The Dual RS-232 Serial Board with Audio (non-v5 at this time) and Fan support is now available, in the following forms:
1. Bare Board model.
A two-sided, solder masked board with plated through holes, including parts list with sources. Price: $20 + S/H (cables available seperately from Jack@BadFlash.com for only $10)
2. Hacker-Special model.
Includes the board described above, professionally wave soldered with all components EXCEPT the MAX235CPG chips. It is assumed that the buyer will take advantage of the FREE samples available from Maxim to obtain the MAX235 chips, http://dbserv.maxim-ic.com/sl_requests2.cfm Onboard sockets allow the user to simply plug-and-play with their chips. This board comes complete with the 6 cables required to fully utilize all features of the board (both serials, and the audio), along with 4 adjusted grip length fasteners with spacers to allow the board to be stacked with the modem.
Price: $45 + S/H
3. Pay-and-Play model.
This version includes all features of the Hacker-Special model described above, INCLUDING the MAX235CPG chips. This is offered for individuals who have more money than time, and would prefer to simply order the completed ready-to-run board.
Price: $68 + S/H (The retail price of two MAX235CPG chips is $32, so this is still a bargin)
The boards may be preordered now from Jack@BadFlash.com with deliveries beginning in approximately 12 business days.
Cudos go to Jack for supporting the board offering, for testing the prototype, and for working very hard to produce a 6 cable package for a VERY reasonable price of only $10. His efforts have contributed significantly to allowing the price of the board to remain low.
The board uses a unique staggered stacking arrangement, allowing it to be stacked safely on top of the existing modem board, with no R/F shield trimming required.
For dual serial operation, the modem must be removed to free COM1.
For single serial operation, the modem may remain in place and in use.
For single serial operation, only one MAX235CPG chip is required.
The audio is functional for all installations.
Power connections are provided to support the fan.
Header pads are provided for user-installed header posts to allow the use of TTL level lines from COM2, as well as the RING, RST, MIC, SPKR, GND and +5 lines not used from COM1.

We have tried to keep the prices low to cover our costs and to have a little fun, however these prices may be adjusted up :( or down :) depending on interest, inflation, and the performance of Jacks international investments ;)
