Support of New Greeley Discs
on the L-Series
By Davis FieldslDSD
The recently-announced HP 9134A
Disc from Greeley Division is now a
supporting L-Series peripheral
device.
Please note that since the 9134A
does not have a software input device, a supportable L-Series system
must have some other such device,
such as floppies, minifloppies, or
magnetic tape.
Specifically, this means that the
9134A Disc cannot be used as a
system disc for a Model 5 without
minifloppies (a 2 142B or 2 122B).A
Model 5 with minifloppies,together
with the 9134A Disc, makes a very

attractive combination. All the
necessary instructions for use of the
9134A with the L-Series may be
found in the 9134A User's Manual.
By the way, the HP 9135A
Winchester/minifloppy combination
is incompatible with the L-Series and
we have no plans to support this
combination on the L-Series in the
future.
MIL-STD 1553B Card Now
Available on the HP 1000
By Dave KlinelDSD
You can now offer an M, E, and F
computer plug-in card and driver for
the new military airborne communication bus called "MIL-STD 15538."
The new card is a 93788A and is
available from the DSD specials
group. The cost is $12,000 each,
with minimum initial quantity of six.
(DSD will attempt to combine orders
from more than one customer.) Delivery is approximately 26 weeks.
The 1553B bus is the standard for
airborne avionic communication for
US and some foreign military airplanes, so your military/aerospace
customers worldwide could use this
capability for testing avionics, or for
airborne software preparation.
The MIL-STD 15538 bus is a one
megabitlsecond serial communication protocol developed by the US
Air Force in the late 1970s to standardize interfaces between airborne
avionics such as computers, navigation equipment, and radars. It has
been widely specified by the US Air
Force on new airplanes and its use
has been increasing among other
services and countries. There is a
growing need to use 15538
communication.
DEC reportedly has had a 1553A (an
earlier version) card-set available for
several years from SCl (an OEM), of
Huntsville, AL. A new "B" card-set
from DEC will be available shortly.
The new DEC card-set is expected to
sell for $1 1,000 with discounts to
40% or more, for quantities in the
dozens. Our new MIL-STD 15538
card is slightly more expensive, but is
supported directly by HP.
In discussing 15538 with customers
you need to distinguish between
15538 communication, as performed by the 93788A card, and bus
testing, which our card does not do.
Bus testers can also communicate,
but they are expensive ($9,000 to
$40,000 each), limited (the low
priced ones can only talk to terminals, not controllers or monitors),
and big (nearly a foot of rack height).
Where bus communication is
needed, the 93788A is a good solution. Where bus testing is needed,
the above testers can be interfaced
to the HP 1000 via the HP-IB.
