Hi Al , I survived VCFMW. I thought you received my reply, but I've been having all kinds of problems. I'll try to have my son or someone send you pics. Thanks, Paul Paul Anderson Aug 23 to Al Hi Al, I have four DILOG boards that the components match the photo you sent me. The difference

The H744 was 25 amp, but then they came out with the H7440 28amp? And the H7441 at 32 amp. A lot of units were upgraded in the field. Paul On Mon, Sep 17, 2018 at 5:49 PM, Eric Smith via cctalk < cctalk@classiccmp.org> wrote: > On Mon, Sep 17, 2018 at 4:17 PM, dwight via cctalk > wrote: > >

Re: Looking for two DEC H445 power bricks for PDP 11/40 project

I had a problem with brick power supplies a number of years back. I found an issue that caused them to fail. I had about ten of them on the same power switch. You'd think this would not be an issue but it is. You see it works like this, each one had a transformer in it. When you disconnect the

Re: VT100 emulation

The BBKey2 has punctuation on the keys. It's not all of them (|, & and \ aren't there), but the SYM key brings up an onscreen keyboard with those. Not ideal, but I would argue reasonable compromise for something relatively modern that fits in your pocket. Not sure about diacritics, but at least

Re: cctalk Digest, Vol 48, Issue 17

I recall the SAGE was an integrated system of control for Interceptors. It began in the 1950's and became fully operational with the F106 fighter interceptor aircraft. It could control an entire intercept from wheels up to flare on landing. I never thought I'd SEE a chunk of the system.

Re: Looking for two DEC H445 power bricks for PDP 11/40 project

H745's are harder to find. I have at least one that needs service but I am located in the USA and I have no clear idea what's wrong with it. Is it that you have zero h745's at all or you have a bad one? Is there a typical point of failure for these? If so, I'd try to track down a bad one and

Looking for two DEC H445 power bricks for PDP 11/40 project

Hello list, last year, I was able to obtain a BA11-F chassis for my PDP 11/40 build-up project. The power supply to run a system in basic configuration is complete except for two H745 bricks (delivering -15V) which are still missing. I'd be very happy, if anybody could consider parting with one
