Default Re: MK14 schematic revisions

I'd definitely want the revised rom, if only for the tape routines.

The single step function is intriguing, I have often heard it mentioned (usually in reference to needing to pull SenseA down for the new rom to work) but have never seen a circuit. I presume it involves latching the "I" status from the bus during NADS and then raising an interrupt on the sense input if it is high.

When you have a moment, PM me your address and I'll post them out to you, It'll be in a week or two because I'm still in the throes of clearing out mums house and finding places for all the "treasures" I'm finding!
