Simmtec, Inc 32MB 72-pin 70ns FP Parity SIMM D2298A D3578A

32 MB 72-pin SIMM for legacy HP printers

This 32 MB 72-pin SIMM operates at 70 ns with fast-page parity and is identified by part numbers D2298A and D3578A. It is designed as a memory upgrade for compatible HP LaserJet and DesignJet printers. The module is supplied new and carries a lifetime replacement warranty from the supplier. It addresses the need for expanded memory in older HP output devices that accept this form factor.

Sustained operation in compatible printers

Under continuous print workloads the module delivers stable data access at its rated 70 ns timing without thermal throttling or timing drift. Parity checking provides error detection during extended print jobs, helping to prevent data corruption across long runs. The fast-page architecture supports repeated page accesses typical of rasterised page streams. Printers requiring larger memory capacities or newer memory standards cannot use this module.
