Field Test Unit Software
To use the 8k 6264LP RAM supplied to increase the FTU memory to 16k switch the FTU off and remove the cover of the chip socket on the back of the FTU.
Replace the FTU ROM with the RAM chip and change the memory select switch from ROM to RAM. Replace the cover press the reset button on the back of the FTU and switch on.

2.3 FTU INITIALIZATION
If for any reason the FTU programs need to be loaded, the following proce- dure should be used:-
1.Using a pencil, press the RESET button at the rear of the FTU. (This is a Master Reset, so ALL PROGRAMS WILL BE LOST).
2.Connect FTU to Cassette Recorder with Model 6302A
software cassette tape inserted/rewound and ready to use.
3.Press ON/BREAK key on the FTU. The message “14940 Bytes free” will appear. (Note: at least 14940 Bytes are re- quired to operate this software, more ‘free’ bytes are fme).
4.Type:- FSET 10000 Return (2300 if using PLOT/PLOTX)
5.Type:- CLOAD “FTUC” Return (system should respond with ‘Found FTUC’ and then continue to read the program FTUC from the cassette tape and store it in the FTU)
6.Type:- SAVE “FTUC” Return (to save the program FTUC permanently in the FTU’s RAM file area.) SAVE “LOAD/UNLOAD”
7.Repeat Steps 5 & 6 above to Load & Save programs “LOAD” and “COPY”. Program “PLOT” may also be loaded if there is sufficient RAM in the FTU [in this case, “PLOT” should be LOAD(ed) and SAVE(ed) first, then “FTUC”, “LOAD” and “COPY”).
