Cover was removed as the Trump card was going to be the I/O and memory for a z180 project. Sadly I can't find the cover plate, but the unit was working with my QL prior to being stored.
The ROM version is 1.37
Selling for £40 plus postage as missing the cover - you will need to do something with this before powering up, as the regulator uses the cover plate as a heatsink, but it should fire straight up.

I'll take it. Can you PM me a shipping quote to Texas, 78664? Slow method is fine. Or send me a paypal invoice to my personal email?

I believe Dave is taking this, so yes it's no longer available, sorry.

Hi,
On the list of things to do, is produce a CAD drawing of a Trump Card Cover, from the original cover I have.
I would then produce a 3D Printed version and replace the 7805 power regulator with a DC-DC converter, giving no heat.

I made a mold to make covers out of carbon fiber, which has better EMI properties. I make buck regulators. ![Very Happy :D](./images/smilies/icon_e_biggrin.gif)
