Welcome to another Trash to Treasure series. This time we explore a donated Acorn Electron. As T2T series go this one isn't in bad shape at all. It obviously needs a good clean and we'll be taking precautions before firing her up.
Lets start by getting familiar with the system in part one.

So glad there are guys like you out there keeping these old gems alive.

In some ways, the Elk was leading the way, the Plus 3 expansion for example, providing Acorns ADFS (advanced Disk filing system), as opposed to the BBCs somewhat limited DFS. It also provided a 3.5" diskette drive, rather than the more common and less robust 5.25" drives as used with the Beeb.

This was my first computer while I was still at school. I spent a whole 6 weeks holiday playing elite and trying to write a version of the blockbusters tv show.

I did my BSc final dissertation programming on an Elk. It was handy that it was a little slower than the BEEB, since it meant if my work was acceptable on my home unit, it would look really good on the Uni's BBC suite boxes. BBC BASIC was really jolly good for matrix and vectoring calculations and the 32K limits could be worked around with some flashy memory page work and use of the chain command (basically, with a disk drive you could CHAIN in procedures into an area between user and graphics mappings as they were needed. the ADFS was surprisingly fast at reading.

True story, I've actually seen one of these control an indie brewery in 1992 as part of a High School Insight to Industry project! Seriously, their entire brewing process was controlled by an Acorn Electron! Though to be honest, they were mates of my physics teacher, so the fact they'd go for the cheaper BBC Micro shouldn't surprise me. But I was still blown away by the sight of an Elk running a brewery! Problem about the Acorn Electron having a real keyboard... so did the Commodore 64, though it didn't have BBC BASIC, it had a really limited, ancient version of Microsoft BASIC that was originally intended for the PET and had never been upgraded. I wonder what all the unpopulated pads on the Electron motherboard were for... MODE 7? (Teletext mode, nothing to do with the SNES) Isn't Steven Furber now at Nottingham Uni and appearing on the likes of Computerphile? Perhaps MS-DOS could have run on the BBC with an 80186 connected through the Tube Connector. There's something about this little Electron tha makes me want to see her working again!

In the earlier revision (the one without the socketed ULA) there's an empty place for riser pins. Probably for some diagnostic, but it's not mentioned in the service manual.

The Electron was the ''feck you Sinclair'' computer, design by his former employee who left/was fired for having different ideas about what the ZX Spectrum and its successors were supposed to be like.

Can't wait for the next part! Please keep doing those camera close ups; I haven't seen an Electron in person and that's as close as I can get to this beauty! For some reason, these weren't as highly successful as the Speccy/C64/Amstrad 464 trio, at least in my country (Greece).

Countries all had their own quirks. I was in the netherlands in the Early 90's and ended up with secondhand 8 bit micros... In my case the only ones I've ever owned were both Atari 800XL (I had two because they were being sold as lots with a huge amount of games. So for the sake of that I ended up with a green monochrome monitor, a plotter, two tape drives, and two of the systems.) Aside from recently at a game show with a retro area, the only systems I've seen in person and seen in action, because a friend of mine had them, were a c64, Amiga 500, and an Amiga 2000 I also know my uncle, who was some kind of musician had an Atari ST, which I've seen lying around, but never seen in action... It's one of those things I guess. I had a lot of exposure to computers because of my mother's jobs... But the vast majority of those were PC's... Most of the 8 bit systems were also somewhat before my time, really...

The problem is as a home market BBC the electron became not very relevent nowadays as due to it not being professional used still school grade anymore BBC Micros are going to the homes now in retro gaming era.

@mapesdhs597 6 жыл бұрын

Thanks for this! Are you going to Retrobright the plastics? I bought some BBlonde and another brand to clean up my Electron cases, but I'm leaving the procedure until next year, sun too low in the sky now for decent exposure during the day, blocked by houses, trees, etc. Btw, do you happen to know what the most likely fault source is for an Electron with a bad display, but the ULA is ok? (checked by swapping the ULA with another system) I was thinking one of the RAM chips maybe. I agree with you about the RAM access modification, that would definitely have been the right thing to do before launch. Do you have any references to example speed tests showing the difference the mod makes? Lastly, which addons have you acquired? The Plus 1 is easy to find, but I managed to obtain a Plus 3, Plus 5, and the Music 500 system, etc. Do mention the Data Centre aswell, I have one which can be used with both the Beeb and the Electron. Ian.

@RMCRetro 6 жыл бұрын

RAM sounds like the next place to check certainly. I have been offered a Plus 1 and a modern SD Card reader solution which I hope will turn up for pt.2. I haven't seen any definitive speed tests only that it can access at 2mhz instead of 1mhz. Some sources suggest the same CPU operates up to 6 times faster in the BBC B with the better RAM access. Thanks for the tips on the additional addons I'll certainly be looking into them. Retrobriting I'm not sure on yet, it obviously needs a clean and then I'll asses its colour compared to the original shade and see if it needs it. I do have a UV light if so.

@mapesdhs597 6 жыл бұрын

If it's a RAM chip maybe it would be better to replace the ICs with sockets as the testing proceeds, make future testing/replacement easier. Hmm. Good to hear about the Plus 1 and SD reader! Will you be covering how the speed mod is done later? Might try it myself. I was attempting to write 3D programs back in the 80s, really pushed what the machine was capable of (hidden surface removal), the math kills it for sure. I used machine code in various ways, but a generally faster machine would be sweet. I remember asking my math teacher questions about the line equations of intersecting planes, questions he couldn't answer. :D Hmm, a UV light... a possibility! Think I'd rather use ye olde sun though. :D I can wait, the system has been patient so far. I have numerous units, but the main one I want to clean, the faulty unit, is my own original Electron. The other is just another unit I'm going to clean to compare the alternative hair bleaching product, see if the 3X higher cost of BBlonde is worth the expense. This is Bblonde btw: www.echemist.co.uk/media/product/jerome-russell-bblonde-maximum-lift-blonding-kit-hr.jpg Kinda funny btw, I bought my box in Tesco, ended up conversing with a woman about the difficulty of choosing which one to buy. She was waxing lyrical about hair issues of course; I didn't have the heart to tell her I wanted to clean up 35 year old plastics. :D Ian. PS.

Helloo, Love the channel! Been subscribed for a bit. or is that a byte :) Was hoping someone can help me find "Dry Film Adhesive" used to "glue" the pad on a PCB back down. I know that an epoxy is available that can resist the temps of soldering but it seems expensive and a bit messy. Was replacing the caps on an Amiga and one of the pads lifted ! Doh. Any help greatly appreciated. P.S. I also need an Acorn Electron Transformer brick if anyone can help out ! I notice someone has two ! :)

@RMCRetro 6 жыл бұрын

allan fulton Generally Electron games are re-written BBC titles. It was common for a game released for both machines would have the BBC version on one side of the cassette, and the Electron on the other. Trying to run the Elk version on the BBC would normally work, but would often be faster, usually too fast to play.
