Before I found amateur radio I spent a lot of my time with vintage computers. In fact, the reason why I started amateur radio is that Dale MM0INH and I used to run Retrochallenge together, and he kept banging on about how much fun Amateur Radio is. Eventually I looked for a local club and found FARS were running a Foundation Course in a couple of weeks, and obviously have never (really) looked back. This is the first vintage computing device I’ve bought since becoming an M6.
At one point I had an Epson HX-20 with built in printer, but that has poor display, not much better than the original Casio FX-720P. Heavy too.

The other option I seriously considered was to get a Psion 3A.

I had one of these for years and to be honest it bettered the Psion 5 in a lot of ways. However, when it comes to weight the Casio’s beat it hands down.
When it comes to repurposing old tech I did at one point consider printing reports via old tech (daisywheel printer) and scanning them back in again, but that seemed a step to far. That’s why your suggestion is silly too 
HF was a real struggle yesterday, and my ‘bang up to date’ Android phone suffered from Summit Brain with no mobile phone signal. I assumed it was because of the location on the fell, although I was a little surprised I got nothing, then when trying to ring my daughter later found that it had forgotten how to talk data and needed a reboot. So this activation was done with only one spot kindly provided by @G7CDA Douggie for 20m via 2m. I don’t consider asking another operator to spot you on a new band cheating, that’s a novel use of radio in my eyes.
