I recently acquired a HP 9825t and have a project in mind that will need a serial interface. I've not had much luck tracking down 98036a serial interface, but may be able to get my hands on a 98046b. Will this combination work?

Thanks,
Tom

The install guide for the 98046B (found on hpmuseum.net) suggests it is only for the 9835/45 and the "Tech Data" sheet for the 9825B/T, the last model of 9825 does not list it as an option. The 98046 is a quite different serial interface with an embedded micro-controller to handle some of the protocol primary so that it can support synchronous serial protocols as well as async. It will physically fit but it is unlikely that the 9825 has software support for it.

A quick search on the internet turned up a couple places that claim they have one, I am surprised they are so scarce, I would have thought they would be a common interface card used in 9825/31/35/45.
