Sharp Elsi Mate EL-420M

[John Murphy]

Hello.

One of these has recently come into my hands but I can find nothing about it on the internet, apart from someone trying to sell one in Switzerland.

Even the Vintage Calculators Web Museum has no details about this particular one.

I can't understand what the difficulty can be.

Does anyone have any information as to how common they are or where I could look to find out anything at all?

Thanks in advance,

John

I think I have one...I kind of ripped it apart To fix display and I could only get it partly to work. Your correct info on this thing is hard to find. Let me confirm it the same model, I don't remember the M but also have not fooled with it for years.
