Pete,
Not having the benefit of decent chemistry knowledge, I tend to avoid using
solvents and detergents on delicate items, especially ones that have
collectibility or vintage value.
I don't know enough about the effects of using certain chemicals on the
various plastics and expoxies used in the manufacture of the boards, so I
steer clear of using a detergent unless I know that it would be perfectly fine.
My experience has been that with certain devices that spend entire lives
inside, that usually a rinse with hot water makes them look new. I've been
satisfied with just using hot water, and everything looks nearly new when
complete.
Just a precaution I mention without having experience with detergents.....

Many thanks for this tagline to a fellow RGVAC'er...

New subject: Ampro Little Board questions...
A couple of things...
I've got an Ampro Series 100 enclosure that has a really mangled floppy
cable. I seriously doubt that the cable I got with it is the one that
belongs with it. Does anyone have a Series 100 box that could give me
the measurements and connector orientation & location of the floppy
cable?
Secondly, I don't know what "brand" SCSI controller is built into the
board. The SCSI chip seems to be an NCR 5830, but that leads me nowhere
in relation to whether or not it's an Adaptec or other model controller.
I need to know the brand because the hd formatting software needs to
know it.
Thanks!

New subject: Ampro Little Board questions...
AFAIK, the AMPRO boxes were just pieces of sheet metal, hence didn't have any
effect on the floppy cables at all. Before the IBM PC, floppy cables were flat
ribbon cables with, in the case of the AMPRO Little Board with which I'm
familiar, there was a 34-contact PCB socket on each end of the cable.
The SCSI adapter is not part of the AMPRO Little Board, but, rather, is a
separate board about the same size as the Little Board, which is a bridge board.
In some cases, according to what I've read, the Little-Board <=> SCSI-adapter,
of which there are 2-3 implementations, can talk directly to some drives via
some adapters without any additional prep, but may require a format routine in
most cases and a prep (with which it writes the information on the drive, so
that it can identify it next time) in any case.
IIRC, the XEBEC 1410 was a common board in this application and was the only one
I've ever seen in one of their "bookshelf" systems. Several others are
supported, however.
You'll probably have to look inside the box to see whether there's a bridge
controller, and whose and which model it is. If there's no bridge controller,
the drive is one of the early models with the integrated controller on board.
Don Maslin sent me the information I have stashed somewhere I can't locate at
the moment, but it identifies and describes procedures and models to which they
apply, albeit within their listings, for the most part.
