The Forth Deck mini  is a housed version of the My4TH computer board with an additional keyboard and display. A built-in rechargeable battery makes it portable and independent of mains power.

With this computer you can write and debug your own Forth programs directly on the deck, no need for a serial terminal or PC! It’s a bit like the home computers of the 70s and 80s with their built-in BASIC interpreters.

The Forth Deck has all the My4TH features and a few more:

• 40 x 4 character LCD
• 56 buttons QWERTY keyboard
• 6.6 Wh LiPo battery
• 6 hours runtime without recharging
• 8-bit discrete CMOS logic CPU
• 8 to 14 MHz clock frequency
• 32 KB ROM, 32 KB RAM, up to 256 KB EEPROM
• 17 CMOS logic chips of the 74 series, 3 transistors
• RS-232 with 4800 baud
• I2C-bus for extensions
• 16-bit Forth 2012 system
• Size 198 x 118 x 35 mm

There is space for an Adafruit PCF8523 Real-time clock module or other STEMMA QT I2C board.
