Quote from: Bryce on 09:57, 15 November 17Check the leaf switch that the play button actuates.Bryce.
Quote from: Bryce on 09:35, 16 November 17Yes, but you can easily test that with a multimeter.Bryce.
Quote from: Bryce on 14:57, 16 November 17Can't remember, can you post a (reasonably sized ) picture of the top and bottom sides and I'll tell you.Bryce.
Quote from: Bryce on 17:21, 16 November 17Of course. when it clicks there will be approx. 5V across the coil pins, so it should be easy to tell which pins are the coil and which are the contacts.Bryce.
Quote from: CraigsBar on 15:43, 16 November 17Yep. I'll dismantle it again tonightSent from my ONEPLUS 3t using Tapatalk
Quote from: Bryce on 16:54, 24 November 17Red is Coil Positive (5V), Black is Coil Negative (0V) and the two yellow ones are the switch contacts. Because the contacts will have some potential across them when the circuit is powered, to measure if they are working, don't use a continuity tester as it will probably always buzz due to the circuit current. Measure the voltage across the contacts and it should go to zero when the contacts close.Bryce.

Quote from: Bryce on 09:53, 13 December 17So you were looking at the wrong leaf switch the whole time Bryce.
Quote from: Bryce on 13:53, 13 December 17I didn't mention that there were two, but I definitely mentioned "the play button" Let me check....http://www.cpcwiki.eu/forum/amstrad-cpc-hardware/just-collected-this/msg151846/#msg151846Yup, as I thought Bryce.
Quote from: bjt on 11:52, 26 December 17I have a cost down 464 with X-Mem installed internally, works fine. Just solder ribbon cable to the Centronics holes. The external edge connector will still work.
Quote from: CraigsBar on 13:18, 26 December 17I have 2 symbiface 2 boards here, I was thinking about installing one of those internally, using the 12v from the ctm644 to power it. Is it easier to clear out the centonics holes and solder the wire through them, or just tack on to of the filled holes I wonder. I guess clearing out and poking the tinned wires through makes a better, more robust contact. Sent from my ONEPLUS 3t using Tapatalk
