westies Posted October 31, 2011 Share Posted October 31, 2011 Can anybody help.I am trying to get the circuit diagram for a zero 1 master controller.Thanks Link to comment Share on other sites More sharing options...
Southernman777 Posted October 31, 2011 Share Posted October 31, 2011 Hi, have you heard of a group called MERG (Model Electronic Railway Group)? I saw them at a recent exhibition. They have member's bulletins about Zero One controllers & use as well as other very helpful information. Maybe worth looking t via the web in the first instance?Have fun, Link to comment Share on other sites More sharing options...

zzpjl8 Posted November 7, 2011 Share Posted November 7, 2011 Hello there, as an ex Zero 1 user of some 25 years, I cannot resist asking why you want a circuit diagram. I actually still have a master controller in a box and a slave down under! I think I have all the Zero 1 Service bulletins. I never saw a circuit diagram though. What are you trying to do? Please let me know, as I am intrigued! I thought Zero 1 was absolutely fantastic and was so far ahead of its time it is not funny. When the sad day arrived for me to migrate to Hornby DCC, I literally unplugged the two wires from the back of my master controller and plugged them into my Elite. Oh, and of course, had some locos ready with DCC decoders! regards Nick Link to comment Share on other sites More sharing options...

westies Posted November 13, 2011 Author Share Posted November 13, 2011 Hi Nick,Thanks for your reply.Long live Zero 1! I think it is great.I have never had any problems with this system and still use it today.Recently I was given a dead master controller and I would like to find out its problem,hence my request for a circuit diagram.I have re-vamped controllers by taking them appart and re fitting into custom made enclosures/layout boards with great success.Enthusiast friends have been impressed and made them think!It is still a good system and treated with the correct handling that DCC requires produces good results.Regards,Geoff Link to comment Share on other sites More sharing options...
Augustus Caesar Posted December 12, 2011 Share Posted December 12, 2011 Hi westiesDon't know if you ever got the diagrams you were looking for but you could try this link.The circuit board used in a Zero 1 Controller was a Texas Instruments TMS 1000 Microcomputer. It was regarded as one of the best of its kind in its day and TI made several series of this type of microprocessor. Have a look at the link as several circuit diagrams are on there in .pdf format and I didn't have time to look at them all for you unfortunately.http://www.datasheetarchive.com/TMS1000-datasheet.htmlHope this helps you... :) Link to comment Share on other sites More sharing options...

RenB Posted December 23, 2011 Share Posted December 23, 2011 Evening. Would be good if you could share the Zero 1 info docs as just re-kindling the Model Railway bug. Have lots of kit from the 80's including a full Zero 1 system which bought second hand before the layout was taken apart, never used it much at all. About to set up a new layout and plan to use the Zero 1 rather than spend on new DCC for the time being.Darren Link to comment Share on other sites More sharing options...

westies Posted January 3, 2012 Author Share Posted January 3, 2012 Hi,Good to hear you are interested in Zero 1 for your project.I am using it with success but I must say that low speed control is not quite as good as the newer DCC systems. From what I can gather,and I am no electronics expert,this is to do with the speed steps.I joined MERG where there are forums,technical bullitins and circuit diagrams,all good useful stuff.I must say that track and train pick-ups must be clean-this also goes for the newer DCC.Good luck,Geoff Link to comment Share on other sites More sharing options...
RenB Posted January 6, 2012 Share Posted January 6, 2012 Hi GeoffFinding even with the old 1980's 3 pole ringfield's they work pretty well at slow speed, yes they are maybe not as smooth as later models and DCC, but the Zero 1 system does have a fair number of steps. I have the Binary data code and will dig it out to see how many exactly. I feel its the same control as on DC at slow speeds on these older locos. Don't have anything new with later motors to try it on mind! Think the system works very well with good operating motors and as you say a fairly clean track is required, likewise for DC and DCC.Have only got it running at present on a oval of track whilst I make the baseboard up in the loft but the features it does offer work well. I am interested in trying to find a MicroMimic Panel and LED driver unit, I have the main Micromimic unit and loads of LED'S but need the missing link! Still searching though. If I had a circuit I would make them. Is the circuit for the Display Module on the MREG?May have to join it but its not exactly cheap for the small info I am afterIf you need to re-furbish your Master Control keyboard don't buy a kit, its easy to do and if you have some Zero 1 coding paint you can re-furbish the rubber key pad also. Mine was pretty useless but now works with a feather touch! I may start a Zero 1 website to post all info I can find on it to share for free. Such Re-furb actions etc and other advise such as adding suppression to the track to help prevent any shorts damaging loco Chips etc.Always good to hear other are using Zero 1, the demand for the kit on Ebay is unbelievable, loco modules going for £10 each on average. At that price DCC starts to look attractive even.All the bestDarrenwesties said:Hi,Good to hear you are interested in Zero 1 for your project.I am using it with success but I must say that low speed control is not quite as good as the newer DCC systems.

Phil_Spiegel. Posted January 31, 2012 Share Posted January 31, 2012 And ask on the MERG Yahoo Group and you'll probably get more support. Link to comment Share on other sites More sharing options...

charles_harris Posted December 31, 2020 Share Posted December 31, 2020 Hi Folks Just following up on this thread. Is westies still about . Would like to know latest developments he has on Zero1 and what he did to repair his master losing power. Any new developemnts on the Zero1 front I would like to hear about. Thanks Charles Harris Link to comment Share on other sites More sharing options...
Fishmanoz Posted December 31, 2020 Share Posted December 31, 2020 Charles, if you'd taken Chris's advice in the post above yours, you'd have seen westies has posted only 16 times, the last one 10 years ago now, so little chance he/she is around. But why not use the MERG advice given? Link to comment Share on other sites More sharing options...

96RAF Posted January 1, 2021 Share Posted January 1, 2021 There is a current forum member username zero1man who runs a Zero 1 group that collates all known information about these devices. Hopefully he will spot your post and respond. Link to comment Share on other sites More sharing options...
