Is it abandonware?

seems like it is still supported.

Q.What are the system and hardware requirements to run WiggleWorks-español for Solares Network?

A. WORKSTATIONS
A Macintosh LC III or later
Mac OS 7.0 or later
At least 20 MB of available hard disk space
At least 5 MB of available RAM (8 MB for Mac OS 7.5 and later)
A monitor with a minimum resolution of 640 x 480 that can display at least 256 colors
Headphones (optional but strongly recommended), or internal or external speakers
Internal or external microphone (optional)
SERVER

A server tower with 10Mbits/sec data transfer rate
At least 32 MB of available RAM
Server hard disk space required to store WiggleWorks-español for Solares books and installer*:
Program Installer 26 MB
Kindergarten (12 books) 103 MB
Grade 1 (6 books) 76 MB
Grade 2 (6 books) 94 MB
All grades (24 books) 273 MB

*Some additional hard disk space is required to store all class files and, by default, student and teacher files. This amount will vary depending on the number of users and the amount of work saved by students.

Note: WiggleWorks-español for Solares will not run over a LocalTalk network, and Mac OS 7 file sharing is not supported. As with all server-driven operations, performance speed may vary depending on the number of users accessing the same item. Please also note that books being run from server-attached external CD-ROM drives will run noticeably slower than those run from a network-based CD server (tower).

Edit: Replaced 'xxx 7' by Mac OS 7 - IIGS User
