Re: Sharp Compet 18
That's a lovely example, should clean up really nicely with a bit of work.
Aside from the odd dodgy contact machines of this type from this period these tend to be pretty reliable. Often the biggest shortcoming was the lack of any form of debounce circuitry in many models which could quite quickly render a machine with an even slightly touchy key contact almost totally unusable. Especially with some of the "inventive" ways some companies tried to reduce the component costs for the keypad.
I've a similar example here that's a little later and sadly has lost the stylised display, using a single flat panel VFD. This earlier one looks far more visually appealing.
