[N8VEM: 19973] Grant Searle's CP/M multicomputer (Cyclone II version) : updates

[RHKoolaap]

Hi all

Can't leave well enough alone, I guess :-)

I spotted a wrong file in the last package; the MP/M bnkxios source was not
up-to-date.

Also I implemented a new SD-card controller. This one supports SD-HC cards
as well.

I added a proper interrupt acknowledge for the timing interrupt. This
eliminates the discussion on pulse length and it also stops the MP/M clock
from missing interrupts

The question now, off course is; should I implement support for larger SD
cards, say 8Gb, which would hold over 950 volumes. This would require 16
bit volume numbers. This is not hard to do but requires a completely new
installation. Anyway the jury is still out on that one.

This time I only included the changed files. You'll need the previous
package as well
