Soon. I have been busy with other projects Such as my Slice in circuit tester and a new out of circuit tester.
I also wanted an option for the Slags chips which are defying reproduction at the moment due to awkward timing.
I do now have a TTL board that will plug into all four Slags sockets on my cartridge. It has 30 standard TTL on it and works perfectly.
I just need to mod the software options to include a hidden game swap method as this will be better and easier than a manual switch option.
I will be selling the cart as two options, one will be a kit of parts to be made up and the other will be ready made and tested.
The only IC's I won't be supplying will be the 6522via, TMS5220 and the four Atari Slags. These will need to be taken from an original cart.
Currently my thoughts are £300 for the kit and £380 built & tested.
If you are still interested, post in this thread to give me an idea of demand if any for this cart.
