: Verifying the standard 256 x 192 pixel resolution and the 15-color palette (including bright and non-bright variations).

These are programs loaded from a or disk (DSK) image. These run within the Spectrum's standard environment and are best used when the machine is already functional enough to load them. They are excellent for running burn-in tests, performing thorough system checks, or verifying system stability after a repair.

A: Yes. Unlike some “burn-in” programs from the 80s, modern diagnostic suites do not over-stress the ULA or transistor driver circuits. However, do not leave a pattern test running for 72 hours straight on an un-heatsunk ULA. : Verifying the standard 256 x 192 pixel

What is the computer currently showing? (e.g., black screen, garbage patterns, tape loading errors)

Using terminal software (like PuTTY), you can stream data or send specialized testing routines directly into the Spectrum’s memory banks. Step-by-Step Diagnostic Routine
