Hi all,
I had ask what the PROM part number was for this IDer. With these older
IDers they are usually simple and programmed to give a string of 1s to
turn on tone and 0s to turn off a tone and the string is in the CW
sequence to give the ID and the PROM data bit is output to a tone
generator. There is often timing also to give the ID at some interval,
but if working this would not be a problem.
I bet if one had the known ID now in the PROM it could be figured out in
minutes for someone who has a prom programmer. I've done this for a
verity of ROM devices including trunking info, etc.
The only problem one often sees is the PROM is so old it is hard to
find.

Hi Chris,
I've you're offering to make the information available... please
send me a copy. I'd be willing to pay for photocopies and postage
no problem. If you've got page scans... even better and easier to
Email them to me as time allows. I still have a prom burner
available and would be able to do some chip programming as time
allows. If you have the prom map already figured out... easier for
me/us.
cheers,

A very long time ago I reversed engineered the CWID 70 stupid prom
thing and
made one with my call. I had the manual, a prom burner and a lot of
time to kill.It is a very similar design to the one in the 70's or
early 80's Amateur Radio
Handbook. I have
the manual somewhere if the Repeater-Builder folks want it for a
scan.

Hi David,
I was dealing with the "Manual" portion of your post first. Now let's
talk real world... Relative to other options most everyone will have
a fairly hard time trying to deal with obtaining replacment bipolar
(aka bi-polar) prom chips. It's simply not cost viable to support them
although I do know one prom based cw ider mfgr (Autocode) who still
support replacement proms ONLY for their products.
Some of the Repeater Builder Group members can provide bipolar proms,
programming, information and alternatives. There are a number of
after-market daughter board options to retrofit an Eprom into and
orignal prom location. You would need to locate a method to program
the replacment eprom. Probably the most practical option for most
people who want to keep the original circuit in operation.
I actually have a bipolar prom programmer but right now it's not
easily on-line operational, nor do I expect to place it back in
service for another few months. Sometime in the future I might be
happy to help you go the prom route but there are practical limits
when a replacement re-programmable cw id unit costs only about $25
delivered.
: Second, Repeater-builder site does not have any info on anything :
from them except refereing me to gamecountry. : from th
Finding Data Signal as Gamecountry. Finding Data Signal as
Gamecountry. able to find the manual for my rts-25, which was enough
for my needs.
: Third, I am a member of repeater builder and that would be why : I
submitted the post for anyone who had access to the info and : / or
programming. So thanks for the advice but I have gone all : the routes
you have said and here I am, still have no programming : capabilities
available, and even if I paid the $20 for the : manual, its pointless
without a n prom for the unit.
Well... I and some of the other group members look at prom based cw
ider's as something worth spending time on/with only if you have the
burn and the extra available time to make it work for your needs.
Compared to circuits like the "ID O'Matic"... (programmable cw id
unit/kit)
Now a'days it's not cost effective or practical to deal with prom
ider's but they can still be made to work. I still deal with them in
self contained Spectrum Repeater (and Spectrum will sill provide them
for $50 each chip) Controllers for my own retrofit work...
So make the call for yourself... do you want to learn something,
spend the time and probably a bit more money versus going the ID
O'Matic route? A bipolar prom based cw id unit can still be used if
you really want to go there.

There are two or three practical ways to source out Data Signal -
Albany GA manuals and information.
First, I would instruct people to search the Repeater-Builder web
site. Scans of some of the more common Data Signal Products have
been made and dontated / sent in by various folks.
The second option... post a want here on the Yahoo Repeater Builder
Group. Sometimes people have archived manuals and would be able to
provide the requested information by typical pdf, jpg/gif scan or
photocopy.
Third... Data Signal is still in business but not doing much in the
way of their former Land Mobile Radio Product line. In fact it's
quite amazing how they were smart enough to morph into another
complete product line aka business model. You can find them at
www.gamecountry. www
I called them to inquire about a Rural Telephone RTS 25 unit I bought
off Ebay a month back. Much to my surprise they were able to find
and SELL me (not give away free) a photo copy of the original
manual, of which I was more than happy to pay for.
So... try options one and two if you're looking for a possible free
manual. The contact Game Country "third option" does work but do keep
in mind they are a business and a copy of a Data Signal Manual will
probably cost you at least $20.

Data Signal, Inc never mind finding any manual for the CWID-70.
Anyone have any info on this unit. Need to find out the pinout for
the 25 connectors on the back and about programming. Thanks David
