I want to make my own modem cable for my Amiga 1000 computer. Could anyone send me the necessary pin connections to do this, or tell me where I could find out how to do it? Thank you. -- % Alan W.

Good for you! >Could >anyone send me the necessary pin connections to do this, or tell me >where I could find out how to do it? First, you should get a good book on RS232 to know what pins do what. Most technial bookstores sell such manuals. Then, get out your dusty _Introduction_to_Amiga_ book that came with your A1000, and use pages 7-11 and 7-12 as a guide to what pins on the Amiga's seiral port are normal and which are abnormal. Don't connect anything to pins 14, 21, or 23 (unless you know what you're doing). Good luck! ...tad

I want to extend my external disk drive cable but I wonder how long I can make the thing without degrading performance in any way. Has anybody out there tried this? I want to do it so I can program with my A500 on my lap, the way I used to do with my 1000. Also, I have a monitor that has an cable coming right out of the back of it. The cable goes into an IBM CGA card. The RGB port on the AMIGA seems to have the pins I need (R,G,B,I, Horiz, Vert, GND). I want to make a cable to be able to use this monitor. Has anyone tried this. I took the monitor cable connector apart last night and discovered that the RGBI pins were all soldered together with resisters between them ... but each had its own wire running into the cable (all but Intensity I think). What is the longest I should make the monitor cable? Finally ... where the heck (in CANADA hopefully) can I get DB23 connecters? Everyone tells me that only C= makes them. I say they are full of BS. ---------------------------------- Alan W.

I took --Stuff Deleted-- Maybe this isn't what you want to hear but why not yank the keyboard out of the plastic frame and make a simple 7 (8,9?) wire extension cable to hook the keyboard to the A-500 ?? *OR* if you have the extra bucks lying around for projects like this see if a B-2000 keyboard will work with it, sounds much cleaner :-) Seems to me that this would be much more preferable to slinking numerous cables down the side of your desk whilst you type (I've got 11 cables running out of this da*n thing !!). The keyboard is a simple (probably ascii) converter that takes a keystroke and translates it into a parallel converted word. As such it is merely laid into the A-500 frame with a small cable (only one) that hooks it to the motherboard. I've been toying with this idea myself :-) -- ------------------ // -----------Cut-Here---------------------------------- Erick Parsons // Words for the wise: *If it works don't fix it.* Sacramento Ca // mail to: ...pacbell!sactoh0!americ!erk ------------- \\// --------------------------------------------------------

Alan,
I don't know how far you could extend your AMIGA external drive
cable without degradation. If it goes by the standards of RS232C,
you could get away with 50 feet or so! I believe it would be safe to
assume that a distance of 10 or 15 feet would be reasonable if you
needed that much. As far as DB23 connectors go, I may be able to help.
In Dayton, Ohio we have an annual event called HamVention where a lot
of HAM radio operators meet and have a large swap meet. They also enjoy
computers as well. There were 3 dealers set up this year that had DB23
connectors. Here are the addresses and phone numbers of the three. I
don't work for any of them, I am just providing information.
CNE
305 University Blvd
Glassboro, NewJersey 08028
(609) 881-6779
"D" Connectors
23 Pin Female .65/each .575/each quantity ten or more
23 Pin Male .75/each .625/each quantity ten or more
"D" Connectors with hood
DB23 Female 3.50/each
DB23 Male 3.00/each
LTRON
8245 Brookside Rd.
Elkins Park, PA 19117
(215) 671-1613
(215) 924-4000
Prices about the same as "CNE"
Bill Barrick
13 Lafayette Drive
Phoenixville, PA 19460
(215) 933-0369
Again prices about the same as "CNE"
I know the prices for "CNE" only because I have their catalog. Hope
this helps you and anyone else out that needs DB23 connectors for their
AMIGA.
