I'm fixing my HP8753A CRT geometry problems and checking SMPSP electrolytics.  I was thinking to get safety backups of roms. Does someone remember size of rom marked 1818-3554 and 1816-1618(eeprom?)? There is totally of 8 *rom:
08753-B0012
U15 Rev 1.0     1816-1618

08753-B0013
U33 Rev 1.0     1816-1618

08753-B0014
U4 Rev 1.0      1818-3554

08753-B0015
U5 Rev 1.0      1818-3554

08753-B0016
U6 Rev 1.0      1818-3554

08753-B0017
U24 Rev 1.0     1818-3554

08753-B0018
U25 Rev 1.0     1818-3554

08753-B0019
U26 Rev 1.0     1818-3554

Is there anyway to get newer firmware, without need of major hardware changes, or activating code to TDR option?
