›     This took a considerable amount of effort for me to go back into my notes to type this information. After an amount of time went by I forgot some stuff so had to figure it all out again.›     I also have some notes not yet neatly types out, of my DTMF tone decoder/encoder, and transiever PLL chip control (added scanning functions and direct frequency access to a CB radio). I put those 2 items above with some other gadgets I thought up, and used the 4 joystick ports of My Atari 800 as a half duplex Phone patch/Repeater. And I know someone else that used the 8-Bit Interface for a controller of a Voice Messaging Service and is accually making money charging people for there message box!›     If your really interested in this stuff I may be able to make it understandable but there would be alot of work on my part to make it presentable. If you have no electronics background or the equipment the I would say the other stuff is beyond the scope of your capabilities...››     Any questions can be directed to me VIA these 2 following BBS systems:›››Outter Limits BBS (617)665-0977, account handle: Gumby››Argus Computerized Exchange (617)674-2345, account handle: Ricky››Internet E-Mail Address: gumby@ace.com›› NOTES: This text was entered using TextPro so you can reformat the text for printer if you desire and still be able to view with a 40 Column ATASCII viewer...››  PORTCNFG.TXT - Explains how to set-up port for output/input using basic examples.››  8BITINTR.TXT - Almost a full-blow 8-bit interface (IEEE-488).
