Hello all, we got a nice squary blue tele-tec terminal but the screen is covered with a lot of spots in the silicone between the safetyglass and the tube. is there a way to fix that? -- Met vriendelijke Groet, Simon Claessen drukknop.nl

Lear Siegler ADM-5

by dave＠willomail.co.uk

Hi Folks! Another terminal question. I have an ADM-5 here which works fine but when switched off, the display colpases into a very bright vertical line and then to a single point in the center of the screen. This then lasts for about 10 seconds and always happens regardless of the brightness setting. Question is, is this normal and if not, is it likely to damage the phosphor over time? Cheers, Dave

Using an 8" drive on a PC (WAS RE: "Smartcom II" package available)

by earl＠baugh.org

You may want to try to find a copy of the presentation Malcolm gave at VCF East 9.1 (see : http://www.vintage.org/2014/east/session.php#218) It's actually on-line at : http://www.avitech.com.au/disk-imaging/disk-imaging-vcfe-2014.pdf It had lots of good details and info on a system that he set up and demonstrated at the session.

FWIW I also have an unpopulated 4-slot control unit for the display-only version; considering the size and weight I expect they'll both end up being recycled some day although I may keep the display 'just in case'... m

Available: Two DECServer 200's

by chuck.mcmanis＠gmail.com

These were the terminal servers of their day. Nice way to hook up to a lot of vintage machines with equally vintage hardware :-) I'd be happy to take these down to the FedEx store and ship them to somewhere. My experience with that before is that its about $30 pretty much anywhere in the lower 48 states of the US. --Chuck

I do singularly cosset the TD-700, having used one briefly, attached to a B6700, however a quite frustrating terminal to use due to the limited line-length of 32 characters - only 8-lines vertically could be tolerated, but the limited line-length on machines that have sequence number fields beyond column 72 meant horizontal scrolling was essential and frequently needed. Still, the SELF-SCAN red display and de-coupled layout (screen+keyboard+control unit all separate) heralded future-times, so it was an iconic object just not practical. I make the count of 4 existent TD-700s, that is pretty good for such an unusual terminal.

Recent Downtime of Bitsavers & Manx

by jwest＠dewey.classiccmp.org

Greetings folks. My sincere apologies for the "unannounced downtime" for manx a few days ago. The downtime was to install a new 33TB NAS, which will allow us to at least double the disk space available to manx (and other classiccmp-hosted sites). You're welcome Richard. Jay West PS - you may see "that is what you get for free", all I see is the $$$ I just spent on a 33TB NAS. Again, you're welcome.

Value of a Tantalum Capacitor

by jnc＠mercury.lcs.mit.edu

> I can't tell its value, the markings are 224 E5Z on one side and 038 > ASF on the other side. > .. can anyone tell me what value/spec the capacitor has? Err, was that maybe "Z5E"? I have found this page: http://wiki.xtronics.com/index.php/Capacitor_Codes very helpful in deciphering capacitor markings. Noel

Does anyone have any information on this item? It is a single-slot 16KW core memory module for a PDP 8/E,M,F. A manual would be helpful; schematics would be great. Thanks, Jack

Using an 8" drive on a PC

by jnc＠mercury.lcs.mit.edu

> From: Chris Osborn > I don't have a nice editor on the PC. Epsilon. ("Wasau.") Basically EMACS (although the default key-bindings for the more esoteric functions are not the same - easy to fix, though). Been using it for 25 years or so; fast as all getout, totally customizable in something that's so close to C that anyone who knows C can pick it up in about 3 minutes. Can't recommend it highly enough. Noel
