sx-64-paper-modelIf you like to create your own SX-64, please serialize it 😉

The exact number of SX-64 sold from 1984 to 1986, when it was discontinued, is unknown. The serial numbers of over 130 SX-64s from series GA1, GA2, GA4, GA5 and GA6, with serial numbers ranging over 49,000 for series GA1, 1,000 for GA2, 17,000 for GA4, 11,000 for GA5, and 7,000 for GA6 have been reported, see Wikipedia – Commodore SX-64

Technical information

Like the Commodore 64, except the following:

  • Built-in storage: 170 kB 5¼” floppy disk drive (internal version of the Commodore 1541)
  • Built-in display: 5″ inch (127 mm) composite color monitor (CRT)
  • Keyboard: Separate unit, connected by cord to CPU unit
  • Cartridge port: Placed on top of CPU unit, w/spring-loaded fold-in lid, cartridges inserted vertically (vs horizontally into back of C64)
  • I/O connectors:
    • Serial interface (rear)
    • Video out connector (rear)
    • User Port (rear)
    • Cartridge Port (hidden under two flaps on the top)
    • No Datassette interface
    • No RF modulator & connector
    • Non-standard 25-pin keyboard connector below right side of front panel. The connectors are similar but not identical to D-subminiature connectors and notoriously hard to find today[citation needed]
    • Standard three-prong AC power connector (vs C64 DIN plug to “power brick” PSU)
  • Power supply: Internal unit with transformer and rectifiers (vs external C64 PSU)
  • Extra features: Floppy disk storage compartment above disk drive which could be used to build in an extra floppy drive or compatible sized modem

    If you’d like to add them, I have two SX’s, serials GA1039966 and GA1000294

  2. Robert Talada says:

    I have GA1047531

  3. Kris Spencer says:

    I have GA1 018919 , March ’84. – I am curious how they started at GA6 and worked their way down to GA1. It seems the higher the GA #, the older it is. Any info on why or how that came about? Thanks Kris

  4. Del Scoville says:

    I have an SX-64 in nearly mint condition, works fine, I still play games on it, and keyboard doesn’t suffer from keys skipping. I’m located in New Mexico and the serial is GA1-000840

  5. bmacri says:

    My SX-64 is in excellent condition. I use it on occasion and store it in a dark, dust-free environment. I added some small heat sinks to all the chips known to get hot (VIC-II, SID, etc) and a fan that blows forced air over the chips. The fan is controlled via a switch that is located in the “glove box” on the upper side, thus out of view.
    The system also has JiffyDOS installed, with the toggle switch located next to the fan switch.
    Most of the time, I use a 1541Ultimate 2 with the computer and the internal drive is not really being used. It is, however, lubricated and it reads/writes correctly.

    I’m located in California and the computer serial number is GA1 016069 (March, 1984).
