Hello! I’m form Brazil, and I have a problem with high end systems “Technobeam”.
I’m electronic technician and have six fixtures technobeam: 3 run perfect, and 3 doesnt work.
These fixtures with no working have a problem in the microcontroller (I buyed without micro of other technician).
Ok, I buyed one new microcontroller (mc68331cpv16), and turn on the fixture.
But, he don’t work…run the display, but no reset and no show true caracters.
Can You help me? I tested the eprom (29f010) in other fixture running, and are every ok.
On the pcb have an HD1 connection. Is it an ICSP connection? Can I use this connection for upload the system?
Thanks, and good year for us.
