Hi,
I just found two small lamps in a HP packaging and was wondering if someone
knew for which system these are ?
Part number is 2140-0203 and the text on it says LAMP, INCAND. 5V
Written with a marker on the packag is STICKER LAMP and LOAD POINT
Anyone any idea's ? It came with a bunch of HP1000 items.
Stefan.

I have not taken the
time to look up these part numbers yet, but my guess
would be lamps for the pushbuttons in a 7970 tape drive, and perhaps the
load point tape sensor?

The HP 1000 "CE Handbook" says that this is the "photo sense" lamp for
a
7970B/E tape drive (i.e., the BOT/EOT reflective sensor). See page 71-1

Ahaaa :-) Not that I have any use for them though, so if anybody wants
them, they are available for swap.

Hmm, 2114's, 2115's, and 2115's all use higher voltage lamps for their
front panels.
I'm stumped on where a 5-volt bulb would be used, unless its the small
solder
in bulb that goes on the parity error option for a 2116.
