Morley-IAS ZX Series V8.55 replacement software (set of two EPROMS)

The Morley 796-855 is ZX Series V8.55 replacement software, supplied as a set of two EPROMs. It provides the V8.55 firmware revision for ZX Series panels, fitted as a matched pair when updating or restoring panel software.

The 796-855 is a spare part supplied as a set of EPROMs that carry the M200 850 software for the ZXSe (Zxse). Within the catalogue it appears only under the full order code 796-855-M200; the bare 796-855 reference is not listed on its own, so every detail derives from that single spare-parts line. The specific ZXSe panel models the EPROMs suit are not itemised beyond the range name, and the entry states no electrical, physical or environmental specifications and lists no standards or approvals for the item.
