The keyboard looks remarkably similar to the 48k spectrum I had, and the little stripe in the corner is adorable. Thanks for sharing. When I used mine I used BASIC, and I "compiled" z80 machine code by looking up the opcodes, one by one, in the manual that came with the machine. I don't remember ever having access to an assembler, or compiler of any kind. But I eventually learned enough that I could hack games to get infinite lives. I have fond memories of the Speedlock system, along with Bleepload, and others of that time-frame.
