I have one of these in a box somewhere, along with the PROM writer...... very funky little unit, well ahead of its time.

When I did A-level computing in 1990, I remember doing a case study of how the UK music singles chart worked. Shops entered details of sales into little computers, and I remember that the Epson PX-4 was specifically named. No idea if it was true, though!
