I could test the Turbo board out for you? At least then you'd know if it was the board or your Elk playing-up! I have a box full of Turbo boards . . .

Wow! . . . Another great project - but Sarah, we need to have a serious talk about this > (note - MASTER, not B+, B w/ SWRAM, or any variety of Electron! ) Dave H :lol: And I'm only teasing . . . So take no notice of my continual Electron comments whatsoever, I know the games you work-on will, prob...

Any way to get them to Cambridge?

The video link from the purchase suggested using rubbing alocohol (IPA?) but advice on here was distilled water - which is the best way forward?

Distilled water isn't going to 'kill' any mould, just wipe if off. IPA

Mine has arrived - has been built and is now waiting for connectors from RS . . . Cable will have to be in two pieces, but not an issue!

Many thanks, fizzyade, for putting the kits together . . .

I found an IDE interface in an A310 that is labelled "SF & PS IDE". The copyright mentions Peter Szymanski. It seems similar to the ICS interface, but not quite the same. Yes, Peter had a partner - I came across his name yesterday, whilst looking for something else - If I find it again I'll add it ...

An Electron for £130 . . . and almost next door one starting at £0.99

Does anyone have a working copy of the P.R.E.S. Plus 3 Welcome Disc, please? I need a copy to carry out some testing. I have two copies that are unusable

I do have two copies of the Acorn Plus 3 Welcome Disc - But these are not suitable for what I need to do.

Thanks - Dave H

Do you have one of the original Slogger boards? As I have one so could possibly do comparative tests if needed. I do, thanks for the offer, though. I did some testing yesterday and I did find a difference, with the MRB fitted, but I'm not convinced it is to do withe the MRB!! More later . . . Dave ...

ATI cases are now available for users with Low Profile IC sockets fitted. If yours has standard IC sockets fitted I can change them for you. The labels will be available later this coming week . . . Dave H

Glad it wasn't either of my boards, but at least you found the problem. Phill . . . I'm currently looking at an issue involving the MRB - I need to check if it's your MRB, a generic problem with MRBs or nothing at all to do with MRBs. I'll start a new thread, when I have more information. Dave H :D

If it's of any help (?), here's how we did it on our IDE interface:Which gives Power-on and Drive-activity in one LED (I still have some of these!).

Dave H

Don't know how it wobbles, have you lost one of four rubber feet??

If you have (?) Mark (retroClinic) stocks them . . .

I'll try to make it a 640k drive. I have several modern 3.5" drives that should do - I expect it will need a twisted cable to make it Drive 0. Would there be any advantage to a laptop drive? The advantage would be two drives :D the disadvantage is you'll need to source a suitable lead (see photos)....

My R260 needed a similar sort of repair with a dozen or so damaged tracks but it was visually obvious where the problems were - however, after a few years of working fine, it's also refusing to boot now

More corrosion, probably sneaked under the solder resist

Dave H

OK - PSU just fine - the number of engineers I've told, over the years "don't measure open circuit e.g. not loaded, supplies - you'd think I'd practice what I preach - D'oh! :oops: Just faulty drive. Ray, I can replace this with the same model of drive or let you play with alternatives - let me know...

Are you sure that the +12V being at or about +16V with the drive idle is not normal? Only with supplies that are unregulated, or regulated to another supply rail, they will tend to float at a higher voltage if there is no load. Further, I would not expect a 12V motor to necessarily die if it was su...

Ah well, I was thinking of having a Plus3 with a modern 3.5 inch drive to make it a 640K unit anyway. I can have some fun making brackets so that it fits. Ray I have some laptop drives that were for that very purpose - Not sure yet if they'll work, but if you want to experiment (?) I'll send you on...

Received the Electron and Acorn Plus 3 combination today. First look shows that the Drive is not being accessed! Step 1: Try another Plus 3 - everything works OK - so we can, probably, rule out the Electron and MRB . . . Step 2: Ray's Plus 3 back (with lid off) and measure some Voltages. This is whe...

I received last week and brand new AP5 (with ADFS Rom) and BeebSCSI. I plugged the AP5 in my Plus 1, typed *HELP, and I don’t see the ADFS Rom listed. The Rom is in slot 13. Am I doing something wrong? I haven’t tried it with the BeebSCSI attached yet. I'm arranging a View Cartridge PCB so that Ric...

Just checked this . . .

With ADFS in sideways bank 13 and no disc hardware - ADFS does not show on the start-up screen, but does show up with a *ROMS, Is this what you're seeing Ray? Dave H

Edit: No links fitted to the AP5!

Welcome to the Forum, Paul . . . Enjoy . . .

I could send you a ROM, if you wouldn't mind poping it in and seeing what transpires? Unless your software was specifically written to be backward compatible with the older ICS hardware why would you expect this to do anything useful? I can test this myself now :D see here - But no holding of breat...

Well, well, well . . . . There I was putting some caravan items away in my shed . . . And what do I spot? A pink antistatic bag with a SCART cable inside. I'm wondering what on earth is it doing there? It was among a few other items that I taken down to Wakefield. Hmmm! I thought, why has Mrs H put ...

It might be worth asking Mark, at RetroClinic, if he could do some kits for this 'upgrade'. I, or anyone else, could supply the brackets - I'll drop him a line. If he doesn't think it's worthwhile, I'll ask him if he could supply all the cables etc. and I'll hold a few kits.

Dave H

As of 45 mins ago I don’t like barrel connectors anyway, having thought I picked up a 5v psu, when it in fact 12v. The item in question is now not working. Ho hum. Time to workout what I blew up. I'm surprised these type of connectors haven't been colour coded - Can't believe the Chinese have misse...

I could send you a ROM, if you wouldn't mind poping it in and seeing what transpires?

I think we designed our board with the same 'structure' as that ...
