The programs you want are in the directory MICRO:. Dave Towson info-cpm-request@brl-vgr ---------------------------------------------------------------------------- There is a collossal amount of free public domain CP/M software in three archives on SIMTEL20, a PDP-20 running TOPS-20 at White Sands Missile Range. To get directory listings, crank up FTP with user-name ANONYMOUS and password FTP (or any non-null string) and then do the following: get "micro:cpm.crclst" local_file_name get "micro:cpmug.crclst" local_file_name get "micro:sigm.crclst" local_file_name bye The first will get you a directory of the cpm archive that was moved from mit-mc. This is the one to watch for the very latest offerings as it is updated frequently. The second is the full offering of the CP/M Users Group. It (and the third archive) will be updated as new disks are issued. The third is the full offering of the Special Interest Group for Microcomputers, a service of the Amateur Computer Group of New Jersey. There are many overlaps in the three archives, but you will find the lastest versions in the archive. In general, the archived software is very good, having been worked-over and refined by multiple users. The comments tend to be complete and imformative. Examples of typical file retrievals follow: get "micro: autox.asm" autox.asm get "micro:assign.asm" assign.asm get "micro:ad.com" ad.com All files in the CPMUG and SIGM archives have been stored in a binary format that had its roots at mit-mc. To retrieve any of these files you must use FTP in TENEX mode. If your FTP server doesn't do TENEX use type L8 (which does the same thing). You will have to discard the first four bytes from every program you obtain from either of these archives. This is because the binary format used for storage has the identifier DSK8 in sixbit code at the beginning of each file. To strip the first four bytes, you can use either your host's utilities or a CP/M program called ITSCVT.HEX, which can be found in directory . Files in the archive are stored in two formats, ASCII for DOC, HEX and ASM files, and ITS binary (as described above) for COM and "squeezed" files. Squeezed files have been compressed using the programs available in directory to obtain approximately a 35-percent size reduction. These files, which can be identified by the letter Q in the filetype field (for example, the file micro:z2con.wq is a squeezed file) must be transferred as binary files and then unsqueezed. The unsqueezing can be done on the CP/M system using USQ-20.COM (or whatever is the current version) from directory , or there are several host-based unsqueezers in the archive (see for example, directory ). One last comment: In all of the above examples the quote-characters are there for the benefit of UNIX users. Other operating systems may not need (or may have trouble with) these quotes. Happy hacking! Dave Towson info-cpm-request@brl-vgr
