Apple Lisa I/O board diodes

by witchy＠binarydinosaurs.co.uk

Hi folks, 'Decaying battery' panic led me to unearthing my Lisa 2/5 to check the state of the batteries on the I/O board since it hadn't been out of its box or powered up since 2005. Fortunately the damage is very minimal and is only restricted to track discolouration and external rotting of one particular diode which I can't find mention of on my schematics. Anyone with a 2/5 care to check their I/O board for me please? The diode is D8, just above the battery location. It's in the board in such a way as to make its markings pretty unreadable in the pictures I took before cleaning, but it's the only white diode in the machine and I'm guessing it might be a 5.6V 1N4734A based on what I can see. Fortunately it still works for now, 0.7V voltage drop. Pic of the board before cleaning is at http://www.binarydinosaurs.co.uk/LisaIOBoard.jpg Cheers! -- Adrian/Witchy Binary Dinosaurs creator/curator Www.binarydinosaurs.co.uk - the UK's biggest private home computer collection?

Rich and Jay this middle book in this url is the one we have here at museum the thin one Jay is sending you we have never owned. Is it uncommon or?? Yes by all means photo/scan the thing! https://www.flickr.com/photos/131070638 at N02/25092973706/in/photostream/ the 11/40 series books seem to be the ones we run into the most and I should round them all up from the various buildings and keep 2 sets and blow the others out for people to set next to their processors.

Problem with scanning those handbooks - it is a destructive process mashing them in a flat bed. Maybe using one of the hold the book and photo the pages works well? or.... find one that is blown apart already...

Non-binding-breaking Book scanners (Was: Looking for PDP handbook

by COURYHOUSE＠aol.com

well... the trick is to have book partially open not cracked and to have 2 cameras for fast production copy and uniform size on the size as cameras are fixed clear material flattens pages sure if just a page or so a camera even hand held works... but if you are humping pages all day long..... you need this thing!

...And when you look at the site you will see guy in dust mask. when scanning fungus ridden or moldy material a must although I prefer a class A respirator. We have an offsite storage we call the tombs and it smells like one... but it is for martial that is biohazzard challenged that we want to scan someday. too awesome to toss but too ucccky to have in the archive, museum area or library. If another copy shows up and/or someone scans a copy then the ucccky held copy is discarded. If not at least a copy is saved here and sometimes we suit up and scan some of it.

Yes, but, . . . I've participated in building a few similar devices. Instead of the two sides MEETING in a V, there should be an open area right at the spine to accomodate the greater thickness of the spine itself. Having the two side panels able to slide up and down, with pegs, a few inches would accomodate that and permit a varying amount of spine clearance. Lighting. Ideally, lighting for copy work should be at a 45 degree (1/4PI) angle. That way specular reflection (glare) from glass cover (still needed occasionally!) or even just glossy paper, is not going towards the camera. If the trough faces north/south, then that can be done with light(s) north and south of the unit. Using two lights makes it much easier to get acceptably even illumination. Some people prefer various forms of diffuse light, or coaxial lighting ("ring" light). Having the camera at a fixed position relative to the work holder is great IFF you are doing consistent size. Different sizes could be dealt with through variable focal length ("zoom") lenses, but that is not always the ideal solution. I like to use FLAT-FIELD lenses, which are generally fixed focal length (sometimes called "primary lenses"). Enlarger lenses are an extremely cheap source for those. Being able to move the camera/work distance closer/farther requires a movable mount to change distance, but keep the camera centered relative to the work. North/south motion can be easily handled by moving the book along the trough, preferably with a fence, or simple bench-dog stops. The other motion generally requires the camera mount to be a pole at a 45 degree (1/4PI radians) angle relative to the work. Since the work is at a 45 degree angle from vertical, that means that the pole can be VERTICAL, with the camera mount aimed at a 45 degree angle. The post should be offset slightly from the north/south center, with the movable camera mounts holding the cameras at 45 degree angle (preferably with the focal node close to that central plane). Positioning of the book would require placing it so that it is centered north/south (calibration marks, as well as fence or bench-dogs, are very helpful!) and moving the camera up and down and focussing for distance. NOTE: use of other than 90 degree (1/2 PI radians) for the book holder would require further changes! -- Grumpy Ol' Fred cisin at xenosoft.com

BDV11 'mis-feature'

by jnc＠mercury.lcs.mit.edu

So I recently discovered that the LTC feature on the BDV11 bootstrap board has a minor issue: the latch that stores the 'LTC enabled' bit is _not_ cleared by INIT (unlike every other PDP-11 device I've ever heard of), but only by a direct store into the LTC CSR, _or_ power cycling (BDCOK, to be exact). This means that once you turn the LTC on using the BDV11, neither an INIT instruction, nor a 'Start' command to ODT, will disable it! Needless to say, it tends to scramble the booting process when an LTC interrupt shows up before the software is ready for one... I _was_ going to ECO the board, to connect BINIT to the clear input of the latch, but... I now think I know why DEC did this. There is no bus receiver on BINIT! (And there is, alas, no empty DIP space I could put one in.) I'm seriously tempted to connect the 'reset' circuitry on the BDV11 to BINIT, instead of BDCOK. That would mean that hitting the reset switch on the BDV11 wouldn't emulate a power cycle any more, but maybe I could live with that - I never use that switch anyway. And it would be _so_ nice to have 'Start' disable the LTC... Noel
