Re: [Ql-Users] One Per Desk: Computer One floppy interface. Need the ROM image.
Thanks all for the searching. Fingers crossed we can get a ROM image and I can produce a design that the community can reuse in future. My Mk.I board will be to just verify the reverse engineering and hopefully get it working. Mk.II will separate the WD1772 and floppy interface onto a separate board connected via a ribbon cable, making the host interface board not much bigger than a ROMpack. It will also, given the rarity of WD1772s, allow me to replace the daughter board with a RPi Pico based floppy simulator which will be able to use images on an SD card, making the whole thing more sustainable in future. That's the plan anyway. Steve -- --- Nostalgia isn't as good as it used to be. ___ QL-Users Mailing List

Nothing in the Quanta library :-( Dan Abbot was the person who had an OPD and Tonto collection John On Thu, 14 Dec 2023 at 12:21, Stephen Usher via Ql-Users < ql-users@lists.q-v-d.com> wrote: > OK.

Dan Abbot (or possibly Abbott, unsure of surname)?

OK. The Wayback Machine just has the first version of the web page in 2007 and the C1 interface information points to the RWAP web page, so Rich, you had that PDF in at least 2007. Looks like that's along gone then. Steve ___ QL-Users Mailing List

Apparently Quanta used to have an OPD section (http://www.quanta.org.uk/systems/opd) but that no-longer exists. Do we know who is in charge of the Quanta web site now, and if they have an archive of the old site?
