I suspect not, and if not the topic does not belong here and is therefore regarded by many of us as spam. Dale H.

The life of Plastics

by rodsmallwood52＠btinternet.com

I just took my copy of RT11 mini reference (1985) off the shelf and the front cover fell off. Not through wear and tear but brittleness. I wonder what else is going to fall apart in the plastics line. Oh well at least I have the finest book cover repair material known to man to hand. What is it? Green packing tape! Rod

Interlan DEC Ethernet boards

by billdegnan＠gmail.com

Other threads about DEC and Ethernet got me thinking....I have a couple of QBUS LSI Internal BD-NI2010A Ethernet boards. Anyone using these to connect to an Ethernet network on their system? It appears the ethernet address # is burned/hard wired into the card. Mine come from the University of Delaware.

IBM 3511

by wdonzelli＠gmail.com

So today I picked up something I had never seen before - an IBM 3511. This is a large tower expansion chassis for the PS/2 line. It looks very straightforward - but can any of you PS/2 fans comment on this? Was it an unsuccessful product? Low demand item? -- Will

VAX-11/780 Board Set on eBait

by jnc＠mercury.lcs.mit.edu

> From: Devin Davison > well there goes my plan of trying to keep it under the radar. Sorry, I didn't mean to upset your plan (and you); I just didn't know if anyone was watching for VAX-11/780 parts, they come by so rarely. We have discussed this topic before, but let me recapitulate one point about pricing and valuations: if we want to stop this stuff being scrapped, we need to make sure the prices realized are well above scrap. This will have several consequences: i) If people only get low (scrap-region) prices, why go to all the bother/hassle of listing things on auction sites; just proceeed directly to 'Go'. ii) Hopefully, if values are non-trivial, the word will get around, and people who have this stuff will go to the effort to list it, instead of leaving it to moulder, etc. Yes, I understand that will make this a more expensive hobby, but TANSTAAFL. YMMV. Noel

Trying to repair a Smith-Corona letter quality "printer"

by fozztexx＠fozztexx.com

I picked up a Smith-Corona Memory Correct 400 Messenger typewriter at Goodwill last week. It has the daisy wheel but no ribbon. I debated getting it since I already have enough retro stuff around the house, but every single time I?m at a Goodwill I look at all the typewriters to see if they have some kind of serial or parallel port. This one has a DE9 connector on the back which can be connected to a computer using an external box called a Messenger Module, which I also have. I plugged it in at the store and the typewriter didn't power up. They gave me 10 bucks off so I couldn?t resist and bought it. I?m hoping it?s an easy fix, but I can?t figure out how to get the thing apart at all! The four screws in the bottom just hold the plastic case to the metal frame, and removing them didn?t allow the case to come apart. I can?t figure out how to get the two plastic halves separated. There's no screws in the top and no other screws in the bottom. The plastic halves aren't welded together around the outside, I can wedge a screwdriver between them all the way around. There seems to be something holding the halves together near the four corners. Does anyone have any idea of how to get this thing open (without breaking the plastic)? I?ve searched all over the internet but I can?t find any scanned service manuals. The typewriter is from 1984 and was sold for $600 new so it doesn't seem to me like it would be a "disposable" item so there has to be a way to open it and service it. From what I can tell the 200/300/400 all use the same case, and the Memory Correct II/III use a very similar case, so info for any of those may help. I posted an album here: http://imgur.com/a/SxfTE and a YouTube video here: http://youtu.be/ryDl0Qvl7Gk Any assistance in opening the case without breaking it will be greatly appreciated! :-) -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com
