Re: [TCLUG:20067] ancient computers

I can talk more about memory than cost.

These machines had 4K, 8K, and 16K memory cards.

(See:  http://www.cs.virginia.edu/brochure/museum.html)

There used to be classic 3 board computers, CPU card,
memory card, and an I/O card.  The memory card might have
1K or 4K on it.

Eventually the I/O card added floppy controllers and serial
ports, and then it became practical to have something like
an operating system (CP/M-80) and a programming language
(BASIC).
