Hey, I resent that! I built my own 300 baud modem from parts I got from a dumpster, more or less guessing my way through the circuit for lack of documentatino. It worked, it had lots of blinking LEDs, a sturdy plywood box with a mass of switches which made it look like an ICBM launch console but it did get me online with my Commodore-64. Initially I had to dial by hand using a rotary phone, later I made a pulse-dial circuit and program so I could do some war-dialing - at 300 baud. On a shared phone line in a student house, with one of those pulse counters which clonked loudly when another quarter was added to the phone bill. At night. Boy, did they support my late-night hobbies...
