Phew! Everyone needs to bit of good luck occasionally

Hi Ken, The standard 30p SD Card reader comes with a right angle Header on the Component side which would have to be removed and replaced with a straight Header on the back. It would appeal to more users if the two connectors could be made to mate directly without needing soldering skills. Perhaps ...

The floppy port doesn't have a 5v feed so adding a Gotek shouldn't make any difference to how you power the 1MHz level shifter. Unless of course you're currently using the PSU auxiliary port to power the 1MHz level shifter, and you're now wanting to use that to power the Gotek? If this is the case, ...

I've used ribbon cables about 80cm long without any problem. Can I just check how you're trying to connect PiTubeDirect to your Master? I assume you're using a level shifter to interface between the Master tube port and the RPi Zero. Assuming you are using a level shifter, please make sure the ribbo...

Is the RJ45 pinout compatible with the "blundell" standard? Can you enlighten me? I have some structured cabling in the house that I would use, are standard ethernet patch cables not suitable? The 'blundell' standard is a definition of the pin mapping between the DIN and RJ45 connectors. These boar...

Looks good and I’m think maybe an opportunity to tidy up the wiring of my setup. I have a lot of cables going around the place... Would I be right in thinking that these avoid the need to daisy chain loads of cables together and allow up to six beebs to be plugged directly into a single hub? FC7A49...

Just had a quick read through the change log, and there's been a lot done since 4.14!

Good job .

Flashfloppy is very flexible and can be configured for different interleaving options. There are default disk layout assumptions made for the different file extensions, but if they're not correct, these assumptions can be overridden. See img.cfg options here : file-layout = interleaved* | sequential...

RAM issue with me too on my B+. I thought I had posted about it on here, but it was actually discussed on the BBC Micro mailing list:

I went to start up my L3 file server yesterday and when I ran the FS3v125 file I started to hear a very high pitched squeal coming from somewhere around the Econet hardware, and the computer locked up. I've got an IntegraB board installed in the computer which sits over the top of the Econet hardwar...

Hi Ken, Minor point. Running on a Windows 10 x64 system, some of the disk images are not showing the correct directories: That's interesting. Which language settings are you using on Windows? It looks to me like it's translating regular ASCII characters to a different code table. Hmmm. Not actually...

Minor point. Running on a Windows 10 x64 system, some of the disk images are not showing the correct directories: MMBExplorer1.PNG A couple of additional feature requests from me that would be awesome: the facility to add / remove individual files from the .ssd images via drag and drop. There is usu...

Looks good . I'll give it a test tomorrow.

My 1MHz level shifter board requires a 5V supply to power the level shifter and RPi Zero. The usual source is either from the Tube port or the User port. However, if these ports are already in use, then an alternative source needs to be found. If the tube port is in use, then I'm pretty sure in most...

Hi Ken, these boards look great. Could you put me down for 1 underside tube shifter please.

I just built a new batch recently, so no problem. I'll send you a PM, but since you've only got two posts you probably won't be able to reply, so I'll provide you with alternative contact details.

Duh! Turns out this was a Flashfloppy configuration issue. When initially fault finding I was switching between 8271 an 1770 machines. Bad idea. This was masking the fault. When I took my Gotek to another 8271 based beeb I saw the same result. Turns out I had previously altered one of my Flashfloppy...

Here's a couple of screen shots showing what happens:

Reviewing the circuit diagram, I've either swapped out or tested the following: IC77 (74LS00) - Tested in logic tester IC78 (8271) - Swapped with known good IC79 (74LS38) - Tested in logic tester IC80 (74LS38) - Tested in logic tester IC81 (74LS393) - Tested in logic tester IC82 (74LS10) - Tested in...

Hi folks, My primary beeb has started misbehaving again. It's a issue 4 board with 8271 disk interface. When I try to LOAD or *LOAD larger files (eg ROM images) I get a 'Drive fault 10 at xx/C1' error. Catalogue shows up fine, and LOADing or *LOADing small files works fine. I'm using DNFS 1.20, but ...

Yes, I've still got a few of these available. I'm a bit busy right now, but I'll try and reply to your PM later this afternoon.

It's not entirely clear from the photos, but from what I can see you're wiring looks correct, so it does sound like you're almost there. Instead of using the specially modified version of MMFS, all you need to do is download the latest version of MMFS that Dave has linked to and transfer the mmfs.ss...

Okay i've built the MMC interface, soldered it up to a 20pin Idc user port connector using the pin outs below: Can you post a photo of the card and the 20 pin IDC to check if the wiring looks ok? Okay i've managed to load the MMFS onto my BBC's sideways RAM and with my device attached + card insert...

Could a menu system be incorporated into the PiCoPro? E.g. *TUBE 0,0 - (maybe?). It seem there's getting too many to remember . . . Well, for some of us

Dave H

That would be cool. And *TUBE without any parameters could list the options.

Sorry for the delay in getting back to you on this. I've just tested the Liteon drive, but couldn't get it to read CDs. However, I do also have a spare Hitachi / LG GCC-4481B DVD / CD drive that does work. It also has the retaining clips to hold CDs in the vertical position; albeit they're smaller t...

I believe the CF cards (with suitable CF / IDE adaptor like this) are directly interchangeable with the IDE HDDs. The CF based drives would therefore require the same patched ADFS as the IDE drive.

I've got one of these. Not sure if it's working, but I should be able to test. PM me if interested...

Possibly not the reply you're looking for, but it sounds like you need to replace the 16MHz X1 crystal in your beeb:

I'd be very interested what other people use and recommend. I built a 40 pin breakout board to help with the testing of my 6502 Co-Pro. I never actually needed to use it in the end: https://stardot.org.uk/forums/viewtopic.php?f=3&t=18602&p=258556#p262496 I've got a few spare boards and the parts to...

What about a hardisk ? (I read for exemple that DOOM perhaps need a Harddisk as the files are big) If your primary goal is compatibility to play games, then either the Gotek or MMC solution is the best way forward. Most games will not run from SCSI drive unless they are specifically patched to do s...

I also want a hard disc, so I have a GoSDC. I have no intention of buying a real Winchester (assuming one still actually works)! Whilst the GoSDC and other IDE options are good, they do all require a patched ADFS ROM. If you want to be a bit more authentic, there are now a number of SCSI disk optio...
