Hitachi MOSFET application note 1989

And the early nineties in Queensland.

I don't have ABSE available from my ISP, any chance of a website to download it from?.

Me too if possible please.

Yes, many outer metro or regional exchanges were 6 digit working much later than the mid to late 70's.

I was referring to capital city/metropolitan phone numbers. Plessey Components (the supplier of the app note) were in Villawood, and this being a large light industrial area, would have been a prime candidate for growth in telephone numbers in the late 70's. I don't know when the exchange serving Villawood was converted from 6 digit to 7 digit working but I think it would have been before

1980. In WA we were modifying exchanges ready for 7 digit working in 1972 and this changeover commenced nationally around the middle of that decade if my memory isn't too vague. If anybody has more definite info I would like to hear it.

I don't have a website and I haven't any plans to set one up.

With any luck, Franc will do this and let everyone know where to find it (perhaps?).

This one seem to be the exception - maybe it was too big.

I might be able to help in a few weeks. Alternately I can email to anyone who wants.

I do live in the metropolitan area of Sydney (where we still held

6-digit numbers until the 80s) :-)

Well, that just proves that there is always an exception to the rule. It depends upon whether the particular exchange area you live in was stagnant in growth or not - the area code was probably padded with an extra digit to make up the 7 digits. The fact is that Telecom (or PMG as it was then) was preparing the network - Australia wide - for 7 digit numbering back in the early 70's and the switch to 7 digits occurred in the mid to late 70's in MOST city/metro areas.

Here's an extract from a 1978 newsletter by the Action for Public Transport (NSW) group. The entry of events for May the 14 contains both 6 and 7 digit number examples.

If someone wants to email it to me I can put it up on my site. Doesn't show up on my ABSE server.
