  OK Thanks. Are the BASIC commands on the 4052 the same as the 4051?
FWIW the 4052s use similar plug in ROMs. One of the manuals that I have
shows the same function ROM for the 4052. It uses the same case but a
different board with more ROM ICs on it.

  I'm like to see the marketing info. Where did you find it?

  I've been cleaning the 4051 up today. Man, is it filthy! There are dirt
dobber nests all through it. I cleaned up one of the 4097s and checked the
power supply. It spun up but one voltage is slightly high. I have to fix
that.

  Here's a rough list of what I have: Tek 4051 mod 1,22 (what is a mod
1,22?). A 4097 8" disk drive with a single drive. It has option 031. I
don't know what that is unless it's the connector for the second drive. It
has an HP-IB port for the controller and a 40 conductor ribbon cable that
connects to the other 4097. The second 4097 has two 8" disk drives and no
controller port just a connector for the 40 conductor cable. There is a
Data Communications Interface on the back of the 4051, it has two ROM
sockets in it and a RS-232 port on the bottom. There is also a ROM
Expansion box (4051E01). It has 8 ROM sockets and a cable with a dummy ROM
that plugs into one of the ROM sockets on the 4051. I have five ROMs in
it; File Manager, Editor, Signal Processing, Service Pack and Binary
Program Loader. I'm supposed to get some manuals from the seller. I took a
quick look at them and there was a 4097 manual. I didn't look at the
others. I did pick up manuals from someone else for the Signal Processing
ROM and FFT ROM (I don't have that one). There are two connectors on the
top back of the 4051. I don't know what they're for except that one has a
note not to connect the joy stick unless the machine is off, so I assume
that's what it's for. I think the other is for a printer.

  Thanks, I'm sure I'll have lots of questions once I get this thing fired up.
