9100Bs freshly acquired, weird variations

[jackrubin]

HP switched from the earlier (pin-style) oval connector to the "standard" IEC connector during the 9100 production run. You can find illustrations of both types on page 29-30 of the 9100 Service Manual (09100-90034), available at hpmuseum.net.

My experience with HP machines of this vintage has been that HP used an adhesive to attach the s/n and name plates to these machines that tends to dry out and fail. On my 9100A, I had to reglue the serial number plate (loose, but held on by the power cord). The front identification plate fell off and was lost.

Enjoy your new machines!
