amber CRTs
by Herb Johnson 30 Mar '19

30 Mar '19

Someone is asking me for a particular oddball-brand 12" CRT monitor, for one of those "word processors". I'm posting here, because I have one for them but they want it cheaper than my price. (No, it's not CGA or VGA or MGA etc.) But this monitor is *amber* (yellow phosphor) and that's how I value it, as a CRT part. If I have to buy such a CRT "cold", it's likely I'd have to spend $75 to get it. It will likely fit a number of terminals or vintage computers. (I know how to do that.) So: does someone have a 12" amber CRT or monitor for sale? Then I can offer this guy what he wants a little cheaper. and I'm curious, do my vintage friends particularly *value* amber monitors (versus white and common-enough green) anymore? Is it still a thing? Herb "screen-burn" Johnson -- Herbert R. Johnson, New Jersey in the USA http://www.retrotechnology.com OR .net

Straight 8 training
by David Gesswein 29 Mar '19

29 Mar '19

Hopefully at this workshop I will finish the work to get rid of the last known issues that prevented fully using the straight 8. If any of the Docent's or anyone else wishes to practice/try using it stop by. Sunday would be better since most of the repairs should be done by then..

Is a Sun E250 something that VCF would want? Have one from a friend that passed away. Also have an Oracle N|C, Oracle's set top forray into cloud before cloud I guess you would call it. - Ethan

F/S: Sun E450 (not mine, not VCF's)
by Evan Koblentz 28 Mar '19

DO NOT REPLY TO THIS LIST, the seller isn't here. Seller said he's in Monroe, NJ. His email is below. -------- Forwarded Message -------- Subject: RE: Consignment at VCF East Date: Thu, 28 Mar 2019 19:12:52 +0000 From: Steve Zubatkin <zubykins(a)outlook.com> To: Evan Koblentz <evan(a)vcfed.org> Hi Evan, Thanks for the response. Here’s information on the condition as well as its specs and accessories. *Condition:* Overall condition is 9 out of 10. Externally, the system looks new except for some minor scratches. As with most E450s, the removal media/control panel door does not latch but this one doesn't open by itself. The system is 100% functional as it passed all diagnostics, connects to the network and runs Solaris 10 from hard disk. This is a “turn key” system: 1. Sun Ultra Enterprise 450 on 4 casters 2. Power cable 3. Console Serial cable for connection to a PC 4. 2 Keys for locking the power switch and door accessing the disk drives 5. A notebook containing hardware documentation 6. Solaris 10 This E450 is well configured: * 4 X UltraSPARC-II 400 MHz * 4,096 MB (at the maximum) * 2 x 9 GB & 5x 18 GB Hard Disks. All disks have been wiped. * System originally had a CD-ROM drive but it was upgraded to DVD * DDS3 Tape drive * Diskette drive * 3 power supplies * Sun Quad Gigaswift Ethernet UTP Adapter Thanks, Steve

DIP switches
by Mike Loewen 28 Mar '19

28 Mar '19

Don't neglect them while troubleshooting, especially the little red bastards. :-) My HP 2647A graphics terminal developed what appeared to be a sync problem when displaying more than one line of text. Swapping the suspect cards with known good ones from another terminal didn't change a thing. All self-tests passed, including text RAM and graphics RAM. Graphics mode worked perfectly. I finally swapped the two RAM cards (32K on each), changing the DIP switch configurations on each. At last, a RAM error. I excercised all of the DIP switches, put everything back together and it worked. This is the second time I've had problems with DIP switches in vintage HP gear. The other was in a 2117F I was working on for Dave McGuire. Same cure. Mike Loewen mloewen(a)cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/

The two things I am most interested in working on are: 1. I have a Mac SE Superdrive. It doesn't want to boot correctly and I get an image of a disk with a question mark when I turn it on. One time I used a Desktop Diagnostic disk and I was able to get into the computer. It suggested there was damage to the hard drive and asked me if I wanted to re-initialize (?) and I said no as I wanted to see what was on the computer. That was a mistake because since then the same diagnostic disk will not do anything. A "Macintosh Basic" introductory disk also works on it but I can never get to the desktop screen. It's been frustrating for sure. 2. Trying to get one of my Commodore 64's to work with sound. I don't know if the only way you can do it is to buy the correct chip (the 6581?). I've never replaced something like this... I think it doesn't need soldering but I'm not sure and I'm hesitant to buy the chip if that isn't the solution or there is a better work around. David K.
