Nice drives. =D> Now a 5.25", 3.5" AND a Gotek in the same case would be amazing! Is it possible, I wonder? Physically fitting all 3 into a full height case would be possible, using something like this for the Gotek and 3.5" floppy: https://www.thingiverse.com/thing:4237727 But you l...

Not so much received, but finished building. All working really nicely. The switch at the LHS of the 3.5" floppy drive is used to toggle which drive is drive 0/2, and which is drive 1/3 (or drive 0/4 & drive 1/5 for ADFS). I'm going to add the same switch to the Gotek / 5.25" floppy dr...

That HxCFloppyEmulator version looks a bit old. I have v2.5.6.7 and I took the first HFE (Elite) and it loads fine.

Ah. Just downloaded v2.5.6.6 (couldn't find v2.5.6.7 at first glance) and that seems to have fixed it.

Edit: Found v2.5.6.7 as a Beta download.

Thanks

Do you know why the HFE files in your archive (at least the ones I've tried) won't load into HxCFloppyEmulator? Can you give a link to a specific HFE or two? And I'll check them out. Cheers Chris None of the ones I downloaded worked with HxCFloppyEmulator. So that was: Elite Hopper Colossal Adventu...

I alway use IPA! Not had any residue issues or any other problem! I either cut the top off the disc sleeve, if the disc isn't going to be used any further, or cut the plastic 'welds'. Remove the actual disc laying on a sheet of paper towel. Then use a 'makeup remover wipe' soaked in IPA and wipe fr...

You've been unlucky! The early Level 9 protection is _not_ 1770 compatible and is expected to fail with exactly that error code $0E. I think the catalog or !BOOT sectors declare themselves as 512 bytes or something like that. The 8271 can read them as 256 bytes by force anyway, but the 1770 is only...

I've just downloaded a couple of .hfe files from the archive (Level 9 Colossal Adventure & Snowball Adventure), and copied these over to my gotek (Flashfloppy v3.23) but I get a disk fault 0E with both of them when trying to read the disk (1770 controller / DFS2.26). If I try loading the .hfe im...

After removing the disk from its sleeve I tried the isopropyl alcohol on an unused part of the disk, but it left a horrible residue, so in the end I just used a cotton bud and some water. The marks are still on the disk, but it otherwise seems to be working ok: https://stardot.org.uk/forums/viewtopi...

For anyone who's interested, here's a hfe version of Mini Office II taken from my original disk. Everything seems to work, apart from the Word Processor . Unfortunately, my disk was a bit mouldy, so I tried to clean it, and I'm not sure if that made it worse. Edit: Ran it through Greaseweazle a seco...

You can clean it with a cotton bud and distilled water. I have a load to clean I keep putting off

Does it need to be distilled water? What would isopropyl alcohol do to the disk?

Thanks Fredrik, and congratulations! I'll probably start taking a look at porting this after Christmas. I'll probably promote the current Acorn port to beta status at that point, and then the port of Ozmoo 5 will be marked as alpha. I see a sneaky version update has recently appeared on your github...

Yes, that does look very much like it. As you suggest, possibly single sided vs double sided.

I wonder if they would be of any interest to the computer museums?

Whilst looking for some 3.5" floppy disks, I came across a handful of these. They appear to be 2.5" diameter. Anyone seen these before???

Looks like you've not been active for a number of years, so not sure this will go anywhere. However, I may be able to help out with some of your missing collection. Having a dig through some of my old collections, I've found: Creative Graphics Missing Signs Word Sequencing PM me if you're still inte...

HI, I'm interested in a 1MHz level shifter and remote mounting. Can you PM me please ?

I can do that. I've sent you a PM.

Sorry I wasn't clear: what resolved the issue was rewriting all the code which actually accesses the via in machine code. The code which converts between the chip's BCD registers and the Beeb's date strings is still in BASIC. I think the problem you mentioned about the 6502 dummy read was the actua...

I have taken a look underneath the board for any dry joints but it too looks fine. So I have ordered another SN74LS86N chip and I guess I'll have to brush up on some soldering skills. Before snipping out the old IC it might be worth reflowing the solder connections on the existing IC, just in case ...

I'm interested in a 1MHz bus adaptor and the extra parts for remote mounting, for shipment to the US. Looks like I'm also too new to send a you a PM, however. Mind sending me a message?

Just sent you a PM...

I've taken a punt with some of these: https://www.ebay.co.uk/itm/324299652490 They're high density - not suitable for Beeb use? I've used lots of 96TPI disks in the past (mainly 3M branded) without any problem, but you may be right. Is 96TPI the same as HD, and 48TPI the same as DD, or are they dif...

I must just be lucky then, I bought just 20 Kodak DSDD's and have a 70% failure rate. 14 out of 20 failed on me. :-( Same here. You must have bought from the same ebay seller as me! The ones I've got are 48TPI and I'm trying to use them on an 80 track drive, so I wonder if that's the problem? The p...

Old thread, but hopefully able to answer this question. I've just been testing out a couple of MF503As, and they both have removable 300 ohm, 9 pin SIL terminating resistors installed.

Just sent you a PM.

Another guess... does the drive have termination?

I'm impresssed. And jealous. And now I want to do the same with something similar from my junk pile of SCSI stuff. I can't imagine they'd be that common, but does anyone have a stash of SCSI cards available for sale or can they be built relatively easily? Doesn't look like much is on the card itsel...

So, after much stalling, everything should now be available on GitHub: https://github.com/kgl2001/BeebSCSIHostAdaptor I just uploaded everything via the web interface, so I'm not entirely sure I've done it right. Let me know if anything doesn't look right, and I'll try and fix it. I'll also provide ...

Tube level shifters also on order now, so I'll hopefully see those before the end of the month. That's the Tube level shifters arrived too, so I now have plenty stock of both 1MHz and Tube level shifters. I don't particularly advertise it, but I do also have a stock of User port extenders. If you a...

An all day ticket for me, please.

A couple of nice custom made cases for my Gotek Drives (the wires hanging out the back are for the OSD)...

Those really look the part. The best looking Gotek I've ever seen. Metal?

Yup. Painted aluminium. Made by a guy on Keir Frasers Flashfloppy facebook group for a *very* reasonable price.

However, because on my Master I have filled all cartridge sockets and the internal ROM socket with essential software, I find that for using some of the larger than 16K ROMs (Spellmaster, Inter-Base, TED, etc.) I switch to my BBC with Econet. This has an ATPL ROM board, which means that all my 'spe...

Indeed, the right answer is to get all 3! I also have all 3, and as much as I try, I just can't bond with my Masters. I'm not sure why, but I always drift back to using the Model Bs. I think it's because they're easier to work on, with most chips being socketed, which then allows more internal upgra...
