New S-100 Boards

This section of this web site is a detailed to many new S-100 boards I and others have recently constructed.  Still utilizing the basic IEEE-696 S100 bus format, we are incorporating modern designs into these new boards.  The long term goal being to adapt most major microprocessor chips (and support IC''s) to the S-100 bus.   We intend for example to have S-100 boards with master and slave CPU's like the 8086, 80286,80386, 80486 & Pentium  family, the 68000 Motorola family, all the way up to more recent CPU's like the Propeller and RISC/ARM chips.  This has been, and will continue to be, a multiyear project.  A core of enthusiastic people have got together to do this. As you read more please consider joining.  The growing list of new S-100 bare boards are listed here.  If you are interested in obtaining a board please contact me (see bottom of the home page), or Andrew Lynch at N8VEM. For those interested, the finished boards are typically available at cost (~$20 - $30 each, depending on demand). Remember this is a true hobby/non profit operation!  Support is limited.

By way of showing the evolution of these boards, I will describe my own S-100 IEEE-969 system.  This is a completely "homebrew system". Originally built in the early 1980's utilizing many of the S100 boards of that era.  As I add new S-100 boards, I will go into some detail in an effort to help others build similar systems or allow them revive S-100 systems they may have stored away or have recently acquired. 

While none of this is rocket science, it does require some degree of electronic knowledge, familiarity with the S-100 bus and for the software, a working knowledge of CP/M, CP/M86 and MS-DOS (Programs, BIOS & Drivers) .  If you wish to become more informed about the S-100 bus itself try and get your hands of the book "Interfacing to the S-100/IEEE696 microprocessors" by Sol Libs & Mark Garetz.  This book is commonly regarded as the "bible" for this field.

This will be a long term "work in progress" report. The index table below will direct you to new S-100 boards built or being tested.   See each boards section for more details.

Readers such as yourself are encouraged to participate either directly by contacting me via e-mail or via the forum on this site.

Here was my starting point for a S-100 system built with boards from the 80's. With this as a basis over time, we will swap out many of these boards into new more exciting and efficient boards using more modern IC's.
