![]() It includes BBEdit 2, CodeWarrior 4, GraphicConverter, Hotline, KPT Bryce, Netscape, and lots of games. Instead I used an approach similar to uploading to send the contents of a third ExtFS “Saved” directory, which can then be persisted using IndexedDB on the browser side. Figure 3: System 7.0.1 disk images Figure 4: Mounting disk images Figure 5: Welcome Figure 6: Wrong drive Open the Legacy Recovery Drive (figure 3) Open the Mac OS folder (figure 3) Open the System 7.0.1 folder (figure 3) Run the Net Installer Script. While Emscripten has an IDBFS mode where changes to the filesystem are persisted via IndexedDB, it’s not a good fit for the emulator, since it relies on there being an event loop, which is not the case in the emulator worker. Install the full version of 7.0.1 + tune-up 1.1.1. There is also basic prefetching support, so that sequential reads are less likely to be blocked on the network.Īlong with some old fashioned web optimizations, this makes the emulator show the Mac’s boot screen in a second, and be fully booted in 3 seconds, even with a cold HTTP cache. Using content addressing makes the large number of identical chunks from the empty portion of the disk map to the same URL. Manually chunking (as opposed to HTTP range requests) allows each chunk to be Brotli-compressed (ranges technically support compression too, but it’s lacking in the real world). Filesystem requests from Emscripten are intercepted, and when they involve a chunk that has not been loaded yet, they are sent off to a service worker who will load the chunk over the network. After some false starts, I settled on an approach where the disk image is broken up into fixed-size content-addressed 256K chunks. You can see it in action at system7.app or macos8.app.Īt this point I switched my approach to downloading pieces of the disk image on demand, instead of all upfront. The hardfiles folder contains the files that are used as fixed hard disks in the emulation. It does NOT support the PowerPC hardware or the MacOS 7 or above.I’ve extended James Friend’s in-browser Basilisk II port to create a full-featured classic 68K Mac in your browser. This contains the images used by the danzeff on-screen keyboard. Note that MiniVmac ONLY WORKS with the older m68k architecture, and therefore, with Mac System 7 and below. Use balenaEtcher (Windows/Linux/Mac) or DD (Windows/Linux/Mac) to write my drive image file to an SD card Insert the SD card in to your SCSI2SD, connect to your Mac and boot, NOTE: for the Plus the SCSI2SD needs to be connected to a power source to work, USB power is the easiest.

You also need a CD of the Operating system that you want to install, and mount that as the Virtual CD. In the ‘File’ Menu in the HFV Explorer Window, select the option to ‘Format New Volume’. For a start, lets format a 500 Megabyte Apple HFS Hard Drive. Now, to format a new Hard Drive File for use in Basilisk II. If you're using Windows, try hfvexplorer program here: Preparing Hard Files for Basilisk II Open the program HFV Explorer from the folder you installed it to. Then, you must somehow instruct Basilisk II to open that image as the Hard Disk. Usual convention for an naming a disk image is to use a. You MUST have that much disk space available on your physical Hard Drive. ![]() ![]() Substitute with the name of the file that you want to create, and substitute with the number of Megabytes you wish to use for the disk image. If you're running Mac OS X or Linux (or any other type of Unix-based OS), use the command (from a command prompt or terminal): Download my bootable 7.5.5 volume image Run BasiliskII GUI On the volumes tab (Figure 1): add the System 7.5.5 volume image as the boot drive. Download Apple’s Legacy Software Recovery CD from the Internet Archive. I haven't actually gotten Basilisk running myself as of yet, but the general idea is that you have to 'mount' the drive image from which you want to boot. I use Basilisk II because it can edit both my drive and volume/partition images, and is my general go to emulator. ![]()
