Yeah, I also got an M-Tec (well, a Viper actually) with 4 Mb Fast.
4 Megs are a bit tight, but I find it a fun challenge making the system do everything I want with so little ram. :-)
Sadly, I need the PCMCIA for the ethernet card, so 8 MB were out of the question...
I very much doubt Jens is ever going to release his 030 accelerator. I had preordered one ages ago before it was cancelled... :-(
