Restoring a HP9830B calculator.

[Tony Duell]

Well done! It is always nice to hear of one of these fine machines running again!

The tape cassette you have is the system programs for the disk system (the part number of the HP9830 'cable' is HP11273, and this number is used for associated things like the ROM cartridge and tape).

I believe there is an image of this tape included with the 9800E emulator, so it may not be necessary to image it.

I also have the disk system, but it didn't start out together. I found the controller and the 2 'cables' on E-bay. I also found a brand new 13215 PSU there. And I rescued a 7900 drive years ago.

Restoring all this is probably going to be my next big project. Unfortunately I have other, non-HP, things I have to do at the moment, but hopefully I can make a start on it fairly soon...
