Last on had safety-earth, this didn't have such luxuries, but there are no metal parts much to be earthed either, so 230v socket was euro-style, 2-pin.
Power boards transformer has much more windings, and ffiltering caps are same brand as earlier, also, fuses of course. control board has 74 family logics, motor control IC:s, couple memories and cpu's of some sort, lockable mini-ide connectors, power resistors and discrete components. PCB at ink cassette assembly has bunch of connectors, opto-coupler plus power resistors & lockable mini-ide connector. Couple more opto-couplers were found at ink cassette too, and paper roll has one too. Again, solenoid took care of letter-punching.
Keyboard has couple IC:s, 74 family, and 5451 led display driver, plus discrete components.
