Re: Posting a 5.25” disc drive

Having bought drives from <popular auction site> in the past, only to have them damaged even when wrapped in bubble-wrap, I think if you really want to protect the drive, it can help to use a surrounding layer of those expanded polystyrene blobs (I've just realised I don't know the official term for...

Re: Electron Exile 'Helper'

I think you’ll have difficulty doing this on the Beeb version. For one thing it uses pretty much every last byte of memory, and more importantly it does hardware scrolling both horizontally and vertically, so whenever the screen scrolled you’d have to redraw the entirety of the helper area, which wo...

Re: Noob question about sound on Beeb

Quick reply: I believe you have to keep the sound chip write active for at least 8us, which is longer than you've got it active in that code. EDIT: Was going to add an additional sentence to say "I know you're tried a delay, but have you made sure it's 8us" ... but you replied in the meantime, and a...

Re: Master PSU recap

That grommet is a total pain. There are apparently tools that you can use to get it out and in again, but I generally go at it with a pair of pliers and work two small screwdriver blades into the gap between the wider ‘lip’ and the metal case, then lever it out. I’ve often found that it’s the imposs...

When your sprite plotting / reading code is running, do you have interrupts enabled or disabled?

Re: RetroClinic DataCentre remake

The DataCentre does have several advantages over Goteks. Off the top of my head: Fast import and export from/to SSD files on a USB stick, a non-volatile RAM drive, and you can even connect a hard drive to it. If you have Beeblink (or various other similar systems) and some Goteks, you can do pretty ...

Re: Using a Mac or PC for BBC games authoring

The -boot option unfortunately defaults to performing a *RUN, which is no use for a Basic file. I did create a blank template SSD, containing a manually made !Boot file with the CHAIN"DROID1" in it. However, running the above command overwrites everything, which is a shame. I think you can work aro...

Well done with building BeebAsm locally and creating SSDs! BeebVSC is great (I have it installed) but yes, it's more for assembler than BASIC. In the end, I didn't use BeebVSC's 'build' and 'run' features. Instead I just used Visual Studio Code's 'tasks' feature. I created some simple script files t...

Re: Using a Mac or PC for BBC games authoring

By the way, if what you want to do is create a BASIC program in a text editor and then run it under emulation, one way might be to use BeebAsm to create SSD files which contain the tokenised BASIC program and are already set up to auto-boot and run that program. You could then edit your BASIC files ...

Re: Discbeast, new disc and archival utility -- NEED VOLUNTEERS

If you don’t issue FDRV then it copies them all to one drive, and on DataCentre the RAM drives 0 to 3 are all too small to contain 80 TRK files. If you issue FDRV n then it’ll copy to drive N and N+2 so in your case FDRV 0 should fix your disc full error by saving to drives 0 and 2.

Re: Discbeast, new disc and archival utility -- NEED VOLUNTEERS

Right, so here's how I do it on a DataCentre: After turning machine on (assuming RAMFS is default filing system), import Discbeast files onto RAM drive 0, by doing: *DR. 0 *IMPORT DB041.SSD Then for each disc: *DR. 0 <shift-break> ... to run Discbeast FSYS RAM // This tells Discbeast to issue '*RAM'...
