Anyone have a current e-mail address for Steve Loboyko?

by ethan.dicks＠gmail.com

Hi, All, Last week, I intercepted a 1970s Remex paper tape reader from a CNC mill that was on its way to the scrappers. It resembles this one: http://juliepalooza.8m.com/sl/remex.htm I wanted to look at Steve Loboyko's code for his PIC serial adapter and my attempt to download his link to his source was denied by his ISP (due to the .asm extension). I wrote him at the address in the GIF file he embedded in the page and my message bounced. Does anyone have a current address for Steve Loboyko or happen to have already downloaded his file remex.asm and could send it to me? My plan is to examine the code, look for pitfalls, and see what it would take to implement a similar scheme on an AVR chip since that's what I have in abundance. It looks like a fairly simple handshake and perhaps a bitwise data inversion then byte-wise serial transmission, but I'd rather peek over someone's shoulder and see what they did, given the chance. Thanks, -ethan

1984 ad (was re: Steve Jobs -2011)

IBM was > more interested in being Apple than Apple was, and I found a > better audience in Armonk than I did in Cupertino. I certainly never was an Apple employee unlike others here. It's interesting that Apple was away from Jobs from 1985 till 1996 and how this overlaps some of the dates others write, or I have implied in the past. The 1985 to 1996 period certainly had a lot of solid incremental advances in the Mac. The PowerBook and System 7 certainly blew away anything available on a PC-clone at the time. But at the same time there were NeXT's popping up in offices around me too.... :-) Tim.

space bar needed for LA30

by legalize＠xmission.com

Does anyone (Paul?) happen to have a spare space bar for the LA30? Is the spacebar used on the LA36 a suitable replacement? -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

Running 110V PDP-11 in a 220V world

by toby＠pdp11.co.uk

I've just got hold of a pair of PDP-11/35s that have 110V power supplies. What is the collectives view on the best way of running these in the UK? Is it safe to use a step down transformer (one of these for example: http://www.ebay.co.uk/itm/3-3-KVA-SITE-TRANSFORMER-110-VOLT-110V-UK-SUPPLY-…) or can I change the setup of the PSU to work from 220V? Many thanks, Toby

Fuji Eagle Bearing Replacement

by tshoppa＠wmata.com

> Has anyone attempted to do so or has disassembled the disk enclosure? > I would like to know if the heads are parked on or off the disks. I've taken apart HDA's from crashed Eagles, with no hope of ever putting back together. The heads are parked in the landing zones on the disk. An Eagle is a little more complicated than a "typlcal" drive in that each surface has two heads - one covers the inner half, the other covers the outer half. I don't think this head arrangement is unique to the Eagle but it's not all that common. At least one of the bearings (the bottom one) is in fact out of the HDA isn't it? On the top center of the HDA there's some sort of cover plate and I bet the top bearing is underneath it. Some might count that as "inside the HDA" but I count it as "on the outside and secured by a cover plate". Not that I've ever done a bearing replacement on an HDA quite like this. On removable pack drives, sure (RL01/02, RK05, etc) but obviously the pack was out :-). I would think you could locate a working HDA without a lot of difficulty.

Linguistic debate, was: Re: Sr. Server Engineer (Vintage Systems) etc

by jonas＠otter.se

Since this thread has gone completely off at a tangent, how about this: Shouldn't the sentence "They were an HP9866 printer, an HP71 and an HP82165 GPIO unit, and an home-made interface" be "They were an HP9866 printer, an HP71 and an HP82165 GPIO unit, and *a* home-made interface " and similarly "a 'Oxford comma' " should be "*an* 'Oxford comma' " ? (since "HP" is pronounced "aitch-pee" (beginning with a vowel sound) and "home-made" begins with a consonant sound). Seriously though, I agree with Tony that sometimes minute details of punctuation, quoting etc can be extremely significant. I spent four years writing installation instructions for Unix software for Ericsson, and during the review of every document, such details were always taken extremely seriously, since it was intended that the reader of the document should be able to reproduce every command exactly as intended, otherwise the installation would fail, or be done incorrectly. Obviously a Unix command line is very sensitive to dots, spaces, upper/lower case etc. Another aspect which I think is important is that documentation which contains spelling errors, bad grammar, bad translations etc reflects badly on a product which may be excellent otherwise. If you can't be bothered to produce correctly spelt, grammatically correct documentation, what is to say that the product itself is any better? /Jonas On Thu, 6 Oct 2011 21:11:03 +0100 (BST), ard at p850ug1.demon.co.uk (Tony Duell) wrote: > The text 'I used 3 devices at my HPCC demonstration this year.
