Franz, what hap posted is fine, it will do the same thing.
(Just copy that 64-bytes-table from ROM 0880-08bf to RAM 2bc0-2bff.)
In the new eprom I put it at ECC0, but that will be 'mirrored' at 2XC0-2XFF..

The other bit in the first version I removed wasn't a computed goto as I thought, but would be used for the display and was correct (FE instead of FD).
But it isn't called at all, so doesn't hurt.
