Flap Flap Flying Toasters on Fruit Jam 🕊️🍞💾

We grew up with a Mac Plus/512K, so getting the Pico-Mac 68000 emulator https://github.com/evansm7/pico-mac working on Fruit Jam https://www.adafruit.com/product/6200 with 1MB+ of RAM was a high priority for those nostalgic vibes.

We've got HSTX DVI output plus PSRAM working https://github.com/jepler/pico-mac/tree/rp2350-fruitjam, which means 4MB RAM—that's the most you could get into a Mac Plus and enough to run System 6! https://en.wikipedia.org/wiki/System_6 Please note that System 7.1 was the pinnacle of software design, but System 6 was also pretty good. System 6 had some nifty features, such as the "Extensions" and "Control Panel" system programs, like After Dark with the famous Flying Toasters https://en.wikipedia.org/wiki/After_Dark_(software).

Note that we're still working on audio, so you can see the high byte of the memory space used for audio that we've mapped into the video RAM for visualization. http://www.mac.linux-m68k.org/devel/plushw.php has more details on how that works - its 8-bit PWM audio reads "one byte per scanline." We'll have that output on the I2S DAC for speaker or headphone output.

Playing Our Childhood Mac on the Fruit Jam 🍏💾

We grew up with a Mac Plus/512K, so getting the Pico-Mac 68000 emulator

working on Fruit Jam

was a high priority for those nostalgic vibes.

We've got HSTX DVI output plus a USB keyboard and mouse

and with a little effort, we built a 2-megabyte "disk" with some of our favorite games and apps:

MacPaint!

Lode Runner!

Shufflepuck Café!

Adafruit FruitJam is a Mac 384K 🍏💾

The FruitJam board has an RP2350, dual USB ports over PIO, DVI output from HSTX, and the ability to emulate some classic computers. In this demo, we're using it with the Mac 128K-But-With-384K-Instead

It's not quite a 512K or Mac Plus—which had 1 MB of RAM—but it does have the same 68000 core and is running a Mac Plus ROM, so once we get PSRAM going, we could easily expand to much more RAM. Right now, we can run Finder 5.1 and test out the mouse and keyboard, which both work flawlessly. This is super fun—we can't wait to get some of our favorite old games working! FruitJam is still a work in progress; we have to revise the PCB to fix some errors, but you can sign up here to be notified when we get them in stock

MacPaint Art From The Mid-80s Still Looks Great Today via decryption's blog [Shared]

I really enjoyed browsing the BMUG's CD-ROM and discovering early 80s art made in MacPaint, so I browsed all 18,000+ MacPaint images on Discmaster to see what gems I can unearth. Here is some that I found.
