I think the problem with most old SUN frame buffers is that they run sync
on a separate channel. Most other vendors mix the green and sync channels
into a single one. However I don't remeber if SUNS sends both syncs or
just the vertical sync. Thus some monitors, spedially older multisync
ones, may not like that.... either they spect the sync channels each on a
different line, or they can deal with sync-on-green.

The ZX gets awefully hot, maybe that chassis is not cool enough for it.
But I do not think why it would not work....
