How many years has it been? Too many. Anyhow, I've finally done what I should have done years ago and re-designed the cart.
The original was hard to build and overly complex. The new version has simplified the construction and the user experience. Game selection is by menu, no DIP switches or button presses

Just switch on, press a key and you're away.
Carts come with all the currently available (working) ROM images as well as BASICs -I and -G, which benefit from an additional 32K of RAM.
Carts are lovingly hand built to order. Price is £40. UK postage £3 1st class signed for. I'll ship anywhere, but I insist on tracked/signed for service when sending overseas.
Facebook usually gets the first pictures over at the
Sord Computers group.
