I turned on my VT220 for the first time in nearly a year. The screen says "VT220 Keyboard Error 4", all four green LED's (on the top right of the keyboard) stay lit, and nothing appears on the screen when I type. Disconnecting and reconnecting the coiled-cord between the keyboard and the terminal causes a cursor block to appear on the screen, but the keyboard is still locked and the LEDs stay on. Power-cycling the terminal shows the same error message. However, the boot prompts from the 11/23+ are displayed normally, so the receive part of the terminal at least is working. Where should I start looking, before replacing the keyboard? thanks for any hints -Charles

Compaq Portable II flat CMOS battery

by gordonjcp＠gjcp.net

Before I go hauling all those little Torx screws out (yes Tony I *do* have proper Torx bits, unlike the last person to be inside it), can anyone point me in the direction of the CMOS battery? I bet it's right underneath the monitor, or something. Gordon

IBM RS/6000 Help / advice wanted

by john_a_s2004＠hotmail.com

Hi, Thanks for the encouraging responses, I'll go and have a read. Someone also kindly emailed me these URLs with further useful info: http://www.pimpworks.org/ibm/aixled.html http://www.pimpworks.org/ibm/ledcomm.txt I have contact with a AIX CD, and I have obtained (a few!) SCSI CD drive that cn be tweaked to the correct sector size. Couple more questions though: 1. Is there a back-up battery (perhaps in a RTC chip like on a Sparcstation 2), that will have surely failed by 2008. 2. Is there a source to download diagnostic floppy set, I hadn't known about these until today. Thanks again, John _________________________________________________________________ Discover Bird's Eye View now with Multimap from Live Search http://clk.atdmt.com/UKM/go/111354026/direct/01/

IMSAI 8080 on eBay

by michaelgreen42＠comcast.net

You are probably right. Its not like I'm trying to hide anything but I really don't know much about these. Other than the fact that it powers up that's about it. Picked it up local with the idea of "wow IMSAI" but realized it's a bit out of my realm of interest, I'll never actually use it, and I need the money to go to school this Fall. I'm more than happy to answer any questions anyone has though. -------------------------------------------------------- Message: 1 Date: Fri, 19 Sep 2008 13:03:19 -0500 From: "js at cimmeri.com" <js at cimmeri.com> Subject: re: IMSAI 8080 on eBay To: cctech at classiccmp.org Message-ID: <48D3E967.2020104 at cimmeri.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed >From: "Mike" <michaelgreen42 at comcast.net> >Subject: IMSAI 8080 on eBay >To: <cctech at classiccmp.org> >Message-ID: <7CA2A42621B44381A42EB354A4390329 at pal> >Content-Type: text/plain; charset="us-ascii" > >I've decided to sell my IMSAI 8080.

choppers

by dgriffi＠cs.csubak.edu

I stumbled on a disturbing thing on Ebay. There's a guy who seems to specialize in taking apart perfectly good classic computer stuff to sell the pieces. I found him when looking for a VT100. He's selling a naked CRT that he says was taken from a working VT180. I asked him why. No answer. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

Toshiba T1000 manuals

by dgriffi＠cs.csubak.edu

I seem to recall someone asking for manuals for the Toshiba T1000. I have the user and tech manuals on Ebay now (item 230296780064). If you're not on speaking terms with Ebay, email me privately. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Morrow MicroDecision 3 project computer

by dgriffi＠cs.csubak.edu

I have a Morrow MicroDecision 3 that won't post and I'm not interested in restoring it myself. The case is in fair condition with some cracks to the front. I have at least fifteen MD3 motherboards in storage. What I'm offering is this nonworking computer and a couple motherboards marked "good" by whoever put them in the box I found them in -- all this for cost of shipping. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

LED displays (TIL305, TIL308, etc.)

If you look for "bezel" in electronics catalogs you'll see both grey and red filters... but that's a good way to pay a lot of money for ten cents of plexiglass :-). The Rohm-Haas color code for the red transluscent plexiglass you want is #2423, it's fairly common at real plastics supply houses. Now finding good plastics retail shops that'll sell or even give away small scraps today is not as easy as 20 years ago... a 4x8 sheet of this stuff is pretty huge for TIL305's! Shops that make and sell signs might have some small pieces for you. Tim.
