Paging 'John B' alias 'danielbradatanu'

> Has _anyone_ heard from John? He hasn't replied to my last three emails and > his eBay activity stopped around the first week of May. > > Bill I bought from (them) 13&23-March and recieved both items on 4-May. There were some problems with a core memory board that was shipped in a (padded) envelope and arrived crushed. They replaced the whole item. General positive feeling though they ahould be encouraged to wrap things better. Note that the 5 1/2 week span is a long one. Communications were from one "Heather" B. John A.

At a different time the said same history channel said it was the VT fuse... I suspect a broader view would say many things did have significance to the outcome and duration of the war. No one development was alone in winning the war. Allison

DEC power control? How do it know?

by cmcmanis＠mcmanis.com

Ok, I'm cobbling together a PDP-11 and I ran out of slots on my BA11 so I put a bus extender into it and plugged that into a BA23. The system works fine (thank you micronotes!) but I'd like to figure out how I could set it up so that powering up the 11 powered up both the BA11 and the BA23. Now I know the little 3 plug do-hickey (I think it is a mate-n-lock) normally connects to a power sequencer in the rack, but I don't have one of those. Is there any way to make it work otherwise? --Chuck

Tektronix 4014 HV PSU

by rdd＠smart.net

A while back, when I turned on the power to my Tektronix 4014 terminal, nothing appeared on the screen, but I smelled an acrid odor. Upon closer examination, the smell came from the terminal's HV PSU board around the HV transformer for the CRT circuitry. Is this a common problem with these terminals? I'm hoping that the CRT hasn't shorted out, but I haven't had a chance to check that yet. -- R. D. Davis rdd(a)perqlogic.com http://www.perqlogic.com/rdd 410-744-4900

Compu-Das (Random Factors) S-100 A/D converter board

by rdd＠smart.net

While checking out the contents of some 8" floppies on my PDP-11/73, I spotted a couple of circuit boards sitting on top of my LA-120 (that reminds me, I've got to get another box of greenbar... hopefully Office Depot still stocks it; can you believe that I've had quite a few co-workers who had no idea what greenbar paper is?). One of these boards is an S-100 bus board, a Compu-Das model 696-33 made by Random Factors, Inc. of Durango, Colorado. The board is partially populated by chips (it came out of a repackaged Dynabyte 5200 system made by a company Computermotor Corp.), two of which are a Burr Brown ADC76KG A/D converter, and another Burr Brown chip: an SHC80KP (not sure what this one is), in addition to various TTL logic. What's interesting about this circuit board is that the chips are all socketed in little copper sockets made into the blue circuit board, and, apparently, to add D/A functionality to this board as well, one just plugs in some (or all?) of the missing chips. Does anyone know anything about this board? -- R. D. Davis rdd(a)perqlogic.com http://www.perqlogic.com/rdd 410-744-4900

No, but you can easily see it in any sensible editor (my definition of "sensible" has always included the ability to show binary or at least control characters :-))... > I must admit that I find files containing printable text information > mixed up with binary data to be _very_ annoying unless there's a good > reason for doing it. > > If you must use some kind of markup language, at least encode the data as > strings of hex digits, or base-64 encoding or something like that. I don't have any objection to that, in fact I'm inclined to agree, but I felt others don't want to take up more space than necessary. If encoded, I'd go for base64. It's the most efficient of the common schemes (hex, uuencoded, base64), has none of the ambiguities of uuencode (there are some very broken uu..code implementations around, because it's not fully specified), and if anyone does want to read it manually, a decoder is only a few lines of <language of choice>. On the other hand, hex has some advantages: easy to read, very easy to {en,de}code, and it would be more appropriate, perhaps, for binary values in tags (assuming the values weren't just written in ASCII in the first place). -- Pete Peter Turnbull Dept. of Computer Science University of York
