Some friends and I have a pdp8 here.. we replaed the bulbs with leds about 25 years ago, but last time we tried it, it still ran.. model number escapes me.. its currently at a friend's place. It was the controller for a DISTEC (?) display, the predecessor for the wonderful gt40 and used as a frontend for teh pdp10 (KA10, serial # 6) On 3/12/2016 12:07 PM, Larry Rosenman wrote: > On 2016-12-02 22:02, Kevin Oberman wrote: >> On Fri, Dec 2, 2016 at 5:59 PM, Greg 'groggy' Lehey <grog@freebsd.org> >> wrote: >> >>> On Saturday, 3 December 2016 at 11:40:36 +1100, Dave Horsfall wrote: >>> > Be there an implementation of FOCAL?
