Dear Atari User:

         I'd like to tell you about SIO2PC, a hardware/software
         system which links your 8 bit Atari and any PC compatible
         computer.  Essentially, it lets your PC emulate up to four
         Atari disk drives plus provides other features.  I have been
         improving the system for over seven years and have been
         gratified by feedback from a small but enthusiastic group of
         users.

         FEATURES:

         Store your Atari programs and files on your PC's hard and
         floppy disks. Create 1 to 4 ramdisks in your PC's ram space,
         or alternately, use direct file access for disk images
         larger than ram. Disks can be any size up to 16 MB, single
         or double density, designated D1 to D8.  You can boot from
         the PC, so after transferring your files you won't even need
         an Atari drive again.  Works on any PC from an original 4.77
         MHz 8088 to a '486 or Pentium.  The PC must have a serial
         port.

         The system emulates an Atari drive at the hardware level, so
         any DOS will work. CIO, SIO, even direct hardware calls will
         work.  It's inherently faster than a real Atari drive and
         additionally supports high speed I/O with most versions of
         SPARTADOS.  No direct sector writes are used on the PC.
         SIO2PC won't hurt your hard drive or data.

         You can transfer your Atari files to PC files and vice
         versa.  Your Atari can have direct access to PC files which
         haven't even been converted to Atari disk images.

         The PRINT-THRU function lets you print from the Atari,
         intercept the output on the PC, and send it to your PC's
         screen, PC file, or printer, with or without translation.

         Many enhancements, such as DOS shell, extract Atari
         directory, etc. have been added over the years. A status
         line tells you what is  happening on the serial bus.  I'm
         currently working on enhancements to allow the PC to
         interact directly with an Atari drive, and to emulate bad
         sector disks.  Still, the program is compact (less than
         40KB) and fast due to being coded entirely in assembly
         language.

         How can you get one?  I'll build you one or send you a kit
         of parts.  Or you can build your own.  Many people want the
         interface to transfer files for Darek Mihocka's Xformer and
         are surprised that it costs more than Xformer did.  Please
         be aware that the hardware device consists of about 15
         components and takes over an hour to assemble, test,
         package, and label.  Since I only do a couple or so per
         month, I can't realize any economy of scale in assembly.
         And I've put in thousands of hours programming time on the



         software.   Anyway, I have recently cut my prices from
         $55/$35 to $40/$30 postpaid.  So: $40 wired; $30 kit; or $10
         for just software and building instructions.  The interface
         is about 4 feet long, connector to connector.  I can also
         supply a 6' standard serial extension for $5.  Of course, I
         always include all the latest software if you get an
         interface or disk from me.  NOTE: This is a hobby for me,
         not a money making project. I have never advertised it, but
         word-of-mouth response has been good. You must accept
         responsibility for construction and/or use of the system.

         I hope you decide to try it.  I think you'll be pleased if
         you do.
