Project Box Bonanza!!
RF-Tight Steel Enclosure |

Need a solid steel anodized, RF-tight project box? This is
the one!! It has just 4 holes in the front panel for included LEDs and 2 holes in
the back panel
for an "F" connector and a 5 pin
"DIN" connector. When manufactured, they even left bare metal around the
holes for the cover mounting screws to insure good metal to metal contact. The plastic
front
panel
mounts to the steel front panel and is removable with the 3 green LED positions marked
for Power, Cable, Link and a red LED marked Message.
The steel box is 18-1/2" wide x 10" deep x 3-1/2" high and includes
an internal divider spot welded in place creating a 4" wide compartment for the
included power supply. The power transformer puts out 8.5 vac @ 0.5 amps and 22 vac
@ 0.5 amps. Mounted on the back panel are a 5 volt, 1.5 amp regulator and a 1.5 amp,
18 volt regulator on a small heatsink.
Filter capacitors are 22,000mF at 16 volts and
470mF at
50 volts.
The end result is a linear DC +5 volts @ 1.0 amps and +18 volts @ 1.0 amps supply
that can supply power for many different projects. A 1/2 amp slo-blow fuse and holder
are
included
as well
as the SJT 18/3 power cord.
Each cabinet also includes a 'Logic Board' and an 'RF Module'. See the description
below of what this was for. There is a 40" long cable with 5 pin male "DIN" connnectors
on each end. Also included is a 40" RG-59 cable with male "F" connectors
on each end. A great project box with some usable parts for a bargain price. Shipping
weight = 16 lbs.
Own a Piece of History
The NABU Network was the City of Ottawa
Canada's step into the future well before its time. Please read the historical perspective
on this very
early bi-directional home/business access network.
We were able to acquire the set-top converter / controllers
for this network. This equipment provided the interface between the 117 MHz cable
signals that were exchanged
between
the DEC server and the user's TV. There was probably a keyboard type device used
with this for selecting services and interaction.
In addition to the power supply described above there are 2 modules inside the unit.
There is an RF module that down-converted signals from the cable connection and up-converted
requests to be sent to the server. This also provided the TV signal to the user's
set. All sections of this unit are enclosed in another RF-tight box. There are 4
circuit
boards for frequency synthesis, data in and out and RF conversion and dual helical
coil bandpass filters. All parts on these boards are descrete components and include
some LS and CMOS chips. This module is mounted on a 4 3/8" x 8 1/2" one-quarter
inch thick heatsink.
The logic module includes 4 socketed chips: a TR1865CL-04, a full duplex UART, a
SC87253P 8 bit microprocessor, a N8X60N FIFO I/O controller and a pre-programmed
ROM. The remainder
of the parts on this board are numerous 74LS series logic ICs.
While there are a lot of components included on these boards they are literally antique
and more of a curiousity than anything else. Keep in mind that at the time these
boxes were made, there was no internet. Only BBSs and teletext services.
By the way, if you are familiar with the service these boxes were used for, let us
know so we can share the information with others.
I just received the NABU steel enclosure and what a great project box it is. I will use it to install a 500 watt
Stereo amplifier, a special switching power supply and an equalizer. Thank you for a great find.
