Just one thing more: Did I get the pole numbering system right? Best regards, Pete W. If you can keep your head when all about you are losing theirs - you haven't seen the latest Change Note!

Just managed to get in to TT, been inaccessible all day!! Thank you all for your inputs, I'll explore the links tomorrow. Best regards, Pete W. If you can keep your head when all about you are losing theirs - you haven't seen the latest Change Note!

Hi, Please can any (UK) Tek-Tipper tell me the correct connections between the BT431A plug (goes in the wall phone socket) and the RJ10 connector that plugs into the line jack on the modem? Gracie was working on a client's computer recently. The client's modem cable had been cut and joined...

Thank you all for your inputs. In the course of my searching, I found this site http://www.landlinephones.co.uk/viewproduct.php?pinf=957-31--_431A_standard_BT_plug_(pack_of_5_plugs) which answered my queries about the various RJxx plugs and the UK (British Telecomm) pattern plugs. (Each type...

OK, I've discovered one of my errors! The UK wall connection isn't an RJ11. It doesn't seem to be an RJ-anything! Best regards, Pete W. If you can keep your head when all about you are losing theirs - you haven't seen the latest Change Note!

First, what I know (or think I know), then the question about what I want to know: Here in the UK, the phone cord connects into the wall socket via an RJ11. The other end of that cord connects into the phone via a connector resembling an RJ45 but with only 6 contacts rather than 8. A Modem...

Don't know about this newfangled OS9 and such, I'm still trying to get up to speed on System 7.5.3! [smile] With the older OS I have sometimes had to juggle things to persuade the disk from which I was trying to recover data that it wasn't the start-up disk anymore. Just a thought ... Best...

Joe, An afterthought: I don't think you need bother to use the switch - it's a momentary contact type and works through the Mac II internal logic. All I wrote in my previous post assumes you've applied primary mains power to the PSU. Best regards, Pete W. If you can keep your head when...

Hi there, Joe, I've found some more description of the Mac II power control circuit: Starting with the PSU off, a voltage between +3 and +6.5 Volts applied to the /PFW line will switch the PSU on. The Mac II power control circuit then feeds back a signal derived from the +5 Volt output to the...

OK, Joe, I'm going to have a serious look through the book now. Sorry not to have done it before but things kept cropping up! Best regards, Pete W. If you can keep your head when all about you are losing theirs - you haven't seen the latest Change Note!

My post dated 12th March 2004 in 'PC Hardware - Video issues' might share common ground with your problem (except that nobody replied to it!). Best regards, Pete W. If you can keep your head when all about you are losing theirs - you haven't seen the latest Change Note!

One of the plastic panels on my PowerMac 8600 has some broken lugs. Please can anyone tell me which plastic (e.g. PVC, polystyrene, ABS etc) these panels are made of so that I can select the best type of adhesive to re-attach them? Best regards, Pete W. If you can keep your head when all...

Just re-read my last post and see that it is a bit ambiguous. I didn't mean to convey that 'all you have to do to get power is plug it in and put on a load.'. Yes, the /PFW signal is associated with switching the PSU on and off. The way the book is divided into different sections makes it a...

I didn't say that. Or, at least, I didn't mean to say that. The power switch in the keyboard of the Mac II shorts a line to ground. The bit I haven't confirmed yet is whether that line is directly connected to /PFW or if there's some other circuitry in between. Need more time!!! Best...

Hi Joe, I've had a quick look but not found anything yet. Bear with me, I'll keep looking. In the meantime, someone else may know and post. As regards the minimum load, I understand that the PSU won't run at all unless the load on the main output line (most probably the +5 V) exceeds the...

Hi, Apple Macintosh Family Hardware Reference Manual (ISBN 0-201-19255-1) published by Addison-Wesley gives the following: All power for the main logic board, internal disk drives, fan and Nubus cards in the Macintosh II computer is provided by the Macintosh II power supply. The power supply...

My computer is a 1.7 GHz Celeron running Win98 SE. My hard drive (40 GB) is partitioned into four, #C, #D, #E & #F. When I open Windows Explorer, the tree diagram (i.e. the left-hand sub-window) shows the Windows folder on #C expanded. I usually want to explore one of the other partitions...
