Just taken delivery of my ebay find 6022, which still works perfectly after twenty-odd years. Why can't they make them like this any more?

One query, on the back of the unit below the heatsink there is a five pin socket. Does anyone know what this is for? I worked out what to connect to the yellow/red/brown terminals and know that the sockets on the sides are for 6035/6 and keyboard/memory units.

Thanks Mark - guessed it might be that but was just checking.

No - not a problem as I found the decoder addresses for the buttons on one site and have now figured out what all the sockets are for. It's a really simple bit of kit - the brown/yellow terminals go to the 16v AC output of a transformer and the red/brown terminals go to the track.

It was happily shuffling a couple of locos up and down on a quickly assembled test track within 5mins of opening the box, so I think all is well. Now waiting for a 74444 digital point control kit so I can test that side of it. I plan to upgrade four strategic points, probably those which will be hardest to reach.

Edit, data for anyone else who has one with no instructions:

The loco control buttons - 1 is address 10, 2 is 20, 3 is 30, 4 is 40

Edit, after further playing:

The point control buttons are 253, 254, 255 and 256, after a bit of testing button 4 turned out to be address 256 so I assume 1 is 253 and so on.

Yes it does work perfectly with the "built in" decoders for C track points, I've fitted one to my track pack double slip (which lacked a motor as it was from a pack, so used the combined motor and decoder kit) and it behaved perfectly on test. Now to convert another three strategic points.

If I see a 6023 at a price I can afford (and a seller that will take Paypal) I may well buy one - can they do the same things as 6051 in terms of receiving feedback signals from contact tracks via a module? The idea of replacing my 6600 with a computer controlled shuttle line is very appealing!

Hi Matt,

Not only will the 6023 do the same thing as a 6051, it will do it much faster, although I'm not sure you get access to F1-F4.

Cheers.....

Mike.

To be precise, f1-f4 is available, but can't be sent in the new format. f1-f4 differ very much in old and new format, so as most deocders understand the new format, barely none exist that can use the 6020/22/23. However, there are a few out there: Tanzwagen, Gesellschaftwagen, measure car, old stationary crane... And home built decoders based on the original Motorola IC.
