[chbot] Robotics Group meeting, 5 Idris Rd, 630pm, Mon 21 July 2025 - with special speaker

[bill at galumf.com]

Thanks for the great talk from Dave.

I and my son would be very interested in a talk about ‘building your own flight control processor’ . My teenage son has already done a 16 bit processor design. Half adders, ALU and control logic. He’s been thinking about his instruction set. The things Dave discussed tonight, very inspirational.

I have to agree with Dave about the DEC designed StrongArm processor. This powered IMHO the arguably best portable computer (of it’s time)
