The 3279-2A and 3279-#A only had 4 colors, but the others had 7. IAC, the 3279 was later than the 3277.

Those heavy toys have 3 blue switches, one for Normal/Test, one for 4 or 2 colours and lastly one which switch from A,a to A or vice versa. >From >https://secure-web.cisco.com/1fGzZb1QUP-J4BxK75cLd6eEXHrICNQAJKlH_SjHz8iE5228IiLNx5jsmXw1OtBc4cfqZLm4efeMYilKphJ7mJSoZ2-ZDQ_9Lh89Rxjxx4k6Wjhhe5gCevwAjJBRRsg2Cnvf1qw26IMV56awjKcT5s-tJ66-5qhBVPavgFB1kBw2_mVx0u__s0sjo8t3pMQEwGpX3Gxp8phTmQnplO8G-UDXJ_XymkX90Te1zvnPQnAa7Ji_YWiFTOzrGP1KK9o-VdcymK6wfR_qqCkREfOuABcFgXBBD8AzXLxyAk1VLl3Hf7e9dwt73-P08VmHKF6RZP6azo0AgfhCZDZCkAR7hdSf3BPw6jYRRaloixk-T2FTimURW284EQhqQvU2wEetdhfswhnjqQTWXYE7h1CfTEhAFXVvIAyIe4VfIHHAVlgmjrWOv0_iX1_pmBLVzGzGJ/https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FIBM_3270 > I see this note: "3270 character set" [ This set contains both lower and upper case letters ] "On the 3275 and 3277 terminals without the a text feature, lower case characters display as uppercase." Kees, are you perhaps refering to those 3275 or 3277 terminals? I am for once glad we don't have those terminals.
