The two chips named pal16L8 needs 210mA each and the little Ram 50mA That means around 500mA required for the Protek interface, I think it's too much to be added with the 250mA for Erebus and 650mA for the Oric computer. Yes too much, but the PAL16L8 c...

I perfectly understand you, Silicebit.

... there's no way to get working simultaneously my Cumana reborn and a joystick interface on the same port.......

Re: IJK interface diagrams.

... Dbug (because he showed interest) and - if interested - kenneth and Silicebit. (for their help with the interface) would have priority on the waiting list. So only one unit would remain for someone else... Thank you very much for your offer, HigashiJun, but I'm more interested in the Protek pro...
