Apple IIC+ Pointers on getting programs to and from machine.

Also there are instructions for a cable you need. I think there's a freeware program called ADT (Apple Disk Transfer?) which does the job with the standard Apple serial card. When I was looking, there were two versions for two different cards. The only card I had at the time was a software bit-bashed card which was not supported and ran at a max of 300bps (perhaps 1200) - obviously that was not going to cut it, so I built my own card (not a standard apple card either :-( ... And wrote simple programs on each end to transfer the images - worked very well.

Canon BJIF-3020 serial board users manual?

by dwight.elvey＠amd.com

Hi I assume you already have a serial light/breakout box. One can't even begin to deal with serial without one. I know that Heathkit would do nasty things like invert the status of handshake lines, for their printers.

3M Tape Drive on eBay

Thought this was interesting for no other reason than it was manufactured under the original name of 3M (Minnesota Mining & Manufacturing). Didn't know they made computer gear. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1247&item=4125760894& rd=1

LAPC-1 Cards

by squirechris＠softhome.net

Hey I just found this post; what are the odds your friend still has a LAPC-1 card? Thanks. - - - - MPU-401/LAPC-1 Hans Franke cctech(a)classiccmp.org Thu Jan 9 12:52:45 2003 Previous message: MPU-401 Next message: H89, REMark, Sextant Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] I just taked to my friend. The cards are LAPC-1s. He still has two new units, and he'd be willing to part for 40 Euro each (~42 USD), plus shipping. So if someone still wants to build a early 90s game PC, just drop me a note.

Slightly OT: Ethics

True, and there's another factor: SGI's licence for the software on those CDs prohibits them being passed on to another person except when transferred with a machine licensed to use them. SGI have occasionally been known to get shirty about that. > What am I supposed to do if it becomes obvious I am not going to be able to > track the guy down?

This was an honest mistake. I realised that from your post. I'd suggest that you take reasonable steps to track down the owner, and if that fails, keep them. If the owner were really desperate to have them back, he'd probably have contacted you (assuming *he* has *your* contact info). Anyway, you might need them yourself, if you get an SGI machine without CDs (like the Octane you mentioned elsewhere). -- Pete Peter Turnbull Network Manager University of York

I can't find any actual figures on Kodak's website. The figure I used is one I saw in a couple of places on the web, and in some old notes (see LP Clerc, Photography: Theory & Practice, sec.349). I used to be really into photography, and about 30 years ago, and I did a 3-year HND course which included a lot of theory. I've seen references to about 1/10th or even 1/20th of that in various places, too. That seems too low, but there could be several reasons for that. Firstly, it used to be the case that only Kodak would process Kodachrome -- one of the reasons professionals used to use it only for special purposes, preferring Ektachrome because it could be processed locally (and therefore quicker, and with "adjustments"). That's no longer the case, but I don't know if Kodak have changed the process (quite likely) or just made it available to other processors. I do know that professionals could get a different service from Kodak than normal users (because I could, via the college I studied at) and that could make a big difference to the results. We used to reckon a 35mm Kodachrome slide roughly comparable to a 6x6cm Ektachrome. Not that Ektachrome's at all poor: want a good colour print? Take an Ektachrome slide and make a Cibachrome print. Except I don't think you can get Cibachrome any more. The low figures I've seen for Kodachrome have been on pages where it's compared to other colour films, and I think they're suspect, because I don't think they're the result of optimal (or even close) conditions. I'd be prepared to believe that 2000 lines/mm is a theoretical figure based on grain size. If so, that won't be the true figure for a real exposure in a real camera, so I'd take it with a pinch of salt. A "good" lens on a 35mm camera typically has a resolving power no better than 150-200 lines/mm (ref LP Clerc again, and MJ Langford, Advanced Photography). -- Pete Peter Turnbull Network Manager University of York

Looking at the source for parts of gphoto suggests that's common, so I wouldn't be at all surprised to find it's the norm, even for higher-end cameras. If you were a camera manufacturer, and your competitors claimed 1.3Mpixels, would you be more honest and claim 0.4? But I don't actually know. -- Pete Peter Turnbull Network Manager University of York
