[comp.sys.mac.hardware] SE/30 2-page monitor/direct slot woes

spector@brillig.cs.umd.edu (Lee Spector) (11/02/90)

My friend has an SE/30 into which he has attempted to install 3 Cutting
Edge monitor-card/monitor combinations (2 page black & white), and
2 MegaScreen Rivals (also 2 page black & white).  He has had a wide
range of non-functional outcomes: 1) crashing when "identifying" from
the monitors cdev; 2) recognizing the card (without crashing) but
the monitor not showing anything; 3) working fine for about 3 days and
then going to outcome #2.  He had one of the cards checked out by
the folks at MegaGraphics - it was OK.  Some of the cards were installed
by professionals.  With so much failure it seems like the fault might
be in the SE/30, but the SE/30 seems to be working fine in other respects.
Question: what could be causing this?  Has anyone else had a similar
experience?  Is the direct slot known to be flakey?  If so, can it
be de-flakified?  (How much $$?)

Thanks for any insights.
