program, was written by a team of dedicated individuals:

  The JAM.SYS device driver -- designed and written by
      George A Reznik and Igor A Serikov

  The JCREATE, JSIZE, JMOUNT, JDIR, and JMAX utilities --
      George A Reznik

  The JCHKDSK utility -- Alex A Vasilenko

  The JMW utility -- Oleg Muraveynik

  The JCMD utility -- Igor A Serikov and Dmitry S Kohmanyuk
 
  The JPROTECT utility -- Compact Soft group <compact.soft@cs.kiev.ua>

  The JAM documentation was written by George A Reznik

Credits
========

Many excellent ideas, help with testing under DR-and Novell DOS,
and several sections of the JAM User's Guide were provided by
Dmitry Kohmanyuk <Dmitry.Kohmanyuk@UA.Net>.

Thanks to Vadim Vlasov <vvlasov@inucres.msk.su> for providing
fragments of source code of his excellent COMBI-Disk package, and
putting up with many comments concerning DOS & Windows internals.

Valuable feedback on the JAM documentation, and many suggestions
on improvement of the JAM functionality were provided by
Peter Gutmann <pgut1@cs.aukuni.ac.nz>.

Oleg Muraveynik investigated several problems with latest versions of
Windows, W4WG, Chicago and commercial packages for them. He also found
an infamous bug in the JAM 1.0 with large compressed drives (300..512M).

Chris Yearsley <cmy@cs.keele.ac.uk> investigated a very unpleasand system
behaviour working with the JAM 1.18 extendable drives (bug in MS-DOS 5
BPB -> DPB convertor (acceessible also as INT 21h/AH=53h)).

Thanks also to Igor Sviridov <sia@cs.kiev.ua>, Dmitry Kohmanyuk
<dk@cs.kiev.ua> and all the good folks at Communication Systems, Ltd.
for their ideas and support during this project.

Special thanks to the following people, who sent detailed bug reports,
valuable comments, and/or suggestions on previous versions of JAM:
