Interesting! I had the same idea. Have you got a PCB design for an Econet module?Kazzie wrote: ↑Sat Jul 18, 2020 7:21 pmWe seem to be crossing paths quite a bit at the moment. I've just ordered some VRAM chips following your successful build (and parts link), and I've also spent this past week considering getting some of those EF68B54s to make a batch of econet modules, having baulked at the current going price for modules!
I was going to design a Podule and a module.
As the 26LS30 is obsolete, I was planning to "borrow" the line driver circuitry Myelin designed for his "Econet from scratch" project, and use the old Acorn opamp line receiver.
Agreed that the going rate for the modules is getting a bit silly, long gone are the days of £10 Econet modules it seems...
