I'd just like to mention that I have completed the repair of a vintage 1976
HP9830B BASIC calculator and HP9866B printer. If you are interested in the
Congratulations on getting this fine amchien running again.
The HP9800 sereis are among my favourite machines. Small enough to carry
about (just!) but the CPU is stil lbuilt from simpel TTL and thus can be
investigated. They're also nne of the few bit-serial machines you're
likely to come across.
