I would say yes. The ATmega8 has 8K of flash memory. My AmForth 6.8 ATmega328p hex needs ~10K of flash memory. It might be possible to remove words from the current distribution/build so that it would fit into 8K, but then there would be very little flash memory remaining to do anything with. >From a search of the mailing list, 2.7 was the latest version I saw reported as running on an ATmega8.
