The Apple II had a monitor you could reach via:
]CALL -151
and you could type a program such as:
*300:AD 30 C0 88 D0 FD 4C 00 30
but while there was a disassembler (300 L) there was no assembler!
Fortunately, if you had Integer Basic, you could do:
]INT
to get to Integer basic, then go into that monitor:
>CALL -151
then jump into the "mini assembler" inside Integer Basic:
*F666 G
and now you're in something resembling an assembler:
!300:LDY#$0
!302:JMP$309
!305:JSR$FDED
!308:INY
!309:LDA $320,Y
!30C:BNE $305
!30E:JMP$FF65
!$320:48 45 4c 4c 4f 20 48 41
!$328:43 4b 45 52 20 4e 45 57
!$330:53 21 00
!303G
