I believe very few buying customers preferred joysticks. Always the keyboard - actually tried some analogue joysticks on it recently and it was horrible! I found the keyboard controls pretty intuitive. Even though I generally prefer keys to joysticks, I always played Elite with a Voltmace analogue ...

I should be able to join too.

Thanks,

Rob

But of course it also needs to be over the /correct/ track and a 3.5" disk is 135tpi which works at about 5 tracks per millimetre. If you've tweaked the position more than very slightly then it's possible that the head might end up correctly centred over the wrong track. The easiest way to check th...

CJE Micros have the original Archimedes drives: http://www.cjemicros.co.uk/micros/indiv ... -800KFD310

They are pretty hard to get hold of so I suspect that's why the price is so high.

Pop me on the waiting list for a VideoNuLA, please.

PM sent.

Brilliant

Mostly I want a text editor for plain text files. I know View files are more or less plain text, how about WW and Interword though?

You could try Edit.

On the B or B+, I think you'll need to setup a "multiply by 512" table and then set &E0/&E1 to point to it. I'm not sure this is possible on the Master as I think the equivalent table location may be hard-wired in ROM? Assuming you've moved the start of screen memory up by 4K, I also think you'll ne...

Rob, could you add me to the waiting list as well? I'd like to reserve two Video NULAs for my two masters. I'm pretty sure the ULAs are soldered to the motherboard in both machines so I'll be needing the sockets as well. PM sent. (I always included a turned-pin socket with each board just in case t...

As you say, the Beeb was designed to use ROM software. There's a good selection here: http://bbc.nvg.org/rom/

Excellent - well done

Hi Rob, I'd be interested in a VideoNULA - is there a separate version for BBC-B and Master, or will it fit either? Thanks - I've just made a batch so just waiting for those who'd previously expressed an interest to confirm whether they still want them or not. I'll PM you later today depending on t...

Could you me down too please (although I may have to dip in and out a bit)?

This mentions the Sony CDU571: https://armclub.org.uk/eureka/eureka42.pdf This mentions the 771: https://www.4corn.co.uk/archive/misc/Phoebe%20Assembly%20Instruction%20Sheet.pdf I have a 571 in my Phoebe case and it lines up correctly. However, as mentioned previously, fixing it in place without the...

This CDU571 should also fit (and was listed as to be used in Phoebe by some references): https://www.ebay.co.uk/itm/233505255260?var=0

Yeah I know. I take a similar approach in my 8 bit development using cc65 (C cross compiler for 6502) with inline asm for the critical bits. However C is a lot nicer than BASIC for writing anything halfway complicated (like a file server.) True - C is my preferred language but I guess it wasn't rea...

OMG who would write a file server in BASIC!?

The Beeb's BASIC is very fast and there's the in-line assembler for time critical bits

Great stuff - would be good to have a run through of this on one of the Dev nights if possible. It uses the smaller screen as an optimisation and so that X fits in 256 for MODE 4! I can't remember if there is a hack to make print work, but full screen MODE 5 would be fine. I'm sure there is at least...

Please include me in your VideoNuLA board build quantities when you next build.

Will do. I've just received (well yesterday) a new batch of PCBs so I'll be making some up soon.

Any chance you could send a PR or email the sources so I can add them to the repo properly? Can do but all I did was apply the HacMan fix to the game code on the M128 and B+ to create the modified binaries and then hack separate copies of the loader to call the appropriate version. If you can point...

Try ImgToDisk: http://mdfs.net/Apps/DiskTools/

Mine arrived last week and I finally tested it out yesterday.

It's excellent and really easy to use once setup. Love the little wireless icon too!

Back in the late 1980's I used a Jessops Turtle in my classroom. The circuit appeared to be quite simple so I wrote to Jessops and asked for information. Within a few days I had received a letter back with the attached information which I have recently scanned to pdf. Having just seen this thread t...

Here's a quick hack that contains the B, B+ and Master 128 versions and will automatically select which one to run.

I wish I were better at this as it's amazing and definitely the best 8-bit version by a mile!

EDIT: Removed my hacked version as Dave's official build above is better!

Said Reverend must be either spinning in his grave, or sitting in a darkened room clacking the rosaries, what with modern media advertising.

Quite possibly. Although I was wrong about it being a complaint as he was actually commending Acorn User for covering the young lady up:

I think the software is on Chris's Acorns: http://chrisacorns.computinghistory.org ... ml#PCCards

I'm pretty sure I have the Jessop Ralph software somewhere but it's well packed away at the moment. However, it can be driven from Acornsoft Logo (2 ROMs) with the use of the extensions disk. The roms are here: http://bbc.nvg.org/rom/Acorn/lang/ - from memory, use Logo-1 (not Logo 1-12) and Logo-2-1...

Curses...in storage! So it'll be March 2021 at the earliest before I can go and get it without risking being shot at by Col. Blimp. I've got one in front of me - I'll take some pictures today. I had it open a few weeks ago as I had to replace the toggle switch... EDIT: Pictures added. Watford UP sp...

I'd like to attend too please

I'm pretty sure you could load Superior Speech to sideways RAM so it's entirely possible that someone burnt it to an EPROM and your memory is correct.
