Does anyone have any infor on the Prestor PS180-16F at/386 controller. I am considering purchasing this with a 71 MB miniscribe MFM drive. Have there been problems with such an arrangement? Has there been success with this ? Any software not run or any disk problems?

I ran the PS-180 (hard disk only) with TS4096 and ST251 drives. It worked well, but it did not work with Xenix or UNIX. The version which does both hard and floppy is supposed to do this. I *believe* that the track buffering in this controller is done by software in the BIOS. That means it will run 1:1 for DOS, but probably 2:1 for UNIX. I only ran it for a few days, but I was reading and writing files for 24 hours of that, with a batchfile driving a database prog, and I didn't have any problems. -- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) "The world is filled with fools.

I have been using the Perstor model PS180-16FN in a 16MHz, PCDesigns, 386 box with a Miniscribe 3085 for about 6 weeks. It requires 2:1 interleave, and the data transfer rate is just a little faster than with the previous 2:1 MFM controller it was on. There have been no problems so far that I can trace to the controller, but the machine has given some problems on power on, and once gave a "floppy drive controller failure" error message. This has not happened for two weeks, and I do not know if the controller was the cause of the message or not. khc@eecea.eece.ksu.edu
