I am not even sure that this is meant for this particular computer, or
this tape controller. I also am confused by the last command, since it
doesn't have a memory location. Thanks to some help from Fred N. van
Kempen, I was able to type it in (I have to type <memory
location>/<contents> - before I was trying to type them in separated by
a space). After I typed in the program, I typed 2000G, and it just
hung, the RUN light on. Pressing Break on the terminal stopped it, and
it printed 2026 on the screen. While the program is running, the LED on
the tape controller is lit, but the tape drive doesn't spin or do
anything. (And yes, I do have a bootable tape loaded, and the tape
drive set to online). I don't know for sure that I have the tape drive
connected right though.
Guaranteed there is someone on the list that is an
active
11/73 user. I want to be one, but I'm not there yet.
Thanks. It was really cool to see that prompt... I had been trying to
plug the terminal into channel 0 on the card, figuring that the console
would need to be on the first port, but then I found the information in
the interfaces handbook, and found that it needed to be on channel 3,
and I also was able to read the wire jumpers, and figure out how the
board was configured.
Powering it up gives me the @ prompt.
Look for your KDJ11 manual**, chapter 3, for ODT. That's
the lanuage thats expected over your serial line (Working?
Congratulatations! BTW). I have a tape boot program here, on a piece of
paper,
but I don't know how to type in the values.
What does it look like? Numbers, Mnemonics? How many lines?
Also look around for any ROMS not on the SMD,Pertec
controllers.
These could contain a bootstrap you can activate. Write down any
information that may be pasted on these ROMs. It's also possible
the controllers' ROMS can start a CPU bootstrap directly too.
In any case, Your supplier, Wayne was a turn-key systems VAR
(value added reseller). I would almost expect your system to be
a turn-key one right now.
If I don't type the program in, and just turn on the system and flip
the Boot switch, the LED on the tape controller flashes briefly. I
don't see any ROMS, there is an empty socket on the CPU card where a
ROM might be able to go, and the ROMS on the tape controller are
factory made (not EPROMS that may have been added later) Maybe I should
install the hard disk controller? Right now it just has the CPU card,
serial card, RAM card and the tape controller in it. What other
configurations do I need to do to get it to recognize the drive
controller? From what I have been able to tell, in the PDP-11, the
order of the cards matters, and their addresses need to be set
manually, right? How to do this, I'm not sure.
Last weekend was a big breakthrough. In less that 24 hours you
amassed a total system that I have spent many weeks over a
period of many years collecting. Wow! Another BTW, these
systems used to be sold for $85,000 each!
Yeah, I really love this system, and I'm really glad I was able to get
it. I've got a lot to learn about it, but I'm really looking forward to
getting it booting and running something. I haven't decided what OS I
want to run on this thing though, I have the boot tape for RSX, but it
should also be able to run RT11 and UNIX. Any others? What other
software is available?
Thanks!
