I think the clear dispersant is a isoparafine,
probably the deodorized
kerosine used for camp stoves would do. I still have a 3436 400 DPI color
plotter in the corner of the junk room at work. We used to use it for PCB
plots, I built my own PC interface card with FIFO and output handshaking
state machine logic for it many years ago. Now it just sits. I'm to lazy get
rid if its 600? pound carcass. BTW it uses a TMS 9900 derivative for
control.
My V80 has a TMS9900 seires procssor in it too, along with some state
machines (I think there may be a 2900-series sequencer chip involved) to
cotnrol the timing for the signals to the electrodes.
On a more genrarl point, why do namy collectors regard old
printers/plotters/other peripherals as 'junk' while processorts from the
same vintage are 'interesting'? As I've said before, I'm very much a
hardware person, and can find interest in all sorts of odd hardware.
Yes, procssors are interesting -- of course they are. But to me the motor
control logic of, say, an HP7245 printer/plotter is more interesting than
many microcomputers. So is the electrode control logic of the V80.
