Robert,

Your module is very nice, but it has more capability than I need.

At present I use the Parallax SX48/52 Proto Board for some applications, but I would like to have the ability to
replace just the SX48 if there is a problem. 

Here is a general description of what I am looking for. Perhaps other folks may have similar needs.

SPECIFICATIONS:
Similar to discontinued Parallax SX52 con CARNE module
Selling price: $39 max, assembled and tested

Board should contain:
1. SX48 microcontroller
2. 4 pin programming header, to interface with SX Key or Blitz
3. 3 pin socket for resonator
4. 4 pin socket for resonator caps or resistor
5. 2 rows of  0.019"dia  pins on 0.1" spacing 
6. 21-24 pins on each side
7. SX48 pins to be fanned out:
     a. All I/O ports, 36 total
     b. Vdd, Vss
     c. RTCC, MCLR
     d. Osc1, Osc2 
8. All pins silkscreened with names 
9. No other on-board chips are desired

Thanks.

DaveG
