IO running on the new clock and flip flop

A project log for The Cardboard Computer - IO is my name

My goal is a 4-bit CPU using recycled cardboard substrate and Diode Transistor Logic. This is an educational platform for me.

I have hooked up the new astable multi-vibrator and master slave flip flop to IO and the sequencer. Looking good :-) Yann has waited a long time for this ;-)

I like the wire "X" in the middle of the astable!  It just looks right.

Hey Ted, yeah I like to wire it the way I see it :-)

Thanks David :-) Been making slow progress as well as keeping up on your project :-)

Yeah man, the CCD circuit is on hold for now, ( I think the 8-bit resolution is NOT going to do the job, so...) I had to re-direct the project on a new path, with the help of some partners in Ecuador, who would have thunk??

Nice, so you've now managed to junk that nasty 555 you've been using? XD

  Are you sure? yes | no

Hey Jez :-) Yup, the 555 is now in the what not bin for future use :-) BTW the new clock is the one used with the servo display unit :-)
