On eBay I saw a rare workstation keyboard Casio CTK-711EX, which looks like an even bulkier variant of the mythical CTK-1000 with additional LCD display, 232 ToneBank, 110 rhythms and 3.5'' diskette drive. May it be that this one was "the real thing" while CTK-1000 was only a cut down household variant? (See here for my info and hardware analysis of CTK-1000.) Here is a YouTube clip about the CTK-711EX: My CTK-1000 panel PCB contains a strange adapter like when the hardware was originally designed for something else. Perhaps it was the LCD based CTK-711EX. This would namely explain why the fairly complex sequencer and synth in CTK-1000 was made but not means of data storage. By the way, I found out the mysterious meaning of "IXA Sound Source". It's "Integrated Cross-Sound Architecture" (thanks Synrise for info), which IMO sounds more like an advertisement name without technical meaning and therefore likely soon was dropped by Casio. I just found the CTK-711EX service manual from 1998, and the main ICs do strongly differ (see CTK-1000 hardware analysis). Thus it is likely more the case design than technical similarity.
