OT: Control board

Good morning
I have just completed the assembly and test of a Stamp-controlled PC board
designed for model train control. The board has 10 low-actuated inputs which
can be driven by another microprocessor with serins or by a momentary switch.
Any Stamp except the BS1 can be used,
depending on your memory requirements. Pbasic 2.5 must be used.
If MPU driven by serin commands, up to 52 single byte inputs will produce up
to 52 combinations of relays closures, with 20 relays available for selection.
If switch controlled, any of 10 momentary switch closures will produce any
combination of relay closures, with 20 relays available for selection. Relays
can supply up to 125VAC (isolated) at 2 amps to peripherals
with an external AC source, or up to 48VDC (isolated) at 2 amps with an
external DC source.
The board also has 10 high-actuated inputs which are micro-processor driven.
Up to 1024 inputs are possible, resulting in up to 1024 relay closure
combinations, with 10 relays available for selection. Relays can deliver up to
125
VAC (isolated) at 2 amps to peripherals with an external AC source, or they can
deliver up to 48VDC at 2 amps (isolated) with an external DC source.
Potential users should be familiar with multiple shift register operation and
ULN2003 Darlington arrays.
Sample code snippets are available.
if interested, please contact me off-list.
