The CFT is a long-term project built in my Copious Free Time. It's a homebrew, self-designed, self-built 1960s-style 16-bit mini computer built out of 74xxx integrated circuits. I've designed the instruction set and architecture and built a working processor on four 3U Eurocards.
There's a full programmer's front panel and plans for peripherals. On the software side, there are emulators, software and documentation in various states of disarray. There are sweeping changes as of Spring 2019 since I switched to using KiCad and can now afford to improve the architectures greatest annoyances.
I tend to be very busy, so the state of this description always lags behind the actual project. The photos I've posted here are really out of date. Years, in some cases.
This is an old sub-project, but it helps show what's available. It's a microcode-level emulator of a basic CFT system. It's very slow compared to the real thing. On a good modern computer, you can get a 1 kHz clock. The CFT itself runs at 4 MHz.
But it shows what's available and how the front panel works.
