You can easily use a PC's printer port for serial-EEPROM programming. You can use a device-programmer circuit used to program the MicroWire serial EE-PROM 93CXX (Figure 1). The circuit is so simple ...

Turn on the EMP-20 Programmer (in back). There is a power light next to the ZIF socket (Zero Insertion Force) and the ZIF’s handle should be straight up. Set the "T" switch on the shelf next to the ...

The [IMSAI Guy] has posted a follow-up video with all the details of how he programs GAL22V10 chips in the modern era. We noted that this was missing from his stepper motor project a few days ago, and ...

We all know that solderless breadboards have their limitations. All that stray capacitance can play hell with circuits, especially high-speed stuff, but they’re so darn useful that avoiding them in ...
