Hewlett Packard 9816

At the bottom right we have the keyboard interface, a simple RJ11 connector.
Beside that is the HP-IB bus connector.
And to the left of that again, is the 'communication interface' which is a 50pin RS232 bus.

The cover above the connectors hides the two expansion slots.(If you remove this, and look in and down to the left, you'll find the configuration switches.

This is one of the stranger workstations in my collection. Instead of ONE Operating System, this one came with a choice of THREE different ones, HPL(also used on older HPs), BASIC and 'Interactive Pascal', and they could be booted from either a ROM card or from disc.
This unit, was probably sold with a dual 3.5" Floppy drive connected to the machine witha HP-IB cable, but where it has ended up is anyones guess. (The man I bought it from never got one. )

There may be a problem with the onboard switches as the selfstest registers as the 9816A has 128KB on the Motherboard, and the 9816Shas 256KB, and there's a HP 98257 memory-card in one of the expansion slots, and a manual found on the net indicates that it is a cool 1MB in size, but the selftest indicates that it only has 128KB installed. But without a manual for the RAM card, there's very little I can do to rectify that situation.

A not entirely complete page, but it lists all the models, so is a good read.

This site is stuffed with documents and software for older HP computers. A must-visit!
