Yes, that's a valid criticism of my idea.

However, I would venture to argue in its favour along these lines: when you have a major project in hand (like, say, building an IBM System/360), it can be very useful to tap an occasional 8-bit hex display into your bus to see what's going on. But it's ...

What a brilliant program. Thank you so much for sharing it with us.

Of course, when you love something, all kinds of ideas come up for "improvements". Here are my first two (groan):

1. A three-colours plus off variant of the LED, with either a two-bit input or two separate 1-bit inputs. 00 = Off ...

For anyone who's interested, here's an experimental set of chips to tinker at.

It provides 1-bit LFSRs with a tap signal, in both the Fibonacci and Galois configurations. These chips carry both the main shift line and the loopback, so they can be plugged end-to-end to make wider shift registers ...
