So, what's the deal with DigiBarn?

by COURYHOUSE＠aol.com

I wrote them with an Osborne question as we got a osborne 1 but it was later and slicker and they replied other than that I do not know. Seems we are getting hit with computers with handles on them this month. A RS 4P showed up today! Ed Sharpe archivist for SMECC In a message dated 8/24/2015 3:30:06 P.M.

Their website hasn't seen a proper update in years, and it looks like they have a lot of choice hardware donated to them that they may not be maintaining... Is it open to the public? Are people actively volunteering there to make sure this stuff is shown some love and not falling into disrepair? Keeping leaky batteries, capacitors, rust at bay, and doing repairs? Imaging disks? They have some very worthwhile examples of machines but I haven't seen much >from them as an organization in years! I'm sure lots of people would be willing to help if they are under-resourced.

De-yellowing

by evan＠snarc.net

Going to be de-yellowing a //e Platinum this weekend. Check out this picture of the top cover. You can see the non-yellowed part on bottom. Big difference! I'll post "after" pictures. http://snarc.net/yellowing.jpg

De-yellowing

by COURYHOUSE＠aol.com

and I will add... the Retrobrite... we are not sure what the long term effect is.... It would be a real bummer if 50 years from now the object decomposes.... OH NOOOO!!!!

That is what the Air and Space Museum has done for a while - a very thin wax coat covers the original, untouched finish, and a new paint job is applied onto the wax. Apparently it is easy to strip off, thus a reversible portion of a restoration, but I think the paint is not durable at all (which is why you should not touch things in museums unless given permission). I am not a fan of the Retrobrite process, although I have never tried it out. In my mind it just seems wrong. -- Will

Looking for some shipping help with a M33 teletype

by rdawson16＠hotmail.com

I posted this about a week or so ago. I bought a teletype in Elkorn, Wisconsin and need a volunteer to help with the shipping; Take it off the pedestal; Put the shipping bolt in the printer; Watch craters and freighters, that they have plenty of foam to cushion the unit. I will pay you for this service... Thanks, Randy Dawson

VMS7.3 dismount of a device with pagefile before shutdown?

by holm＠freibergnet.de

Hi, I've managed to relaocate the pagefile.sys of my VMS7.3 to the secondary disk disk1$dia1 because of space considerations of the first disk (380MB total, free blocks 228672 now). I've seen complaints of the system that the disk wasn't properly dismounted after each reboot and would be rebuild. A hint from my friend Vaxman was, to mount the disk with the option /NOREBUILD in SYPAGSWPFILES.COM so it looks like this now: $ MOUNT/SYSTEM/NOASSIST/NOREBUILD DISK1$DIA1: DATA1 $ RUN SYS$SYSTEM:SYSGEN INSTALL DISK1$DIA1:[SYSEXE]PAGEFILE1.SYS/PAGEFILE EXIT $ EXIT Is there an other way to properly dismount the drive at the shutdown? My home directory lives on the 2nd disk too..and I think /NOREBUILD supresses the warning message, but not the problem at all.. Regards, Holm -- Technik Service u.

Sign magnitude, one's complement, two's complement

by spc＠conman.org

For my own morbid curiosity, and because it came up on another mailing list I'm on [1], what machines commercially avaialble were sign magnitude and one's complement? Every machine I've encountered was two's complement (okay, IEEE 754 [2] is a sign magnitude format but I'm talking about integer implementations here, not floating point). I've only found reference to one sign magnitude computer (the IBM 7090, release in 1959) and a few one's complement machines (mostly the PDP series from DEC). Where there others? And honestly, are there any machines that use anything other than two's complement today? -spc [1] http://lua-users.org/lists/lua-l/2015-08/msg00386.html [2] AKA floating point.

Indianapolis: More classic computing equipment than I can shake a stick at.

by maxxtw＠gmail.com

Anyone who's passing through, or lives near Indianapolis, feel free to give me a shout to set up a time to peruse what I have. I have amassed enough machines to take on their own gravitational pull. Most are in various states of disrepair, in need of attention, but quite a few still work or don't need much work to be functional. A number of machines I intend on keeping for their "neat" factor (like an Olivetti M20) but might be persuaded to part with. Apple (bunch of IIc's, IIe's, IIgs's) Macintosh (40 or so compact Macs - 512, Plus, SE, 'splodey-battery-SE/30's -, a big 'ol stack of 68k and PPC desktops, PowerBooks, a stack of DuoDock II's) Kaypro (maybe 6?) Osborne Compaq Portables (luggable and plasma) Epson QX-10 (2 machines, 1 monitor, pretty certain I have the Valdocs disk somewhere) IBM (5150's, 5160's, and a 5170 with box, and a few monitors) Wang (PC S1-2 with keyboard/monitor(s)) Franklin 8000 with keyboard A few 386/486 machines ADM 3A terminal (doesn't power on, but it's cute) Amiga 2000HD (boots, but I don't have a keyboard or mouse, and the floppy drives continuously seek) Amiga 500 (untested, no power supply) C64's (definitely for parts!) and some drives Tandy 1000 EX (untested) NeXT 21" Color Monitor (too huge and heavy for me to keep, I'll be happy with a VGA converter when I find one) And probably a few other things I'm forgetting about. Price-wise, basically make me an offer. Scrap metal prices are fine with me for a lot of machines so long as they're not actually getting scrapped (hence the post here!). If you're looking for something specific, let me know and I'll see what I have. Thanks! Kind regards, -Maxx
