Hi, Guest
Hi
Wondering if anyone reading this can walk me through handling decoding address lines on the TI.
Looking to possibly add a A/D convertor for example.
I assume I would have to use something like a 74ls138 decoder but not sure how to use the truth table to address the ti memory, say at the end of expansion memory.
Exactly how can I place data at a specific address block?
If someone out there has any examples of how this was done? write ups etc
Please share them.
Years ago there was a clock/ A/D card that did this for example.
( couldn't find a schematic)
I don't know if anyone did a write up on this, in detail .
