Setting switches for a Vertex 150 possibly for a perq

by cz＠alembic.crystel.com

Hi! I'm trying to read possible Perq2 data off a 40mb Vertex V150 drive. Unfortunately the switches were scrambled and I can't seem to figure out which settings work. Does anyone have one that can check their switch settings? This doesn't seem to work: https://stason.org/TULARC/pc/hard-drives-hdd/vertex/V150-43MB-5-25-FH-MFM-S…

I know multiple people that have signed victims up to mailing lists -- many of which were questionable content -- as an attack on said victims. Pretending to send email from said victims to cause bounces and ire to be (mis)directed at them seems quite the same to me. Five years? Sure. Many people will create filters and simply ignore the messages. As such, it's effectively internet background radiation / wasted bits. > Whack-a-Mole works when everyone whacks their moles.

As far as I know, > no other email provider allows this. I've not seen anything in any provider's terms of service that say anything about what type of email they receive, save for exceedingly few categories; child porn and illegal activity among the short list. I have yet to see anybody state that sending an email to an invalid email address and (potentially) receiving a bounce is illegal. So, again, no grounds for Google to do anything. Feel free to try to get Google to change their terms of service. > I don't see how this relates to Google allowing their services to > be used to test my mail server (and likely thousands of others too) > numerous times over multiple years for being an open relay that could > be exploited to distribute spam. Are the messages /originating/ from Google / Gmail? Or are the messages /originating/ from somewhere else and causing the bounces to go to Google / Gmail? The former is something Google cares about. The latter quite likely is not. > If you burn a junk (snail) mail, could there be a security lapse in > your furnace that would cause it to be replicated into a thousand > copies of itself, run up your chimney and distribute itself into > thousands of your neighbours letterboxes?

Sadly, many companies leave a LOT to be desired when it comes to abuse handling, especially when the abuse originates from their organization.

Ouch, but 2 Perqs out.

by cz＠alembic.crystel.com

This was a long day. Went over to the house and started working on getting the Perqs out of the basement. I've been moving smaller stuff to make room and it was time. First up was a Perq1 chassis that just had the big disk drive in it, side and rear panels. I figured it was lightest and after taking off the sides and top was able to lift it and carry it up steps. Still heavy and bulky, but it made room and a path to get to the second one. The second one was a mess but a lot heavier: It still had the card cage in it and I was not going to be able to lift. So I figured out how to take the sides, top, front, back, and bottom (pounds are made of ounces) and then spottted the screws that hold the card cage and power supply in the box. Bless the people at perq, those two screws out and you can lift the cage out the side of the box. The card cage without cards (took them out to lighten) was heavy but I got it up the steps. Then with a herculean amount of effort I managed to carry the rest of the box up, followed by the sides, top, front, back, and bottom plates. There are still two more Perqs down there. They have heavier front plates (I was able to take them off) with real shielding. They were different designs, so they were not Perq1s and they are not the same as each other. Question: Are there any pictures of other types of Perqs? Unfortunately they are still buried under old Sun gear and a Vaxserver of some sort. So I'll have to think about those, but they will need to come apart as well. Question: Do the card cages and stuff come off the later Perqs as well? Also got two different types of keyboards that say Perq, and a monitor that looks like a big fat white Vetrex and says Three Rivers. Question: What does a Perq mouse look like? At least this stuff will not be junked. I'll take pictures and such tomorrow and throw a tarp over everything tonight because I'm too tired to get it out of the truck. I swore off high-mass hobbies for a reason....

Rod Coleman's personal history of founding, building & running SAGE

by boris＠summitclinic.com

Probably read about this machine in Byte back then but was programming PDP-11's. Was very disappointed in IBM PC as IMO was far inferior to PDP-11 which was was easier to interface to data acquisition hardware and had a much nicer instruction set. Ran into 68000 processor for first time in 1986 when my father bought a 512 K Mac and couldn't believe performance of this CPU compared to PDP-11 - 24 bit addressing! and inferior memory access to what Sage had. Also, found 68000 instruction set very similar to PDP-11 and had no trouble writing assembly code for it a few years later and also really liked Apple's debug switch which was best implementation of a debugging system I've thus far run into. Weird that Rod Coleman had 68000 instruction set associated with IBM 370 whereas to me it was very PDP-11 like and 24 bit addressing was a very nice feature (that was one similarity to IBM 360) Other interesting aspect to SAGE history was the influence of September 1966 issue of Scientific American computer issue on Rod Coleman and lots of other people I've talked to. Was so glad that had this issue to read in 1966 and spent most of my time in boring school classes designing logic circuits and then building them at home using discrete DTL logic with parts salvaged from surplus IBM boards. Thanks for the link as didn't realize 68000 was used for home systems before I ran into Mac. >This may be old news -- it was new to me, though. > >https://suddendisruption.blogspot.com/search/label/Booting%20Sage%20Computer > >I'm not really familiar with SAGE machines.

Winsystems SAT-V40

by doc＠vaxen.net

I know this is a long shot, but I'm asking anyhow. I'm looking for the Ops Manual for a Winsystems single-board system. Model: SAT-V40 P/N: 400-0186-000 The SAT-V41 model is essentially the same board, so I'd settle for docs for that. There are references (from 2012) to SAT-V41.PDF, so I know it at least *did* exist in digital form. If anyone in the US has the paper manual I would happily scan it, and pay postage both ways. Thanks! Doc

dp8340n IBM 3270 protocol transmitter encoder

by wh.sudbrink＠verizon.net

Hi, In cleaning up my lab and stores, I have discovered that I have a tube of 10 of these chips. I'm not quite sure what they are for or were used in (or even where I got them). Anyway, if they are, in fact, for managing 3270 mainframe terminal traffic, they're probably not of much use to me. I've also noticed that I'm getting very low in vintage 4000 series CMOS chips. Anybody want to trade? Bill S. -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

MM11-F manual/prints available

by jnc＠mercury.lcs.mit.edu

I finally got around to completing the processing of the scanned images of the pages of the MM11-F manual and engineering drawings. A PDF is available here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/DEC-11-HMFA-D_MM11-F_Manual.… http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/DEC-11-HMFA-D_MM11-F_Drawing… For those who object to PDF/A, here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/MM11-F_Manual.tar http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/dload/MM11-F_Drawings.tar are TARs of the original TIFFs. The images aren't that great, I see; the original paper copies aren't too hot, IIRC. If anyone actually has a use for these (does anyone out there _actually have_ an MM11-F?), and there's a problem, let me know, and once I get my scanner running again, I can try and get better ones. I thought we were missing the MM11-E manual, so since the two are so similar (most of the boards are the same) I thought the MM11-F's would mostly fill the gap, but it appears it's there, prepended to the MM11-E prints. One thing this set has which might be useful is the backplane wirelist (the MM11-E's seems to be missing); given the commonality of most of the boards >from the MM11-E to the MM11-F, they're probably very similar.
