I though the switch was to 'write protect' the ram chips, so software protection though it was a ROM and would run correctly, where if it was still writable then the 'rom image ' would not run.
Hi Andrew. You're right! Apologies for that. Ive mixed it up with S4 I think. I'll pin your comment. I really appreciate you taking the time to comment
always interesting computer vids simon...i grew up in the u.s.and had an atari 400 and colecovision!....but i have read about the bbc and its an awesome computer as well...good job!
One of my Beebs - an Issue 3 motherboard version from 1982 - is fitted with this same expansion board. The board however is faulty, I think one of the LS245 transceiver chips is the problem, as one of the lines is "stuck", so the board needs to come out to undergo surgery. I'm not looking forward to this, as they are a real P.I.T.A. to relocate as you have discovered! The problem for me is that the connections are basically "blind" as it isn't really possible to see everything you would like to see without having to dodge back and forth with your eyes until you're confident they are aligned, and then they need a fair amount of force to locate them. I agree that turned pin sockets are probably the way to go when you replace them, so good luck! Nicely shot and edited, by the way! 😀
@@martsmiscmix Thank you. I really appreciate the feedback. I've had a couple of ideas that might help you. Check pin alignments before fitting by using loose sockets to just push fit Second idea is I might fit the board by soldering in the new sockets whilst the sockets are already installed on the expansion. Just a couple of thoughts that came to me after messing up one of my Beebs. Hindsight is a wonderful thing 😂
Thank you, I'm really glad you liked it and let me know. What did you think of the price of £35 for two? I'm crossing my fingers that the second board works when the new sockets finally arrive
@ That price sounds very good to me, i got mine cheaper, but that was an unusual price. IME, they tend to go for around £30-50, so 2 for 38 is very good
@cruxinc Many many many times! I would love one but they are just way beyond what I can afford at the moment. I have many happy memories of using one back in my youth. But they are very much in my wish list, along with a Mega ST, a Spectrum 128 toast rack, an IBM XT, Amiga 600... you get the idea 😂
Really interesting vid - looks like there's quite an art to installing the board... I'm glad it was only the sockets that were damaged and not the tracks. You've got me pondering the options for extra RAM/ROM for my beeb.. just got to work out what's best for the least risk! I'm wondering if there's a PCBWay project design to support extra ROMs... Cheers 👍🏻
Cheers James. Yes the sockets were mangled. I didn't dwell on it in the vid but the pins looked perfectly aligned. However, since making the video, I've had a couple of ideas... First idea is to install the sockets on the pins before I solder the new ones in Second idea is to install the sockets in the BBC and then fit additional sockets onto the expansion board before refitting (but I'm not sure there would be enough clearance for this) Either way., check the pins line up perfectly with sockets BEFORE fitting. I might do another vid on the second board once these turned pin sockets have arrived, but I don't want to bore everyone to death with a similar video. What did you make of the sideways RAM? I had no idea it could make such a difference 😁 I'd say go for it if you fancy one. It's a brilliant 'little' board to fit, if a bit tricky. I'd follow my own advice here with hindsight and double check pin alignment with a spare couple of sockets before installing into a Beeb
@RetroComputingReboot Good luck with the replacement sockets.. your suggested approach seems to give a bit more tolerance. Yeah - I do like the idea of that extra RAM.. certainly offers less of a constraint in programming - loading samples like that is a great way of making use of it. I've got a long term project to write a game for the BBC and the extra RAM may come in handy for that ..
Just noticed you are getting a lot of scan flicker on your BBC micro monitor filming. If you want to get rid of this I suggest when using your video camera you change its shutter setting to manual and try coming down off high shutter speeds like 100-100 to 30 and you will probably find it stops the flicker. Hope this helps.
Thank you. I really appreciate that. Sadly I don't have a video camera. I shoot all my vids off my phone (currently a Xiaomi 11T Pro). I'll be getting a proper video camera at some point once my budget allows for one though, but thanks for taking the time to try help me 😊
Interesting video. I saw the hard plastic cover you have on your beebs for sale on ebay recently, the seller was asking a mere £50 for one! I think I'll give that a miss - lol. I think I might have a problem, there was a very nice 1040 STE (upgraded to 4 meg and complete with box and polys all in excellent condition ) with lots of goodies on ebay that I just had to buy. That's 5 x ST's I now have! If you need the split tos 1.04 mages give me a email to send it to you. Did you use the same dye colour on your Amiga 500 as the beebs? Bone colour, I think?
£50 for a cover? Yeh I'd leave that. I have three of those covers. I think the most I paid was £30. They are quite rare but they do come up. Just 5 ST's? Same as me 😂 although I still dream of getting a Mega. That's what I really want. The ROM images would be handy. I need to go though mine and see whats in them .I know I have a 1040STE that needs an upgrade. It's currently connected to my Megafiles and has a buggy earlier ROM that doesn't auto load the desktop config file to bring it into medium res, so am currently using a bug fix program for that, It's an annoying fix though as it's using up a bit of memory which is then causing some of the games I have on the HDD not to work. I definitely need to get round to updating the ROM and a 4MB upgrade. Yep, the Amiga I did use Bone. It's not a perfect match if you're super picky, but I think it's close enough to make me not care. Gives a really nice finish that lasts. Just watch out for getting IPA anywhere near it as it will lift it - I know from experience 😂
I'm glad you liked it. I appreciate the comment. In answer to your question, no this board isn't compatible with the Master. By default though it does come as standard with 64kB of sideways RAM which I understand can be configured to take ROM images. There's also the cartridge ports as well that can be used and fitted with your own ROMs subject to using a suitable cartridge of course.
Love the beeb, apart from the zx81 and the Speccy this felt like a 'real' computer with a proper keyboard. I have a copy of the original Elite in its original box with disk, manual and the function key overlay. At my high school we started off with 4 Apple //es but they were replaced with 16beebs econetted together. One machine had a floppy drive this was the once I used to play games on. this was the mid 80s. This was is New Zealand of all places

Nice to see crt still in action
I have three of those Cub monitors 😊 (terrible to film though 😕 so apologies for that)
Yeah, we had the Sideways Ram back in the day. And Exile is a fantastic game.

Have you considered getting an archimedes?
@cruxinc I've ordered myself a couple of RAM chips for it, so this second one had better work! 😂
@cruxinc Many many many times! I would love one but they are just way beyond what I can afford at the moment. I have many happy memories of using one back in my youth. But they are very much in my wish list, along with a Mega ST, a Spectrum 128 toast rack, an IBM XT, Amiga 600... you get the idea 😂
I used to have the Watford Electronics sideways rom board with 16k sideways ram and battery backup, it was ace
I'm glad it brought back some happy memories 😊.
What happened to your Beeb?
@@RetroComputingReboot it died many years ago i stil have 1 disk left tapper/load runner, i run BeebEm now

Thanks for the Video, do you know if these boards are compatible with the BBC Master ?
I'm glad you liked it. I appreciate the comment.
