And what do you have so far?
What parts do you think you will need for this?
An AC/DC converter; a clock (sic) crystal, at least a four seven segment led displays
or equivalent, a small processor that supports a few digital input/output lines,
quite a bit of rom to store the kvm (a smaller version of the jvm), quite a bit of
ram (128KB will do) and for development I'd suggest an emulator. Of course
those electronics engineers can come up with a lot more components.
My suggestion is: don't do it although it's doable but it doesn't pay back.
kind regards,
Jos
