I am looking for a TI PCIF for the TI-74/95.

 

Anybody got one they'd be willing to part with for a price?

 

Or anyone know where I can find one?

Is there a schematic available?  Maybe someone could wire one up.

That's the software side. 

 

How about the hardware side?

 

And yes to Brain, there is a schematic on wht, but my eyes have gotten to the point I can't do any fine soldering.

 

Ya know, getting old REALLY SUCKS!!!!

Thanks, but I've already got that.  It's just that my eyes have gotten so bad I can't see fine enough to do the soldering anymore.

 

Like I said, getting old sucks and it ain't for wimps!

I'd lay it out with ExpressPCB, but I just don't have the time right now.  I know brain (Jim Brain) was working on the SD card Hexbus peripheral.  I wonder if we can maybe put a USB compatible PCIF that will work with the third party software above on his board as well?

 

Also, while we're talking about the 74.  I seem to remember that the 74S can address more with CALL ADDMEM (16K) than the TI-74 could.  However, I can't find my source for that.  I just know the fact somehow because I read it somewhere.  :)
