View source for WTI remote power strip

I have a Western Telematics, Inc RPB+ remote power strip.

On the outside:
* 5 switched AC outlets, individually controllable
* Can switch up to 15A on one port, up to 15A for all ports.
* 9 pin RS232 port (you need a null modem cable to connect)
* Dip switch for setting baud rate
* An LED for each outlet on the front panel

Inside it has:
* a PIC 16C56 microcontroller, in a socket
* 5 nice relays and associated drivers to interface to PIX
* a 555 timer
* an ADM232 on the serial port
* a power supply

A PIC 16C56 has:
* 18 pin DIP
* 1.5K memory
* 25 bytes of RAM (whew! takes my breath away!)
* 1 8-bit timer
* It's OTP = one time programmable

To substitute a flash device I could drop in a 16F628A, then I'd get
3.5k of RAM and 224 bytes of RAM.
