Re: Multiflow Trace 14/300 close to being scrapped in Texas

Awesome news! I'm happy it's going somewhere to be cared for or at least stored. Seeing systems like this get scrapped hurts my heart, losing history that is there and still alive ( reasonably anyway ) is a shame. I'm just happy that it will live to blink another day ;) On Saturday, July 23,

MM11-L / G231 repair advice?

So after replacing a microcode PROM on the PDP-11/05 control board and then concluding that the remaining problem relating to indexed addressing was caused by one single micro code line that got missing when typed in, desoldering the PROM, program two more bits (0xf to 0x5), the CPU is now

Re: Possibly rarest Apple 1 ever for auction

My guess is that is was a test board for Apple. There are some weird mods to the ram timing with a variable cap and to the negative supply that looks like they were experiments to figure out the tolerances of the chips. The board was wave soldered. You can't fake that on an Apple-1 because

Hi Mark, it wasn't myself either. Apologies (and to Brian, James and Jon) I was watching & wanting to respond but got hit by a wall of things, then noticed that someone had bid on it. Very glad to see it was acquired, and that Chris could confirm.
