This is interesting :) It has '70s vibes

During the group buy, a lot of people were interested for a color closer to our old gear (white/beige/light gray), here is what it looks like Activity LED is orange-ish like the Mac II era HDD ones, whereas on the blue one LED collar is sea-ish blue

Glad to hear about another success! After looking at this LED issue, the error is mostly on my side, sorry about that. What happened: the SSL-LX5093SRC39240 is similar to the SSL-LX5093SRC/E except cheaper and with short leads. Except the LX5093SRC39240 pictures show a LED with long leads...

From my understanding, yes that's what the firmware is doing

as @Tashtari said, the device as you know it (that translucent bluebox that I posted that @Mu0n built in his nice video) is unfortunately audio only (Internal Mic or external line in). Long answer below Citing MIDI in that small box was hard and the BOM was going a little crazy (need other...

That's weird. For the panels, you can indeed go for the bare minimum as it was designed that way. Check "Select order location" to have the build number on the invisible side. Edit: just understood that you are doing a group by. Please keep in mind that we didn't check compatibility on a lot of...

T48 only (and probably T56). Unfortunately the PIC12F1501 is too new for any TL866. PICkit3 works well as well.

I can do it, but it gets expensive. Group buy thread is here

Now your old Mac can hear you scream! Introducing... TashRecorder! Elevator Pitch This a compatible clone of the Farallon MacRecorder , but as far as the software is concerned, it's the real deal! Both @Tashtari and myself (since 2021!) had this project on our own, one of us having a working...

Thanks, will PM you when it's ready

Nice ! Yes, that's what I've found as well (with the community help) 3 screw versions are ALPS ones, 4 or 8 screws are NMB ones This matches the information on Deskthority here

Usually LEDs (most, not all) do have a flat notch on them. It should match the notch on the PCB silkscreen My bad, you are right. It's 2mm spaced You are welcome ! I've never seen the 341-0875-A. Where did you find it ?

Sure. For this project with this controller (341-0001) there is no difference. The controller is versatile and has everything built in (Pull-ups, current limiting resistors…) Using another controller however, pinout issues aside, would maybe need (at lease) a resistor network on the keyboard...

Thats weird, maybe the LEDs are backwards ? This does look so good with the Kingston Trackball ! The PCB was designed to use an angled right 2.54mm header or a connector like this (see the silkscreen). I soldered the cables because I've got no patience. The internal connector is a good idea...

Might be. The loop resistance of a membrane "switch" is about 100-200Ω and act as a current limiting resistor. When switching to standard switches, it goes down to 0Ω, so you have to be careful in some cases to not short the controller. The 341-0001 has 33kΩ internal pull-up resistors, so 33kΩ...

Hello, Nice detective job ! I'm not 100% if Apple cables are all the same, but you got that right. The letters stand for : - G = ground (green) - V = VCC / +5V (red) - A = ADB bus (blue) - P = Power Trickle (white) - E = Earth / Shield (thick black) Also thanks for your build log, it will...

Thanks to everyone photos who helped: ANSI version of the PCB ! It turns our the controller is dual mode, and will boot into ISO or ANSI mode when installed in the respective PCB. You can find the ANSI Gerbers files here

Thanks @RetroTheory and @François I didn't know about the ALPS clone. About the NMB one, it looks like that's really a different controller. The KS88C0504 has internal pull-up controllers, while ion the NMB PCB, it's external. Also a few more things that aren't there on the ALPS version...

Was working on this since a few weeks. Since it works, I'm gonna post that here. One common issue I and a few other folks have is that while Apple Extended Keyboards are great (and still my favorite keyboard), they are kinda big for test benches or if your retro corner is small. That and we...

My vote goes for the Radeon 7000. I will echo what @Stinkerton18 said. I have both (reduced ROM and full ROM). Reduced ROM works better in a New World Mac as primary/secondary card. You can also flash old Sun Radeon 7000s (SUN 375-3290-01) as they have a 128K ROM as well.
