I assume you meant APL.

In general you're stuck with what you get.

In principle if you found all of the necessary ROS (ROM) cards and wired a
switch or jumper to the backplane, you could convert a 5100/5110/5120 to
the other language or to dual-marked.

I need to design a 5100 language ROS card replacement, as one of the APL
language ROS chips in my 5100 model C has gone bad. It fails self-test.

There is also "executable ROS" associated with each language. The system
can't self-test that.

Naturally IBM made their own ROM chips which are neither pin nor
electrically compatible with industry standards. The backplane signals are
TTL compatible, though.

Not mine and way too far for me to go, otherwise I'd be all over it.
Looks like the BASIC only version of the Model 2.

In other news, I have some disks coming for mine (thanks Chuck!), so
should be resuming my efforts soon.
