Flea market findings

Just an update of my flea market visit:
well as usual, i went to flea market to test my luck. at first, nothing really caught my eye, but i did find computer PS/2 mises, both ball and analog models dirt cheap IMO, 0.5 € (50 cents) per unit!. considering what is inside of single mise; micro switches, cables, opto-components and maybe some other things, not bad find. Well i took all of 'em, total of 12 pcs. Also, i found 4w/230v fluorescent night lamb at 2€, but its lamp is broken . Inside of lamp was |/0/|| selection rocker switch, and surprisingly, control/ignition board. Board consists basic electricity stuff, mains fuse, caps and stuff. There were also couple nice details also, like NE555 timer, probably for PWM modulation of some sort, and TRIAC Motorola AC97AB.
And wirewound resistor 10w/100Ω. For now, diode on board is mystery, is it light-sensing diode? board has marking CDS on it.

I took photos from fluorescent lamp, and made schematic, if you find any shocking error at schematic, please, go ahead and tell . and sorry if schem. is hard to understand, i dont have that good software and i lack experience in reverse-engineering skills....
and for such amount of mises, i'm not going to make schematics or teardowns . i just find 0.5€/mise dirt cheap, so that's why i posted, if someone wonders why on earth i posted this.
