Macintosh Plus

リサフランク420 / 現代のコンピュー

main

This is a Macintosh Plus ED I bought on an eBay auction. The ED stands for education, which I assume was the market target for this line of Macintosh. More info here.

It was sold with a shiny Apple M0110A and a M0100 mouse.

At this point there wasn't much I could do with it. The previous owner of this machine provided 4 floppy discs with useless software for configuring printers and networks, but luckily for me I could load a working System 6.0.8 to play with. Still the only two useful apps on this yoke were a Calculator and TeachText.

Big Mess O' Wires to the rescue

Few days later after playing with the calculator almost every afternoon for some solid 5 minutes, I was still struggling to justify the expensive purchase. Decided to go online and looked for possible ways to emulate a floppy disk or a hard disk drive in order to play some old games and programs.

I discovered pretty quick that the great Steve Chamberlin made a gadget which was doing exacly that!

So as a second Christmas present I bought myself a Floppy Emu. I really can't tell the joy of having a fully working Macintosh Plus and the possiblity to load old software into it. Notice as a usual rite of passage, for any old computer I own, the Prince of Persia gameplay :)

Photoshop 1.0

Another experiment I decided to try was loading the first version of Photoshop, or to be precise the 0.63 and 1.0.7. It honestly took me a while to find a good copy online. Useless to say it's some really fine piece of software for its age although I did encounter some unusually slow loading bars when rendering some pictures.

The final test was to export a picture made with MacPaint onto a modern operating system in order to upload it on my website or simply to see if I could do it. Long story short I actually achived this by:

  • creating the picture in MacPaint
  • opening the picture in Photoshop 1.0 and exporting it as a readable format (CompuServe GIF)
  • saving the gif on the hard disk emulated with Floppy EMU
  • transfering hard disk image file from the SD Card to my Macbook Pro
  • loading the hard disk image into Mini vMac
  • exporting the actual gif image inside the hard disk using ExportFl

And boom here's the final picture. Now open it with an hex editor and read the first 6 bytes ;)

Here's a full detailed explanation of how I accomplished this experiment: https://system31.simone.computer/blog/the-mascot

While here's a small tutorial I recorded during the pandemic:
