Thanks. Yes, the web (my link above) has the installation instructions, requirements and so.
I use it with my A1200 ACA1230/56/Fast ATA/Indi MKII and also with another with just an ACA1230/42.
I can't promise a date, but I'll try and get it running on my A4000 rig:
68040, Fast ATA 4000, Mediator with 256MB Radeon, Deneb, Spider, SB128, etc
It is running a ClassicWB 3.9 based install at the moment, so it will be interesting to compare them.
