Thomas Henry's SuperSeque used a 4-bit up/down counter, the CD4516,
and a 4-bit decoder, the CD4514. You can still find those ICs.
The SuperSeque plans were published in Polyphony, which tells you how
old the design is. :-) There was no PCB layout; Thomas said that he
used point-to-point wiring. (I actually have the old magazines, but
I'd need some time to find the right issues. It was a 2-part article
and some errata could have been published in a later issue.)
