Model 1330 - 9900 character buffer 10/1969 - Frederick Electronics Corp. announces an economical solid-state buffer store for 5 -unit code teleprinter signals with a storage capacity of up to 9900 characters. It is particularly suitable for operation with ARQ automatic error correction equipment, for speed conversion purposes and, in general, for replacing mechanical perforated tape storage systems. Storage of teleprinter signals is effected by plug -in delay line modules. The stored signals keep circulating in a delay line loop at 2MHz until it is their turn to be released to the output. A parallel output, stepped by an external pulse, or a stepped or free running start-stop serial output are available. The rate at the output can be as high as 120 characters per second. A meter on the front panel indicates how full the store is. Various outputs are available for auxiliary functions. Also provided is an input for remote clearing of the store. The model 1330 buffer store is designed for mounting in standard 19-in. cabinets. Frederick Electronics Corporation, P.O. Box 502, Frederick, Maryland 21701, U.S.A. |
