Hi. I'm curious if anyone's got RTE-M booting from mini-cartridge (such
as 2645A terminal) or 8" floppy (such as 9885M) for their HP 1000 21MX
(eg. 2113E).
I'm attempting restoration of a 2113E with the extremely kind assistance
of J. David Bryan, and would love to find a bootable primary copy.
It would also be great to hear what OSes folks are running on these, and
which version they like the best.
Thanks very much,
John Singleton

Hm, I've never tried RTE-M, although I have rev. 2140 on magtape. Instead,
I prefer RTE-6/VM on the 1000F. I have a setup with a 7905 (shared in a
multi-cpu configuration with a HP 2100S), a 7970B, a 7970E, a 9122C, a
7958B (system disk), 2648 on a BACI and a terminal server on all the ports
of an 8-channel MUX. Lovely system, and very different from most modern
stuff.
And the 2100S runs RTE-II from the fixed platter of the 7905.

Simh has proved to be very useful especially when generating a new system.

Hi
I have a 2113E myself that is woriking but I have no peripherals. I just got a
HP-IB board for it recently but I'll need something to connect to it. There is
a drive on ebay right now but I'll not be around for the couple weeks
so I'll need to wait for another.
I figure the HP-IB is the easiest option for mass storeage. I'll most likely
need to write a driver but I can do that.

Hi Christian
I don't have a 12821, it is a 59310. It should work for most
any HP-IB thought.
I do have a 13175 board but without the external controller,
it is not much use.

What's wrong with DVM33 (supposed you have a 12821A disc interface card)?

One difference is that the 59310 is about 1/2 as fast: 470 KB/sec with
standard memory and 570 KB/sec with high-performance memory. The 12821 is
buffered, so DCPC can steal every I/O cycle vs. every other I/O cycle for
the 59310. Speed is 937 KB/sec. (Source: HP 1000/9000 Interface Products
Specification Guide, 5954-6312, August 1985.)
I suspect that if an unbuffered drive is used with the 59310, overrun
errors would occur. If they didn't, performance may be terrible, as you
might incur a one-rotation latency for each sector, unless the drive format
was interleaved.
The 12821 was the interface supported for hard drive connections under RTE;
the 59310 was positioned as an instrumentation controller.

Hi Dave
This is good info. I was thinking of using it intially with a GPIB board in my
PC. Speed would be no issue here since it will self throttle.
I was hoping to get it running with one of the newer 9000 series drives.
I hope these are buffered.

New subject: FS: Wirewrap Prototype Boards
Hey guys,
Sorry for the shameful plug but...
While digging through my stash of stuff, I came upon a pile of AUGAT
wirewarp boards. I had totally forgotten that I even had them until I saw
the recent posts about prototyping.
The boards are approximately 10" X 10" square. They have gold pins that are
in a .1" X .4" grid with 31 rows with 82 pins in each row. There are also 21
V+ and GND pins between each of the rows. There are decoupling caps soldered
to about 20 percent of the power supply pins. That's 2400+ empty pins on
each board!
I got the boards many years ago from a scrapper. He had a gaylord bin
completely filled with them. Must have been 1000 boards in that bin! Some of
the boards will have a few bent pins but, they can be easily straitened.
Gold was much cheaper back then so, I grabbed an armload (30 or so).
When I needed a board for a project, I just used a jigsaw and cut them into
smaller pieces appropriate for the project. Doing that, you can get several
nice project boards out of each of the large boards.
The boards were from and existing system so, they are already wrapped. To
use the boards, you'd just have to unwrap the pins. It's tedious work but at
least it is somewhat therapudic.
At this point, I making my own PCB's so, I really don't need the wirewrap
boards anymore. So, before putting them on ebay, I figured I'd offer them
here.
I don't have any pictures but I can take some if anyone is interested.
These are really nice boards so, I think they would be a bargain at $20 each
(plus postage) from North Carolina. Any takers?

Were these for 10K series ECL? (0.3" spacing for DIPs + 1 row for
SIP terminators). Otherwise, I'm having trouble picturing what these
would be used for.
