Doing things with an Amstrad PCW

It's the last day of RC2017/10, and since I had initially said I wanted to get my PCW working without its screen or disk drives, I thought I should try doing that. I had a spare motherboard, so I plugged it in to my circuits, connected it to a power supply, and it actually worked. Well, it nearly worked - my spare motherboard only has 256Kb of RAM, but my SD card driver currently uses page 16, so it hangs once the FID driver loads. Also, my power supply connection was dodgy, so I had to hold it to make it work, which meant I didn't have a spare hand to photograph it working. But I've now proved it works, so I just need a case and decent power supply to put it in. And I need to get everything put on a PCB.

I've also tidied up the boot code so the screen doesn't have rubbish on it, but has lines appearing as J15CPM3.EMT loads, like a standard boot, except they're vertical, and much faster.
