This homebuilt microcontroller board uses a 68HC11A1 MCU with 64KB SRAM.
I used an alternate Reset supervisor IC temporarly because the Motorola
MC34064 was out of stock in my area. (I couldn't wait for a mail order
then). I'm using 32Kx8 SRAM IC's found on PC Mainboards. they very cheap
to come by, when buying up dead mainboards. I use a memory diagnostic downloaded
into the Internal ram to check each SRAM to verify they're good. I power
the microcontroller using the 6V Regulated supply for the robot. Hopefully,
I can put this on a PCB and save on the wires.
Any questions, suggestions, or tips are welcome.
