BBC Model B + MMFS: Command Guide

Image
BBC Model B + MMFS: Complete Command Guide for SD Card Systems If you’ve upgraded your BBC Model B with the MMFS SD-card interface , you’ve opened up a whole new way to use your retro computer. No more fragile floppy disks MMFS lets you browse, load, and run hundreds of disk images (.SSD or .MMB) straight from an SD card. This guide collects every useful command you’ll need to explore, manage, and boot software quickly on your setup. Quick Start — Create & Use Your Own MMFS Disk Here’s a simple first project to prove everything’s working. Goal: Create a blank disk, format it, write a BASIC program that prints “Hello, World!”, save it, and run it again. You can watch my YouTube video below and see the guides below for more commands. Create or Select a Blank Disk Slot Insert your SD card and power on. To check what’s available: *DCAT Then choose an empty slot (for example, disk 100): *DIN 0 100 This mounts disk 100 into drive 0 (your working drive). Format the Disk ...

BBC Model B – Installing Turbo MMFS

Image
BBC Model B – Installing Turbo MMFS One of the easiest and most useful upgrades you can make to your BBC Model B is installing Turbo MMFS . It replaces old tape or floppy drives with fast, modern SD card storage making loading software instant and much easier. You can also add more software by updating what is stored on the SD Card. I bought a pre-burnt Turbo MMFS ROM and ready-made SD card interface , so installation was plug-and-play, this was also cheaper and less time consuming as you will see. Here’s exactly how to fit it and get up and running.  What Is Turbo MMFS? Turbo MMFS is an enhanced version of the BBC’s MMFS (Multi-Media Filing System). It lets your Model B load programs directly from an SD card while remaining 100% compatible with classic BBC software. It feels like a small modern miracle, you power up, type a couple of commands, and programs load almost instantly. Step 1 – Install the Turbo MMFS ROM Power off and unplug your BBC Model B. Remove the ...

Op-Amp Series – Part 5: The Differential Amplifier

Image
  The Differential Amplifier A differential amplifier is an operational amplifier circuit that amplifies the difference between two input voltages . Instead of measuring a signal relative to ground, it measures how much one signal differs from another . This makes differential amplifiers incredibly useful for: Rejecting noise Comparing signals Sensor interfaces Audio and measurement circuits In simple mathematical terms: Output = (Input 1 – Input 2) × Gain In the real world, signals are often noisy. Long wires, motors, power supplies, and digital circuits can all introduce interference. A differential amplifier helps by: Amplifying only the difference between inputs Rejecting signals that appear equally on both inputs (called common-mode signals ) The Basic Differential Amplifier Circuit Differential Amplifier Circuit A classic differential amplifier uses four resistors and one op-amp. For proper operation: Resistor ratios must match This ensures accurate subtract...
