We're
talking about putting in a rather complex computer to generate
a baud rate. Are people really that handicapped when it comes to
building hardware nowadays?
Speaking for myself, yes.
Unfortunately I believe you. Use at least a thousand times more components than
you need to.
Now, if the alternative is reading up on crystals,
oscillators, dividers
and related support chips, figure out where to buy and then wait for the
parts to ship, which option do you think I will choose?
In general this worries me if you are restoring a vintage minicomputer. How on
earth can you hope to fix a TTL-built CPU without knowing the common TTL chips
and without having a few on-hand?
