Subject: Need help w/old Altair HD controller

[Pardon the wide distribution but not everyone gets both lists]

Hello Netland...

     I'm the lucky recipient of *three* old Altair/Pertec hard disk
subsystems.. It looks like 5 MB removable/5 MB fixed.  I have the
calibration disk and a full manual for the drives.

     The MITS controllers were included and I am totally mystified by
them even though I have the manual and am of a technical bent.  Would
anyone out there knowing something about this thing send me e-mail?

Thanks in Advance 
Mark

For the curious - the drives are Pertec D34xx-series, top-loading
drives, using 14-inch platters.  They spin at 2,400 RPM and, when
spinning, sound like a DP-center of 10-15 years ago.
