CPU or not on Parallel ATA?

Sorry pal, I didn't look to well at the photo either. Apparently, tbe board is designed for either PGA or QFP packaged CPUs, so with the QFP 386 soldered on, the PGA socket stays empty. ;-) -- Zac67 (talk) 22:42, 7 March 2015 (UTC)

Ah ha. I'd forgotten they built boards like that. That way the mobo maker could build just one board and sell it either with the AMD CPU or expect the buyer to buy one. Jeh (talk) 02:25, 8 March 2015 (UTC)

HELP! (question re. multiplexers in digital logic)

Now it is asking if one were to do it via a multipxer for Jd and Kd thru Ja and Ka and each gerated by using a multiplexer that is a 8 to 1 line multiplexer for each J and K controll. it says to write down the 8 input lines of each multiplxer, including alternatives. It says the least significant address lines is the ones and is connected to Qa and the most significant the fours, adress line is for each multiplexer is Qc. It states that Qb is connected to the twos adress lines in each case.
