And the Apple ][ equivalent:
 *300: A0 00 B9 10 03 F0 06 20 ED FD C8 D0 F5 60
 *310: C8 C5 CC CC CF A0 D7 CF D3 CC C4 8D 00
 *300G
 HELLO WORLD

Personally, I usually loaded the mini assembler into the language card.
I even doctored it a bit to add some features.  Since I started out on
a vanilla ][ with INTBASIC, I couldn't stand it when the miniassembler
went missing when I "upgraded" to a ][+.
