I was considering popping down but as I haven't booked a table and relatively new (back) to the Acorn world would it be worth the drive?

I have a Master 128, poorly A4000 and have been doing some coding on my RISC OS Pi.
Master 128 with DataCentre and RPi co-pro.
RPi B+ & 3B+ both running RISC OS.
Poorly A4000 (battery damage, partially repaired).

Come on down and say hello, we will make a space for you :wink:

Don’t forget to bring the entry fee (see first post).
Also you will need a mains extension lead.

Oh, hang on, who's hooked up a 32016 second processor to an Electron? We need to know more about that!

Please note that I’m adding the comments when I can.

Things that missed the glaze of the camera:
John’s issue 3 Beeb going slow when running some software (reason unknown).
Phill repairing Richard’s Atom.
Chris showing his Bad Apple animation with a sound track on a BBC B via a CRT display. You can however see his You Tube Video here (although it looks better on a CRT).

Yes the Beeb is an issue 3 motherboard. When it boots the tape motor light is permanently on. It was to be upgraded with two of Chris Morley's SWR boards and an EEPROM board. All appeared to be working perfectly except for Interword and the Basic Editor version 1.32.

The Interword issue was solved by moving the SWR to different sockets.

The Basic Editor problem was vexing. The program worked properly when loaded into SWR, any SWR slot. When it was loaded into EEPROM it worked very slowly and then the whole machine slowed down, this behaviour even surviving a Ctrl-Break. Changing the ROM sockets in which the board was placed made no difference. Changing the EEPROM board and SWR boards made no difference.

Moving the EEPROM board which was running slowly in my BBC to another BBC showed the Basic Editor working properly.

Conclusion - the SWR and EEPROM boards are working properly. The issue 3 motherboard is the issue. That is not too worrying as I have a working issue 4 motherboard spare. I'll just swap the motherboards and use the issue 3 for spares. I know that sounds like sacrilege but that is why I had the issue 4 board in the first place. :?

My atom lives with ramrom and mmc. Flappy birds crashes if you make it through the first obstacle. There were a couple of games that were crashing: tetris and w.a.r. but they were fixed by an mmc rom update.

Thanks for the captioning Mark! Much appreciated. I know from experience it's extra work. And of course thanks for the photos.

If you know whose Elk that was, whose ARM copro, and whose 32016 copro, I'd very much like to know! (If you can get a close snap of the 32016 top label, and even the insides, that would be most excellent.)

Cheers
Ed

We have all the components locally here to replicate the 32016 configuration:
- An Electron with Plus One
- An AP5 interface
- ADFS 1.03
- A Beeb SCSI with the Panos Image
- A original 32016 Co Pro

I had this setup running briefly last year for AP5 testing, but with a PiTubeDirect 32016 rather than the real one.

I tried the same setup on my Elk (ie, the PiTube version). I think it worked ok but I can't quite remember (it certainly worked on the Master and that is clouding my memory) - was it necessary to do anything non-obvious to make it work on the Elk?

(Good point Dave, our own mini-ABUG but without the cluster of appreciative onlookers! I was idly wondering how many 32016 second processors are out there, and who has them, and what their configurations might be.)

Yes, this was a great meeting. I loved the Vixen beer. :lol:

Thanks to Alex for organising it. =D> =D> =D>

Managed to get my Beeb working with Chris's Boobip gizmos. I shoved in a new Issue 4 motherboard (well not new but you know what I mean). The board looks for all the world like a model A that has been upgraded to model B standard.

It did not have a disc interface fitted so, after checking that the EEPROM board worked and the SWR boards, the first job was to swap the 8271 DFS interface from the faulty Issue 3 board. I forgot to open S9 :oops: :oops:

Once S9 was open everything worked properly. Even the disk drive worked faster. :D

The faulty Issue 3 I shall now use as a potential donor should I need any chips from it. I have another Issue 3 bare board which is missing several chips. Maybe I can rescue that.

I was so pleased with the 'repair' that I even added Kenneth Kendall so the Beeb can talk to me. :lol: :lol:

Sorry Ed

He did not bring his 32016 co-pro into the room today. I would have asked, but by the time I had a chance, Mark was packing up to go home :(

I forgot to take the scramble source and to be honest, until I was talking about it on Sunday, I had forgotten about it. It is a simple fix, I just keep forgetting to do it!

Im back home too. I made a start on putting in the meanwell power supply but messed up the disc drive power socket. I ordered some terminals but am without a bbc till they arrive, which is sad.
I did some work on vi65 which is taking shape. Made good progress Saturday, but less today.
It feel I made a social faux pas at dinner on Sunday by inaadvertantly being the only person at our table not called Mark!
It was great to meet everyone and see what you are all working on. Chris' Bad Apple was amazing. I really wouldn't have believed it possible! Thanks also to everyone for the advice and help - especially Phil for the phone charger!

Thanks Alex for organising the event.
