Was this the film that established that:
1) electrons are blue
2) protons are red
3) neutrons are green

Hoosier politicians have particular trouble understanding
that some things are simply beyond their control; at some
time (during the 1840s IIRC), a Hoosier legislator proposed
a bill to change the value of Pi to 3.0 since that would
make all calcultations involving Pi more easy to perform.
I'm really surprised it that it failed to pass...

The new cables and fittings in mine are a mixture of Cat 5e and Cat 6, but
I'm keeping the proper yellow stuff and the blue drops. I suspect the
microVax would be offended otherwise :-)

Chuck-
WHERE are you able to find carbon tetrachloride? I thought it had
been banned, and I haven't been able to find it for years.
Really need some, too, to deglaze some rubber...

I'd like a detached small building with the following.
1. a raised tile floor,
2. anachoic tile on the walls and ceiling, kind of like egg shell foam which
absorbs noise.
3. 4 plex power boxes under every other tile
4. Non fluorescent lighting
5. air-conditioning through the floor
6. 1 window overlooking the lake
7. Separate shop area
8. Separate storage area with steel shelves accessible from front and back
9. Loading dock area
10. workbench with power strip along entire front edge
11. Small van to haul/pickup stuff
When I was growing up on the farm we had outbuildings for everything.
Chicken coop, granery, tool shed, pump house, shop, garage, dog house, and a
barn. Seemed to keep stuff located somewhat together.

Dreaming not working
mmcfadden(a)cmh.edu
I've gotten interested in the Tektronix 4041 system controllers. Does
anyone have one that they might be willing to sell or will trade for other
vintage computer stuff? I'm especially looking for the detachable keyboard
for the 4041. I'm also intersted in swapping information with anyone about
the 4041. Contact me directly.

Hello -
I pulled 2 IBM 6091 19" monitors out of the trash. I think they were
used on their power pc computers. I need info on this monitor, such
as resolution, refresh rate and what are the white and black bnc
connectors for.
Any help is appreciated.

No, No, No! They fall down the cable quite well, but once they fall
down, they can't get back up!

IIRC the 420 is a 440 without the differential side populated, Here is the
440 manual save in text from their site, If you the original HTML version I
have it also.

CQD440/443 Qbus Controller Installation Guide
The QBUS CONTROLLER is an intelligent high performance Q-Bus
single-ended or
differential (sync/async) SCSI Host Adapter with dual SCSI ports. The
QBUS
CONTROLLER is fully compatible with the DEC Mass Storage Control
Protocol
(MSCP) and Tape Mass Storage Control protocol (TMSCP).
The QBUS CONTROLLER can be used with the LSI-11/23, PDP-11/23+,
Micro-PDP-11/53, 11/73, 11/83, 11/93, MicroVAX II, and MicroVAX III, VAX
4000 and DECsystem 5400 systems. It supports RT-11, TSX, DSM-11, ISM-11,
RSX, RSTS, VMS, UNIX, ULTRIX, and other operating systems which use
DU/TU
drivers.
Models:
CQD-440/TM Disk and Tape (P44010A in U79 and P44009A in U93)
CQD-440/TMP Disk/Tape with Passthru (P44010A in U79 and P44009A in U93)
CQD-440/TMS Disk/Tape with Hardware Shadowing
(P44010A in U79 and P44009A in U93)
CQD-443 has the MicroVAX-3 metal mounting bracket, otherwise is the same
board.
Board Size Quad Wide Q-bus
Emulation MSCP (DU driver) / TMSCP (TU driver)
Bus Interface Standard MicroVAX or LSI-11 Q-bus
Addressing 18- or 22-bit Addressing
Interrupt Priority Level 4 or 5
Interrupt Vector Software programmable
Transfer Mode Normal or block mode DMA
Command Queuing Commands with optimized seek
Data Buffer Capacity Virtual data buffer (infinite size)
Bootstrap Auto bootstrap or utility bootstrap
Defect Management Dynamic defect management
Software Supported All standard DEC operating systems
Multiple-Hosting Support multiple-hosting for disks, optical drives
and tapes.
Formatting On board format and bad block replacement
(ISO standard for optical erasable disk format)
Partitioning 2 or 4 equally divided partitions for disk drives
Shadowing Any two disk drives of equal size on the bus can
form a shadow set (for /TMS version only)
Optional Software Tape Monitor Utility (TMU)
SCSIformat ON-LINE (FMT)
SCSI Library Manager (SLM for /TMJ only)
LED Indicators Self test, error conditions
Peripheral Interface Single Ended SCSI
SCSI Transfer Rate: 10.0-MB/sec in Sync 7.0-MB/sec in Async
SCSI Bus Parity Odd parity
Devices Supported 7 SCSI devices disk or tape
System Performance disconnect/reconnect, multiple-host
SCSI Cable Length Single ended, up to 20-feet (6-meters), Single-ended
fast up to 9 Feet and Differential narrow up to
82 feet
Operating Temperature 5 to 50 degrees C
Relative Humidity 10% to 90% , Non-condensing
Power 5V DC 2.0 A
Selecting CSR Address
Before you install the QBUS SCSI host adapter under the VMS, Ultrix or
Unix
operating system you must select the Control and Status Register (CSR)
address. If /T(tape only), then the appropiate tape csr is required. If
/M(disk only), then the appropiate disk csr must be selected. If the
dual
function /TM controller is enabled so that both disk and tape are
supported,
two CSR addresses are required, one for disk and the other for tape. If
/TM
is being used as a tape only or disk only, then select the single
appropiate
CSR. Click here for help in CSR Address selection.

On-Board Utility
The Utility can be accessed through the system console or the RS-232
Port on the CQD-440 or CQD-443. The CQD-440 uses a 10-pin RS-232
cable.
The CQD-443 uses the same RS-232 MMJ cable used on the MicroVAX-3.
To access the On-Board Utility through the RS-232 port, plug in the
cable and power-on or Restart the computer. The On-Board Utility
will
display on the screen. Be sure to set the terminal to 9600 baud, 8
bit
data, and no parity.
Accessing the Utility Through the LSI or VAX System
The On-Board Utility Program can be accessed by means of an ODT
command
for LSI and VAX systems.
The above information can be changed without notice.
