If this is the (compared to other MOS ICs) rather flat case with the angled sides and grey lettering, then, as far as I know, it was made, or at least packaged by GI (General Instrument) in Taiwan. > Looks like they made a production run of the > localized Kernal rom, after having made the deal.

Yes, the Kernal ROM (and the TED for other PAL variants in south america (*)) is the only location specific IC in the 264 series. They also made the 318004-04 until late 1984 and only then switched to the bug fixed 318004-05. You can sometimes find a C16 with all ICs from 1984 except the 318004-05 with a 1986 datecode. (*) There is a picture of a 8365 up on plus4world.com. There is also supposed to be a 8366, but I haven't seen it yet. In my C16s I have replaced the ROMs with properly programmed 27C128. Saves about 100mA in power, together with using a better power supply that keeps the system a few watts cooler without any irreversible changes. The original ROMs have been kept of course. >> That's why I still like the C16 (with 64K of course).
