A handheld computer with a self-contained keyboard and display that you can program in Lisp.

sudo apt install arduino-core-avr gcc-avr avrdude
The booloader is from https://github.com/mcudude/MightyCore commit
You can override
AVRDUDE_OPTS on the
line if you have another programmer.
This method assumes the bootloader has already been installed.
MONITOR_PORT on the
make command line if autodetection of
the tty device fails.
This method can be useful for flashing uLisp if you want to reuse the usbasp for programming the payload, e.g., if you do not have a serial programmer like the Sparkfun one.
Beware though that this method overwrites the bootloader; i.e., it writes uLisp to the board such that uLisp will be run directly after power on.
Without the bootloader to talk to, avrdude won't work, so e.g. issuing:
will result in this error condition:
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00 [...]
To make serial programming work again, you have to reflash the bootloader.
Tested on Debian GNU/Linux ppc64le (aka ppc64el) bullseye/sid, with package versions:
|gcc-avr (provides avr-gcc)||5.4.0||1:5.4.0+Atmel3.6.2-2|
