Finally got round to this, captured as a WAV.
Need to remember how I ran the UK101 emulator.
flaxcottage and tinplatepete responded to me yonks ago(2021).
the WAV file is here:

Re: UK101 - "DOS" cassette
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:
