Oh yes sure. I am also bringing my FPGAtom.
There will probably more 8bit computers.

@Timo: can you reserve some tables for us?
I think we can find you a table if I know you will be there. How many tables do you need ?

Even though it is billed as a RISC OS eXperience, would there be interest in my bringing my replica Atom along?
Yes, a very good idea. Every Acorn computer ( or its replica ) is welcome. Most welcome

Re: $70 100MHz (?????) 'scope

Some calculations: square waves the upper specified frequency of your scope should be 10 times. The official frequency of the Archimedes is 24 MHz so 250 MHz would be much better. Further to this, it looks more like a single channel oscilloscope which is perhaps a bit limited to do really useful wor...

Re: Purchased a RiscPC from ebay and need help on how to get it working

Remove the battery immediately it will eat up your RISC-PC. Removing now is more important than having a replacement ready. You can use a small box to house two batteries or use a replacement Varta. You could start with pressing 'Delete' while powering up and then see what happens. It could be the c...
