EPSUTIL.EXE --- EPS disk utilities for the IBM PC
Version 1.40
Michael Chen mchen@groucho.cs.psu.edu
November 2, 1992
This program's features include:
* read/write raw disk images
* read/write EUI format (unused sectors omitted)
* read/write GKH files (the ftp standard...)
* verify disks
* format EPS disks on your PC!
* user-changeable format parameters
(interleave, gap length, sectors per track)
* edit/browse disk at the sector level
* supports formats other than standard (10 sectors per track)!
The interface is pretty obvious, but the command-line options are not (if
only because there need not be any). The main menu line, when the program is
run with no arguments, looks like this:
C)hange format parameters,
G)et EPS disk into EUI file, P)ut EUI file to EPS disk,
^R)ead raw image from EPS disk, ^W)rite raw image to EPS disk,
R)ead EPS disk into GKH file, W)rite GKH file to EPS disk,
V)erify, F)ormat, E)xplore EPS disk, or Q)uit?
The first command-line argument is used as the response to this menu.
Note: C is an invalid command-line option.
The second command-line argument is the drive letter (if applicable).
The last command-line argument is the DOS filename to use (for all the
commands that need a filename: get, put, read and write).
If any of these arguments are missing, and the program needs them, it will
prompt for them.
Note that there are three keys which are not listed as editor commands.
The plus key increments the block number, the minus key decrements it, and
the Enter key reads the current block.
The editor requires EGA/VGA (it uses the 43/50-line text mode so that the
whole sector will fit onscreen), and (obviously) a 3.5" disk drive.
If anyone uses this enough to merit it, and can actually afford to do so,
donations would be appreciated, whatever you think is suitable (how about
sample disks for an unexpanded Classic, if not money...), sent to the

Wish lists, suggestions, bug reports, etc. should be directed to the above
e-mail address.
The source code for this utility is also available. This code may not be
altered without my permission (so I can keep track of revisions), but may be
used freely for non-profit purposes.
The change in this revision is a module to support the GKH format. The
EUI format is still there, but since no one else has utilities which can
read it, I guess I'm going to be the only one to use it.
BTW, the reason for adding the GKH support was because I couldn't download
epswrite and epsread for some reason this morning.

P.S. Coming attractions (I hope):
* EPS file reading and writing (later, support for .EFE format)
* EPS file undelete (once I figure out how!)
