Re: Redesign Electron Plus1

Re: Model B paged ROM breakout board. Interest?

Yes sure I am happy to publicise all that the details that I have. Unfortunately I had a bit of an accident with the project folder and I appear to have lost all trace of the most recent one from which that board was made. The hardware is all in kicad.

Re: Model B paged ROM breakout board. Interest?

I would like to an option for a DS1315 chip and two of the sockets as 32 Pin ones. A 128K Flash chip in one and 128K SRAM in the other would be awesome and the chips are available and very cheap now.

I assume from your post that you have an original Econet NIC with non-Strong Arm Compatible boot ROM and you are using a Strong Arm with RO4.39?

Re: Econet podule for RISCPC & A7000

Ian, thank you very much for the new drivers for the RPC Econet mini podule. (I signed up here just to say that) I have it installed on 4.39 so the location was slightly different. So far its working perfectly with !awServer and my Beeb & Compact for probably the first time in 10 years. My machi...
