I flash a lot of chips. ROMs for the SE ROM-inator, GALs for the Grappler Minus, 4-chip sets for the ROM SIMMs. All of it goes through an XGecu T48, and the T48's own software, Xgpro, only runs on Windows. So every time I needed a chip, I was booting a Windows machine. minipro, the open source driver for the XGecu programmers, does run on the Mac. But it's a command-line tool, and typing SST39SF040@PLCC32 into Terminal for the fiftieth time in a day gets old. So I wrapped it in a Mac app....

While I was editing ROM images for the SE ROM-inator I'm developing, I kept thinking it would be handy to have a Mac SE I could open in a browser tab. So I made one. The original vMac emulates a Mac Plus, so I changed the build to match the SE. Other than that it's Mini vMac put on the web as is, and it works the way Mini vMac always has. You can load your own disk image, install and edit things on it, and download the finished file. There's nothing to set up. Right now I think it's the...

The SE ROM-inator can now reflash every part of itself on the Macintosh SE itself, including swapping the main ROM between the early SE version and the FDHD one. The flash tool for the original ROM-inator is an excellent program, and I had to get it working on the SE ROM-inator one way or another. Where it started Steve Chamberlin started all of this, and his Plus ROM Flash Tool is the reason any of it exists. It runs on the Mac itself, unlocks the two flash chips, and rewrites them in 128K...
