Although everything is documented on how to make your own on Eric Pearson’s MIB238 GitHub project page at https://github.com/epearsoe/MIB238
, I’m offering a small run of these for those that don’t have the skills to build their own. These are fairly expensive to build because of build and test times, sourcing an obsolete part, and a few other specialty parts that aren’t cheap.
I’m going to approach this the same way the original MIB cards were sold, with the MIB238-WiFi card and cables sold separately so you can configure it the way you want to keep the cost down from needing unnecessary cables. This new version removes the serial port connector and replaces it with an integrated WiFi modem for up to 19.2k baud. It also has a terminal port for external 80 column support, parallel port for printer, boot PROM socket, and supplies a memory expander signal for memory expander cards over 64K.
Unlike the older version, if you just need WiFi modem, boot PROM, and expander signal, then there is no need for an external cable coming out of the console. This version saves on the cost of a serial ribbon cable, external modem/WiFi modem, and external power supply.
