Thanks for all the hard work.

I've been trying it out with a Macbook Air M1 and noticed some bugs. I've
just filled a bug report in:


detailing it, but basically the FTLK UI is invisible on macOS Big Sur with
an M1-based mac.

> Hi peeps,
> Einstein 2020.4.13 adds PCMCIA Flash Card support to Einstein. New Flash
> Cards can be generated and managed using the Settings panel, and can be
> added to a list of available PC Cards.
> It is possible to download PC Cards from a physical device and add them
> to Einstein, but the process is tedious, and not all FLash cards may be
> supported.
> No ROM Cards yet.
> Insert or eject a Flash Card by clicking on the upper or lower half of
> the PC Card button. The pulldown menu lists all available cards. Cards
> can be marked the remain inserted through Einstein restarts.
> ::::
>   - The Network code should work much better now, but incoming TCP/IP
> connections are still not supported.
>   - Support for the French Watson ROM.
>   - Fixed sound on Windows (was only in the left speaker).
>   - Copying text to the Newton Clipboard (long tap, drag to the top
> left) now also copies the text to the hot clipboard (use Ctrl-V to
> paste), MP2x00 US version only.
> ::::
> This version of Einstein merges my changes over an entire year back into
> Paul's code. This is great, because all new features written by Paul are
> now also available on the FLTK version. Besides insider features and bug
> fixes, there is now support for the Watson ROM!
> But this also has a great risk. Merging always introduces bugs, no
> matter how careful developers are. Please backup your Flash RAM files
> and whatever else you feel is important. Please verify that the Network
> is working well, and serial port emulation still works for you, and alll
> other features that you regularly use.
> ::::
> Einstein 2020.4.13 is now available in four version on
> http://messagepad.org/Newton_Installs.html

> You can find FLTK based version for the desktop systems, and a new/old
> "native" version for MacOS. The native version does not use FLTK for the
> user interface and hence misses more complex UI stuff like PCMCIA Linear
> Flash Card support and the Toolbox, but uses the original user interface
> that Paul developed. Internally, the emulators all identical!
> The iOS version will need a few corrections, and if someone would like
> to try to get it to work, I will happily publish the build instructions
> on GitHub and MessagePad.org .
> The Android version is next on my Todo list. There is a good chance you
> will be able to download a new version in a week or two.
> I have not tested building on RaspberryPi yet, but there is no
> fundamental reason for it not to work.
> I have not tried to build the MacOS M1 version yet (well, I don't have a
> machine to test it on anyway), but I'll happily add that feature if
> anyone wants to try it.
> Both platforms, MacOS/M1 and RasPi, use a superset of the Newton CPU
> command set. Many Android devices do too. If someone is brave enough,
> the JIT emulator has been prepared for this case and a specialized JIT
> emulator could be written for Einstein on ARM CPUs that should run
> probably twice as fast.
