The site has some really nice PDP-5 photos which I was wondering if that person could/would put in the public domain, so I can use them for a PDP-5 article I'm working on for Wikipedia and the CHWiki. So I'd like to get in contact with them. Noel

"documentary"

by cctalk＠snarc.net

The video is produced by an openly libertarian organization: https://www.youtube.com/user/ReasonTV/about. It's an interesting story but that is propaganda not a documentary. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)3 educational non-profit evan at vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation

Which Dec Emulation is the MOST useful and Versatile?

by cclist＠sydex.com

On 10/27/2017 01:01 PM, Paul Koning wrote: > Oh yes, and if you look at the wire lists (on Bitsavers) you will get the length of every wire in the machine. The trouble is that, even if you use the documented delay per foot, things don't necessarily match. The stated logic stage delay is 5 ns, no special numbers given for twisted pair drivers. In my model, I do everything in 5 ns multiples (to keep the simulation time under control). That works pretty closely, but not 100 percent, not for some of the CPU pieces. The other thing that's nuts is that the CPU effectively has a 20-phase clock: the documentation shows clock signals with offsets from the reference time given in multiples of 5 nanoseconds (for the 100 ns clock period). And yes, it matters. And yes, many (I'm not sure about all) of the 20 phases are actually used in the CPU. I can't recall, but didn't the 6600 have something like 10 clock sources, all kept synchronized? In any case, it's a gross oversimplification to say that the 6600 had a 10 MHz clock. --Chuck

Apple II no video display

by dave.g4ugm＠gmail.com

Folks, I have an Apple II that produces one beep at power on, but my monitor says "no video present". A scope on the output shows frame sync but at low levels. The odd thing is that ic A9 appears to be a 74S151 not a 74LS151. I wouldn't expect this to work, but I assume it was working at some point in time! I have done some googling and can't see any reference to this substitution. Is it something any one else has seen? Dave Wade
