Commodore Modem Model 8010

Commodore Modem Model 8010

autopsy:

This is my first Modem, this is a Acoustic coupler modem for Commodore PET but i could use it with a IEEE488 Interface for the Commodore 64.

The Commodore’s 8010 Modem is an IEEE-488 (1978 standard) device which communicates via any standard telephone.

The 8010 Modem meets Bell 103 standards for communication at a fixed rate of  00 BAUD. The telephone interface is acoustic so the modem is portable. This means Commodore computers can communicate with, large computer systems like The Source and MICRONET, and other small computers.

Initially Commodore supplied software will support the following applications, with many more to come.

1) Terminal emulation.
2) Disk file send and receive.
3) Wordpro 3 sequential file send.
4) Hardcopy using Commodore printers.
5) Disk spooling.

A switchable four-section bandpass filter provides out-of-band rejection assuring accurate processing of the input from received carrier, even at signal levels of less than -47 dBm.

Jitter-free data is guaranteed by a soft limiter and phase lock loop discriminator. The carrier detect circuitry prevents the CBM Modem from operating when excessive noise would produce errors or cause marginal operation. This feature also assures accurate teleprocessing connections and inhibits chatter when the received signal fades.

    Hi

    I’ve got the same hardware somewhere but I never had been able to make any use of it. As you pictured it’s documentation, could you make a scan of it and publish it on your site (or send me it by mail). Could you describe how you’ve using it on your C64 ?

    Thanks in advance.

    Hi Hervé, yes, i have the documentations but i don’t have the scanner ;-D about this modem, i have used it over 23 years ago with a C64 and a IEEE488 Interface.

    I had one of those when I lived in Germany, and I actually ran a BBS off it, the handset was permanently strapped into the coupler and a magnetic coil stuck to the phone / user port which also controlled a motorized lever to take the phone on/off hook. A hilarious setup, when I think about it now. ANYWAYS, I now have it without power supply. Do you have any info on the power supply pinout ?
