First off, I'd like to thank those of you who have replied to me directly in connection with my first inquiry about BMS 200 and SCSI hard drives. It seems to me that it is easier to go without the intermediate step of using something like the Adaptec400 to be able to use st506 drives...probably easier to put together and probably cheaper. Now, I'm going to throw a twist into my original question. I am really interested in getting a hard drive to use with a mac emulator. Right now I have the MagicSac and am considering moving up to Spectre. The thing is, if I build one of these BMS 200 + SCSI drive systems, will it work with the Magic Sac and/or Spectre128. I have seen Dave Small's recent gadgets newsletter where he says Spectre now works with Seagate 277N and 296N SCSI drives, but what about with the MagicSac? Does anyone out there have any experience with a MagicSac running off a SCSI hard drive system? And not necessarily with a Seagate...what about Micropolis? or Miniscribe? I think I've found some decent prices in Computer Shopper, but would hate to put the thing together to find out that it won't work with the MagicSac. Also, what about these drives with the Spectre? Anyone have BMS 200 + SCSI (other than Seagates, which I've read alrady work) on the Spectr? (Dan, can you help with any of this?) As always, thanks again in advance for your helpful advice. ---Gerry maxg@suvm.bitnet ggreenbe@rodan.acs.syr.edu

Most of the time you will have no problems but occasionally you will get "unable to write file skip or continue" messages. This happens most often when copying large files to/from the hard disk when lots of SCSI i/o is occuring. Spectre version 1.9 adds the "slow SCSI" option which fixes this problem. > And not necessarily with a Seagate...what about > Micropolis? or Miniscribe? I've only heard of problems with integral SCSI drives and then only with Seagates. I've never seen any problems with seperate controller and drive setups, in fact Dave uses an Adaptec 4070 RLL controller with a 277R. > Also, what about these drives > with the Spectre?

The differences are features (pass thrus, clocks, etc.) and quality (some of the ST interfaces are real junk). The only drive interface that is incompatible with the Magic Sac and the Spectre is the Haba drive. Since they haven't been sold in 3 or 4 years very few people care.
