I’ve an #AmstradCPC464#retrocomputer. Is there a way to use external ROMs to update BASIC to 1.1 and so get access to ROMs 7..15? If so, what ROM images in what slots? (I have a DD5 so effectively have extra RAM and Amsdos ROMs).
@devlin@GrantMeStrength there was one ROM board that allowed this back in the day it was the "ROM board extra" from microstyle. It had 6 slots 1 to 6 and a 7th socket that was mapped to lower and 0. You put your 32k 6128 (or 664) ROM in here and it then gave you basic 1.1. nowadays it's easier just to desolder the ROM, fit a socket put a 32k EPROM internally.
