[comp.edu] Shareware Scheme for Macintosh -- new release

freeman@argosy.UUCP (Jay R. Freeman) (01/16/91)

    There is a 5 January 1991 upgrade of "Pixie Scheme", my
shareware Macintosh Scheme interpreter, which is a rather
complete (but slow) implementation of "R3"-dialect Scheme:  Its
main lack is numeric types beyond 32-bit signed integer and 32-
and 80-bit floats.  New this release is on-line help, a wimpy
compiler, miscellaneous enhancements and some bug fixes.

    Pixie Scheme requires a Mac Plus or better, 1 MByte of RAM
and Macintosh system software 6 or newer.

    The distribution includes two program versions (one uses
68020 / 68881 code) and a HyperCard help stack.  It is too big
to EMail -- 600 KBytes compressed, more after (eg) BinHex.

    I gave copies to BMUG and to Boston Computer Society
Macintosh Group at the January 1991 MacWorld Expo.  I mailed
copies (postal service) to everyone I know who has put Pixie
Scheme on a bulletin board or archive.

    Until 1 March 1991, I will mail you Pixie Scheme if you send
me an 800 KByte disc, a mailer and return postage.  (Non-US:
about five international reply coupons.)  If you take this offer
you may ignore my (one-dollar) shareware donation request.

    USE A STOUT MAILER!  Discs rub through plain envelopes in
the mail, and stamp-cancelling machines damage them.

    (I hope this announcement is appropriate use of the net; I do
Pixie Scheme essentially as a public service.)
