A stack-counter acceptor is a stack acceptor in which the storage alphabet is just one letter. The present paper discusses multi-stack-counter acceptors operating in quasirealtime, i.e., acceptors in which each storage tape is a stack counter and in which there are only a bounded number of consecutive∈-moves. For each positive integerk let be the family of languages accepted byk-stack-counter acceptors (k-counter acceptors). Each is a principal AFL closed under reversal but not under∈-free substitution or under intersection. Also, and a specific language in each, is exhibited. For each and there are noi andj such that. It is shown that a quasi-real-timek-stackcounter acceptor is equivalent to one operating in non-deterministic real time. Lastly, it is shown that acceptance by final state of ak-stack-counter acceptor is equivalent to acceptance by empty tape and final state.
