Hi, All, This has all been discussed over on the cbm-hackers list over the past several months, but I've been fixing a couple of Static PET boards for someone in Japan. The only thing that appears to be unique to one of the boards is a 2316B in a Commodore-built 6540 adapter board (P/N 320076) and the 901447-12 ROM that's in it. There is no corresponding ROM image on Zimmers.net (where the old funet archive lives), and this ROM reads all zeros. I have a photo of the keyboard layout for a Japanese chicklet PET, and it doesn't happen to match the map of the Japanese C-64. One interesting feature is a few Kanji characters mixed in with the Katana, specifically, "4" maps to the Kanji for "year", "5" has "month", and "6" has "day" - obviously for rendering dates easily. There looks to be 51 Japanese glyphs total (all the Katakana characters, the three Kanji, and a couple of other characters needed to write sentences in Japanese). Given that the editor ROM is identical to a standard European/US BASIC 1.0 PET, it seems likely that the character drawn on the key would be the replacement in "upper/lower case mode" for that particular symbol. It seems likely I could reproduce the general contents of the ROM following the keyboard map, but it would be great it someone out there happened to have the real thing. I already know that nobody on the cbm-hackers list has come forward with a copy, but I'm pretty sure there are PET owners on this list who are not on cbm-hackers. If anyone happens to have this ROM or ROM image, please share it with the great repository at Zimmers.net. Thank you, -ethan --------------------------------Reply: ---------------------------------------------------------- It would certainly be nice to find the 'official' ROM, but I thought that the ROM that Philip (the owner of that PET on your bench) created was pretty well complete and correct; it seems to match my Japanese keyboard perfectly except for one character, and I suspect it's the key that's wrong and not the CG. Did you try that image and match it up to your Japanese chiclet keyboard? I've been playing with the idea of having all three (four?) character sets available on screen at the same time, using the reverse video signal. mike
