[comp.sys.att] AT&T 6300 keyboard

tes@whutt.ATT.COM (STERKEL) (12/02/88)

I bought an Inmac keyboard to replace the tired one
on the 6300 (I am getting tired of fixing it, and
a new one is cheaper than 1.5 hours of "professional"
repair.)

Anyway, guess what I found?

The 6300 uses a *NON-standard* keyboard plug.  can
someone point me to a converter from the non-standard
AT&T plug, to the standard IBM plug.

thanks,
terry

Terry,

It is not that simple.  The 6300 keyboard has its own ROM code to
produce a different signal than the standard IBM keyboard.  You can not
just buy or build an adaptor for the plug.  You have to buy a new keyboard
designed to work with the 6300.  Keystronics (sp?) has 2 versions made for
the 6300 family.  The price is from $159 I believe.

I have used both the 6300 keyboard models 301 and 302.  They don't have a
good seal against dust.  If dust gets under the keys, then they stick and
don't response well.  You can remove key by key and clean the contacts to
get better results.  And don't forget to cover the keyboard when not in use.
This will make the keyboard last longer.  My first 6300 (1984) keyboard still
works fine and so does my 6300+ (1987) one.

Bad news Terry,

The 6300 uses a non-standard keyboard period.  The existance of the 
mouse port and the circuitry to handle it are just one difference.  The
ROM chips in the keyboard are proprietary as is the plug interface.  If
you don't want to use an AT&T keyboard on your 6300, you have one alternative
(at least that I have ever seen): Keytronic makes a version of their
replacement keyboard for the 6300.  Looks just like an IBM 101 AT kbd.  No
mouse port though.  Keytronic has a good reputation.  47st Computer used to
sell them.  Hope you can return the Inmac.  This is not an endorsement of 
Keytronic or 47th Street Computer.

Watch out -- I think they are not voltage compatible -- the AT&T uses 12 volts
intead of 5 (or the other way around).  You could smoke the motherboard.


There are AT&T replacement keyboards available from a few places.  They even
have the right plug.  I picked up two surplus 6300 keyboards (301 and 302)
on the surplus market though.

Northgate Computer Systems makes a version of its OmniKey/102 keyboard for
the AT&T PC 6300 family.  It costs $124.00.  It has received rave reviews by
at least 3 columnists in the trade rags that I read. They have a 10 day
trial period policy, but you have to pay freight both ways if you don't want
to keep it.

I have no connection with Northgate Computer Systems; I have just heard a
lot of good press about the keyboard.
