BASIC is quite a portable language, so let's see how easily it ports.

Life goes faster when you're older.
Mostly thanks to the 28MHz mode on this Spectrum Next and cheap video effects. #TGIF

The thing that gets me about the very, very rare occasions i switch my ZX81 on, is the speed. In my head it should be terribly slow, but when when you stick on one of the more advanced games like the 3D defender clone- it really isn't- really impressive hard and software... considering ..of course.

Doing a bit more experimenting with ZX81 #Forth multitasking on #Minstrel4th. Combined several example programs from user manual to make a real-time clock. A must-have for a personal computer in 2025! #retrogaming

New blog post - I have designed a new serial card for the Minstrel 4th and RC2014 bus. More on that next week, but first a look back at some of the things I tried before settling on this design.

Which are you more interested in?
1. Quickshot 2 joystick
2. THE PRINTER

Look at this! The colour scheme is fine, but they made The Printer (using thermal rather than spark which is sensible).

Ever wanted to know how your ZX81 ranked against a CRAY supercomputer from 1984? Assuming your eyesight is good enough, now you know.

Spread the word: November 25 is #ChuckPeddleDay — celebrating the engineer behind the legendary MOS 6502 processor, the heart of so many home computers and game consoles of the 80s. 💾🕹️

If you own a machine powered by a 6502, fire it up on that day and share a photo with the hashtag #ChuckPeddleDay
