8I and KA10 bulbs

The bulbs look like the 8 bulbs, they can still be purchased from DEC 12-09169-00 LAMP, 15V @ .040AMP MAX, .075 $2.00 See web page http://www.digital.com/info/DAS-Catalog/dassearch.htm http://x35.deja.com/getdoc.xp?AN=534721209&CONTEXT=956232079.1091174408… On the 8/I I think the serial # is on the back of the frame, one has two plates M26 8I L3221 and M26 8I SYS3194, which is the newer of the machine, it also has a DEC looking piece of paper glued to the bottom of the frame below the wirewrap dated 3/28/72. This is a negibus also. Plates labeled M26 8I L3221 and M26 8I SYS3194. This one has chips 69-72. The older? is M-2 L-927. It has a bunch of blue and other color wires which I assume are ECO's or options added later. It doesn't have any of the option plates on the top of the frame. The one above only has a few. Most of it's chips are 68, it has some of the blue Sprague chips. Sorry, only have the one copy of 8/I manuals that I scanned. David Gesswein
