Any interest in two Apple IIc's, Apple monitors, Apple printer?

by kevin_anderson_dbq＠yahoo.com

Years ago my older son was given two Apple IIc computers, a small Apple monochrome monitor, an Apple color monitor, and an Apple ImageWriter II printer, all original to that era. There are also some miscellaneous diskettes. As far as I know this all works. I am getting the house ready to sale and a move, and don't need to store these anymore. Any interest from someone close to Dubuque, Iowa? If so, name a price for the lot and we talk. Kevin Anderson Dubuque, Iowa

Century Data T2000 exerciser

by nasim786＠earthlink.net

Hi, This is a belated response to a post you made here: http://www.classiccmp.org/pipermail/cctech/2003-February/010641.html I happened upon it while doing a 'for fun' search on the net for anything doing with good ol' Century Data, my employer when I was young. Couldn't resist responding to the post, even if it was half a year late! The exerciser that you have is/was for the Trident series of hard disk drives (predecessor to the Marksman). I was the main (in fact, pretty much the ONLY) technician at Century Data/Calcomp, for these exercisers back from the late 1970's to the mid 1980's, when they were phased out. I retired in 1985. Have fun! (BTW, where'd you find one of these dinosaurs??) Take care, Nasim

homebrew PDP-11 using ancient USSR chip

by bigral＠hotmail.com

Hello All, I wonder if anyone here want to try create tiny PDP-11 compatible computer using KM1801VM1B CPU. This chip still available in small quantities. The system could use an microcontroller such as ATmega1284 and/or big CPLD to emulate all required peripherals. There were many systems using this chip, but unfortunately most of them contains enough gold to became firstclass target for gold scrap hunters. Here is related link: http://en.wikipedia.org/wiki/1801_series_CPU Thanks, Andrey

Well. I remember the KIM-1 from the pages of _Popular Electronics_, and even handled one in a class on computational linguistics (not yet called that) with Victor Yngve at UChicago. Victor was the creator of a programming language called COMIT, which he was still teaching in the 1970s long after SNOBOL and even Icon had come along, but a heck of a nice guy. I had no idea that they had anything to do with Commodore.

PDP 11/04 in BA11-K Chassis

by jaquinn2001＠gmail.com

>Wow, that system looks practically spotless! And is that a LaserBus >machine to the left of it, in the first picture? Looks like a VAX 7000 >or AlphaServer 8400 chassis from the rear. Yes it is the VAX case but I don't recall the model. ?This photo was taken a few years back when the PDP11 was part of an exhibition at a museum here in Auckland. ?None of the gear was operational and I am not really sure how complete it was. > >And maybe the very corner of a VT52 at the far right? > It is indead a VT52. ?It didn't come with the PDP11 but I am trying to locate it. It would be a nice companion. The first rehabilitation step begins this weekend with the power supply being removed and tested. Regards Andrew

Back to my Ohio Scientific Challenger 1P

by jon＠jonworld.com

Vintage Computer Buds, I dug out some cables and hooked up my Challenger 1P to my TV. Instead of hooking the video directly to the TV like I did before, I hooked it through a Magnavox Modulator that rebroadcasted the video signal on channel three. This worked for some reason. Well, kind of. The URL is to a photo of what displayed on the TV. It wasn't too easy to read, but it is clearly some kind of ASCII character dump. No clue what's going on. Do I need to invest in a proper old-style modulator like they used on the Atari 2600 that will "split" the A/V signal from a single RCA cable and then put it on channel 3? Per the website, [ http://www.old-computers.com/museum/computer.asp?st=1&c=813 ] that looks to be the case... Here's the output I do have. What the heck is my machine doing? http://imgur.com/UWcZ8 -- -Jon Jonathan Katz, Indianapolis, IN.
