Wraith Scheme 1.36 released (shareware parallel R5 Scheme for Macintosh)

[Jay Reynolds Freeman]

Today I released version 1.36 of Wraith Scheme, which is a
shareware R5 Scheme implementation for the Apple Macintosh, with
enhancements for parallel processing, by which I mean multiple
copies of the Wraith Scheme application (separate Unix
processes) all running at once, sharing Scheme main memory. For
details, and to download a copy, visit the software page of my
website:

Main website:

http://web.mac.com/jay_reynolds_freeman

Software page:

http://web.mac.com/jay_reynolds_freeman/iWeb/My/Software.html

The software page includes a link to a web-browsable copy of the
Wraith Scheme Help file, and a more specific link to the part of
that file that discusses parallel processing.

Wraith Scheme 1.36 is a bug-fixer for its predecessor, which
incorporates a fix to the platform-dependent bug that I mentioned
on comp.lang.scheme a few days ago. You won't need 1.36 if
you do not see that bug in 1.35.

Barring major bug-fixes or other unexpected circumstances,
Wraith Scheme 1.36 will be the last version of Wraith Scheme
that runs on MacOS 10.4 (Tiger) and will also be the last
version that runs on any PowerPC-based Macintosh.

There is also a version of Wraith Scheme that is a 64-bit
application and requires MacOS 10.6 (SnowLeopard), and will
therefore only run on Macintoshes with Intel processors.
I am aware that it is possible to make 64-bit Macintosh
applications that run on PowerPC processors, but it
takes a G5 PowerPC to run them. I do not own a G5, and so could
not test such an application, and therefore do not propose to
write and release one.

This link is incorrect, and actually leads to the same above-mentioned
Web site when clicked. The correct link follows:

What a pity! My PowerBook is PowerPC-based, and currently is running
Mac OS X 10.5.8 (Leopard).

According to your above "Software" Web site,

Accordingly, can my Macintosh run Wraith Scheme 1.36 (I'm at work
right now, and cannot test it at the moment)?
