I have updated the My4TH ROM to v1.3. ROM v1.2 still had bugs in the words EVALUATE and BLOAD.
|
|
2023-06-17 |
My4TH now supports floating point arithmetic. To use floating point numbers on My4TH,
you need to update your ROM to v1.2 and copy the m4-float binary module to your EEPROM memory.

Budgetronics now also offers a
Forth Deck keyboard kit.
|
|
2023-05-23 |
The My4TH computer got a keyboard and a display. Built into a 3D printed case, I call the computer
"Forth Deck".

I have released the new ROM v1.1 for My4TH. I fixed a bug in the ROUT word that made it unusable in v1.0.
|
|
2023-04-12 |
The My4TH kits are available now! You can buy them at
Budgetronics.
A kit costs 49.95 € and the EPROM included in the kit is of course pre-programmed.

Today I proudly present my new hombrew computer, which I call My4TH.
My4TH is the successor of MyNOR and is a Forth system.
The implemented FORTH follows the
Forth 2012 standard as closely as possible.

I have fixed a really bad bug in the floating point routines of the My4TH light ROM.
If you have built a My4TH light and want to use the floating point words, you need to update
to the latest ROM v1.1.
|
|
2023-12-08 |
Two new versions of the My4TH computer are now available:
My4TH XS is a very simple Forth computer with only 14 ICs.
My4TH light has one more IC and has a very fast I2C bus.

Big My4TH firmware update: v1.4 of the ROM adds some nice features to My4TH
(release notes).
I also made a special ROM version for people who do not use the board with a Forth Deck. The
"nfd" version of the ROM compiles and executes Forth code much faster,
it has a faster I2C bus and a better text editor.
Click to download it now.

I have made a video about My4TH and the Forth Deck.
In the video I describe how the My4TH computer works.

I have written a Forth system for MyNOR and TraNOR. Are you interested in a very old programming language?

Hi all, I have finished my transistor version of MyNOR: TraNOR uses 2495 transistors!

BudgeTronics
is now selling all the boards as kits, including the new
VFD Board.
An important note: I do not make any money with the kits. According to the
CC License,
anyone may assemble and sell kits.

I have written a new game for MyNOR: Pac-Bam! is like Pac-Man on LCD.
|

The LCD extension board kit is now also available at
BudgeTronics.
|

BudgeTronics
is now selling the MyNOR base kit and the calculator extension kit.
The LCD extension kit will follow soon.
I have also released two new games for MyNOR with the LCD extension: A Breakout clone called Briksout and a kind of "master mind" game
(thank you Joachim for your contribution!)

I have made a new extension board for MyNOR: The VFD Board with a vacuum tube display.
I have also updated the tools "mynor" and "myca", and I updated the ROM and the
API specification to version 1.2.

You will soon be able to buy MyNOR kits at BudgeTronics.
Hopefully the kits will be available at the beginning of February 2021.

Joachim found another bug. The api.hsm file shipped with the MyCA cross assembler is broken. Please update MyCA to
the latest version 1.09c.

Joachim Leßmann found a small mistake in the documentation and the schematics of MyNOR. The EEPROM had a wrong
part number. It is a 64kB EEPROM with the correct part number 24LC512. If you bought the 32kB version 24LC256,
make sure that you do not use the program memory locations 5 through 8 because this would overwrite the locations 1 through 4.
Thanks Joachim for reporting this mistake!
