I guess that depends on what you want to use it for. If you want to
toggle in small programs and learn how the thing works, a couple of
hundred words would be more than enough. While 128K words isn't much in
modern terms, it's plenty to do some really interesting things.

In your situation, I'd start toggling in some programs and see what it

Actually, the machine is usable in it's current configuration. Once
again, it depends on what you want to use it for.

Finding a 2648A terminal with cartridges and software properly
configured for your machine will not be easy. IMHO, The easiest way to
boot the computer from an external device is to use the BACI board and
upload programs serially from a PC.

Toggle in a few instructions on the front panel, establish a serial link
from the PC, and upload the program. Can't get much simpler than that.
Although, I did have to write a program on my Linux box to upload the

Check the BOOT ROMS (below the MEM cards) and see what device(s) they
are for. I'd be willing to bet one of them is for the 2648A. In that
case, you don't have to toggle in anything on the HP1000.

If you are hardware guy, you could also build a parallel interface and
upload data (programs) through the bus I/O card. I've done that as well.

Either mechanism will work.

If you want a full blown RTE machine... You've got you work cut out.

A few weeks ago, someone had a bunch of cards for sale on eBay. As I
recall, most of them were in the $30-$50 range. Not that bad a deal if
you only need one or two to get a machine running.

Check bitsavers... There is quite a bit of information about these
machines in the archive.
