╫HAT'S THE BEST BACKUP PROGRAM FOR ═╙─ DRIVES? ╞ROM YOUR LETTERS, ═╙─ ╙HURECOPY FROM ═EGASOFT AND ╞AST ╚ACK'EM FROM ┬ASEMENT ┬OYS ╙OFTWARE ARE THE TWO MOST POPULAR FOR THE ╙─-2. ╙EVERAL OTHERS ARE SUPPLIED IN ═╙─ COMPATIBLE VERSIONS INCLUDING ═R ╬IBBLE, ─ITTO, AND ╙UPERCLONE. ╙HURECOPY WILL BACKUP MOST IF NOT ALL ═╙─ COMPATIBLE SOFTWARE (AND SOME INCOMPATIBLE SOFTWARE). ╙HURECOPY IS NOT ╤UICKSILVER COMPATIBLE, AND USERS REPORT SOME LOAD DIFFICULTIES AND SOME BUGS. ╔T IS COMPATIBLE WITH ┬USCARD ╔╔.
╙O FAR NO HIGH SPEED BACKUP PROGRAMS FOR THE ╙─-1 HAVE BEEN REPORTED. ╬EITHER OF THE ABOVE TWO ARE ╙─-1 COMPATIBLE. ╞AST ╚ACK 'EM IS SAID TO BE DEVELOPING AN ╙─-1 COMPATIBLE VERSION.

╝╔NCOMPATIBLE ╙OFTWARE╛
╙OME HAVE REPORTED BASIC PROGRAM DISKS THAT ARE ═╙─ INCOMPATIBLE. ┴LMOST ALL UNPROTECTED BASIC PROGRAMS ARE COMPATIBLE UNLESS THEY MODIFY ─╧╙. ╘HE PROBLEM PROBABLY IS DISKS WRITTEN ON AN OUT OF ALIGNMENT 1541. ═╙─ DRIVES HAVE A NARROWER READING RANGE THAN 1541'S. ╘HE BEST SOLUTION IS TO COPY THE OUT OF ALIGNMENT DISK ON A PROPERLY ALIGNED 1541 PREFERABLY TO AN ═╙─ DRIVE. ─O NOT USE A HIGHLY SOPHISTICATED BACKUP PROGRAM, WHICH MAY DUPLICATE THE MISALIGNMENT.
╔N ╔SSUE 1 BACKUP CARTRIDGES WERE MENTIONED AS ONE METHOD TO CONVERT INCOMPATIBLE SOFTWARE TO RUN ON AN ═╙─. ╙EVERAL REPORT CARTRIDGES THAT RUN ON AN ═╙─, BUT FEW ARE REPORTED TO MAKE INCOMPATIBLE SOFTWARE COMPATIBLE. ╧NE USER HAS REPORTED EXCELLENT SUCCESS WITH ╔SEPIC RUN ON A 1541. ╫HEN THE PROGRAM IS RELATIVELY SHORT AS WITH A GAME PROGRAM, ╔SEPIC IS OFTEN EFFECTIVE AND THE PRODUCT IS ═╙─ COMPATIBLE.
╝┼XCHANGE ─ISK╛
╘HE ┼XCHANGE ─ISK IS AVAILABLE FREE TO THOSE WHO SEND IN A BLANK DISK WITH RETURN POSTAGE. ╨OSTAGE FOR A DISK IS TYPICALLY $0.56 ($0.58 ╒╙ TO ├ANADA). ╫HEN SUBMITTING A DISK, PLEASE PUT YOUR NAME ON YOUR DISK, INCLUDE A RETURN MAILING LABEL, AND INDICATE WHETHER YOU WANT ╙UPERBASE FILES. ┴LSO INDICATE IF YOU ARE SUBMITTING PROGRAMS TO ╘HE ┼XCHANGE. ┘OUR DISKS ARE RETURNED COPIED ON BOTH SIDES. ╙IDE ONE CONTAINS THE DATABASE FILES; SIDE TWO CONTAINS PROGRAM FILES. ┼ACH SIDE INCLUDES A "╠╔╙╘ ═┼" PROGRAM CONTAINING BRIEF INSTRUCTIONS.
╘HE MOST COMMON DISK MAILER IS A REUSED ├OMPUTE'S ╟AZETTE MAILER. ╘HE SIMPLEST IS A 6 ╪ 9 ENVELOPE WITH THE DISK HELD BETWEEN TWO PIECES OF CORROGATED BOXBOARD.
╘HE ┼XCHANGE ─ISK CONTENT CHANGES FREQUENTLY. ╙UPERBASE FILES CONTINUE TO BE MOST UP-TO-DATE. ╙UPERBASE IS A HIGH PERFORMANCE DATABASE PROGRAM FROM ╨RECISION ╙OFTWARE SOLD BY MAIL ORDER HOUSES FOR ABOUT $50. ╔T IS USUALLY REGARDED AS A CLASSIC. ┬ECAUSE MANY DO NOT HAVE ╙UPERBASE, ╘HE ┼XCHANGE DATABASE FILES NOW ARE SUPPLIED AS SEQUENTIAL FILES SUITABLE FOR READING IN A WORD PROCESSOR (EXCEPT WHEN ╙UPERBASE FILES ARE REQUESTED).
╘HE ┼XCHANGE ─ISK ─ATABASE FILES INCLUDE THE FOLLOWING--
1. ╙OFTWARE COMPATIBILITY. ╘HE FILE NOW INCLUDES 250 TITLES WITH PARTIAL INFORMATION ON MOST PROGRAMS. ┴DDITIONAL ENTRIES ARE BEING SOUGHT.
2. ═EMBERS. ┴ LIST OF MEMBERS TO ENCOURAGE INTERACTIONS BETWEEN USERS AS IS COMMON IN MOST LOCAL USER GROUPS.

╒SERS REPORT PARTIALLY COMPATIBLE DISK SPEED CARTRIDGES SUCH AS ═ACH 5, THAT ERASE THE DISK DIRECTORY IF NOT WRITE PROTECTED.
╘HE MOST FREQUENT SOFTWARE COMPATIBILITY QUESTION IS ╟┼╧╙. ╔T IS NOT ═╙─ COMPATIBLE. ╘HE MOST OFTEN LISTED IS ╨RINT ╙HOP. ╘HE ORIGINAL IS COMPATIBLE; ╨RINT ╙HOP ├OMPANION IS NOT. ╫HEN MODIFIED BY ├OMPANION, ╨RINT ╙HOP BECOMES INCOMPATIBLE. ═USIC ╙HOP, ALSO FROM ┬RUDERBOND, IS INCOMPATIBLE.
╙INCE ─╧╙ IS VERY SIMILAR, THE SAVE WITH REPLACE BUG SHOULD BE PRESENT ON ═╙─ DRIVES, BUT HAS NOT BEEN REPORTED.
╧N ╔┼┼┼ INTERFACES, ┬USCARD ╔╔ IS MOST POPULAR AND HAS THE HIGHEST SOFTWARE COMPATIBILITY; ╤UICKSILVER IS FASTEST AND HAS VERY HIGH SOFTWARE COMPATIBILITY; ═╙─'S ╔┼┼┼ INTERFACE HAS VERY POOR SOFTWARE COMPATIBILITY AND IS NOT RECOMMENDED.
