I used to believe that Personal Software only published Zork (actually, Infocom's Zork I) for the TRS-80, but I finally stand corrected. This Zork Personal Software (Apple II) auction on eBay was all the proof I needed. Infocom's early publisher did apparently provide the Apple II with some quality text adventuring, that has aged into a really obscure rarity. Then again, a starting bid of $1495.00 does seem a bit steep; most Personal Software Zork auctions (for the TRS-80, mind) I remember never reached $1000. Oh, and the seller does ship worldwide.
