I've been spending a bit of time writing the memory tester for my Sinclair Spectrum Diagnostics board. The board itself, to recap, contains a flash ROM, a little bit of glue logic, a couple of flip flops and eight LEDs - the idea being that the code running in ROM can display the results on the LEDs, so as to use as little of the (possibly suspect) Spectrum's hardware.
Work expands to fill the time available. -- Cyril Northcote Parkinson, "The Economist", 1955
