<DIV><FONT face=Arial size=2>Well, I had considerable experience with the 5100's
in the late 60-early 70s. The IL Dept. of Ed was still working loosely with the
remnants of MPATI and a program called "Early Bird" where WILL-TV in Urbana, IL
transmit in-classroom materials between midnight and 5am. Our office put about
50 VTRs in various schools with timers so the teachers could play back programs
during the class day. Failed machines would get local service or be
brought back to the Springfield studios for repair. Our problems were almost
exclusively head-clogs. The component failure rate was actually very low -
and the interchange rate was fairly high. Boy, was that a long time ago. Still
have a service manual for it. And yes, the head was a pancake motor,
but the reels were belted.</FONT></DIV>

<DIV>Lastly the moveable guides never held interchange. Be prepared to
adjust the guides on almost any old tapes. Also the top edge guide on
these arms would get cuts in them that will do edge damage to the
tape. It is wish you luck on good interchange.</DIV>

<DIV>Don Norwood can offer some comments on recovering Type A tapes using his
VR-7900.</DIV>
<DIV><BR></DIV>
<DIV>Interchange on Type A machines was the motivation for Ampex to develop
"Automatic Scan Tracking" (AST) using piezoelectric elements to support the
head and enable it to move and follow the track, as outlined on a number
of occasions by one of the developers, Jim Wheeler. Ray Ravizza was his
engineering colleague on the project.</DIV>
<DIV><BR></DIV>
<DIV>Their method is outlined here:</DIV>

<DIV><BR></DIV>
<DIV>The first first production machine to use the new AST was the Ampex VPR-1
(Type A) which morphed into the VPR-2 when the SMPTE Type C standard was
adopted. </DIV>
<DIV><BR></DIV>
<DIV>Ampex made retrofit kits for the VPR-1 to make them Type C machines. Some
unconverted Type A VPR-1s exist, and are sought after.</DIV>
