What does HP-35 Red-Dot back look like?

[pebinord]

The link to Michael Eckstein's site really helped alot! Many thanks for that!

No, I had no interest in the most recent example on the 'Bay -- but I did scrutinize it closely while trying to confirm the authenticity of mine. I'm clearly no expert but that one strikes me as suspicious. Obviously it has the right ROM but my gut tells me it's a mash-up of various parts. The adapter socket looks like the later style (was this style ever used on original V1s? Was it introduced on the V2?). The main label on the back may be a replacement ("Hewlett Packard" across the top) especially if the back is from a later version -- which would involve removing screws, hence the need to replace the label. The serial number label looks like it may have been peeled from another unit; can't make out the number to tell if it's in the right range.

Anyway, my HP-35BBRD can be added to the known list. Too bad it doesn't have its serial number :-(
