That is RPCemu running RISC OS 3.71. Using the BASIC inline assembler and Edit! Editor. Note that everything you see there comes on ROM built into the machine. Nothing is loaded off disc. I don’t have the host machine running but basically it loads the address of the message and calls the OS to write it out with some alignment gubbins. Nothing clever. Code I used (as I’m rusty as hell) is here: https://www.heyrick.co.uk/assembler/basic.html .. the for loop is part of the assembler and species what passes to run. Lovely platform to write code on. All of the applications on it were written in ARM assembly right up to the level of the built in Draw! app which is a fully layered vector graphics editor with anti aliased rendering etc. |

About ten years ago I was walking in my neighborhood and I saw an odd thing on the ground, a full height 5.25 HD. I picked it up and it was a 1G ESDI Micropolis monster. I took the 4 magnets out of the actuator and BOY are they strong! I think it's a late '80s thing. |

I have one of these drives sitting on a shelf in my office. Looking to sell, any idea of the value? |

If you can't verify operation it is not worth much, if it does work, it depends on the specifics and whether you can find somebody who wants that specific drive. Just a wild assed guess I'd peg the value at somewhere between $20 and $200. It all depends on finding someone who wants it. |
