IIRC I used to have a 1968 DEC Handbook that showed it. I can't remember
what I did with the book.

For those who care, work is progressing nicely on the Internet
re-implementation of the Commodore(tm) QuantumLink service. The hope is
to re-introduce the basic service on the 20th Anniversary of the Q-Link
introduction: November 1, 2005. There is still plenty to implement, and
information to load, but the infrastructure looks to be in place. We've
secured the quantum-link.org domain for information and the eventual web
portal.
As of this week, the service has been set up for continuous operation,
with new code drops loaded in the early mornings. the server can be
accessed at qlink.quantum-link.org:5190 by a real Commodore C64/128
using an RS232 interface cabled to the Internet via PC or
RS232-to-Ethernet adapter. The server can also be accessed via the VICE
and WinVICE C64 emulator. Details for both configurations are posted on
the www.quantum-link.org home page.
As of 8-30-2005, People Connection and all main information areas are
functional, as is email, online messages, and message bases. File
transfers will be implemented soon, and then the basic People Connection
games. Re-implementing Club Caribe and the Habitat system are also
goals of the project, though more ambitious and will not be attempted
before the launch.
Although the server is still in pre-alpha stage, it regularly hosts a
lively chat in the PC Lobby with a dozen or so users. I encourage you to
join us for some fun alpha and beta testing.
The system will be demonstrated and a discussion on the methods for
re-implementing this complex service given at the SWRAP EXPO in Chicago,
IL on September 17th, 2005.
Although many folks have given support to the project, a few deserve
special mention. I want to thank the following individuals:
Keith Henrickson, who spent countless hours with the Q-Link client
runnng in the VICE monitor deciphering and reverse engineering large
portions of the Q-Link command structure and verb set. Keith has also
continued to oncover new portions of the verb set, including message
bases and file transfers
Keith Elkin, whose archived videotaped Q-Link sessions proved
instrumental in setting message layouts, response strings, and timing.
Raymond Day, who managed to archive a trace of 2 actual Q-Link user
sessions. One provided the key to fully implementing the information
areas, and allowed the extraction of 200+ menu items and 100+ files from
the original system, and the other held information crucial to
implementing message bases and provided insights on how the file areas
operated.
The VICE Emulator team. Without this tool, development would not have
progressed to this state.

Fellow techies,
I was at Boeing Surplus today in Kent, and I spotted a nice 9-track drive in one of the 'washing machine' style floor cabinets. It was tagged at $25.00.
No idea what vintage or density (I was timestressed), but the I/O cable looked like a high-density D-sub-50 (form factor of a D-sub-37, but with 50 contacts spread across three rows).
I'll bet it'll still be there tomorrow. Bring at least a pickup truck and two strong bodies if you want it.
Keep the peace(es).

Hi
I see no reason one couldn't connect it to just about any machine.
Not an original configuration but still, a working setup. One
might even recover data from original tapes this way.

Hi, Still doing some shop cleaning.
IBM S/36 Model 5362 . looks complete , less Terminal.
This is a desk side system. looks to be in good condition.
Has not been tested or turned on. Has a 8" floppy and
hard drive. There are 2 manuals inside the case.
This is quit heavy. local pick only. 75.00
Also, last call on these. They are on "Death Row"
Grahman magnetics (Carlisle) "Inspector IV MPC"
Mag tape Evaluation system.
This is a Vacuum column Mag tape tester. has lots of LED's
and LED read outs . Quit a piece to watch run. Works.
This is quit heavy. local pickup only. Free to a good home
4) DEC HSC systems. models 60 to 90. no hard drives
These are quit heavy. local pick up only Free to a good home
I'm located in Kent Wa. south of Seattle
Thanks, Jerry

When was this? Do you still have them?

Someone emailed me (a non-collector) with a list of DEC boards and they want
to know if they have any monetary value. I'm not up on many dec boards,
particularly XNNN type numbers. So I was hoping people here could tell me if
any of the below are particularly sought after. I suspect the guy will want
to part with them, likely all at once rather than piecemeal. Let me know!

The question about the ttl oscillator jogged my memory.
Anyone recognize a line of "delay line" chips with names like TD25,
TD50, TD100, etc... The look they were expensive at the time, like $10
around 1976.
The TD100 pinout looks like this:
+------+
input | 1 14 | vcc
| 2 13 |
| 3 12 | 20ns
40ns | 4 11 |
| 5 10 | 60s
80ns | 6 9 |
gnd | 7 8 | 100ns
+------+
I don't have an exact part number or mfg. (I know where I can find one
but it's not easy and will take some work)
I want to model these in verilog but I'm not exactly sure how they work.
They are delay lines, but I'm not sure how they react. The input seems
to be a short pulse from high to low of about 40ns. I'm assuming this
produces an approx 40ns pulse after the prescibed delay, but I'm not
entirely sure.
I would love to see a few pages from a data book which describes how
these react (enough to model them correctly).
any pointers?

Hi Sellam
Maybe one of those industrial steam irons used at the
commercial laundries. I was thinking that you were
dealing with them one at a time. For bulk, you might look
into how the banks iron bills. They have some method
that means they have some kind of machine to handle
the problem. These machine must be making it to scrap
dealers.
