I've started another thread for the multi-cart, there's more then enough interest, so I've been coming up with a plan. I'll get my old Lynx out of the attic later and do some tests.
Not to derail this thread, though, so back on topic... an update would be great on this. Even if it's "not had any time, doing other projects, will come back to it when I feel like it", would do. I know that feeling all too well, I've got another project basically finished I need to actually make up some units for sale. Annoyingly (for the consumer) it's the challenge of making things work which is the exciting part, when it comes to the logistics of building units and electrical or mechanical sticking points, things get boring really quickly. And unfortunately us hobbyist electronics types (well, I speak for myself anyway!) do this for the challenge and the fun of it more than the monetary gain. For me the money I get for doing these sorts of projects (which isn't a lot) just goes to fund me to buy more kit to help me do more daft projects.
That all said, I'd love a new screen for the Lynx. It's such an awesome bit of hardware.
