Recently there was an article stating that a copy of a neural network simulator for the Mac called Mactivation (Version 3.2) was on colorado.boulder.edu available for anonymous ftp collection. I just went in and in the /pub directory found a file called mactivation.3.2.sit.hqx.Z, but got suspicious as this file is only 2921 bytes long. I had a look at it, and found that it is actually a DIRECTORY listing of the same account - only the mactivation file in the listing is a couple of hundred K long. Hence, it would appear that someone has managed to overwrite the file with a directory listing. Is there any chance of it being replaced and a message sent to this newsgroup to say when it has happened? Thanks in advance. ---------------------------------------------------------------------- Peter K. Campbell | 2/M6 | Telecom Research Laboratories | Phone : + 613 541 6751 P.O.

Mactivation version 3.3 is available via anonymous ftp on alumni.Colorado.EDU (internet address 128.138.240.32) The file is in /pub and is called mactivation.3.3.sit.hqx (It is stuffited and binhex'ed) To get it, try this: ftp alumni.Colorado.EDU anonymous <any password will do> binary cd /pub get mactivation.3.3.sit.hqx Then get it to your Mac and use Stuffit to uncompress it and BinHex 4.0 to make it back into an application. If you can't make ftp work, or you want a copy with the nice MS Word docs, then send $5 to: Mike Kranzdorf P.O. Box 1379 Nederland, CO 80466-1379 USA For those who don't know about Mactivation, here's the summary: Mactivation is an introductory neural network simulator which runs on all Apple Macintosh computers. A graphical interface provides direct access to units, connections, and patterns. Basic concepts of network operations can be explored, with many low level parameters available for modification. Back-propagation is not supported (coming in 4.0) A user's manual containing an introduction to connectionist networks and program documentation is included. The ftp version includes a plain text file, while the MS Word version available from the author contains nice graphics and footnotes. The program may be freely copied, including for classroom distribution. --mikek internet: mikek@boulder.colorado.edu uucp:{ncar|nbires}!boulder!mikek AppleLink: oblio
