That's a cool story. Who knew

That's a cool story. Who knew CP/M was green at CES '85! I love the story how Von Ertwine whipped out a disk editor to update CP/M for the current 8563 of that time.

Fred and Terry keeping a close reign on those reviewing their work was a wise decision.

So, at CES '85:  was it you guys (you and Fred, Terry, Von, Dave and Frank) actually at the keyboard demonstrating the 128 or were you guys there to supervise keeping the chips from melting and the voltages at an optimum level?  I wish there were pictures of the demonstrations!  That would be golden!

They were still bringing

They were still bringing working VDC's to us even as the show opened, people would report in to our assembly room that was supposed to be a marketing meeting room (Our booth was so big it had a second floor) with one or two VDCs that had just passed testing half a day earlier and we would install them. Then the other adjustment was that we would walk around with a tweak tool and for systems running multicolor character mode (VICII) games we would teak the voltage down and for VDC based we would tweak the voltage up. Then some of the VDCs had a text screen that was light on dark and some dark on light. We had built little pull-up and pull-down modules to sit on the output lines that made them pull up or down faster totallly abusing the max current max power ratings of the chip.

The room that we did the tweaking and that Von sat in to hand edit the CPM disc can be seen here: http://www.c128.com/images/scan0011.jpg and the whole series at http://www.c128.com/gallery.htm

Such great pictures
