Here are some hi-res photos of the Commodore 232 and Commodore 264 prototypes. The C-232 and C-264 were two1<\/a><\/sup> of the planned models of the TED series, but neither shipped. The C-264 became the Plus\/4, with productivity software preinstalled in ROM, and the low-lost C-232 was replaced by the even lower-cost C16 and C116 models.<\/p>\n

The Photos<\/h2>\n

Here is what they look like:<\/p>\n

The sticker on the bottom of this C-232 carries a serial number of “AA5 00006”.<\/p>\n

\"\"<\/a><\/p>\n

And this C-264 has a sticker that says “SAMPLE”:<\/p>\n

\"\"<\/a><\/p>\n

The C-232 is missing the user port:<\/p>\n

\"\"<\/a><\/p>\n

But the C-264 connectors on the back are the same as the Plus\/4’s:<\/p>\n

\"\"<\/a><\/p>\n

The C-232 board (ASSY NO 250439, PCB NO 251728REV3) is missing the ACIA for the RS232 port (like the C16\/C116), but has two sockets for the optional function ROM chips (16 KB each). On the Plus\/4, the function ROM contained the “3-plus-1” productivity software. Note the heatsink on the TED chip, which Commodore should have installed on all TED-series machines.<\/p>\n

\"\"<\/a><\/p>\n

The board of the C-264 is basically a Plus\/4 board. It carries the same ASSY NO 310163. It too is missing the function ROM chips.<\/p>\n

The ROM Contents<\/h2>\n

The ROM chips contain the same data on both machines:<\/p>\n
