    It doesn't look IBM to me. It's neither an SMS card nor an SLT card, and the board colour and handle doesn't look like IBM style. IBM core planes...

    Applied Technology had a range of S-100 cards so I'd say it was a 6800 CPU card. I have a junked AT SC/MP CPU S100 card they designed but don't think...

PDP-Lifter

Racking an old PDP-11 or its peripherals can take some care, owing to the weight and bulk. The task can be made easier with this simple equipment lifting cart you can build. You can quickly, easily and accurately rack, unrack and move heavy gear with confidence - and possibly save your back as well.

DECals

by 1944GPW on September 29th, 2016 at 07:05 AM
A few months ago I experimented with some do-it-yourself decal material I'd bought at a scale model exhibition.
I'd bought two types of the special paper, one type was the traditional waterslide decal paper in which the image is printed normally as you would look at it, then cut out, dipped in tepid water for 30 seconds and carefully
slid off onto the receiving surface. This type is the same as you have in a model kit. The other type of decal paper is for printing a reverse image,

IBM I/O Selectric terminal interface for a microcomputer, circa 1980

by 1944GPW on December 22nd, 2015 at 08:23 PM
Back in the late 70s early 80s Dad brought home an IBM I/O Selectric terminal - probably a 2741 or MT/ST I/O Writer, I don't recall - that we planned to use as the terminal for our Fairchild/Mostek F8 development kit board that Dad imported from the USA in 1978. A few of dad's IBM colleagues were also 'into' the F8 and, being the old-school engineers they were, came up with this circuit design.

Sadly we didn't build it, so I can't tell you if it works. At the time we kids were more

A good-enough replica of the ''digital' PDP11 masthead for the H960 rack

by 1944GPW on July 8th, 2015 at 08:20 PM
I recently lucked onto not one but a pair of original DEC H960 racks recently, after searching for a few years. They were interstate but I found a backloader who agreed to move them at a fair price, if I didn't mind waiting a few weeks. Now they've arrived I've thought they would look pretty nice with a pair of those groovy 1970s magenta and pink 'digital' mastheads. But they are pretty much unobtainium these days and even the plain two-tone ones with no labelling list for up to $200 USD.

Some projects I'm dabbling with.

by 1944GPW on July 8th, 2015 at 07:34 PM
G'day,
I thought I'd have a go at seeing if the VCF blog capability would be of any use. I have a few projects I'm working on (don't we all) and this might be a good way to keep my meanderings in one place, rather than have them disappear off as old threads on various forums. I have a bunch of other hobbies outside of old computers so I'm not sure how often I'll update things, but this placemarker blog post is a start.

Things I'd perhaps like to cover are:
  • an IBM System/360
