Yeah, what could an eMate do with 16 megabytes of DRAM? I really have no idea, mostly just want to enable other people to do things which I am not thinking of. :) Production will start on the DRAM+Flash upgrades probably a little later this week. And I'll update the product page to mention...

Main Update: The DRAM and Flash chips have now arrived, so I can start production of the upgrades again. Very long secondary update: I also ordered some of a different DRAM chip to try out and the results are interesting. These other chips are 8k refresh, 13x9 row and column arrangement, self...

Pogo pin tester assembly is in progress, might be able to start testing some boards with it on Monday.

https://github.com/androda/F4_BlueSCSI/releases/tag/1.1-2022-09-20 Thanks to @jokker we now have CD/DVD image support in a full release! This release also improves Atari support, among other things. See the release notes. This brings F4 up to date with the upstream release v1.1-20220917.

At a guess, this is a rebadged SCSI controller chip plus microcontroller. Having the ROM dumped is a step toward figuring out which architecture the CPU is.

Also, a status update. I have redesigned my "downstream" tester board a bit, and hope to have the updated version by the end of next week. This will be set up with pogo pins as a fixture for use in starting production of these hybrid recreation boards. The pogo pin tester will allow me to run...

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
