Re: Hampshire/South ABUG Giveway

Thank-you and yes, those are the ones I can use. Sincerely though, if you don’t want to post (because I do recognise that it amounts to significant hassle) then no worries at all, I will happily leave them for another taker. However, if you feel that you can take an anti-histamine and bear to confro...

Re: Hampshire/South ABUG Giveway

Hi Duncan - I'm by no means an expert here but do those iMac memory modules match up to something like "DDR3 10600S PC3-10600S 1333MHZ 204 Pin SODIMM" ? I ask because I have MSI netbooks that use the latter spec modules (2Gb max) so I 'd take yours if compatible for spares/upgrading future...

Re: Setting up dual drive from single drive and gotek (level of complexity?)

Yes the Beeb will power twin drives and yes, DFS will support two physical drives (as four logical drives). On the power supply, if you could find a drive with a built-in PSU and you can cope with the slightly larger case and one more mains plug, you will be reducing the strain on your Beeb PSU but ...

Hi Tom - I’m just a Beeb hobbyist and not from a software or IT background so things like licensing, open/closed source, git(?) etc are all just complete jabberwocky to me.

Re: Deploy-and-run from PC to Beeb?

I’m afraid I can’t help with UPURSFS because it wasn't my 'thing', (I’m only responsible for the original UPURS system), so I’ll have to leave the expert comment on that to Stephen ( sweh ). My only suggestion though if you continue to struggle would be for you to first confirm that the basic UPURS ...

Re: Is an MMC DFS/TAPE hybrid FS with PAGE at &E00 feasible? (was DFS)

Somewhere , as a proof-of-concept project, I have a patched version of Beeb OS1.2 where I modified the CFS code such that whenever a byte was required, instead of it coming from tape via the serial chip, I served it up via the UPURS (viz UPCFS>UEF) engine. It only supported CFS reading and had a co...

Re: Is an MMC DFS/TAPE hybrid FS with PAGE at &E00 feasible? (was DFS)

Copy protection may well be a factor but only if the alternative loader doesn't 100% replicate CFS. Because UPCFS was a 'bonus' feature of UPURS where the latter is not a stand-alone FS rom, I had to do extensive vector-stealing and endeavour to hide lots of code ditties in ram holes in the hope tha...

Re: Is an MMC DFS/TAPE hybrid FS with PAGE at &E00 feasible? (was DFS)

The UPURS rom contains exactly this functionality in the form of UPCFS . It loads games etc in UEF format directly from a PC via the UPURS high-speed serial link decoding the UEF chunks and extracting/loading the 'tape' data blocks on the fly. Speed-wise, its not much slower than disc loading with t...

Re: Bits and bytes

Have a look at the BIT instruction too which is specifically designed for testing individual bits as you require. It’s advantage is that it is non-destructive, only setting status flags and so is excellent for iterative bit-testing of a sequence of bytes..... EF86AF2F-8524-4618-BA4B-B7A3E8EF72AC.jpeg

Without that line, the address will move up in memory each time you type RUN in a given session - that’s why you are seeing it changing all the time.
