[HECnet] Raspberry Pi + SIMH VAX?

[Joe Ferraro]

Ah very cool...   should make the bridging easy...

The zipit is/was, I believe, 300MHz or so out of the box... but only 32MB of RAM if i recall. It was a bit slow perhaps, but certainly felt more like lower-end "real" hardware as compared to simh on a newer machine (which can obviously turn blazingly-fast "VAX" i/o in the right configuration). 

I'd seen talk (perhaps by Sampsa in this group), of an fpga turned PDP, that sounded very interesting as well... I don't suppose anyone has seen this come about?

The one issue I had was getting the bridge to work over wifi - I didn't have time (at the time) to tinker...

Yes, the pi is an ARM processor, with 256 MB of RAM.   It doesn't have wifi, but it does (in the "B" model) have 10/100 Ethernet.
