More of a heads up than anything, because I stole the first one, but the seller has "several".

http://www.trademe.co.nz/Browse/Listing ... =743938222

Apparently new sealed in box. I'll only be buying one so there should be more to go around if anyone is looking.
Made this post because they're impossible to find when you need one.

No doubt they'll relist soon and I'll ask how many they have as well.

Was sealed as new. I've opened mine and it honestly looks like it was made yesterday. I hope the seller relists some more - they sent me the display but never replied to my email.

But I'm mostly posting to say:

Pro - has 14 pin connector for your Amstrad PC1640!
Con - wont work without an Amstrad PC1640!

It's got a 66W PSU inside, which wont turn on unless one of the pins is grounded, this is labelled "Connect Protect" - so I suspect it might be wise to link in a dummy load for each rail as well. Thankfully the entire circuit diagram (with labels for connectors) can be found on the interwebs: https://archive.org/stream/amstrad-pc16 ... 7/mode/2up

It appears to be monochrome CGA that supports EGA resolutions
Also requires a load on the internal PSU or it does nothing.

Works though.

Haven't heard from seller or seen a repeat listing yet?

Guess what...

yey

I'll retract my earlier statement about it being CGA.
Apparently it is hercules /MDA (I found conflicting resources) and mine is just failing to sync.

Just an update on mine.

It certainly is MDA.
PSU really wants to be driving a full PC (rated 66W) - anyone who grabs one should either do this, or plan to hack/install a single +12V DC line for the monitor and disable the full PSU inside.
V-Hold - adjustment helps, but I can't lock on, and I'm getting a strong pin-cushion effect. The lack of V-Hold varies at random.

Mine will likely go back in it's box while I finish my HMM-1200 MDA repair, and then become a project for education rather than requirement.

Full circuit diagrams + test points and readings/adjustment instructions are available on the net (yey Amstrad)
If anyone else grabs some of these, let me know how you get on
