Hi Chesh, thanks!
You are too kind! A big part of the development, and the biggest thanks! go to @username@ and his amazing coding-skills!
The joystick-part of the proto is yet untested, will check everything extensivly in the next few days...
Cheers, TOM:0)

What a nice Christmas morning!

The PCBs work perfectly, Keystrokes and Joystick (as good as it gets ;0))

Next step: Designing a 3D printable case...

Such exciting news!
Can't wait to get the old girl working again. Both my controllers are toast.

Hi Chesh,

Now I have replaced my faulty MT8808, I can confirm this works fine.
I was even able to type in Noel's (Of Noel's Retrolab fame) BASIC speed test.
Bad news, folks. the Creativision basic is really really slow! :-)

Hi Chesh!

Thanks for the testing!

Yes, the CV BASIC is very slow :0) (partly as i understand because the CV has only the 16k Videoram and every access has to be made thru the VDP...)

The CSL Cartridge BASIC (Laser 2001, Salora Manager) is much faster and has RAM to use :0)

So, need help setting up a GitHub account so you can share the design? :-D
I can already see some minor improvements that could be made. (Smoothing caps are probably the big one. I'll also be investigating if something like a Teensy 2 can be substituted for the Arduino, as well as moving power onto the board. If we can get more I/O pins we could look at two controllers and using Genesis controllers instead, which have all those extra buttons)
