At Connector Substitute

It describes how you can build your own appletalk compatible network connector using only two or three condensers. Very easy, very cheap and works like a charm. -------------------------- CUT HERE ----------------------------------- Here is the info on CapNet By Nate Hawthorn (Mr. 6502) 7/20/90 Updated 8/21/90 Please upload this to other systems! It's under 15K, and takes less than a minute to upload at 2400 baud. INCLUDE THIS TEXT when uploading & describing the file: If you have a Mac, you have AppleTalk ! (it's built in) You can set up a VERY good and low cost network without buying much. (You know, the kind IBM'ers pay big bucks for). This is a text file containing instructions and a schematic (yes in a text file) on how to make this low cost AppleTalk connector. CapNet costs about $1 a node! You can build two in about 1/2 hour. Apple sells their's for $80 ea., even with the cheaper Phone Net connectors, it will still cost you $40 to set up two nodes. Please upload this to other systems, it's under 15K If you are on AOL, see "News ideas and resources" section of "Communications & Networks" section for more usefull information. Originals are kept on the Space Sciences BBS and America On Line, SSci BBS's number is (805) 259-6407 (end upload description text) The challenge here was to make a schematic that anyone could read without needing any drawing programs to read it. Also to keep it within the 65 character limit some systems have and include spaces for blank lines (this could be a first). The schematic is included in this text! CapNet is a simple low cost network for AppleTalk. CapNet was designed because network connectors are too simple to cost so much. You can spend $20 to $70 for each connector, and you need at least two. That's min $40! You could have a nice couple of nights out for that! CapNet was designed for small local networks of up to 10 nodes (further testing may up that number). I have tested it to about 400 ft ! (and it still looks good on the scope) CapNet costs about $1 in parts (depending on what you may have on hand and what swap meet you go to). Two connectors can be assembled in about a 1/2 hour. It's so simple and cheap that you'll never see it retailed. CapNet has a few limitations; You must use CapNet only where the GROUNDS of all the computers are the same (within reason). Like a single office, building or home. It is not designed to connect to the other office across the street, or your neighbor's house. (it doesn't actually use the ground, and is isolated) There is built in protection that can isolate you from possible damage. WARNING: YOU WILL ONLY BE TOLD THIS ONCE... DO NOT USE THIS IF YOU ARE RUNNING IT TO OTHER BUILDIN…
