Re: For sale: Acorn Electron WiFi cartridges

Do we know if anyone on here can print a case for these boards?

Happy to pay as have no way to make a case myself.

Thanks

Re: Raspberry Pi 400

I like this

I also like how some people are now looking at pcie 1x connector on new computer module and have sata adapters running and some good signs they may get gfx cards running. It at least opens up some desktop storage options

Re: Electron Plus 3, some questions.

While we are talking about plus 3 I am sure the rom/ram upgrade available from Dave H (canny remember which of our members makes it but was one of usual suspects).

It gives you access to ADFS and DFS at &E00

Re: Electron Watchdog? (Soak tester)

So we any idea what it does, does it short anything or send anything to elk to make it carry out the soak test?

Still to try plugging it in to see how long LED’s change or light up go out etc before it appears to settle.

Re: Electron Watchdog? (Soak tester)

Apart from the fact the literature indicates it takes a set length of time to run the soak test and it was designed so it could be soak tested without someone sitting over the machine then I have got to guess it does something more then just monitoring IRQ I will plug it in at some point and monitor...

Re: Electron Watchdog? (Soak tester)

Says soak tester maybe it came with software that loaded the elk. Would have expected that to at least be in rom though

Re: Electron Watchdog? (Soak tester)

Maybe it isn’t actually a tester but circuit that can put elk into a soak testing mode and somehow via irq flag the led’s

Re: Could you plug a pi into a matter cartridge slot?

On elk I imagine it could do 1mhz bus and tune pi as both buses were avail as cartridges. In master I am less sure as they already have those buses so may clash with same on cartridge?

Re: Electron Watchdog? (Soak tester)

Aparently an electron Soak tester according to electron service manual. Used to identify intermittent faults.

Guess it puts elk under full load and looks for faults somehow.

Could maybe be a good test device for some of the ULA replacement projects.

Imho areas can be larger than one screen so change palette to represent area changes would make quite a bit of sense.

Re: Why was BBC BASIC so fast?

Good hardware, very very well optimised basic etc etc There were quite a few benchmarks where bbc micro could better the ST and Amiga. Especially ones designed to test how good the basic interpreter was. I believe there was 1 other 8 bit machine with a well optimised basic in rom that was as fast if...

Re: Here are some scans of the Barson computers Electron Econet interface CCT and blank board

Nice,

Messaged a while back asking if he could maybe scan the board (I see how he can’t reply) least we have the scans which by sounds of it may make it reasonably doable to have a cartridge that will do econet or take a master/a3000 module.

Brilliant.
