[GreenKeys] Introduction

Gil, me old mate.

Would you really like to know all about Creed junk? In New Zealand and, I
guess Australia to a lesser extent, all the tty gear was made by Creed and
Co. Some of the earlier examples such as the Creed 7B and Creed 54 (which
was a development of the 7B) were great old machines. They were large and
heavy but very reliable, if somewhat more complicated than the Teletype 15.
The accompanying Creed tape machines were the model 85 (chadless) and 86
(chadded) which were basically 7B's with the carriage removed and replaced
with a tape punch. The 86 used 7/8th wide tape. Tape readers were the Creed
6S series (I had 2 6S6's) The 54 had a reperf and reader built in (if you
were lucky and the gears werent stripped!!)

The real Creed abominations were the model 75's....! They were (I think)
sort of copied from the later Teletype 32's which had a moving multitiered
typehead. The problem was that the Poms (Kiwi derongatory slang for what you
call 'Limeys') (no offence intended, tongue very much in cheek!) never
really came to grips with proper production engineering. So they were an
absolute nightmare to work on and adjust. They were OK on 50 Bauds but fell
to bits pretty quick on 75 bauds which they were supposed to be designed to
do. I used to rebuild them for other local hams and that is one of the
reasons that I dont have alot of hair left....To me they were the main
reason I gave up on mechanical Teletype.

My interest was rekindled by the acquisition of a couple of Model 15's from
the NZ Civil Aviaton department of the NZ Government who were the ONLY NZ
government department to have Teletype gear. This stuff was left behind in
NZ after the War by the Americans, which is why the CAA was still using it
until 20 odd years ago. Everywhere else in the government the only machines
used were Creed, later replaced by Olivetti ( Now thats REAL junk!)

Also my good friend GeorgeW7TTY sent me a model 14TD and a 28KSR to round
out my collection. I still havea Creeed 54 but seldom run it these days....

Anyway if you are really keen on this stuff I could give you a copy of
Goacher and Denny's English 'Teletype Handbook'

Theres all sorts of good stuff in there on Creed and also Lorenz..... Let me
know if you want it, Ill post it over.
