My A1200 1D4 gets stuck during boot..... Reading some address like 22000.. I am betting there is a bad rom address line or something.

Now we all have very consistent results... :)

All of my A1200s are 1D4 so the board doesn't work on any of them.

I've just opened mine up and found its a 1b. Haven't seen anyone post any results from this one neither, so may grab one to give it a test.

Make sure your 1B edge connector has a bevel/chamfer. Both mine didn't and although it is ok with old style accelerators the edge connector used on new cards will get knackered!!
Get your file out :)

Received the board, socket, XTAL and regulator thanks go0se!

I didn't actually notice that. Would take a look, but just had a fight with the metal shielding resulting in blood, so put it away for today. lol. Will check it when off work next, cheers for the heads up

Tracking is indicating the PCBs from JLCPCB will turn up today, have the rest of the components ready to go, I have a 1D.1, 1D.4 and 2B to test the card on.
I noticed an alpha firmware in @terriblefire Github binaries dated 01 April 2021, is this the jed to use or is there a later version.:?: I am guessing there is a later version from reading some of the previous posts.

Welcome
Today I got few 1200 boards but only 1D4

1D4 and kick 3.2 working without any issues on two boards

later I will check on 3.1

Same here - no luck on 1D4 MB & KS 3.1, both cards give yellow 🟡 screen... Will try with KS 3.2 and DiagROM later today
