Is Circuit Cellar INK available to download?
We could do with the gadget described, but I have not seen INK
on UK magazine racks.

BTW, Elektor magazine had a contest for designs based on some new EPLD.
Among the winners was designs for LPT interfaced logic analysers.

I found Ciarcia's articles (when he did them for Byte magazine) were
thought-provoking although I often saw ways they could be made better
and/or cheaper. The Elektor design probably requires you to buy the PCB
and EPLDs from Elektor. Dearer than the unprogrammed part, but cheap if
you don't have to design/layout your own PCB and design the EPLD logic
and write the Windows interface program.
