9100Bs obtained Message #1 Posted by David Ramsey on 16 Dec 2011, 12:45 a.m.
I spent several hours today with Larry Atherton going over the two 9100Bs he's spent the last couple of months restoring for me.
Both are, of course, functionally and cosmetically perfect. The later unit-- the one that uses a standard power cord rather than the unique power cord the earlier model uses-- has a better CRT, as the display for the earlier unit is slightly dim in the center of the screen. With their rebuilt keyboards, card readers, and electronics, everything else about these machines is as perfect as it's possible to make it.
Sadly, the lowest wire in the flex cable for the 9100's printer failed as Larry was demonstrating how to use it. We verified this fault with a continuity test. Of course the only possible fix is a printhead salvaged from another printer, so if anybody has a dead 9100 printer laying around, let me know. The fault is in the black plastic block that the tungsten printhead wires protrude from, and there's visible, very light corrosion on the wires entering the block. We decided that it's probably better to leave things as they are, since opening the block might well result in a showing of disintegrated flex cable wiring and a totally nonfunctional printer rather than one that simply can't print the last line of pixels.
I shall post pictures soon...
