Diag Board and Simple 8bit IDE IF

Hello,

finally I have made it. After finishing Winston's Diag Board a few days ago I started yesterday building the 8 bit IDE Interface from Peras site.
Gave me some trouble and I stopped this morning at 2:30 am, because office time started at 8:00 am. But now found the mistake and it works great. Have already copied some games and the loading time is incredible fast.
I want to add a NMI and a reset button and than the "super" rubber 48k Speccy is perfect.
Thanks to Pera and Winston!

Regards

Stephan (now playing some games;-))

P.S. is somewhere around here a PCB layout for building a spectrum edge connector expansion? To connect morde then one IF?

    I have a layout for an edge connector breakout board with a thru port, but I suspect that's not what you're after (the breakout board is to allow breadboard prototyping by plugging in breadboard jumper wires into the SIL strips that are soldered onto it).

    Hi Winston,

    thanks, but this is not what I am looking for.
    Lets assume I have three speccy interfaces without edge connector feed through but they are in principle compatible. I look for a device which allows to connect all three IF.

    Try the Sintech website. You might find an expander that allows you to connect two interfaces at once, but I doubt you'll be able to find one to connect three.

    Other two things you should consider:

    1-Some interfaces might not work when connected at the same time, if they use the same lines, ports, etc.
    2-There is a limit on the amount of current that you can draw from the Speccy.

    I don't know how to explain the technical details.

    Thanks for the hint to the sintech homepage. It came not in my mind that such things are easy availible.

    I use pc power supply to power up my speccy for several resons. First I need it to power the hard disc and additional I got rid of this TR4/TR5/coil technique. But also there is negative things, I need different heat source to keep my cup of tea warm.

    Indeed some IF are still incompatible. Neverless I will give the sintech bus expander a chance, its cheap and I can try sintech support.

    Regards Stephan
