When I have time, I'm going to build a vintage SBC kit I have, a SD
Systems Z80 Starter Kit from 1978/79:
I believe all the parts are present. It has two S-100 slots, a
wirewrap area, Kansas City Tape interface, 2758/2716 EPROM burner,
7-segment display and hex keypad, with the ZBUG monitor in ROM.

Is there a source for simple components? It seems that bread boarding modern equivalents of the chips used at the time
might do the trick. It's probably easier to get the discrete components up to the basic ttl chips than it is to get the
micro processor and other more advanced integrated chips.

Political correctness is a doctrine, fostered by a delusional, illogical

holds forth the proposition that it is entirely possible to pick up a turd

Consider the SWTPc 6800: there's a box (the computer), a standalone screen, and a large-ish thing with a keyboard. Best I could come up with is to explain that keyboards and monitors are just accessories that plug into PCs, while terminals are separate products that "talk" to a computer over a network. Seems like a decent way to explain this to the masses, technical details aside, right?
These days we use computers to connect to the internet. But back in the old days, a single computer was kind of like a small, self-contained internet in that many people shared it's resources and worked collaboratively within a computer system. They could even "chat" with each other using a chat program on the computer that sent messages from terminal to terminal.
When computers got smaller, but were still housed in separate boxes from the keyboard and monitor, the terminals acted as keyboard/monitor "emulators" via a serial connection.
