The H.P. 200LX contains 3 megs. of built-in programs on ROM including LOTUS 123, Quicken, Memo, Appointment organizer, Scientific-Financial calculator, World time, Note taker, LapLink, etc. You can run any of these built-in programs and simultaneously collect radiation data with geiger click, alarm, pop-up control panel-mini graph, etc. by way of the Aware TSR program. Launch Aware programs AW-GRAPH and/or AW-SRAD from an LX Icon to observe auto-updated radiation graph using data stored from Aware's TSR program, jump back to LX system manager to launch another program or jump to another launched built-in program all while the Aware TSR program continues in the background. If you jump back into the AW-GRAPH or AW-SRAD program the graph will automatically update.
The Aware RM monitor draws all necessary power from the H.P.'s serial port. The two AA batteries within the H.P. should continuously power the computer and monitor for several days. The H.P. is equipped with a built in re-charger for use if the two AA alkaline batteries are replaced with two ni-cads.
Carry the H.P. and RM in your pocket and the alarm will sound if you enter a radiation area. The speaker in the H.P. is very adequate. Pop open and observe graph. Meanwhile precise dose rate with date and time is stored to the ram disk. The standard internal ram disk has enough room for over two hundred days of continuous data. Pop in a XIRCOM LAN PCMCIA card and connect the LX to a standard network. Many other possibilities exist with this exciting, excellent, tiny computer.
It took me a while to figure this out, maybe you would want to put it on your website for others.

About our older LCD-60: LCD-60 display module (right hand unit above) with 2 - 6 digit LCD readouts (total counts & counts/sec or counts/min), piezo clicker, LED flash, 3.5mm (1/8") jack with earphone, for using RM-60 (or 70/80) without a P.C. Uses 9V battery. RM cable plugs into the LCD-60's modular jack. RM with P.C. produces much more useful information but LCD-60/RM combo is nice when a portable P.C. is not accessible. 4.4" x 2.44" x 1.06" ABS case. 4.1 mhz crystal. Maximum reading: 999,999 each display.
Normally the RM-60 (or 70/80) is plugged into the serial port of a P.C. by way of snap-in telephone wire. Alternatively you can plug the RM unit into the LCD-60 with the 7 foot telephone cable included with the RM unit. As with the RM to PC connection one can extended the cable to the LCD-60 with telephone extension cord up to 1000 feet.
The LCD-60 has two six digit readouts. One readout shows counts per minute or counts per second and the other readout displays total counts. This is very convenient to easily determine very low levels of radiation while still getting a count per minute or count per second reading.
It is often useful to have the ability to separate the readout from the sensor unit with the snap in telephone wire. For example lets say you wanted to check for radiation from several packages of food. Place the RM-60 in the middle of the pile of packages with the LCD-60 readout at hand. Dangle the RM-60 down a well hole or in a crawl space or by a spring or in a shopping bag of food or surrounded by several bags of vegetables or down by the water tank or next to the air filter unit within the air handler or down a crevice etc., with the LCD-60 readout at hand. The LCD-60's 9 volt battery should last for about 1000 hours of operation.
Both the RM-60 and LCD-60 are palm sized (about the size of a bar of soap). You could connect the two together will velcro strip to form one unit which you can then easily separate and snap in a longer wire. Both units are very rugged.
With the RM-60 you will have everything necessary to run it on a PC as well.
Letter to customer about LCD-60 and personal alarm: The LCD-60 does not include an alarm but it does include two audio outputs. These can readily inform user of an unusual radiation condition. One audio output is the built in piezo clicker. This generates one "Geiger" click per detection. The other audio output is a loud short duration click in an earphone (supplied) or small speaker.
The LCD-60 is highly reliable. It contains two individual counters so user can easily check proper operation, but the circuit is not excessively complex. Over the years we have found the less complex the circuit the higher the reliability. This applies to the RM units as well which contain rugged silicon semiconductors with majority of the complexity residing in the PC + software (or LCD-60).
Under normal background conditions one hears approx. 10 clicks per minute (with the RM-60, our least sensitive model) by way of the LCD-60's earphone or piezo clicker. 5 micro Sieverts per. hr. (500 micro Roentgen per hr.) is a common level used by various organizations when stating permissible continuous exposure levels. This would generate approx. 500 clicks per minute. Such a change in activity will readily alert user to check LCD display revealing the Counts per Second reading. Simultaneously the LCD-60 is tallying total counts and displays this in a second 6 digit LCD display.
As you increase radiation levels eventually the piezo clicker emits a continuous loud tone. On the other hand since the duration of the click in the earphone is very short (the same as the dead time of the tube), with higher radiation levels the earphone generates a hissing-crackling tone.
The point is a user can stay alert to the radiation condition very easily by ear and readily detect "hot areas" and how activity changes with location just with the earphone (and/or piezo clicker), and check the two six digit readouts anytime.
Since the LCD-60 costs $189 we also sell the $19 "Clicker" which is a tiny circuit that includes a small run of telephone wire to plug into the RM unit, a 9 volt battery clip and an earphone jack with earphone. (By the way one can plug a "Walkman" style headphone in either the "Clicker" or LCD-60 earphone jack or a small speaker). With the "Clicker" one can keep abreast of the situation as above but the clicker does not have the readouts. (An RM unit with "Clicker" makes a good low cost prospecting tool. Find Uranium deposits, Radon vents, etc.)
One step beyond the LCD-60 includes the use of Hewlett Packard's 200LX, 100LX or 1000CX (The 1000CX is just like the 200LX minus all the built in programs save the communications program and Lap-Link). Also there are many "holster" style straps to hold the PC and RM to the body as well as a great many additional accessories available for any of the HP LX-CX series of palmtops.
Once you load the Aware software onto the LX-CX's CMOS ram disk (including AW-GRAPH if so desired) all features of the software are available including the Alarm feature. At any time the user can glance at the display and look at the real-time graph showing the entire session's radiation level. One can also hear the Geiger click and alarm siren emitted from the LX-CX speaker. Meanwhile the entire session is stored to a disk file for later review if so desired.
All software can be loaded from the LX-CX autoexec.bat file so all the user need do is turn the LX-CX on and when done turn it off. To start a new radiation storage file on the LX-CX all one need do is re-boot the LX-CX. With autoexec.bat statements one can copy a previous rad file to another sub-dir before the program is launched.
So the RM with LX or CX is the ultimate personal alarm system but the RM with clicker is cheapest.
