Past tense is correct. It broke down earlier this year. Anyway, I
finally tuned in channel 3/4 via RF too, but it is much worse than
using composite video. At least the modulator still works.
My 1084 has stereo sound and one DB9 connector for RGB, as well as
the CVBS/LCA connectors. I don't have any other NTSC computer to
verify how it should behave, but it is of lesser importance.
I haven't measured any voltages from the EPROM reader, and I don't
have enough documentation to know how to change the Vcc if it even
is possible on this model. If the chip itself has a bit error all
over it, it may be reason enough for the board to crash on boot-up,
resulting in no display?
