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.
