Oh my God. He has a Tatung Einstein. I first programmed in assembler on this machine. A Spectrum with CPM.
I also had the Spectrum Emulator that allowed you to strap a tape recorder to the computer and play the speccy games.
Love this site.
Still have my ZX81 - 2 boxed Spectrums. 2x C64 (old & new) and of course my Miggies A500x2, A600, A1200.
