* Photo Mask, 8080 front panel (rev. 2)
NOTE: The mask is an exact computer-generated reproduction of the original I8080 mask and is laser-imaged onto 4-mil film.  This results in each mask being a “master” with crisp, sharp, perfectly aligned graphics, as opposed to the originals that were second, third and fourth generation copies of the original hand-layout artwork which was photographically reproduced.
193-3010015N/A
Paper Backing, die-cut
NOTE: The paper mask is die-cut from 90# white index stock using a new computer-generated cutting die. Its purpose is to provide contrasting white background to the clear areas of the IMSAI 8080 film mask.   Alignment perfectly matches the photo mask above.  Due to variations in original 8080 production, no guarantee is made that your old film mask will align without some minor trimming.

Replacement handle note:  We’ve had a number of folks who have ordered complete switch assemblies when all they really need is just the handle, or paddle.  The handles are easily removed and replaced without having to disassemble anything.  Unless the handle is completely missing, just slip a thin-bladed screwdriver along one side or the other of the switch handle (where the plastic handle is attached to the switch body bracket), and gently pry or twist the the screwdriver while pulling the handle to the opposite side.  This will compress the handle body and bracket enough to allow the molded-in handle pivot pin to slip past the switch body bracket.

To install a new handle, position the handle over the switch actuator and slip the pivot pin of the new handle into one side of the switch handle bracket, pulling the switch handle slightly to one side.  Use a thin-bladed screwdriver to gently compress the other side of the handle so that the pivot pin can slide into the switch body bracket pivot hole.  This is easier to do than it is to explain! This should save much time, money, and effort for those of you renovating or restoring your IMSAI.
