6502 homebrew: the software toolchain

Now that the Apatco kit is working – at least the basic version (having trouble with the keyboard and display upgrade) – it’s time to mess around with writing code for it. Many people swear by the now-abandoned CC65 as their compiler/assembler of choice for 6502 homebrew computers. But I’m going with Beebasm. Although inspired by and largely aimed at… Read more »

6502 homebrew: debugging the kit #1

Okay, so it was time to deal with something that has been nagging at me for a while. I have this Apatco kit 6502 breadboard computer kit and never quite got around to finishing the basic setup. It takes a lot of wiring. I just got tired, put it in a box and shoved it in the projects cupboard. For… Read more »

Homebrew 6502: a new way to start

My Zolatron 64 homebrew 6502 computer project has stalled of late. But it is high on the list of things to restart once I get current projects out of the way. And a recent development has inspired me to look at it again. If you’ve been here before, you’ll know that my plan was to first build a kit –… Read more »

The stuff I use

      No Comments on The stuff I use

It’s always fascinating to know what kit others use. Reviews are all very well, but I’m more interested in what people work with on a day-to-day basis. So I’ve set up an account over on kit.com. I’ll be sharing lists of the equipment I actually use and like. If you see something in these lists you’ll know that: I bought… Read more »

Altair-Duino – the low-cost Altair 8800

I’ve wanted an Altair 8800 for a long time now. It’s not that you can do much with it. But it is such an important part of computing history. Famously, the January 1975 edition of Popular Electronics featured the Altair 8800. Or rather, it featured a non-working prototype. The first working machine had gone missing in the post. The magazine… Read more »

Building a 6502 computer – a place to start

We all have to start somewhere. Almost as soon as I’d decided I would build a 6502-based micro I realised that the learning curve is steep. It’s not like embarking on a new programming language where you can write a ‘Hello world’ program and go from there. When building a computer, there are many pieces that have to come together and… Read more »

Computing the ’60s – Raspberry Pi style

As soon as I heard of the PiDP I knew I would have to have one. Created by Oscar Vermeulen, whose KIM Uno kit I’d previously bought, it’s a brilliant recreation of a PDP-8/I using SIMH running on a Raspberry Pi. What’s more, it has loads of blinkenlights. So why did the kit sit in my office for eight months… Read more »
