ADM3a parts at System Source March Workshop...
by Herbert Johnson 08 Mar '24

> Mounting hardware - these mounting "ears" and band were taken from a > Ball CRT with a broken neck. Could be used to mount a different CRT in > an ADM3a. Just a caution on that band - *do not remove band from an intact CRT*. That metal band provides tension on the CRT against the vacuum inside versus 15 pounds per square inch air pressure outside. Yeah, 15 pounds per inch. If an un-banded intact CRT is struck and shatters, those glass shards could be propelled like a glass grenade. Most CRTs break at the neck, or the very tip at the neck. The neck is thin glass. That narrow opening slows and limits the airflow to *into* the CRT which otherwise has very thick glass. These CRTs were designed decades ago with safety in mind. A lot of small terminal and TV CRT's have a band and screw-mounts. There's no need to fuss with that band. Reattach some other kind of "ears" if needed for mounting in another TV or CRT. But I've taken TV CRTs and popped them right into ADM3A's using the same ears. regards, Herb Johnson -- Herbert R.

I just noticed that this is no longer available. I should have reserved it two days ago when I had the chance, but I hesitated. If anyone cancels and frees up a room, please let me know.

ADM3a parts at System Source March Workshop...
by William Sudbrink 08 Mar '24

08 Mar '24

Hi, I will be at the System Source Workshop on March 30,31. I will be bringing a bunch of ADM3a parts, including: (Names are to help identify pictures, web site below) Chassis1 - this blue chassis is an original, serial number 6961 with the 115 volt transformer. Chassis2 - this blue chassis is a type 2 (with the extra venting and cardboard interior), also 115 volts. Chassis3 - this brown chassis is a late type 2. It has no speaker (the speaker was soldered to the mainboard in late type 2). This is a 230 volt transformer unit. Its fuse holder and switch were donated to 115 volt machines a long time ago. Otherwise complete. Clean board - this mainboard has no keycaps but is otherwise physically complete and in good condition. It powers up to a cleared screen with a cursor but shows no activity on key presses. Note that the key switches are present on the board. Dirty board - this mainboard has seen better days. There is some light corrosion on some chip pins and component leads. It has some but not all keycaps. Definitely does not work as it stands. I got it this way and only took it for the lower case ROM which is being used elsewhere. Good monitor - well, good in that it works and has no visible burn in. But... it has terrible cataracts. It has not, fortunately, started leaking. Complete with driver board. Zenith monitor - Has a little screen burn and a couple of scrapes on the glass. I have no compatible driver board for this monitor. Mounting hardware - these mounting "ears" and band were taken from a Ball CRT with a broken neck. Could be used to mount a different CRT in an ADM3a. Driver1 - This is a complete driver board for a Ball CRT. Unfortunately, the anode cap was smashed, but I am including a replacement that will need to be installed. Driver2 - This CRT driver board is incomplete. It has had its HV transformer taken. I _think_ this is also for a Ball CRT but it is different from driver1. Could be useful for repairs. Bracket for mounting the HV transformer is included. Pictures at: http://wsudbrink.dyndns.org:8080/images/adm3a/ Finally I, of course, would like some money for this stuff but more importantly, I do not want to take any of it home with me! I will deal and if it gets late in the day and you're nice, you may take it home for free. Bill Sudbrink -- This email has been checked for viruses by Avast antivirus software. www.avast.com

Visual 50 terminal troubleshooting
by William Sudbrink 04 Mar '24

04 Mar '24

I have a Visual 50 terminal that I am now troubleshooting. I got it in the late 1980s and it worked fine until 1995. I can't find a good schematic for it or ROM images. Its symptom is that it powers up to continual beep (solid tone, not repeated beeps) with a cursor on the screen. This is not in the troubleshooting table of the manual that I have. I know the keyboard is capacitive foam pads. I was hoping that was the trouble, but it is not. I disassembled the keyboard and removed the old pads, replacing a few with some spares I had from SOL20 repairs. Has anyone corrected this problem before? I suspect that the EPROMs are going. Thanks, Bill Sudbrink -- This email has been checked for viruses by Avast antivirus software. www.avast.com

I'm not asking that anyone here can help, but do you know of forums that I can drop into to ask about the Rigol 'scope. I'm finding a lot of weird this (like the serial decode changes if you change the time base ???). -- Linux Home Automation Neil Cherry kd2zrq(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ
