Any slot except 3 should work fine

Normally you'd use the programs that came on the floppies, however the manual
gives  this program to read the time. Substitute the slot # for the ?s

10 PR#?: IN#?
20 INPUT  "%";T$
30 PR#0: IN#0
40 PRINT  T$

For setting the time try this program if the cards in slot 4
10 D$=CHR$(4): REM CNTL/D
20 PRINT "TIME? MM W DD HH MM SS";
30 HTAB 7
40 INPUT "";S$
50 PRINT D$;"PR#4"
60 PRINT D$;"IN#4"
70 PRINT "!";S$
80 INPUT "%";T$
90 PRINT D$;"PR#0"
1OO PRINT D$;"IN#0"
110 PRINT T$

Don't forget to set the switches

Don't know. It's on my list of stuff to OCR, however
there's over a thousand pages of stuff I'd like to do first.
