I wrote a few weeks back about an HP 9000/380... The keyboard I'd found
separately at Weirdstuff Warehouse works fine, and appears to be
period-correct (46021A, serial #3150S50181). However the key caps are
surprisingly loose -- if you tap firmly on the surrounding bezel you can
watch the keycaps bounce and rotate on top of their mechanisms.
I found a seller on eBay with new-in-box 46021C HP-HIL keyboards. The
style of all keycaps on the C model are the same as the alphabetic keys
of its A predecessor -- the A's numeric keypad has a very distinctive
undercut sculpting. Overall weight of the two units is similar, the C
being a bit smaller and lighter.
The new keyboards are $9.99 plus S&H ($12.68 for me in California), eBay
auction #300267813052. There are currently 5 left.
I have no connection with the seller other than as a satisfied customer.
Just thought others might be interested in NIB HIL keyboards.
