Also, Eric Kudzin spent some time trying to fix the
CRT, we are making
progress and as part of the testing we need to test a KNOWN WORKING
computer on the Alto monitor/crt. I have a PET 2001, we made a custom
cable (it "should" work), anyone know if the PET video out will work on
the Alto monitor?
Since the Alto is a grpahics workstation with a fairly high resolution (I
assume), I would guess the horizotnal scan rate of the monitor was much
higher than the 15kHz used by the PET. In other words, I don't think it's
going to work.
Can you not use a 'scope or logic analuser to check that the Alto is
giving out sync pulses and some kind of video? If it is, then you can use
that to test the monitor.
