the max, and no rs232 on computer.
And i'm not a novice, i've built 2 sid projects and many other synths, this is the first with so much trouble !
Pearheaps the Speakjet is dead ?
Suggestions ?
Thank you very much !
