Some you need to add a space, as in "4 k" as "4k" sounds different. Talking old kit here, but still used. Heck, even Stephen Hawkins used an old voice kit audio interface, whilst the front end got many upgrades, he stuck with the old texas voice chip affair as people ended up associating it with him. He had a choice of upgrading, BT even reproduced a synthesis of his original voice that could be used, but he stuck with what worked well for him for years. Some people, don't have those choices though. But then legacy tech is and always will be a PITA support wise, in any field of development.
