Canon BX-1 (1977) Manuals
Recently, I’ve started working on a Canon BX-1 machine dated 1977. It was CANON's first standalone business / home computer featuring I guess the Motorola MC6809 CPU, one line of gas plasma display a thermal printer and 125k floppy drive. See pictures here: https://drive.google.com/open?id=1rT4qwtiR68AN5DRqoCwjxGDJvRRdlHha In working condition but without manuals or disks. Only little can be found for this machine, its not listed in http://www.bitsavers.org/pdf/ nor https://amaus.net/static/S100/ Also http://archive.computerhistory.org/ isn't mentioning the machine. So I would be happy, if anyone can help in disk images or manual scans (manual front pages are shown in the picture link above) regards Thomas Known CANON BX-1 Disk/Documents Disks: MCX OPERATING SYS.

Panasonic Electronic Filing System - document scanner storage on MO disks
Hello, all - Has anyone run across the subject system - a mid-90s Motorola '030-based document scanner/retrieval system? KV-F520 seems to be a model of the unit, along with LF-7300A or LF-7304 5-1/4" MO drives. I have a hold of some media that I can read, and can see the moral equivalent of files in Panasonic's own format - I suspect it's thinly veiled TIFF or maybe a capture format of their own making. Has anyone else run across this before? - David

DEC Pro 350
Well, I bought that DEC Pro 350 on ebay. It initially booted up and I got the error screen. The error code I found on the Internet was related to the hard disk controller. So, I thought I just needed someone to sell/give me some systems disks for the unit and I could try to setup the drive again if it still functioned. Then, it after a couple of restarts (I re-seated the boards and cleaned the connectors) it stopped showing the error screen (with picture of the computer). All the diagnostic lights are red on the back and nothing ever shows on the screen. The power comes on and then nothing. If anyone has any thoughts, I would appreciate it. I knew the history of this type of computer and figured it was a long shot. I am just disappointed to have gotten really nowhere with it. Thanks! Kurt

ARPANET Reaches the Royal Signals and Radar Establishment (RSRE, Malvern)
The following extract comes from a History of Programming Languages (HOPL) retrospective on the development of the Ada programming language written by the individual who was the government lead at DARPA for much of the time of its development (Colonel William A. Whitaker). I found it humorous. Perhaps you will too. - The ARPANET connection was inaugurated during a visit to RSRE by Her Royal Highness Queen Elizabeth II. Her Majesty sent a message of greetings to the members of the HOLWG from her net account, EIIR, by pressing a red velvet Royal carriage return. Because the address list was long, it took about 45 seconds for the confirmation to come back, 45 seconds of dead air. Prince Philip remarked, joking respectfully, that it looked like she broke it. - I suspect that we've "all been there" at one time or another! paul

Re: ibm panel
Well done, tasteful. I was very lucky with who ever scrapped that 360/50 and took the hinge and frame along with the panel.

Which aspects do you consider the DMV to be competent in? Is a 1983 car really "historic ~> vintage"?? I can't tell them apart since the 1970s! Yes, I can tell the difference between the bumpers of 1973 Honda V 1974, but only because i was working on them. In the 1960s, there were some more interesting cars: The Honda S800 (not imported to USA) was a 2 seater sports car that was a poor man'd Ferrari - a design exercise that got out of hand and went into production, with dual OHC, roller bearing, (even distributor shaft), 9.5K (conservatively) redline. Meanwhile, the Toyota 800 was a very similar body with barely more than a lawn mower engine. When competing, the question was whether the race would be long enough to be decided by speed or DNF. Does something like that count? NO! long time ago, some claimed that the definition for this list (a claim rejected by list management) was "ten years". Today, I might agree with 27 years, but next year I would want an increment. Although I consider PC to be fun, I'm not sure that I could agree with calling it "vintage". If John Titor is around, I will supply a 5100 (APL AND BASIC) and a good investment portfolio in exchange for ONE-WAY back 55 years. Payment arranged after arrival. I'll take the long way part-way home. -- Grumpy Ol' Fred ci...@xenosoft.com

ISO: Tektronix 4404 peripherals
Hi all -- I'm working on fixing up a Tektronix 4404 workstation (runs Smalltalk-80!). Or rather, I'm trying to collect the needed parts to assemble a complete system so that I might fix up said system -- at the moment I have only the main CPU unit (but hey, it's a good starting point). I am looking for: - Keyboard (Tektronix P/N 119-1872-00) - Mouse (Logitech P7-3F-TX-19-1808-00). This is likely a standard 3-button quadrature mouse but if I can find the exact match, so much the better... - Mass Storage (Tektronix model 4944, possibly others? This is a SCSI device containing a hard drive on a SCSI->MFM bridge and 5.25" floppy drive on a custom SCSI->floppy interface.) If anyone happens to have spares or knows anyone who might, please let me know. Thanks as always! - Josh

Re: What is vintage (was: Why don't you respect the mail threads?!)
When the list was formed, it was defined as 20 years. Of course now, the list itself is over 20 years old. Sigh ... well if we're really have this conversation I maintain that the present definition of "vintage", or at least how we see it over at Vintage Computer Federation, is no longer year-based. The proof: Windows 98. :) Obviously the * majority * of vintage computing is the sweet spot that we all know and love -- 1960s, 1970s, 1980s. But just as a modern car can become an instant collectible -- think Dodge Viper, original Ford Taurus, etc., which were groundbreaking designs -- so too must we all as collectors keep in mind that not everything old is worth saving, and not everything worth saving is old.
Re: DEC Pro 350
Thanks for the suggestions. Interestingly, upon first boot I was able to get the hard disk controller error with the picture of the computer. Then, sure subsequent reboots failed to display anything. I removed all the cards and booted with no luck. It looks like I will need to build a cable to try terminal mode. I did hook a vt220 with a 9to25 cablw, but didn't get anything. Since successful booting is intermittent, probably a heat or power problem. I will continue to try to get terminal mode working.
