PCIF

[curtis]

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.

This is the "modern replacement" as of right now

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.
