Restoring a HP9830B calculator.

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

Thanks! I really like HP machines. There is really a sense of quality about them.

Quote: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.

You are right. I recognised that the ROM cartridge has the same ID.

What is the procedure to image a cassette?

Quote: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...

I am looking forward to hear your story about the disk sub system!
