Traditionally, Apple 1 (or Apple ][ for that matter) hex dumps look something like:
0300: 25 14 23 84 23 14 16 1B
: FF 9F 1E 1D 1C 1B 1A 19
...
This is suitable for entering straight into the Woz Monitor as a line starting with a colon indicates that the following bytes should be palced in the ram immediately following on from the previous write (or read).
I was having trouble with the paste function in the pom1 emulator, probably due to speed sync issues. pom1 lets you load rom dumps, but it expects the memory address on each line, not just the first.
As always, perl to the rescue :) With the following handy perl one liner you can convert a rom dump file in the usual format:
perl -pe '$base = /^([0-9A-F]{4}):/ ? $1 : uc sprintf "%04x",hex($base)+8; s/^[^:]*:/$base:/'
