Any idea about what I could do with such a beast? I know that it would be wasted on me - I would be unable to push it at all - but I will keep it until someone who can really use it shows up, and I might as well see if I can put it to some use in the meantime. I gather it runs unix, so could I use it as an internet server for some rather high-demand applications? It seems a bit sad to accept the computer when I can't really use it, but I would much rather that than to see it scrapped. Adam.

Atari 8-bit Find

by foxnhare＠goldrush.com

Yesterday after several long weeks of lackluster thrifing I came across a 'complete' Atari XE game system. (though I have been avoiding that Atari ST at the other thrift store for weeks as I just don't have the room for it and whatever else it may need.) Of course, as many thrift stores do, they broke up the system down into several 'parts' and I dutifully browsed through the store and re-collected it. (for those unfamiliar with thrift store procedure, they bag the computer as one item, the disks as another, the drive as yet another, the power supply seperate, cables separate also, etc.) Remember if you find a hint of something you are collecting at a thrift, look around for other components (i.e. if you find a Commodore IEEE-488 cable start looking for PET/B-128 drives, printers, computers, tapes, disks, manuals, etc.) Among the items I got: XE game unit (equiv to Atari 65XE) with keyboard & Power Pack SIO & TV cables 1030 Modem 1050 Drive & Power Supply Atari Light Gun Several Cartridge games (including Bug Hunt which uses the gun) 2 packages of assorted hand-labeled disks for the Atari Several packages of orignal games, (mostiy SSI combat simulations, but all with complete instructions and very good condition boxes) I passed on the Atari Sticks as I have better than the 'Atari standard joystick' to use with it. Everything seems to be working great (except for loose video and audio jacks, but that is easily fixed) Now I am finally able to really play with the Atari disk drive more as I found a wealth of disk-based software to experiment with (BASIC programs and ROM dumps). The only thing I didn't get was a power supply for the modem, if I can't find one around the house I know just where to get one for a couple bucks. Then I can start transferring some of the Atari stuff from the internet to Atari disk. People keep saying how great the Atari 8-bit was/is, but when it comes to interfacing on a base system it is pretty limited... You can't do much communication without an 850 or a modem (I know some of you are going to talk about APE or some other PC to atari converter, but I don't have a PC...) The Commodore 8-bits are WAY easier to interface/communicate to anything.

publishing notes/hints

by mallison＠konnections.com

Just a thought To Whom It Concerns: Since I'm a publisher with a pretty good set up here for both paper and electronic publishing. I'd like to offer anyone who desires such services as creation of PDF files, typesetting, editing or organizing any documents to contact me. I can usually do most straight forward things like create PDF from ascii text in a couple of minutes. Editing, formatting, whathave you, takes more time. I'm not interested in charging for this, unless you are trying to make some money on a project and need an editor/publisher. Regardless, I don't mind helping out. If you need a hand with anything, please contact me through the list or personally at: mallison(a)konnections.com We've started a web page for documents that's still in its infancy at: http://www.konnections.com/bebooks/catalog.htm Our goal is to put every living available document there... might be ambitious. I'll be happy to post documents there as a service if you need a place. Thanks, -Mike Allison

FREE Disk Drive!

by kyrrin2＠wizards.net

OK, here we go. LOCAL PICKUP ONLY in Kent, WA (near Seattle). There's no flaming way I'm shipping this thing unless someone wants to pay the freight up front. ;-) What I've got is a Century Data M315-1 SMD disk drive. 14" platters, God only knows what capacity it is. It seems to power up and spin up OK, is noisy as blazes, has a HUGE linear voice-coil head positioner, and that's about all I know (or want to know) about it. I'll happily hand this beast, along with its rack mounting rails, over to the first happy vic... uhh, 'volunteer' to speak up and say they'll come get it. Any takers? If not, and I can't get any from comp.sys.dec, I'll have no choice but to tear out the useful parts and scrap the rest. Drop me a note, please. I hate to scrap anything, but I need the room! I'd far rather give the beast to someone who can use it. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin2(a)wizards.net) http://www.wizards.net/technoid "Our science can only describe an object, event, or living thing in our own human terms.

BBC Model B - video help

by adavie＠mad.scientist.com

I have just retreived a BBC computer. Seems to work fine, and I have managed to get directories of several of the (rather warped) 5.25 disks. I'm extremely surprised any data is readable at all - nice looking tandem dual floppy. However, onscreen I see there's a problem with the machine. I see perhaps 1/5th of the screen and then it repeats. Furthermore, the width of the screen isn't correct... that is, I see 20 or so character wide lines displaying and thus staircaising. I suspect its a hardware problem (almost 100% certain here, I've tried software mode changes - same in every mode), but have nil hardware expertise. So, when (occasionally) i see a > prompt, and type, i see what I type perhaps 20 times in varying places on the screen, each line offset from the other. Can anyone suggest my first steps to playing with it - what sort of chips should I be looking for, perhaps? I know, I'm behind the 8-ball, but you're all such brilliant guys at restoration, right?

This sounds like it is some multiple of the desired (for the monitor) rate. That's what's getting the multiple images across the width of the screen. Also (maybe first, but definitely in conjunction with the above) look for 'Vertical' frequency/lock. This one is what is getting you multiple images in the vertical direction. Memory says that the adjustment is "roll down (image) and just return the adjustment the other direction till it locks in place." The 'horizontal lock' is a much courser adjustment. (This is all standard TV/Monitor adjustment stuff. If anyone has any specific advice different from this, by all means, give it a try.)

Apple //gs boot problem

by rcini＠email.msn.com

I finally got a working SCSI card for my Apple //gs, but I now have a problem booting off of the hard drive. Here's the setup. CMS SCSI card to Miniscribe 20mb hard drive (old Mac SE drive). GS/OS 6.0.1 diskettes used to setup the hard drive. All files copied to hard drive with no errors; files are visible and runable from GS/OS. Turning off the machine and turning it back on produces a "Check startup device" error. Booting with the "no harddrive" GS/OS diskette works fine. All required files are on the hard drive. It's almost like a boot block is not written to the drive. For installation instructions, I culled info from Nathan Mate's Apple // web site. Any clues?? I installed GS/OS multiple times with the same results. Thanks! Rich Cini/WUGNET <nospam_rcini(a)msn.com> (remove nospam_ to use) ClubWin!

Diablo 1340 terminal?

by rws＠ais.net

Hi all- Tonight I got a Diablo 1340 hardcopy terminal. It looks like a table with a Diablo 1550 typewriter on top of it, but the typewriter is part of the table. Inside the large black box under the table are power supplies, cardcages, fans, etc. It works, except for one thing: whether in local or remote, whenever the 1550 gets a carriage return, it rams the home hard stop and the ALARM and PRINTER CHECK lights go on. I press ALARM to reset it and it works fine until the next carriage return. I tried adjusting the home stop in and out (it's actually a stiff spring-loaded stop) with no luck. When the terminal is first powered on and it seeks home (slowly) it does fine, without hitting the stop. Any ideas? (BTW this thing is just jam-packed with 7400 series logic and a couple of chips I can't identify. It was built in 1974 and installed in May 1975- I even got the maintenance record with this thing. It's serial no. 769.) Richard Schauer rws(a)ais.net
