Commodore 64 Web-it, it's an embedded PC branded as Commodore 64, released in 1998 as an "Internet terminal" with embedded Windows 3.x and CCS64 emulator.
Unfortunately someone put a wrong type of RAM to it before. As a consequence, encoder and ROMs blown. Bad, bad, 16MB of ROMs!
Generally, a very poorly made machine. The worst components as for 1998. The cheapest electrolytic capacitors. Samsung floppy drive, this one with head actuator pressed from sheet metal (very prone to alignment problems). I pulled two (!) bent floppy covers from the drive. Straightened the actuator and finally aligned it. Tested in PC, works.
The RAM originally has been modified, probably to exclude bad part of chips??? (or ground some control line?).
The ROM sockets for two Amiga-like ROMs have been replaced with ROM board with 16MB of 27- OTP ROMs in SMD casings (4x27C3202). Someone who designed this board has never seen the real mainboard and the board was too high. So they "elevated" it by using leftovers from IC sockets cutting. Two of them one in the other.
The touchpad was serial, but not working. I finally found that they soldered the through-hole ceramic oscillator in place of SMD crystal, and this connection got broken. After resoldering and correcting bad GND connection it was possible to make it react on serial port.
I decided that it will be better to not touch the membrane keyboard because it gives some readings on the ohmmeter despite looking like it's going to fall apart.
The only thing which does not look awful is the modem, made on a totally different PCB compound, probably German.
