geoBEAP is Born!

"geoBEAP" stands for Bo's Excellent Archive Program, and was born from a need to convert .D64 emulator images onto regular 1541 disks. Unhappy with the default speed of my Commodore drives, I turned to GEOS, hoping to take advantage of its turbo routines. At the same time, I was taking a course in college in which we were studying data compression. With all this going for me, I sat down in front of the Commodore SX-64 I kept at work and wrote the original geoBEAP 1.0. This version and the follow-up, geoBEAP 1.5, were sold to LoadStar.

So, how did this new version come to be?

Over the years, I entertained the notion of writing a companion to geoBEAP (called geoBEFAP) that would have included a few file archive formats, including one that would use the .BEP compression algorithm. I also thought about rewriting geoBEAP 1.5 to take advantage of my geoModules project. Eventually, some idle time in the Summer of 2001 gave me an opportunity to do both at once!

geoBeap 2.0

The new geoBEAP 2.0, unlike the old, is a VLIR application based entirely on the geoModules foundation. In fact, two new modules were born during its writing: a module for doing the GEOS Convert function, and another for copying any and all file types (including GEOS, VLIR, and relative files!). Its interface resembles the old to an extent, but was actually based off the code from The Major ReOrg.

So, what does the new version do?

Lots! geoBEAP 2.0 will create (pack) and dissolve (or unpack) the following disk images: .D64 (standard C= emulator 1541 disks), .D71 (standard C= emulator 1571 disks), .D81 (standard C= emulator 1581 disks), ZipCode 4-packs (by DarkStar, the original disk image archiver), EMUTIL single compressed images (supports ANY drive type, and gets better compression than .D64 or ZipCode), EMUTIL multi-file compressed images (same as above, but multiple files), and the original .BEP format (unchanged since 1.5). geoBEAP 2.0 ALSO supports the following FILE archive formats: GEOS Convert (.cvt) files, LYNX (.lnx) archives (includes relative file support, and support for EVERY version of LYNX I know of), and ARK (.ark) archives (including relative file support). The LYNX support also includes geoPack files, making geoBEAP a direct replacement for that aging application.

geoBEAP 2.0 is being released as shareware!

There is a lot of great plans I have in the future for geoBEAP, and it was only exhaustion staring at the same kind of code every day that made me want to just STOP. I was poised to add .T64 (C= emulator tape image) format, as well as .LBR (library 64 and library 128) formats. During my research, I also discovered that Wraptor V3 uses LZW. This gives great hope that perhaps it may be added at some point also, since I am familiar with that algorithm and may be able to reverse engineer it. A lot depends on how much interest is expressed in this program however, so register it soon!

Revision Notes:

1/30/98 geoBEAP has been updated to version 1.5! It now supports CMD Native mode direcories for creating and unpacking .BEP format archives. Wheels support has also been added. Lastly, geoBEAP will now run under GEOS 128 in both 40 and 80 columns. Ask for issue #145!

8/11/01 geoBEAP has been rewritten! In addition to D64s and .BEP archives, geoBEAP now supports Convert (.cvt) files, .D71 files, .D81 files, EMUTIL Single Compressed disk images, EMUTIL multi-file Compressed disk images, ZipCode 4-packs, LYNX (all versions) file archives, and ARK file archives.

2/12/02 geoBEAP 2.0a released with a few minor bug fixes in the RLE format code.
