Hi @Tony Robinson - Thank you for following my #Homebrew CPU list!

  Are you sure? yes | no

Hi Tony, thanks for liking and following #1 Square Inch TTL CPU ! My current project is #Kobold K2 - RISC TTL Computer.

  Are you sure? yes | no

Hi Tony, thanks for liking and following #One Transistor FlipFlop ! Did you also look at #ALU in DCTL technology ? It might be useful for your CPU.

  Are you sure? yes | no

Hi @roelh , thanks for pointing me to that, I do appreciate all your input here.  I've learned a lot and am happy that I have a lot more to learn.   I do have to pace myself, so have to (a) write up the new memory cell (which does use transistors to drive transistors BTW) then (b) fix the carry propagation on the ALU as if it's slow there is a temptation to use shift registers and a 1 bit ALU (but I don't really want  to go that far) then (c) dig out my last ALU design (I may have lost it) and of course build all the state machine and other gubbins.  I am feeling hopeful that if I can halve the number of components then I will finish.    Oh, I'm very tempted by PyRTL, if I could get that to generate Verilog that ran on my FPGA that would be a huge step forward as well.  SO much to do....

And thanks for liking and following #ALU in DCTL technology ! If you want to connect your device to a Raspberry Pi,  look at #RISC Relay CPU or #1 Square Inch TTL CPU where I use a RPi to assemble the program and put the result in the parallel Flash memory. You want to use RPi as main memory ? I think your cpu will be more impressive when it runs stand-alone without any help of a RPi.

Hi Tony, I'm glad my project #RELAY COMPUTING is of interest to you. I hope you will find my project #SANX-I MICROCOMPUTER interesting as well. Best regards, Javier

Awesome lol. I guess you probably have heard this before, but..
