I couldn't find it, but thanks for sending me a replacement. I've done a quick comparison with a 3.0 ROM, and here are the differences: ROM 0: 000F: 1E 23 ; version number 3.0 -> 3.5 0F89: D7 00 ; replace the RST 16 that prints the startup � with a NOP ROM 1: 35DD: 20 57 ; -> W 35DE: 20 45 ; -> E 35DF: 20 53 ; -> S 35E0: 4D 54 ; M -> T 35E1: 49 20 ; I -> 35E2: 4C 43 ; L -> C 35E3: 45 4F ; E -> O 35E4: 53 41 ; S -> A 35E5: 20 53 ; -> S 35E6: 47 54 ; G -> T 35E7: 4F 20 ; O -> 35E8: 52 43 ; R -> C 35E9: 44 4F ; D -> O 35EA: 4F 4D ; O -> M 35EB: 4E 50 ; N -> P 35EC: 20 55 ; -> U 35EF: 43 52 ; C -> R 35F0: 48 53 ; H -> S 35F1: 4E 20 ; N -> 35F2: 4F 4C ; O -> L 35F3: 4C 74 ; L -> T 35F4: 4F 64 ; O -> D 35F5: 47 2E ; G -> . 35F6: 59 20 ; Y -> 35F7: 20 7F ; -> (c) 35F8: 50 20 ; P -> 35F9: 4C 31 ; L -> 1 35FA: 43 39 ; C -> 9 35FB: 20 39 ; -> 9 35FC: 20 34 ; -> 4 3600: 20 53 ; -> S 3601: 20 41 ; -> A 3602: 7F 4D ;(c)-> M 3604: 31 42 ; 1 -> B 3605: 39 41 ; 9 -> A 3606: 39 53 ; 9 -> S 3607: 30 49 ; 9 -> I 3608: 20 43 ; -> C 360A: 53 52 ; S -> R 360B: 41 4F ; A -> O 360C: 4D 4D ; M -> M 360E: 43 33 ; C -> 3 360F: 6F 2E ; o -> . 3610: 75 35 ; u -> 5 3611: F0 A0 ; p -> (+80) 3818: EB E3 ; k -> c (+80) so "Missing disk" becomes "Missing disc"!!
