Who has a sinclair scientific programmable?

[Harald]

I bought one a year ago and finaly picked it up at a friends house in the UK. I gave it a thorough clean today and installed a battery. Basic operations seem to work fine, although the acuracy leaves a bit to be desired.

30 SIN, after blanking the display for ages produces 0.84265 ?!?

Also, pressing keys often produces (this is reproducable) brightly flashing digits. Is that normal?

Maybe someone who has such a calculator can confirm this behaviour.

Cheers,
Harald
