Hi all.
Things are progressing nicely.
The core board is tested and works. I get the monitor prompt
on the VT220 terminal connected to the RS-232 interface.
That means there is also software for it. Go to the updated page
http://home.hetnet.nl/~tshaj/pdpsite/homebrew/startframe.html
Next steps are:
1) adjust monitor software so it runs without the RAM 5565 chip
2) build the I/O ports interface board
3) write the "low-level" in- and output routines
4) write the "stand-alone" pattern SW (the Cylon-eye on the DATA LEDs)
5) the real work: interface with Ersatz-11 (..John?)
The monitor software (e11-6802.zip) already contains some SW
but that has not yet ran; it just assembles without errors ...
