I also have a photo copy of the manuals that came with my Gator (the manuals went to Dave as part of a halfsies deal to get mine cheaper). So I can make more copies easily with them if anyone needs a set (now I can drop them on the sheet feeder and walk away.. it was this first set that was a dog as I had to turn the page, press the copy button, repeat for 3 somewhat decent sized manuals). -chris <http://www.mythtech.net>

And I know Chris has the version that goes into a Cabletron (?) network hub, as a module. Ever start that up Chris? And sounds like my situation. There's admin passwords on mine. Haven't had a chance to hack them yet. I should try that out soon. Granted, none of my home network is set up right now... You can get software to reflash the firmware, using a Mac on it's console port. That should eliminate the passwords for you. Cayman, which is now part of Netopia, used to have their software on the website, but I can't find it now. Looks like Netopia dumped it. I have the files around here somewhere. As for documentation, I found... http://opcenter.cso.uiuc.edu/nas//nash/mac/gbox.html I also found this page just now in the WayBack machine... http://web.archive.org/web/19970705033723/www.cayman.com/gx.html http://web.archive.org/web/19970705034344/www.cayman.com/specs.html Let me know if you need more assistance. -- --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- (203) 432-0953 --- ICQ # - 905818 Mac OS X 10.1 - Darwin Kernel Version 5 Running since 01/22/2002 without a crash

It varies from amchine to machine. Everything in Forth is a word. A word can be as short as : or longer. These words have actions. Some expect a string, as in : expects a name and ." expect a string. Words that start with . are usually some kind of print. The sequence: 4 . will print the number 4. Here is another fun definition: : .H BASE @ SWAP HEX U. BASE ! ; DECIMAL 45 .H Disk I/O on fig Forth was block I/O. To access the first block: 0 BLOCK ( returns the address of the buffer, usually 1K ) If you type: UPDATE FLUSH it will write the buffer back to the disk. You could modify the data by: 55 0 BLOCK ! UPDATE FLUSH Not a good idea to try until you know what damage is done. The site I just sent does have some tutorials but remember there were several standards. Most are similar but some will be different enough to cause troubles. Examples: 2 NOT will return different values for fig and F89. I forget which but one will be 0 and the other will be FFFD hex or -3. One complements the flag and the other complements the bits. A good book to find is called "Starting Forth" by Leo Brodie.

Bulk Tape Eraser: Revisited

by Lee.Davison＠merlincommunications.com

or maybe I just have to unplug it rather than switch it off When you turn it off, and leave it in Line mode, and have an audio feed to the Line such as from a VCR, you can hear the audio real silently coming thru it, so there is a good chance the on/off button only does a standby mode. With there still being sound this seems likely. If the magnetism is strong it may take two weeks of switching off overnight to visibly reduce it and once or twice a week after that to keep it gone.

[CCTECH] any ISIS info out there?

by dpeschel＠eskimo.com

Since I've been curious about ISIS for some time, I was glad to finally borrow a copy of the _ISIS-II System User's Guide_. Comparing ISIS to CP/M is quite instructive. I already knew that CP/M has a few design flaws which ISIS lacks. On the other hand, I was surprised at how much memory ISIS takes up. And ISIS has its own design flaws (things are fatal errors that might be recoverable in CP/M, disk formatting can be quite complicated). Does anyone have details on the monitor, ICE80 (simulator), UPM (PROM programmer), or PLM80? I have seen the System/360 version of PL/M but I didn't realize it ran _on_ the 8080. (The manual implies that it does.) Having a system that can develop its own software is important, I would say. (Yes, Tony, we already talked about the front panel and monitor on one of the Intellec systems, but I think this hardware/software is different.) -- Derek _______________________________________________ cctech mailing list cctech(a)classiccmp.org http://www.classiccmp.org/mailman/listinfo/cctech

Looking for manual: Network Systems Corporation's Network Security Router

by foo＠siconic.com

I'm looking for the manuals for Network Systems Corporation "Security Router". I am most interested in the section describing the Packet Control Facility (PCF). I need the edition published prior to 10/1994 (most likely edition 1.0 or 2.0). Possible bounty ($$$) involved ;) Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

It only has six commands total (IIRC) Then again, it supports submit files, conditional execution and return codes. Primitive but more potential power than the early DOS.
