  1. Hello, I am collector of music keyboards and electronic sound toys and partly modify them into synthesizers. This is my keyboard site: http://weltenschule.de/TableHooters/index.html I bought an eprommer ("Willem PRO4 isp",had unfortunately defective transistors and other flaws I had to fix) and have started to dump EPROMs and ROMs of my keyboard collection. - Has anybody tried yet to make an emulator (similar like MAME) for old Casio keyboards? E.g. Casiotone 401 and MT-40 are controlled by an Intel MCS-48 microcontroller which ROM I successfully dumped. So at least the accompaniment section would be possible to emulate yet. Robin Whittle (firstpr.com) found out much about the Consonant-Vowel synthesis main voice sound ICs in early Casios, which would be useful to emulate them. Also the various Casio calculator emulators on the internet might be useful to understand what kinds of special CPUs Casio has used. Google patent search helped much to get an idea what is going on inside of them. Unfortunately most early main ICs seem to be rather based on general digital logics (networks of gates, counters and flipflops - like a Pong game) than a CPU (software controlled by one central code ROM) in its stricter sense. I am still working on documenting the pinouts and functions (e.g. key matrix eastereggs) of all 1980th Casio home keyboard special ICs. For this I already have examined all service manuals I could find on free websites. Unfortunately there aren't many about first generation Casios. (If you need info, e-mail me.) I also own a dead SK-200 (from eBay,someone elses circuit-bending-corpse); after disabling the auto-power-off (to make it turn on),only all lights flicker wildly and there is some bus activity (seen on CRT oscilloscope), but it makes no sound at all. Does anybody know the symptom? Is the sound CPU dead?
