Emmanuel,

Saw your post and thought I'll try to reach you here as my emails seem not to reach you... A few weeks back you said you'll get me the manuals you promised for the items I bought from you yet I have still not received anything. Do you think you could squeeze it in into your schedule to get me those three manuals (David Assembler EPROM Box, How to build EPROM box and How to build EPROM burner) you promised? Thanks so much in advance for your kind help and I hope all else is well with you!

Cheers

Peter

Hi

I only have the chematics of a XFunc & X-Mem: Maybe this helps:

-------------------------
| X-Mem Upper MODULE |
| |
| C B A 9 8 7 6 5 4 3 2 1 |
-------------------------
| | | | | | | | |
| | | | | | | | |

-------------------------
| X-Func Lower MODULE |
| |
| C B A 9 8 7 6 5 4 3 2 1 |
-------------------------
| | | | | | | | | | | |
| | | | | | | | | | | |

So, trippling could be:

-------------------------
| X-Mem Top MODULE |
| |
| C B A 9 8 7 6 5 4 3 2 1 |
-------------------------
| | | | | | | -- | | |
| | | | | | | | | | |

-------------------------
| X-Mem Middle MODULE |
| |
| C B A 9 8 7 6 5 4 3 2 1 |
-------------------------
| | | | | | | | --
| | | | | | | | |

-------------------------
| X-Func Lower MODULE |
| |
| C B A 9 8 7 6 5 4 3 2 1 |
-------------------------
| | | | | | | | | | | |
| | | | | | | | | | | |

As I remember, my only problem was to put all three modules into one module housing...

Cool, my chematics ;)
I will send it to you as soon as my EPROMs and Modules are here. Sorry Emmanuel

Emmanuel, there was a recent thread where I mentioned some articles from the PPC that talk about module doubling and tripling. The thread can be found here

Let me know if you do not have access to the PPC journals mentioned and I will get you a copy of the relevant pages.

Cheers

Peter

The Connection to GND is no good idea becouse the original ports are connected to Vcc or left open. I would just wire like modules are connected when inside "real" ports.

Port 1: Pin 2 open, Pin 4 open

Port 2: Pin 2 open, Pin 4 ->Vcc

Port 3: Pin 2 ->Vcc, Pin 4 open

Port 4: Pin 2 ->Vcc, Pin 4 ->Vcc

For X-Functions in the real port connect all pins to the connector.

For the first X-Memory leave pin 4 open (=left side seen from the back, Port 1 or 3).

For the second X-Memory connect pin 4 to pin 3 (=right side or Port 2/4).
