@DoctorWkt I've made 1-2" square ATMEGA PCBs before. There are trade-offs in the design. Many simple RISC V instructions take 40+ microcode instructions (cycles) to execute, as this is an 8-bit datapath executing 32-bit instructions. I'll put some of my scraps of design up on the internet.

[Chris Dew @chrisdew]

@DoctorWkt Inspired by your Crazy Small CPU, I designed an 11 chip (7400-series + RAM/ROM) CPU which should execute RISCV assembly code (when assembled into non-standard instruction format). Would you recommend designing a PCB over using Veroboard (which is what I have currently laid out)?

@DoctorWkt What is/are FOIL? Are they (a*b)%16, A*b, a*B and (a*b)/16?

[Chris Dew @chrisdew]

@DoctorWkt P.P.S. Your diagram has on /8 going into LowALU. This is asymmetrical, whereas A * B is commutative. If both A and B were /8s into LowALU, it could work, but then again the HighALU would be pointless.

[Chris Dew @chrisdew]

@DoctorWkt As the HighALU needs all eight bits of each register, the LowALUToHighALU path is probably pointless.

P.S. I know you've already found a larger EEPROM, but the problem interested me.

Trust is falling. Why? And how can we fix it?

My interactive guide to the game theory of trust is now OUT!

The important point here is UK could always have better controlled borders but chose not to and then blamed the EU.

Encryption logic.

[Chris Dew @chrisdew]

@chri_hartmann Just read https://t.co/OFugKgO5GO Tried the "encrypt and decrypt text". The encrypted text has noticeable patterns.

@Eurostar Thanks for the information, I'll need to book as soon as the tickets become available.

[Chris Dew @chrisdew]

@Eurostar Thanks, but are UK school holiday fares substantially higher? Can I see last years prices?

[Chris Dew @chrisdew]

@Eurostar Your website does not yet allow me to book travel in August. Are UK school holiday fares substantially higher?

[Chris Dew @chrisdew]

@UPbridge_gap So that's a "No" then, rather than "Yes"? 2560x1440 aka 1440p60, 1440 > 1080. Thanks for responding.
