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: Should the search box be selected

Ah, thanks for that, Martin! I wasn't able to observe that behaviour on my iPhone, possibly because it's a 6s Plus, which has a larger screen.... In case it matters, mine is actually a 6s which is slightly larger than a 6 but I think still smaller than your Plus. Anyway, not that I know anything ab...

In portrait, you can see the search button by dragging the screen down but you can’t actually use it because it just springs back up out of sight when you release the...

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.
