Re: A series compatible KVM systems?

On the purely mechanical switched types, normally all pins are connected through. At least, that is the case for the ones that I have bought. That's helpful, I was already thinking of going down that route anyway. At the worse, if something isn't switched, then it won't be a huge job to move across...

A series compatible KVM systems?

I'm looking to put my A series machines on a KVM system. While the video side is easy, as there are plenty of VGA switches available, the keyboard side is not so straightforward, as the legacy keyboard socket is physically compatible with a PS/2 keyboard connector but not signal compatible. Due to t...

Re: Econet Bridge

Or you can use the pre-existing IP over Econet for Beebs: http://mdfs.net/Apps/Networking/EcoTCP/ I've had this working to telnet into a RiscIX server on the same Econet segment. It is a bit fiddly to set up, but seemed stable enough once I'd got it working. I probably should write up the process a...

Wanted: Econet Bridge

Hi,
Am looking to partition my Econet between the faster RiscOS and slower MOS machines, and add bridge support to my Arduino Filestore project. For this I need an Econet bridge!

I'm not bothered if it's the Acorn or SJ models, I just need something working I can develop against.

Cheers,

Re: Econet Bridge

AUN already deals with encapsulating Econet frames into UDP packets, which can be routed over any IP network. The big catch here is that a machine needs to running AUN to speak to a remote AUN network, which rules out anything not running RiscOS 3.1 or above (or RiscIX, but let's not go there). I do...

That assumes that, without the 6854, you have some alternative form of serialise/deserialise logic (with at least a couple of bytes of FIFO) so that you can operate byte by byte rather than bit by bit.
