Options other than ispMACH4k?

Starting in Nov 2020, Lattice now wants $600 a year for ispLEVER, which is the only tool for working with the ispMACH4k parts, as far as I'm aware.

Are there other options, especially for replacing smaller chips (like SOIC24 and such)?

The smallest MAX7000/ATF15xx parts seem to be just a bit large. MAX3000 looks large too.

Unfortunately there aren't many 5V or at least 5V-tolerant CPLDs still available nowadays. After that little surprise from Lattice, I had to install ispLEVER in a VM with the date set to 2010 to trick it into thinking the license is still valid. Dirty solution for a dirty decision, but it works and the parts are still quite cheap...

MAX7000's were available in QFP100 packages I believe, but they aren't produced anymore. Atmel CPLDs would be the next best solution IMO.

I'm not aware of any PLD that would physically fit in a SOIC24 footprint.

I think a mach4k v in 48tqfp would have just barely fit on an interface pcb, but sadly I missed out on being able to get the software.
