HP 1000 ROMs (HP newbie, be nice!)

I have an HP1000E/2113B, s/n 2130A00623 sitting in my family room. I've run it to see the lights blink but don't know anything else about it. How would I check to see the ROM configuration? Configuration includes 12821A disc controller, BACI, HS terminal, BUS I/O and a bunch of I/O cards, also 3 64K word memory cards. I don't have docs for this box but I have what looks like a complete set of manuals for a truly embedded system - an HP 5987A GC/MS (gas chromatography/mass spectrometer) system. Manuals include the RTE-6/VM manual. I bought manuals and cables; the CPU itself may still be available (I think asking price was $300) if anyone is interested. BTW, this thing is really too big for my collection - anyone want to trade a MOS KIM or Exorciser system for it? Jack Rubin Wilmette, Illinois USA
