RE: Restoring a HP9830B calculator.
I haven't got around to actually debug the tape drive issue further, partly because the extender board hadn't arrived yet.

Yesterday I drove down to Norrköping and found this nice HP9810A:

The picture is lousy and the machine was quite dirty. It has probably been sitting in the storage container for many years. When flipping up the printer cover I discovered a sticker telling that last time it had been at HP for service was in 1979...

The best thing with this was that it was free except for 40 litres of gasoline to get to Norrköping and back.

So now I got myself another project. (don't tell my wife, though...)
