Hardware is complete - I've sent out some fixed up 2.4 boards - not sure if anyone's built them yet?

Edit2: Out of interest, how are you powering the drive (sorry if you've answered this already)?

This one. Very this one.

I've been using these for the most part:

I'm really confused as to the problem you're having - I've used loads of different memory sticks and they've all been fine.

3.5 is useful for pushing a sensible set of CMOS settings in there I use 3.2 with the Y2k fix for the most part. Again, sometimes 1.2 for games if they're not behaving.

Hello there

Welp, you can ask for £30 and see if anyone bites..? I know sometimes things go for less than we'd like, but the value of anything is only what anyone's prepared to pay for it at any given time.

d.

£17.50?

Other sold prices seem to be around the same, in the UK and the US.

Hello! Welcome to the forum! You still need to kill off any hydroxide left there or it'll continue eating away at stuff. Just use the vinegar neat :) - no need to dilute. If you're not in a soft water area, do use deionised or distilled water to rinse the board off after the vinegar. Once you've got...

Don't worry
Paul is indeed PaulV and MartinB is MartinB. MartinB may or may not be real, but evidence strongly suggests he is, even without his data having been hoarded by a multinational advertising corporation.

Who are you again?

OK, if I forget give me a nudge.

Yes, but not sure when I'll get a chance! Will probably end up near a timpsons at some point this week

And Napalm.

I'm about to reverse engineer a Victor 9000 hard disk DMA board, it's rare as hen's teeth so whilst I might use braid for cleaning holes out, I'm going to use the right tool for the job on this one!

Or you can just load it into kicad and take the measurements from there. It'll probably be quicker than waiting for me to get around to it.

PCB dimensions were:
width : 40.69 mm
height : 53.39 mm

Not in a position to measure anything else at the mo (that's from the order, I'm at work) - the height will entirely depend on the size of pin headers you decide to use.

Pretty bloody brilliant frankly...

Because it's actually better, Colin

With the MRB, in turbo mode, it uses OS3.0 rather than 1.2.

d.

I can give this a shot (also have an original MRB) - but it might be a bit before I get things rearranged to test!
d.

Nope.

Finished version:

I'm really not getting into building them for sale I'm afraid Of course, anyone is free to make them or people could club together and buy the bits to make it a bit cheaper? I just don't really want to get caught up building loads of these and then having to support/repair etc...

d.

I can confirm that version 2.5 of the board (as is currently in the repository) works perfectly. I've got a version of the zimodem firmware (more fully featured, but still needs a bit of tweaking) in my github that I've set up to work with this hardware, or the firmware in the esp8266 stardot repo c...

Electron is either ULA or Memory (they don't have a 6522 in them unless you've plugged one in on a cartridge or something) - and as Duncan says, the keys are just dirty keyswitches.

If you swap the ULAs and it still white-screens, it's most likely to be one of the 4164 DRAMs.

Welcome Chris - 2001 is pretty late to still have a beeb in the classroom! Econet should be within your grasp, and you'll certainly have help getting the other machines up-and-running here

How are you formatting the USB stick? It does seem most likely its something on your end rather than the gotek?
