I just found my Sinclair QL lurking at the back of the garage. It's going to take a bit of work to get it going again.
I built it into a metal toolbox to sit beside my desk and used a separate keyboard, which was borrowed from a VT100 and rewired to work with the QL.
My QL had not the usual 128 K of RAM, nor was it expanded to only 640 K, but I had 656 K, with an extra 16 K battery backed on a board which I could also use as an EPROM emulator when doing things with other micros. That board also contains a Dallas clock chip, so I didn't have to set the time everytime that I booted the machine up.
The extra 16 K of RAM was actually in the slot usually reserved for a ROM cartridge so it usually contained the dongle from Metacomco's port of the Lattice C compiler alongside a bit of extra code of my own.

Many people have known for decades the rumour that Sinclair Research did work on a portable ZX Spectrum prototype codenamed Pandora.
What I didn't know (and TiL;) is that they did so using a cobbled-up Timex Sinclair 2068 for it.

Still sorting through my stuff and rediscovered this: a 32k daughter board for a Sinclair ZX Spectrum 16k (Issue 1). I doubt the chips still work! 😅
