This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

Date: 1982


Type: Cassette


Platform(s): TS 1000




					

				
		

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.

This is a quickload program. It is comprised of a short speed loader in normal ZX81/TS1000 format followed by the actual program in a format similar to the Spectrum and TS2068 tape format.





    

  • FC-Grph.z81 is an EightyOne emulator snapshot of the running program.
    • 




  • FC-Grph.wav has been edited to remove noise and provide more of a square wave signal.
    • 




  • FC-Grph.b81 is an EightyOne emulator text listing.
