There seem to be two kinds of hard disk controller for the Amiga: SCSI and ST506. I've been told that SCSI has a much greater transfer rate than does 506, but that I'm unlikely to see much benefit from that unless I have a controller with DMA. Apparently there aren't any 1000 controllers with DMA? But there are a number of companies working on expansion boxes for the 1000 that will accept A2000 cards. I'd like any information you care to provide on this whole situation, but particularly: Are there really no SCSI controllers with DMA for the 1000? Why not? Will 2000-compatible cards plugged into the new expansion boxes be "crippled" somehow because they're not really directly on a 2000 bus? (And if not, I really don't understand why somebody hasn't done one directly for the 1000.) Thanks for any info or discussion you can provide. -- Robert Reynolds uucp: ... !gatech!hubcap!robert CS Dept, Clemson Univ.

(And if not, I really don't understand why somebody > hasn't done one directly for the 1000.) There was one box I saw at AmiEXPO, and I asked to be put on ASDG's mailing list for their 2000+1 box.. The one I saw was called the "Bus Expander".. it was in a PC-clone case with a PC-clone power supply, didn't have the CPU slot the 2000 has, and I don't remember seeing a monitor slot either (no mention in the add of course).. They do claim the 2088 bridgecard works though. I asked about ASDG's box, and found out that it will be out RSN.. whatever that means :-) so I didn't bother to ask about info but got on their mailing list. I believe ASDG's box will have CPU slot, etc.. but I won't know till I get the literature on it. There are probably more, but that's all I saw. -- Pat White ARPA/UUCP: j.cc.purdue.edu!ain BITNET: PATWHITE@PURCCVM PHONE: (317) 743-8421 U.S. Mail: 320 Brown St. apt. 406, West Lafayette, IN 47906
