How many points for those experiencing HP3000 failures due to
the Cobol instruction set firmware chip being installed wrong,
and missing one pin?

How many carried around the SOS chipset for the 3000 processor in their
wallet.
(HP was were giving out failed silicon for the 5 chips that made
up the series 30/33.) At the time, I think it had the highest transistor
count of any commerically shipping product.

Do you remember the HP2640B, that shipped with only 1k byte of screen
memory?
If you didn't buy a 4k byte add on memory card, you couldn't even
display an entire screen!  Things like display enhancements required another
card as well. The thing ran up to a whopping 2400bps, but of course, it
couldn't
really keep up with data that fast without the old enq/ack handshaking
HP used to be famous for.  I think they ran about $3,000 at the time.

And yes, I did keep a 'key' on my keychain to open the 264x terminals. I
couldn't
keep one of the red plastic adjustment tools for the 262x terminal series on
a keychain
but often had one in a pocket. I also kept an HP equipment
key so I could open up disc and tape drive cabinets as well.
