S100Computers Boards Status and Order
List
As you can see in other sections of this site I and a handful of
others continue to make custom S-100 boards for our own
use. A lot of work goes into designing and manufacturing these boards.
Typically they start off as a point to point wire (or wire wrapped) soldered
prototype board. Then a long process at arriving at an efficient schematic is
carried out. A first prototype board is then manufactured. The process
may have to be repeated before a final commercial quality board is
made.
Realizing a number of others may want to use these boards we typically open the
final "commercial" board to others that may wish to obtain them. These are high
commercial quality but bare S-100 boards. You have to add your own IC sockets
chips etc. A schematic and assembly instructions is provided for each board
however on this web site. For more information about ordering
S100Computers boards please see
here. Please remember however this is
NOT a commercial venture.
Here is a brief description of all our current S100 bus boards:-
S-100 Buffered Prototype
Board
This
is a fairly old S-100 Prototype Board that is designed to help take away
the initial drudgery of building S-100 prototype boards. We have laid
out the board so all the address and data lines are buffered through 74LS245's
or 74LS244's. Most of the common S-100 bus control and status signals are also
buffered. So the user can right away get down to building useful circuits
without the bus connection/IC overhead. Also the board is arranged so
a daughter piggyback (no S-100) board can be attached via a series of connectors.
This way you can have cheap simple test boards made before you "burn" your own
real (more expensive) S-100 board.
If you have a real interest in a board(s) let us know. Note these are
bare boards. You add chips and other components yourself. There is a wait list
for additional boards if and when demand warrants.
A second improved version of this board has been made.
See here
for more information. Here is a picture of that board:-
Basic S-100 Prototype
Board
This a basic S-100 prototyping
board (no buffers etc.) has a 9"x4.5" area of PTH for wire wrap or point to
point wiring of prototypes.
All pins are exported and includes circuitry for
three voltage regulators, +5V, +12V, and -12V.
The SCRs are optional and can be modified by the
builder as desired.
The S-100 prototyping boards are $25 each plus
$3 shipping in the US.
These S-100 prototype board PCBs are currently
all sold and in the hands of builders being tested and used.
S-100 Motherboard
