I've run out of SCSI IDs and do need another SCSI bus into this here IIfx. Support for parity (the normal A/UX SCSI driver doesn't use it, much less the MacOS SCSI Manager) and DMA (required!) would also be a good idea. Prices, and possibly the name of the German distributor..? I'd try and get the information myself, but from Germany this tends to be hideously expensive (can't call 800 numbers, the phone rates for int'l calls from here are among the highest in the world, and my budget is very limited already). aTdHvAaNnKcSe, and all that. -- Matthias Urlichs -- urlichs@smurf.sub.org -- urlichs@smurf.ira.uka.de /(o\ Humboldtstrasse 7 - 7500 Karlsruhe 1 - FRG -- +49+721+621127(0700-2330) \o)/
