An oops moment.

After making my last post, and doing a bit more research, I found a 3-8 decoder that doesn’t invert the output (74HC238).  I purchased some of these and will use them in the 16 row builds.  I should be able to drive the display directly with these w/o needing the octal inverters.

Oh well, I’ll have some spare parts to mess with in the future when my original 74hc138’s and inverters arrive.  😀

I also have placed the order for 2 more displays they should arrive around 7/26.  So maybe by next weekend sometime I’ll be able to have a 16 x 80 running.  (fingers crossed)

That’s all for now…
