Hello Arild,
I wonder if part CD8011ANL, CD2354NL from TI are house number
because I have a computer card with those kind of p/numbers which
could be memory (prom) chips.

Could be.
I finally got through to Texas Instruments and got a reply where they
told me they couldn't be of any help as they no longer had any access
to information regarding those (discontinued) products.
But I've picked up a little information here and there, enough to know
that the TMC-0281 is a speech-synthesis chip.
One of the two other ICs is indeed a ROM chip, though I'm not sure
which one.

Any ideas where I can go to get information and pinouts?

Try to locate the data and address buses. These should be relatively
obvious. Then look for a crystal, a reset pin, supply rail, ground.
With any luck the pinouts will be similar to a standard product.

FWIW, searching for 8011 at datasheetarchive brings up numbers such as
"7801102RA" whose data*** is that of a 20-pin 74373 or 74374 octal
D-type latch/flip-flop.
