I just finished installing a Quantum 80s and a 2090a for a friend. It screams -- 525K/second on Diskperf. But I wonder what it'll do with a Microbotics Hardframe -- because both the Hardframe and the Quantum support the new synchronous SCSI protocol (4mb/sec). Has anybody ever tried such a setup? Care to share the results? -- | // Eric Lee Green P.O. Box 92191, Lafayette, LA 70509 | | // ..!{ames,decwrl,mit-eddie,osu-cis}!killer!elg (318)989-9849 | | \X/ Amiga.

I haven't gotten around to diskperfing it yet (despite having had the Hardframe for 3 months), but, judging by pm's display, almost everything is CPU-bound now, which should indicate a transfer rate substantially higher than 525K/s. Anyway, it's amazingly fast. ______________________________________________________________________________ /_____/_____/_____/_____/_____/_____/_____/_____/_____/_____/_____/_____/_____/ |_____|_____|_____|_____|_____|_____|_____|_____|_____|_____|_____|_____|_____| _No dark sarcasm in the classroom|_____|_____|_____|_____|_____|_____|_____|___ |____Teachers leave the kids alone__|_____|_____|_____|_bryan@cs.utexas.edu___| ___|_____|_____|_____|_____|_____|_____|{vertebrae...}!cs.utexas.edu!bryan_|___ |_____|_____|_____|_____|_____|_____|_____|_____|_____|_____|_____|_____|_____|

Does anyone know if the Microbotics Hardframe is able to DMA into the 32-bit memory on the 2620 board? Do any controllers besides the 2090A have that ability? Bill Murphy

Care to share the results? > Well hopefully soon, I will be able to let you know how this setup works. I obtained both and was quite anxious to try it out. Installation was quite simple. The two go together rather nicely. I plugged the combo into my 2000 and started the first step of my installation. Unfortuanately the first step failed. I got an error message stating no drive present on the Hard Frame. Himmm....I had an ST embedded ICD FA-ST Hard Drive setup and thought maybe I could verify whether the Quantum was the culprit or the Hard Frame. Unfortunately the ICD setup had no formatting prgs that would work with the Quatum. I tried one and it said no drive. Himmm...I thought, must be the drive so I sent it back. GVP was the supplier and they replied very quickly telling me the drive checked out fine. Well now I had to send the Hard Frame back to have Microbotics check it out. They refused to swap controllers with the dealer and insisted on testing my unit out. Well I sent it in an am waiting to find out the results. Hopefully they will find it faulty and send me a good one soon. I will post a follow up along with how well they work together...Any one else out there experience similar problems?? Matt Hetman
