UK101 - "DOS" cassette

[b_b_c_m_i_c_r_o_2]

Finally got round to this, captured as a WAV.
Need to remember how I ran the UK101 emulator.

Very fidelitous recording by the way.

cool, I had a go at running it ("DOS") yesterday but I think it crashed after loading. I using the Tim Baldwin emulator from when I was doing UK101 stuff in 2014. I still have on my PC, the files from then just my memory has faded in places
I probably loaded it wrong but It may be expecting disk hardware. Our UK101 had an 8 inch disk drive, but still have these disks, I was using the real UK101 up until 1985:
