Re: Double Xmem module for HP-41 Message #3 Posted by Diego Diaz on 18 Feb 2004, 10:16 a.m., in response to message #2 by Meindert Kuipers
Hi Miki,
Just to point out a different approach, (which I used in my own double X-Mem)
As for Meindert's config, you always get your X-Mem modules into PORTS [1 + 2] regardless of the port you physically connect your module.
You may want to keep some "fexibility", being able to choose between ports [1 + 2] or [3 + 4] depending on wich port you physically plug your double module in. Just connect B4 line to the connector strap, and put one module's B3 to GND while keeping the other's B3 tied to V+.
With these config you'll find your memory at ports 1 & 2 when plugged at ports 1 *or* 2. (obviously same scheme for ports 3 & 4).
Wichever approach you choose, please let us participate of your success!!! ;-))
Best wishes.
Diego.
