Hey, this editorjob is no bedof petunias, youknow.

Allowme to levelwithyou. I'm sitting here in mypadded

(this isthe truth) office outsideWayne, Pennsylvania. Right

now I'm all alonewith my trustyCBM 8032 (you donot use

a typewriterwhenyou workfora computercompany—a

wordprocessingprogram calledWordcraft is myonly

writing tool), trying todecidewhatyouwan! toknowsowe

canget it out toyou. I'mmaking semi-educated guesses.

My eyesare chronicallybloodshot from staring at myCRT

forprolonged periods. Not onlythat, but the incessant

blinking o) mycursor is makingme a nervous wreck. It

makesme feel as ifmyCBM is tapping its foot impatiently

whenever I pause, Somuch forcomplaints.

Thesemi-educated guesses thistime coversomepretty

varied topics, fromcomputershoppingto rhinoceros

games. To paraphrase Mr. Lincoln:we're hopingsomebody

will find everything interestingand everybodywill find

something interesting. Mypersonal favorite is the story

about ScottAdams' Adventure Games, but that's just

because I had so much fun doing the research.

Thanks to all ofyouwho'vesent us letters. The more

inputwe get. the less we have to guessatwhatyouwant

and need, I'm sorrywe can'tanswerall of them, but if

it lookslikea lot of people are having the same problem

orwant the same information, we'll get it into POWER/PLAY

Ifyou don't find it here, however, find (orstart!) a user

groupinyourarea. Usergroupsare terrific resourcesfor

novicesandold-timersalike.

So herewego with the second issue. READY? LOAD,

RUN
