"I saw a cryptic comment — I think in COMPUTE! #10: "PET Exec Hello" by Gordon Campbell. Second paragraph: POKE 59458,62 (this may damage your machine). Can I damage a PET with POKES? ? It scared me. We just got a (used) PET —Original ROMs. I heard you have published a PET book based on old issues of COMPUTE!. How can I get this?" Felix Rosenthal
You can damage the computer with this POKE. Luckily, it is the only POKE which is known to be risky, as far as we know. You can POKE freely anywhere else. For a more complete explanation of this peculiarity, see the warning in COMPUTE! #14, pg. 63. To answer your second question: yes COMPUTE! is publishing two such collections, one for PET and one for ATARI. These books contain much from the early, out-of-print COMPUTE! issues (as well as some previously unpublished pieces). For ordering information, see the ads elsewhere in this issue.
