I'm right there with you on the master being my favourite BBC model. The internal Tube port I think being one of my favourite bits, as I was lucky enough to get hold of a internal 6502 co-pro a long time ago. I'm currently watching my way through all videos, really enjoying them.
Excellent video Sir. I also own both a B+ and a Master. My Master is fully kitted out, now I can do the same to my B+.
Excellent. Keep up the good work
Very informative and a lot of detail. Thanks.
Great video, very clearly presented run through of all the features, thank you!
Pretty much very cool. Despite the hot studio. Love seeing all the details. Still thinking of finding an alternative to the 16K sideways ram I have in my Beeb. It was one of those very, very cheap boards that I picked up for next to nothing in the early 90's.
Hmmm. Previous comment with link was deleted.
Thank you for the review. Please note there is a new version 1.24 of the IBOS ROM that addresses a few legacy issues. This can be downloaded from the Stardot forums. Unfortunately youtube won't let me post the link, so you'll need to search the forum.
Thanks - I saw the message on Stardot.
That update is timely as I hadn’t got round to putting the screws back in the case yet! I’ve updated it to 1.24 and put my ANFS back to the stock 4.18 and all looks good!
And the latest 1.26 release is even better, with enhancements to the TIME handling, and allowing two values for LANG: one with Tube and one without!
Fascinating - thanks for taking the time to create this video, in such high quality - much appreciated. I fall into the BBC B fans category, rather than the Master, so learning about the Integra was quite an eye-opener. Is Ken still producing these boards?
Thanks! Ken does make new boards occasionally - if he has them for sale, he posts in this thread on Stardot: www.stardot.org.uk/forums/viewtopic.php?t=17455&start=60
@@lsbyte Yes, I got one from Ken recently. Very high quality and it worked first time.
I remember making an "ugly bug" RAM module, 2x 8k chips stacked and one 74-something on top to steer them
You mentioned the remake was from 2019? Is it still available now?
Yes, I still have a couple available. Have a look at the For Sale section in the Stardot forums. Unfortunately youtube won't let me post a direct link, so you'll need to search the forum.
The BBC micro is a fascinating computer because of all the features. This was clearly not meant to be a consumer PC with limited expansion and a minimalist OS like a Commodore or Atari.
I think it was one of the few machines which actually came through on everything promised: networking, Tube processors, CP/M, hard discs, Teletext, etc. Having the reliable schools market helped enormously here, I think.
The operating system actually looks like it's been defined properly, too: with very little need to hit hardware and everything working across the Tube with different coprocessor architectures.
@@lsbyte I don't really understand the "Tube" concept or how it works.
But will someone soon make a mini new mini version.
This was great. Dearly wish I could buy one or a modern one for my Beeb. Anyone doing production runs of hobbyist boards?
Ken often has some available - you can check and ask on here: stardot.org.uk/forums/viewtopic.php?t=17455
Not a fan of that on board battery. :)
It was done that way to keep it looking like the original board. If you're worried about battery leak, it can be removed, and replaced with a 2 pin header so a remote battery can be used instead.
