Thanks to all who offered to test my port of Zork I to the PET. As a
result of those tests, I decided the quickest course of action to unjam
the project was to port it to BASIC 2.0 from BASIC 4.0 because of lighter
use of the zero page. I can now announce success. It works under VICE,
so I expect it to work under the real hardware, too.
You will need a 32K PET with BASIC 2.0 ROMs (3032, 32K 2001, etc.) and
a 170K floppy drive (3040, 4040, 2031). The *temporary* URL of the
binaries is http://www.infinet.com/~erd/retrocomputing/PET/ Eventually,
when all is working, I will be releasing this as a patch to the original
Infocom disks. Therefore, please do not widely circulate this URL. Consider
it a public beta, not a full release.
