The ‘Simple’ Wifi Modem it’s a deviceto connect a computer with an RS232 serial port to a telnet BBS. It does not use an analog phone line but internet through a wifi connection. Behaves like a Hayes dial-up modem, and it is designed and built for old computers; I use it with my first computer ever (still working!): a Sinclair Zx Spectrum and, being myself a retro-collector, also with a lot of other different machines.
My idea was to create a device with the same look and feel of a real modem: a lot of big, flashing, red LEDs and only a few SMD components.
Main characteristics:
- Emulation of a Hayes modem
- DB25 serial connector (optional external port)
- Uses 5v micro USB cable port for power (USB cable not included)
- LEDs for status, as in old modems
- Hardware flow control (partial implementation)
Its design is open source and you can find all the schematics and full instructions on https://github.com/8bit-bruno/WiFiModem
The software installed is a fork of Zimodem written by
Bo Zimmerman (https://github.com/bozimmerman/Zimodem).
It has just been modified to support this device.
28 Euro + Shipping (shipping from Italy, EU. International is usually 8 Euro)
