But who wants to write the software?
I am building a 1977 ttl style computer because now I have spare time.
Finding vintage or similar devices is being a challenge as well fighting
modern OS to have even a C compiler and a TEXT editor.
Technology is not better, just cheaper.
I plan to use a low of LOW POWER 22V10's and undefined ALU logic
since I have several designs I want to play with. NOW is your last
chance to buy small quantities of things like 2901's and small TTL RAM's
and floppy disks.

I don't think Indivudual Computers make the
catweasle any more. They never
released a 64bit Windows driver for it.
In point of advancing technology, one can purchase a STM32F4 development
board with USB, UART, microSD, battery-backed RTC and oodles of timers
and I/Os as well as a TFT interface for less than $12 shipped. Almost
all I/Os are 5V tolerant--and can be configured as open-drain if
desired. 192KB of fast SRAM and a CPU running at about 168MHz.
Perfectly capable of doing sampling of floppy output.
Why would anyone want a Catweasel at this stage? Technology has moved
past that.
