Part 2 of the Spectrum 128K toastrack fix: building the ByteDelight ZX Diagnostics Cart kit and testing a faulty machine that passes everything with the cart fitted.
After the fire, Ben Versteeg of ByteDelight sent a box of Spectrum goodies: a 128K toastrack, ZX-HD, DivMMC EnJOY Pro, ZX Diag and a Harlequin 128 kit.
A Retro Asylum Spectrum +3 gets the audio distortion fix, a SCART compliance fix, a full 3-inch drive refurbishment with a new belt and a keyboard clean.
Building and road testing the ByteDelight ZX-HD plug-in HDMI interface for the ZX Spectrum, with an RGB SCART comparison and an honest verdict.
The DivMMC EnJOY from ByteDelight adds SD card loading and a Kempston joystick port to any ZX Spectrum. I test it on a vanilla 48K.
