You really ought to, but then again, I’m a little biased… 😉

Spotted not one, not two, but *three* playable Bandai Pippin AtMark consoles at #VCFMW this weekend. Bonus: a Pippin Concept Prototype on exhibit courtesy of @mac84.bsky.social and @maccy.me

A Pippin AtMark booted into Pippin Kickstart 1.1, indicating its 1.0 ROM and 13312K of RAM. Displayed on a Sony PVM.

Introducing the Pippin Disk Emulator & Game Changer!
The Pippin is back, in BlueSCSI Form!
by Kate Fox, Macintosh Librarian & Eric Helgeson, creator of BlueSCSI

Now you can hold the Pippins entire software library on one SD card. With the new Game Changer menu, you can play any game from the comfort of your sofa.

The Game Changer
• Written in C, built with Retro68 as one fat binary: 68k and PowerPC in the same file.
• It started as Eric’s BlueSCSI Toolbox CD changer. I added the Pippin calls, the AppleJack pad, menu and box art.
• Pick an image and the BlueSCSI swaps it in. The console restarts straight into it, CD or HD image!
• Power cycle and you are back at the menu thanks to the Keith K. Bootloader!

What is on the menu
• Pippin CDs: Tamagotchi, Dazzeloids, Ultraman Action Designer, Power Rangers Zeo!
• Mac adventures rebuilt on writable disk images: Myst, Dust, The 7th Guest, Iron Helix, Jump Raven, Gadget, Spaceship Warlock

The Arcade disk! Load this one!
• One hard-disk image w/ 35 Mac games
• It runs under PEASE, Bandai’s own big-button Pippin shell. The menus were Japanese, so I patched the strings to English by hand.
• Crystal Quest, Glypha III, Power Pete, Prince of Persia, Another World, Flashback, Monkey Island, Loom, SimCity 2000, Tetris Max, Snood, Oregon Trail, and two pinball games!

Controller (Apple Jack Pad)
• Trackpad is the mouse. D-pad is arrows.
• I wrote a small pad-mapper program that swaps in a per-game layout the moment a game opens. Glypha III starts a new game on yellow. Power Pete switches weapons on blue.
• Glypha III on this pad is, honestly, the best thing on the table. Try it!

Bootloader: a fork of the BlueSCSI Toolbox CD changer. Shell: PEASE (Bandai). Boot: Pippin Kickstart (blitter.net). Debugging: DingusPPC.

I made it home from #QuakeCon 2026 ... and so did my "DOOM chainsaw" -- a McCulloch Eager Beaver 2.0. Thanks to @thattomhall.bsky.social, Adrian Carmack, John Carmack, and @johnromero.bsky.social for what I anticipated when I got this off of eBay nearly 20 years ago. Yeah, I played the long game. 😆

Tom Hall signing my DOOM chainsaw at my table in the QuakeCon 2026 BYOC hall

My DOOM chainsaw resting on my table in the QuakeCon 2026 BYOC, signed by all four founding members of id Software.

The three other founders of id Software watch in glee as I pretend to chop Tom Hall's head off (It was Tom's idea!) with my DOOM chainsaw at QuakeCon 2026's id Software Founders Photo Op.

A handwritten letter, on tractor feed paper, that I left in my luggage to and from QuakeCon 2026, which reads:

Dear Friendly Neighborhood TSA Agent:

Yes, there is a chainsaw in my luggage. But rest assured, it is nonfunctional. I bought it on eBay over 20 years ago and it was just as nonfunctional then as it is now. I have not packed the chain, as it serves no purpose, and there has not been fuel in its tank in over 20 years either. But just to be extra sure, two weeks ago I immersed it in hot water to clean out any possible residual fuel that somehow, some way could have survived over two decades.

You may be wondering _why_ I have a chainsaw in my luggage - the answer is a bit dorky but here it is: I am a big fan of the video game Doom, and this particular model of chainsaw is the model for the one used in the game. The creators of this game are reuniting this weekend in Dallas for the first time since 1993, so I hope they'll each autograph it before I put it back on my shelf. As it is fairly rare, I only trust myself (and TSA) to transport it without damage. My hope is that you understand and relate to this.

Thank you for reading & for helping keep the skies safe! Text me XXX-XXX-XXXX w/ any questions. Keith <3

I annually remind my dad of both this one and The Bee-Deviled Bruin. You couldn’t write scenes like this today. 🤣

Day one of VCF SoCal was a resounding success! Come visit me tomorrow for the second day of Mac hacks, featuring preproduction “Twiggy Mac” materials, music notation software, and Quake running on a Bandai Pippin. Hotel Fera in Anaheim, CA from 9-6. 😎

In Anaheim over Valentine’s Day weekend? Come by VCF SoCal at the Hotel Fera for the latest iteration of my “Mac Hacks” exhibit, and play with some very early Mac software that hasn’t seen the light of day in over 40 years. www.vcfsocal.com Here’s a little teaser:

Dug out my TI-86 and put in some fresh batteries after over a year of it being in storage, and discovered to my delight that its memory had retained its contents.

If you’re in Silicon Valley this weekend (Friday or Saturday), swing by the Computer History Museum in Mountain View and say hi. I’ve got a table near the front of the main hall where I’ll be demoing various “hacks” I’ve maintained over the past few years.
