I have two Decwriter III's that were taken out of service in January. They were working when turned off. They are not light weight. I will send them to anyone who wants them for $10 each plus shipping. The $10 is to find a box/pallet and haul them to the shipping office. Anybody can have them for free if they want to pick them up. The other option is I donate them to the computer surplus. Mike mmcfadden(a)cmh.edu

Q-bus (was Re: Wirin' up blinkenlights)

A DMA cycle can take forever so you could build > > nope, it will bus timout on you. Boy did we find that out the hard way. The Software Results Q-Board was built back in the days of the MicroVAX-I and MicroPDP-11. The designers picked some time (by tapping off of a stage on a divide-by-N counter) to timeout while waiting for a DMA cycle. It was well outside the Q-bus spec of the day. This board worked in MicroVAX-II and -III designs with no complaint. Eventually, someone wanted to stick a Q-Board in a VAX 4000 with a TLZ04 interface. By the time this machine came out, the Q-bus was no longer implemented in the way it once was. Certain cards were no longer "in spec". The upshot of this was that the TLZ04 interface could grab the bus longer than the Q-Board would wait. The fix was to redesign the bus timeout circuit (a cut and a jump and a new PAL) because DEC sure wasn't going to change their interface to work in an older Qbus box. It took us quite a while to find this one because our board didn't change and there were no problems in 99% of the VAX 4000s out there. It was a piggy controller. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

OT: Re: In defense of NASA

by mtapley＠swri.edu

R. D. et al, (* Disclaimer: I'm full time on a NASA project, the IMAGE mission, though my direct employer is Southwest Research Institute in San Antonio, Texas, who does a lot of commercial space work as well as NASA. My views are mine alone, however, and do not represent company policy nor that of NASA. *) ... so you know which side my bread's buttered on, and by the way if you are a taxpayer, I thank you very much for your support and hope you feel that you get your money's worth out of IMAGE (http://pluto.space.swri.edu/IMAGE/) (you can see data on some of the links referenced there). I've worked hard to make it so. > Has the space program had any positive influence on >spirituality and humanity's relationship with Nature? Yes. Remember the photo of the Earth, taken by the returning Apollo mission? Or Earthrise over the moon? That's a perspective that could never have been achieved without manned spaceflight. (I say manned, because no machine would have been programmed to look in the right direction at the right time, and notice the incredible aesthetic impact of that image, and capture it.) Its value is of course subjective - but there's a generation grown now that *knows*, because they've seen it, that Earth is just a big blue marble and not the entire universe. For better or worse, it's a finite planet. Is the ozone hole a big deal? Maybe, maybe not; but we would never have known about it - because we would never have noticed it - without the *global* data that could only be provided by satellite observations. What about global warming? We might have picked that up in 10 or 15 years from temperature measurements at land stations, or maybe not. In any case, it would have taken more years for global climate modelers to convince everyone else that the land data they had, plus limited sea-surface measurements from ships, really did amount to a significant change. Global sea-surface temperature measurements, collected by satellites, provided that insight to us about a quarter of a century earlier than we would otherwise have had it. Same notation for El Nino. Whether we take advantage of the data we have, and do smart things with it, is an open question, but we would not even have the options, in those cases, without spaceflight. There are similar arguments for land-use patterns, deforestation, pollution (airborne and water-borne) plumes, etc etc etc. Not that the data *could* not be collected without spacecraft - but that it would have been a lot harder and more expensive and in most cases *would* not have been done. We know our terrestrial problems better because of space activities. Communications satellites carry WWF, so maybe I shouldn't bring those up, .... oh heck yes I should. Living in North America, I can watch NHK news live broadcasts from Japan (for example). Is that a cultural benefit? You bet. I can see, and hear (and heck, maybe one day even understand) what's being thought and done about problems I don't even have (earthquakes? volcanoes? not in Texas), half a big blue marble away. Cultures I would never know existed are as close as a twist of a knob. Sure, some of that could be done with undersea lines - but not as soon and not as cheaply as with a satellite link. As for the Columbus argument ... I'm always nervous about that one. For me as a born Texan, descended of Germand and English settlers, heck yeah it was great that Isabella hocked her jewelry to pay for that expedition. As a Spaniard, I'd probably be a bit less enthusiastic; I mean looking at Spain now, it didn't do them much good in the long term. As a native American, I'd be pretty bummed about it - why didn't the silly Europeans stay over there and pave Europe? Depends on your perspective. But what I do think Spain bought for Columbus' trip, and was cheap at the price, and what I think NASA has bought for us and was *incredibly* cheap at the price, is potential. We know we *can* build solar power satellites and beam microwave energy to Earth to supply electricity for our classic computers :-) without contributing (as much) to global warming. We know we can put long-term facilities in low Earth orbit for medical reasons or biomedical research or crystallography or whatever. We know we can put people on the Moon and bring them home intact. We know we can go to Mars and colonize it, if we choose to. Those options are expensive, and some of them may not be worth it - it's a choice we have to make. But the fact that we *have* the choice is worth a lot to us as a nation, or as a species. - Mark

It's a small room and has the heating off and the two adjacent rooms have the heating turned way down. There's usually a machine in the garage on 24/7 in the winter; if ever it's not on, there's a heater and/or dehumidifier there to protect the tools and 'puters. > OTOH, most of that heat comes from 1 21" monitor, and the real problem is > the design of this house.

Mine's the same: upper floor, centre room, just at the top of the stairs, seems to collect all the heat from downstairs -- and has a 20" Sony GDM1961/VRT-19HA. -- Pete Peter Turnbull Dept. of Computer Science University of York

I haven't run a heater in winter for quite some time. I have a small electric/ceramic heater in the bedroom because it's difficult to move the heat that far away from the machine room. But I only need that on the coldest of days. None of those are really my "classic" machines but I figured it'd fit. :) -Dave McGuire

It belonged to the local AT&T group here in Orlando FL (as an asset tag), and is apparently the only survivor of three that fed Usenet into the Central Florida area. It works fine, boots without problem, and includes a console terminal, keyboard, user books, and a number of tapes. One of those is said to be a bootable tape with a complete backup. Sixteen megs ram, two 120 meg SCSI drives, 5.25" floppy and tape drives. It does not have an net card, though: that died and was removed before I got it, nor does it have any disks. I don't have any time to devote to the poor thing, it looks all forlorn sitting in the corner, and I'd really like to see it go to someone who has the time to get the thing running. Obviously, due to the size and weight, I can not ship it, but it is here to be picked up in east Orange County, Fla, pretty much anytime. If you are close by in a surrounding county, I would be willing to bring it to you. If interested, <mailto:mflang@bellsouth.net> or <mailto:qillerpenguin@hotmail.com> and we'll arrange pickup/drop off. Max. (ps: during the last week of June and first week of July, I will be in the Davenport (Scott County) area of Iowa, and if someone in the surrounding area is interested in it, let me know, as I'd also be willing to bring it for delivery.) -- All parts should go together without forcing...
