Hey I have 2 Planar Cleanscreen 486 also (one is
dualscan and I screwed the
VGA up, the other is TFT). Do you have the external floppy drive you that
thing?
Yes and no... I tore my unit apart and spent an afternoon with a DVM
and a pad of paper and reverse-engineered the DB25 external floppy
connector. I rigged up a simple, non-robust
25-pin-ribbon-cable-to-34-pin-floppy-connector harness and pulled a
+5V-only (no +12V required) Matsushita floppy out of the junk bin and
got it going that way.
I do not have a packaged floppy for the unit. I also do not have a
DB-44HD (3 rows of pins in a DB shell) external CD-ROM cable - wish I
did.
I never did find any 8MB SIMMs for those units, the
other types I installed
did not work.
At the moment, I only have the RAM that came with each of my boards
(in the Planar housing and in the keyboard bases) - I haven't had
anything, really, to attempt to upgrade any of them with.
