Re: Third Party Accessories--HP-41 Message #4 Posted by Tony Duell (UK) on 3 Oct 2001, 6:31 p.m., in response to message #1 by Joe Moran
Christoph Klug describes a number of commerical HP41-compatible measuring instruments in his book 'HP41 Input/Output Board'.
Here's a brief list of them : HP3468 Digital Multimeter (HPIL interfaced); HP3421 Data Logger (Also with HPIL Interface); CMT-200 Data logger (Corvalis Micor Technology, this unit has 1 8 bit input port, one 8 bit output port, 2 handshake lines, plugs directly into the HP41);
CMT-300 Digital Multimeter (also Corvalis Micro Technology, AC/DV volts, AC/DC milliamps, Ohms, again plugs directly into the HP41); Interloop I/O board (32 digital output lines, 16 digital input lines, DIP switch, 8* 8bit analogue input channels, counters, HPIL interface); Interloop Stepper Motor Driver (Drives 4 stepper motors, HPIL interface); Roland Walcher Elektronik Mikro-Logger W41 (13 bit ADC, 8 analogue inputs, 12 bit DAC, 8 bit input, 4 bit output + 4 relays. Also takes option cards for special applications, HPIL interface);
Roland Walcher Elektronik Logger W51B (Similar to the W41, from what I can see, HPIL Interface); and a couple of very specialised units that are not going to be of general interest.
My guess is that the unit you are thinking of is the CMT-300.
