These are all the codes I saw in the video, just to get them down in text: 0000 0001 | 0000 FFFF 0103 097C | 0E7C 24DC 0300 1583 | 0000 1FFA As per the Sad Mac Reference (under the Macintosh Portable section): The first code 1 / FFFF means the ROM test failed. This is some sort of ROM...

Could you post the sad mac code numbers? I know you mentioned they're different most of the time, but those sad mac codes hold valuable information on why the system doesn't always boot. It sounds like there are damaged traces around the board, or a chip that's unhappy, or something's up with...

Hello all, I would also like to submit for community consideration to join the Tinker Different Board of Directors. My qualifications in terms of forum maintenance, administration, and so on are effectively none. This would be one of those "let's teach the new guy" sort of situations on those...

The V1 PCB has now been tested on my Beige G3, and it is working fine. If you're interested in getting one of these converters, DM me and we'll figure it out.

The listing is now public: https://androda.work/product/macintosh-portable-hybrid-module-recreation/ Despite the listing being open, I don't suggest that anyone should rush and buy one. First, run through the pre-check steps mentioned before to see if your portable has any motherboard damage...

The PIC12F1840 which is targeted by Tashtrio does not have USB hardware. I understand that this limits the usability somewhat, but it's still useful to have a reference PCB design.

This is a reference PCB design for the "tashtrio" project my lampmerchant / @Tashtari . PCB is licensed Creative Commons Non-Commercial, and Tashtrio is licensed GPL V3. Tashtrio allows you to use PS/2 keyboards and mice with your Macs. PS/2 peripherals may or may not be more available or...

Production has started on the hybrid recreation PCBs, version 2 (adjustable A/D line output). Once these are done and tested I plan to open up the listing. I'm using this version in one of my Portables, and the previous version (without adjustable A/D line) in another one.

Currently no plans to use a Gotek or similar floppy to SD device, because this natively has Ethernet. Makes it much easier to move around the text-file versions of the analysis output.

Having re-watched the Tinker Different launch video, transparency and a lack of bullying are the main messages I see. In terms of transparency, I will agree that we are lacking some things that could be expected. * Board meeting dates should be posted publicly and the minutes of those meetings...

Sure. Here are some stock photos: https://www.artisantg.com/TestMeasurement/56270-18/Keysight-Agilent-16702B-Logic-Analyzer-Mainframe Attached are the unit with the cover removed (had to take that off to get to the display), and front.

Quite some time ago I picked up an HP 16702B logic analyzer frame, and have used it for a variety of projects. But all this time, it has had one very annoying fault: the built-in display was not working. That's why it was priced so low, the used equipment wholesaler thought it was irreparably...

Wow, this is great information. I've never used any of these tools before (other than Ghidra) so it might take me a bit to get set up and understand them. It also sounds like we'll need a dev rom board to try and increase these settings, I would guess that ROM patches can't do it?

This is the core problem: a repeated 5-flash (pause) 5-flash means BlueSCSI cannot communicate with the SD card. It's a little odd that a log.txt is created at all if you're getting 5-flash. Did you try this SD card in a different BlueSCSI in a different system before the Classic? If the...

DRAM chips on the eMate 300 motherboard are 2x TC51V4260. These are 256k x 16 chips, likely wired as two banks of 256k at 16 bits wide. This doesn't exactly explain the 900k of DRAM reported by the eMate in base configuration. My guess is that they are calculating it not based on bus width...

This time while testing the production modules, I measured the wait time. Varies between about 50 seconds and 1 minute 30.

Here's the documentation I mentioned, which runs through checking resistance to things around the hybrid and doing some voltage checks with the battery connected (but the system otherwise turned off). If some people could read this and tell me how terrible it is, I would very much appreciate...

If this makes me a hoarder, then yes. https://tinkerdifferent.com/threads/androdas-finds.893/post-7170 Plan is to fix them all up with new display ribbons, upgrade with DRAM+Flash cards, and then resell. Would rebuild the batteries too if I had a good printable design for that (or a battery...

Say hello to the 'integrated hybrid tester platform'. Includes three dedicated little voltage meters for (top to bottom) battery, A/D line, and the main 5.2v rail. Three switches are also on there for enabling/disabling 12v, -5v, and the "hichg" line. All hybrids will be tested on this for...
