WTD - Acorn A4 Econet card (ALA66)

Post by philpem » Thu May 14, 2020 2:36 pm

Is anyone looking to part with an ALA66 Econet interface card (and ideally the special Econet cable too)?

I'm setting up an Econet and it'd be nice to have the A4 on there too!

Cheers,
Phil

Can't help I'm afraid but I was looking for one of the (internal) cables years back and never did get one. I meant to build one but never did get round to sorting it. I seem to remember stuggling sourcing the cable ends. I must revisit that.

I think CJE sometimes have them, although I can't see one listed just now.

I wonder if an adapter could be made to take a standard Econet module, I haven't looked into it but presumably it's the same or very similar signals on the 17 pins of the normal module which would go to the A4 internal connector, and the 5 pins just go straight to the Econet lead.

The difficulties are the limited space available in the upgrade bay, making up the mounting bracket, and getting hold of a 2mm I/O connector (which I'm not certain has ever been identified...)

Of course there's nothing stopping you cloning the PCB and doing it with surface-mount parts. Just that if I was going to that much trouble, I'd probably make an Ethernet card instead.

Putting the A4 on the Econet is a bit of a 'wouldn't it be great if' project for me, now I've had the Master and A3000 talking to each other.

Just heard back from CJE. They sold out of them "many years ago" :(

Back on the hunt!

They're hen's teeth mixed with unicorn poo. I've pondered that the best option is some sort of extension lead that brings the header pins out of the A4 case to a standard Econet card.

I loved my A4 when I was in Hong Kong. Could program away on it over the weekend, then back at work, plug into network, copy everything into URD on the server.
