Re: Simulation software

Got the point even if the last sentence is a bit scary for the testing I've to perform for the new ideas... I've almost finalized the reasonings and hope to be able to publish the results in the short time. Hope then you'll find them interesting enough to support me a bit in the realization!... In t...

Re: Simulation software

Seems to me that 8x4 matrix as it is available with current lines is not suitable for direct keycode wiring, anyway this is a simple lookup of a very low frequent event. Instead I was trying to understand another thing (and sorry if the question is trivial but I'm pretty new on electronics): I red a...

Re: Simulation software

Yes, I saw, but unfortunately this is adding even more circuits, even if external... (and added also to the one in the keyboard itself!) For me to remain pure with the 70s philosophy the keyboard should be a very simple integrated old school matrix one! The solution I was thinking was routing the (4...

Simulation software

Hello Marcel and all the "co" Tech aficionados! I watched by chance a youtube video about Gigatron and started get interested about homebrew CPU design! :) I analyzed the project and found very nicely designed and explained. I also proposed (on the hackaday blog) an exctension of the instruction set...
