4) You can program this code on a 27C256 EPROM but in such
case you must left PIN 1 of the ic OUT OF THE SOKET 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).

the patched one, the MFJ 1278 will respond

To work at 4800 BAUD Patch 7E3F:48
