But that may be coloured by a career as typographer and finished artist. No software can apply the judgment that humans did in the print edition; it's only more or less degrading steps from that point on. And to be clear I'm not at loggerheads with Johnny because I am indeed talking about acceptable archiving practice, not some conversion of a particular text which might be useful for a particular person on a particular day. --Toby

Honeywell/Bull DPS-6 deskside info?

In a prior life I managed the GCOS OS and communications on a Honeywell 6000. The first year I worked there we swapped the core for MOS memory, swapped the 120MB Ampex disks for 240MB MPI disks, swapped the Datanet 355 front-end and two 716 front-ends for two DPS-6 front-ends, and shrunk the size of the system by 30%. If I remember correctly, DPS-6 front-ends used the memory parity bits to make 18-bit memory, half of the 36-bit 6000 memory. We added a second I/O multiplexer, second CPU, more tapes, and more disks when it was upgraded to a Level-66. This was something like upgrading the architecture from NSA to NSB? We added a Honeywell Page Printer System. This was a really fast (for its time) printer that could perforate, hole punch, and collate the pages. I remember something about renaming the system to a DPS-8/70, but that was more marketing than technology. Eventually it was all replaced by a bunch of Tandem Non-Stop systems in a distributed network. -- Michael Thompson

I'm not sure which is more amusing: http://www.ebay.com/itm/191523958984 the price they expect to get, or calling it a 'mainframe'. Noel

Half an extra finger (DEC PDP-8/A G8018 regulator)

by charlesmorris800＠centurytel.net

As I've periodically posted, my 8/A has an intermittent power supply problem (Power OK light and signal line flickers, so the entire system is confused. Throwing the DC breaker and resetting it will often make the problem go away for the rest of the evening). It's slowly getting worse, to the point where tonight the Power light wouldn't come on at all. It's not the breaker itself. So I decided to put the G8018 regulator assembly on the extender card. However, when using the extender, the DC breaker would immediately trip! I tracked it down to the +5 volt crowbar being triggered. Careful examination of about four different schematic pages shows a connection on the backplane between edge connector pins BP2 & BR2 and the multiple +5 volt busses on edge conn C. If you look at the schematic, BR2 is a test point but BP2 goes to the anode end of the 5.7 volt zener that sets the crowbar voltage (its cathode is connected to +5) and through a 10 ohm resistor to the crowbar SCR gate with 100 ohms to ground. This makes *no* sense because that connection shorts out the zener, so as soon as the +5 comes up, 100/110 of the +5 is applied to the SCR gate, so naturally it fires! A close look at the G8018 provided the answer. There is half a finger etched on BP2 which is also fully connected to BR2. (See picture) Looks like a drafting mistake to me. The Douglas extender board has sufficient depth in its female connectors that the partial finger of BP2 made contact and caused the crowbar to trigger as described. Cutting the "web" between the fingers fixed the problem. Naturally the intermittent flicker is gone for now, and I doubt it was an "almost" connection to the SCR gate because once it fires, the +5 should drop to near zero and trip the breaker, which has not been the case (except with the extender card). But at least I have the regulator on the extender card so I can start measuring when it comes back! http://s1181.photobucket.com/user/DrCharlesMorris/media/PDP-8/P09-26-15_20.…

I haven't used SQLite in an embedded environment yet. I wonder if it tends to thrash certain areas of the data file (which would cause flash wear problems). I appreciate the data point... And yes, SQLite was not intended for a high-volume multi-access environment, and my experience is definitely from embedded up through low multi-user local network applications. I'm sure there are many good reasons why MySQL has become the standard for web server applications. I originally understood - perhaps erroneously - that this was to be a smallish, local application, and for me (and the smallish types of systems I tend to build), I'd prefer to avoid the headache of administering the MySQL subsystem. But I stand by my statements about the separate, non-editable keys... :-) ~~ Mark Moulding

Video tour of 1985 home automation system

by sellam＠vintagetech.com

I wanted to share this because it's pretty neat: https://www.youtube.com/watch?v=0BHIknNa6Eg It's a ~6 minute tour of a home automation system from the 1980s that features graphical floor layouts and touch screen programming. The system is built into the house. -- Sellam ibn Abraham VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap.

DEC BA11K Fan repair

by lyokoboy0＠gmail.com

I have a BA11K power supply out of a pdp 11/34 that has frozen up fans. They are frozen up pretty bad. I heard from another list member here they are repairable, any advice on how to do so? --Devin
