NOTES:
1) This is only a PATCH to WA8DED firmware for using it with
MFJ 1278 TNCs. The resultant code is still copyrighted
by Ronald E. Raikes.
2) Code from 61B4 to 61F0 is added to the bottom of the
original firmware so the original data is unknown.
3) BE SURE TO PATCH THE SAME VERSION
these patches only work with the listed version
(Check for original values to match with the listed ones.)
4) You can program this code on a 27C256 EPROM but in such
case you must leave PIN 1 of the IC OUT OF THE SOCKET and
wire it to +5 Volts (PIN 28 of the EPROM).
If You use a 27C512 program the code IN THE SECOND HALF
OF THE EPROM (starting from address 8000H).
5) Remove the original EPROM at position U23 and install
the WA8DED patched one, the MFJ 1278 will respond
you as a TNC2 at 9600 BAUD.
To work at 4800 BAUD Patch 61B6:48 61C6:08
6) With this FIRMWARE you will lose the multi mode capabilty
of MFJ 1278, it is intended to allow you to enjoy programs
like SP in true HOST MODE.
7) The patches listed are 110 if you read less this message is
corrupted get a good one.)
8) The followings new commands are available:
@R0 (Default) Select RADIO 1 port
@R1 Select RADIO 2 port
@A0 (Default) Select VHF PACKET modem
@A1 Select HF PACKET modem
@X0 (Dfault) Select 1200 BAUD VHF PACKET modem
@X1 Select 2400 BAUD VHF PACKET modem (MFJ TURBO ONLY)
@J For software experts only Cause a JUMP to location 7000H.
I have put a EFKISS code here so i have kiss too.
DONOT USE OR THE TNC WILL HANG
(The code to be added at location 7000H to get EFKISS is
available upon request.)

I am in qrt now for info contact IW1QGT@I1HUH.#GE.ITA.EU
**** Note, the 1278DED.ROM is patched for 9600 and ready to go. Do not attempt
to repatch it unless you only want to change the computer to tnc buadrate to
4800. It has been tested with the 1278 on FBBS systems and works great!
