Post by: zefrenchtoon on January 27, 2022, 11:28:42 PM
Hello everyone !

A little post to share you a link to a japanese blog entry that shows how to add an ADB connector to a Yikes G4 !

This is surely useless but maybe it can be usefull to someones ... :)

Here is the link:

Maybe I will try on mine if I find the time and if I'm brave enough to try  -afro-

Thank you so much zefrenchtoon

Your post could not have been better timed. Yesterday I noted down to contact Japanese Mac OS 9 forums and bloggers.

I signed up and wrote a comment on Kiro's Mac Mods latest blog, just now and invited him here.

Please never hesitate posting your finds, whatever you find -one man's trash is another man's treasure.

Great find  (

So there actually IS a Japanese Mac OS scene?

I always figured there has to be one given how crazy popular the Mac was there during the 90s. But they appear to be staying pretty much among themselves, little news coming out. Would definitely like to hear some more about projects, blogs and such.

Let me introduce you a little here...

And it is the only seller of ROM-Inator Resurrections (originally BMOW).
And I made a new overclocking device for 68K. This is selling very well these days.

And this is our website:

I'm not active here, but quite active on TinkerDifferent, Discord and Facebook...
If you have any questions, feel free to ask.

Title: Yikes ADB
Post by: FBz on January 28, 2022, 10:01:24 AM
Thanks Zefrenchtoon!

Very helpful link for those with a Yikes machine (or mobo) wishing to add ADB to those Yosemite-based Yikes motherboards. Fortunately, I’ve no Yikes machine here or I’d likely be huffing solder fumes again to install that ADB port on a machine that Apple only offered an ADB option for, when the Yikes was released.

Apple removed the ADB port on the Yikes and then offered to sell it back as an option?

Ahh Apple, cut production costs and also create another revenue stream with $$$ optional “ADB upgrade”. Think Different… indeed. I skipped the Yikes here and got a Sawtooth. (But that doesn’t help mopar300m.)

Admittedly, I’ve often considered the Griffin 2001-ADB iMate /Universal ADB to USB adapter because I do miss using the old beige Apple Extended II Keyboards with the G4’s. (BUT have you seen the prices on those lately?) And sure, there are other ADB to USB D-I-Y options to make your own adapters.

Again however, for those with a Yikes - Kero’s MacMods provides a way to use those old ADB devices (including joysticks) with ye olde Yikes. Great link Z! And a very warm welcome Kay Koba of Kero's Mac Mods.

Still, originating here with mopar300m weighing a change from a failing B&W Rev.2 mobo (scarce) to a possible Yikes mobo (less scarce?) - I’ve still yet to see any great advantage in such a substitution. Especially as mopar300m already has a 600 MHz/1 MB XLR8 Machspeed G4 upgrade in his G3 B&W.

Now I wonder if it might possibly be easier / more advantageous for Yikes owners to simply downgrade their mobos to a B&W Rev.2 mobo with a CPU upgrade and / or overclock the G3?

And yes, Yikes owners would need to drill that hole for the B&W Yosemite ADB port too. ::)

Hi guys, Sorry that my writing will be little different from the content of the post :P

I'm actually Japanese, but I have few friends with active Vintage Mac users right now. And I have something to say additionally. The musical instrument store I joined around 1990 was also an authorized Mac store. It was pretty popular to use the Mac for music in this era. Unfortunately I wasn't in charge of Mac. I was a guitar repairman, but I think I sold about two Macs.
For Mac and Japan, Japan had its own modification and repair methods. It was partly more advanced than the United States, and in fact Simasimac is a Japanese word. Mistic and Takky were also invented in Japan. I'm 50 years old, but I remember that time well.

As for the G4, I own all models except the Cube, and most of them include CPU accelerators or modifications. Most of the G4s are left in my office by friends who are no longer using them...
