The Blinkenlight board has an 6809, EPROM, RAM, PIA
and ACIA.
An additional (small) board gives you 64 input and 64 output (all TTL),
but you loose the PIA interface in that case.
Have a look at my website (
www.pdp-11.nl [My projects]).
I do NOT have the boards nor a kit, but ask Vince!
I haven't seen blinkenlight board in your links :oO...Ah, the Home Made
PDP-11? :oD I'll give it a try..would you have a spare core/io boards? :)
