The PX16C is a replica of the classic HP-16C programmers calculator. Unlike the Swiss Micros replicas DM16 and DM16L the PX16C comes a kit for self assembly which

Really Bad Programming (Javascript): Part 1 Introduction

Alright, so you are interested in learning JavaScript. Poor you, but even worse than that is that you're learning it from me. I don't know JavaScript in any shape

Programming Tip: Maybe Start Programming At The Strip Club

I started a computer science major approximately 2 years ago (I'm also double majoring in neuroscience as well). I'm going to be honest, I struggle with the programming

The HP-16C is quite a rare calculator from the HP Voyager series. It's made specifically for software developers. While most scientific calculators from the 1990

Ben Eater 6502 Kit — Day 22

The interrupt requests are meant to be shared between several advanced devices. The breadboard 65C02 computer has only one of those: The 65C22 VIA (versatile interface

Ben Eater 6502 Kit — Day 21

The 65C02 has two interrupt lines: NMI (mon maskable interrupt) and IRQ (interrupt request). It should be noted that IRQ are mend to be shared between interrupt

Ben Eater 6502 Kit — Day 20

The ordered spare parts have arrive and not a minute too late. The poor EEPROM looks pretty beaten: One leg broken off at the case Three legs broken on the opposite

Ben Eater 6502 Kit — Day 19

Up until now the computer was run either by a fairly slow 555 timer or even slower single stepping. This was possible because the WDC-65C02, unlike the R-65C02,

Ben Eater 6502 Kit — Day 18

As the programs become more complex debugging becomes more difficult at well. All you have are hex codes which you need to interpret yourself: Current Monitor output

Ben Eater 6502 Kit — Day 17

Now we have some RAM we have stack and can use subroutines to make the program more compact. I already used macros and include files so I can just rewrite the macros

Ben Eater 6502 Kit — Day 16

Ben Eater used a single SN74H00N 4×2 NAND chip as memory management unit which decoded 3 address lines (A13 … A15). This saves integrated circuits but has a few

Ben Eater 6502 Kit — Day 15

The first version of the Hello World program in bare metal 65C02 assembler was 342 bytes long. That's quite a lot for such a simple assembler program. We can certainly
