Bill makes a very good point here, in that it is *highly* inappropriate to have shipped out such a huge posting without letting anybody know what it is. On the matter of PKARC, I was able to successfully deal with the .arc file on my UNIX system using a version of arc that identifies itself as: arc - Archive Utility, 5.12. I've had it for at least half a year. Now, as to what PSPICE is: I don't know. I read through the README.1ST and README.DOC files and the only things I can say are: The input is almost identical to UC Berkeley Spice (whatever that is). It appears to have something to do with modeling or simulation of either electrical components or electrical cirquits. The demo version allows a cirquit with only 10 transistors. Frankly, I think that that's pretty pathetic. To ship something so huge around the net, cause people to strip headers off all 14 parts, concatenate them together and pipe through uudecode, then extract the documentation, only to find that *there is no documentation* is obscene. Here's the info on what kind of system is required, so people without don't have to bother. (and other selected portions from README.DOC) I'm glad I took a look, because I don't have an 8087, so can't run PROBE or PARTS, anyway. ----- 2.0) System Configuration Demo PSPICE will run on an IBM PC, XT, or AT with 512kbytes of memory. The floating-point processor (8087 or 80287) is optional. If present the program will run at full speed. Otherwise it will run 5-15 times slower. Either the monochrome or color display may be used. Any printer may be used. [Note, PROBE requires the math co-processor. -rwh] PSPICE runs under MSDOS 2.0+ and requires the system to have been booted with a CONFIG.SYS file which contains the statement: FILES=10 It is also recommended that the CONFIG.SYS file contain the statement: BUFFERS=10 Such a CONFIG.SYS file is included on Diskette 1. For PROBE and PARTS the only difference is that the floating-point processor is not optional. It is required. 4.0) Format of the Input and Output Files The input and output files are ordinary text files and follow the same rules as those for the UC Berkeley Spice program, version 2G.6, with these omissions: 1) There is no distortion (.DISTO) analysis. We recommend using the .TRAN and .FOUR to calculate harmonic distortion. This method correctly accounts for clipping, which .DISTO does not. 2) There is no .ALTER command. In addition, numerous enhancements to the Berkeley Spice have been added including GaAs MESFET devices, group delay, and the ability to reference device libraries in other files. For more details on these and other PSPICE enhancements, the PSpice User's Guide may be purchased separately from the PSPICE program. 5.0) Restrictions for the demo version This demo version of PSpice will run in 512kbytes. It will run with or without the floating-point co-processor. All the features of the production PSpice as of May 1986 are included except that the circuit size is restricted to a maximum of about 10 transistors. Note that for schools teaching introductory electronics courses, 10 transistors may be all that is needed. The production version of PSpice comes with a library of models for about 100 standard devices (diodes, bipolar transistors such as the 2N2222, power MOSFET's, opamps, and comparators). The demo version includes a reduced version of this library with about 10 parts. The library is in the files with extension ".LIB" on Diskette 3. These are ascii, text files and we recommend that you print them out for more information on them.

Note: this demo version of Probe is for IBM and IBM-compatible PC's only. It will not run on the Texas Instruments professional. This demo version of Probe requires the 8087 floating-point co-processor. Unlike the demo PSpice it will not run without it. This demo Probe has all the capabilities of the production Probe as of May 1986. -- Ron Heiby, heiby@mcdchg.UUCP Moderator: comp.newprod & comp.unix "I believe in the Tooth Fairy."
