Overview

{{Off topic|date=February 2024}}

Mini vMac, vMac's spinoff, is still being maintained and developed by Paul C. Pratt. Currently Mini vMac supports Macintosh 128K, 512K, 512Ke, Plus, SE and Classic, with active development for Macintosh II, Macintosh Portable and PowerBook 100 support. Due to complaints about the rarity of the original II,{{Citation needed|date=March 2009}} it also accepts Macintosh IIx and Macintosh SE/30 ROM files.

vMac and Mini vMac require a Macintosh Plus ROM file and Macintosh system software to work. Macintosh ROM files are owned by Apple and cannot be legally distributed.{{Cite web |last=Pawlowski |first=Weston |year=1998 |title=Most Common Questions and Answers |url=http://www.vmac.org/cgi-bin/suwalski/open.cgi?/home/suwalski/public_html/files/0001.vkb |url-status=dead |archive-url=https://web.archive.org/web/20031226222705/http://www.vmac.org/cgi-bin/suwalski/open.cgi?/home/suwalski/public_html/files/0001.vkb |archive-date=26 December 2003 |access-date=16 February 2025 |website=vMac.org}} However, the Windows and Unix ports of vMac (not Mini vMac) support the Gemulator ROM board from Emulators Inc., which allows users to add genuine MacPlus ROM chips to their x86 machine via an ISA expansion slot. This board can also support ROM chips from other early Macintosh systems, but the publicly released versions of vMac only supported the Macintosh Plus.{{Citation needed|date=February 2025}} Macintosh system software is available from Apple's Support Downloads Website.{{Cite web |date=November 2012 |title=DOWNLOAD.INFO.APPLE.COM FTP Site |url=https://archive.org/details/download.info.apple.com.2012.11 |access-date=16 February 2025 |website=Internet Archive}}

As mentioned, Mini vMac also requires a specific ROM image for the computer emulation desired. A software application for these 68000 Macs may be downloaded from the Mini vMac website for retrieval of a system's ROM image, along with a complete tutorial for locating an old Mac, retrieving the ROM and working with disk images.
