EXCEL-9: A 6809 Card with FLEX..............Bob Sander-Cederlof

For the last month and a half I have been working with a fantastic new device: the EXCEL-9 from Seikou Electronics in Japan.  The EXCEL-9 contains a 6809E CPU, 8K bytes of ROM, and an interval timer.  The 8K ROM contains a monitor with 35 commands (including mini-assembler anddis-assembler commands).  The introductory price of $399.95 includes the FLEX Operating System from Technical Systems Consultants (TSC), with utilities, text editor, and macro assembler.

The board will soon be appearing in your local computer stores, courtesy of ESD Laboratories.  I worked with them to translate the excellent reference manual into English.  (That explains how I obtained one of the boards so early.)

EXCEL-9 has a lot of unique features that should make it a very popular board:

*  An on-board interval timer (with 24 intervals from 2 microseconds to 16 seconds) can be used from both the 6809 and 6502.

*  Built-in linkage routines for calling 6809 subroutines from Applesoft, Integer BASIC, or 6502 machine language.  You can also call 6502 routines and even DOS 3.3 commands from 6809 programs.

*  Option of using standard Apple intelligent interfaces with 6502 firmware, or of using new cards with 6809 firmware.

*  Memory Mapping that supports the FLEX operating system.  Future option to add external memory to EXCEL-9, allowing full-speed multiprocessing.

I intend to handle these boards.  You can order them from me now, but please allow a while for delivery.  The documentation is ready for the printer, but not yet printed.
