It doesn't matter ifeither or both drives are real diskdrives, or ramdisks.It also requires a memlow no greaterthan $2000 (decimal 8192). Mostversions of DOS should run thisprogram. q/L 04L5 (Software historyUnzip 1.0 was started and completedin a week. It was written on a PCand assembled using ATASM. It wastested in an emulator, usingSparta Dos 3.3a. and MyDos 4.50. q/L 05L8 (Misc. notesUnzip 1.0 only supports ONE of thecompressions that PKZIP 2.04g,PKZIP 2.50, and WinZip supports.Fortunately, this is the DEFLATEmethod, which is the one they usethe most. q/ (The DEFLATE algorithm requires alotof RAM for it's buffers and tables.The actual code uses less than 4k ofRAM. One buffer uses 32k of RAM.This doesn't leave much room forsupporting more compression methodsand bells and whistles. q/ (Possible future enhancements to theprogram might be the raising thememory requirements. This would beaccomplished by moving either thecode or the buffers to the expandedRAM banks. If this were done, thensupport for the other compressionmethods and other bells and whistlescould easily be included. On thedown-side, such a program would onlyrun on machines with 128k or more ofRAM. Another enhancement I wouldlike to include is support for diskswapping. q/L 06L 0 (Exiting program.l FfffEEE Eۥ)*+,иE%F򥒙`  (08@P`p !1Aa  0@` @ `P0pH(hX8xD$dT4t L,l\<|B"bR2r J*jZ:zF&fV6vN.n^>~A!aQ1q I)iY9yE%eU5u M-m]=}C#cS3s K+k[;{G'gW7wO/o_?
