Показать описание
This is the fifth and final video in my series documenting my Harlequin ZX Spectrum Clone build. In this video I power the Harlequin up for the first time, test the ROM images I burned in the EEPROM, run some diagnostics, and load a game on it.

The diagnostic ROM can be downloaded by following the link on this page:

This a the most underrated series on the internet! I am going to build one thanks to you

mine booted on the first go with the basic toast rack rom, but I made some mistakes on the plus 2 rom after and it would give black and blue lines. I did not understand the one I found was split into hi and low, I thought it was version 1 and version 2 so only burned half.

Hi, I accidentally came into possession of Harlequin issue 2d PCB and decided to build one. I would be grateful if someone could give me a link to some kind of building manual. I only have the BOM list.

Are the ROMS on one ROM IC? If so is it freely available as a download to program to a blank EPROM?
