Two very interesting things have emerged about the Mac Portable and the Power Manager chip, based on my increased understanding of the Hybrid module through all this research and work. 1: The A/D line voltage, intended to convey battery and charge level information to your system, can kill your...

I've tweaked the mounting bracket for the existing F4Lite V1.1 design, in the hopes that it will work with LC520 style edge connector machines (I don't own one of these systems unfortunately). Looking for a tester or two in the USA, DM me if interested. My eyeball and caliper say that things...

I don't have plans to offer fully unassembled kits unless there's a lot of demand for it. Something totally unassembled can't be tested at all, and I don't like the possibility of sending something out which won't work even when properly assembled. We're dealing with new old stock parts...

A quick update, PCBs for the second production round have arrived but I'm still waiting for the DRAM and flash chips to ship. Once everything arrives here, I'll be able to make something like 25 more upgrade modules.

The listing on my site for the recreation cable is now open: https://androda.work/product/macintosh-backlit-portable-m5126-screen-flex-cable/ Don't have a ton of them, and will order more once these run out.

Here's a link to the eMate display cable, for anyone that feels like testing it currently: https://androda.work/product/emate-300-screen-flex-cable/

My policy is that for any and all laptops where the battery can be removed, it is removed. Store batteries which are nicad, nimh, and lead acid in plastic bags (or containers) individually, double or triple bagged to attempt to prevent any leakage from escaping. These old batteries probably...

Feedback from testers is that the A/D line isn't exactly like the original. Boots and works fine, but the battery meter might only go to 6 or 7 out of 8 bars on the gauge. Fortunately, this isn't a huge issue - I could add a little trimmer potentiometer to the board for people that want it to...

Sure, the original link is still available. I like to use the internet archive for things like this to be more certain that data is still available in the future. The IA page contains the original URL, so you can check the original source later. Much data has been lost to link rot, and...

Not sure what's going on with the internet archive. That link which has the * in it would show me the archive history page with the calendar view of when the page has been saved. But now it doesn't. Makes me wonder if the IA is having issues.

The link is working for me, shows that the Internet Archive captured the URL yesterday. https://web.archive.org/web/20220000000000*/https://marc.info/?l=newtontalk&m=110740915605337&w=2

Found some more information about what's in the blocks of 'calibration data' from NewtonTalk. This post talks about what's actually *in* the calibration section a bit. Not all the information, but at least some of it. And the 'factory calibration lost' message probably has nothing at all to do...

The updated cables have arrived, and the soldering rings for the original connector are much better this time. Far easier to solder onto. If you'd like one, DM me. Currently waiting for test results before making the link generally available on my site.

I have a RAM card project in progress, just need to get my debugging setup in shape first

Something in the eMate's ROM must be involved here to configure the CL-PS7010 go-between chip properly in terms of which memory and flash driver banks to use. It's a strange architecture, with the CPU not directly connected to RAM or flash (maybe not even ROM). The 7010 supports many banks of...

Talked to my friend who has one of the original dram+flash upgrade modules from 'back in the day'. He says that installing and removing it has not caused a factory calibration error to appear. Just a full data wipe every time. This makes me question whether it's really a one-way upgrade. And...

I doubt that they provided instructions on how to remove the module. Based on what I'm seeing it's a one way process, unless a tool can be written to back up and restore those device configuration blocks. A tool to do the backup and restore might be useful in general. Other people have...

I don't understand the question. Two test modules were installed, by Fizzbinn and another tester. They haven't reported any issues. Installing the module *and then removing it* is what caused the 'factory calibration lost' error for me. And I can't think of a good reason to remove the module...

I have now tried a 'hard reset' on my eMate which gives the factory calibration error. The error persists after hard reset. :( According to this post on NewtonTalk, calibration data is stored in the very first block of flash with a backup in the second block (blocks 0 and 1). A hard reset...

I think it's intentionally a one way process when installing the flash upgrade modules. The system RAM upgrades can be removed with no issues. My guess is that there's something in the firmware which "integrates" the extra flash into the system as a whole. Remember that the Newton is based on...
