I have two things that I hope someone can identify. One is an item in
a 10-year-old office furniture catalog. It's the desk being
advertised, but the computer is of interest. Could be a prop, but I
doubt it. THe rest of the computers in the catalog are mostly XTs.
The pictures are:

www.geocities.com/researchtriangle/facility/2840/bell2.tiff
If people can't read TIFF, I'll convert them to JPEG. The other thing
is an Apple II card. It has a big red switch on the back, and has
8 sockets. It's labelled Apple ROM card, and has ROMs with numbers:
341-0016-00
3410001-00 3410002-00 3410003-00
C48037
They're all in a row, several sockets are empty. Anyone know what this
card does?

It's an Integer BASIC ROM card, for use in an Apple ][+. The same card
with a set of six (different) ROMs would be an Applesoft BASIC card for
an Apple ][. The red switch selects which ROM set will be active after
a reset, but software can override it (i.e., the DOS "INT" and "FP"
commands).
There was an optional "Programmer's Aid #1" ROM from Apple that could be
installed in one of the empty sockets of the Integer BASIC ROM card (or
on the motherboard of an Apple ][). There were some third-party ROMs
that used the other socket.
Once cheap clones of the Language Card became commonly avaialable, most
people dumped their ROM cards, since the Language Card could be used for
whichever version of BASIC you needed. On a DOS 3.3 Master diskette, the
appropriate ROM images are in the files INTBASIC and FPBASIC.
