Valhalla 2724 ROM

[jfphp]

Hello,
I am looking for a copy of the ROM and the 2 NVRAM of the Valhalla resistance standard 2724, the old black model and not the blue 2724A (ROM and NVRAM contents are different). The two NVRAM X2212 contain not only the cal data but configuration data and there is no way to a factory reset like in the 2720GS. Thank you
