Building a ZX Spectrum from all new parts #ZXSpectrum #VintageComputing @lostretrotapes
Lost Retro Tapes documents building a new ZX Spectrum retro computer from all new parts:
This series of posts will be documenting my quest to building a ZX Spectrum using as many still available parts as possible, I am not sure yet if it’s completely possible, but due to the work of people like Charlie Ingley who created a brand new replacement ULA chip, I am feeling confident.
I was going to redraw the board and get it printed, however my initial research alerted me to these reproduction Issue 3B boards available on PCBWay from PABB – the Issue 3B board was the most common board for the 48k Spectrum, and is a good place to start.
I ordered the boards (well 5 of them due to minimum order quantities) and started looking at what resistors, diodes, crystals, transistors and capacitors from the original schematics, using a list from here, I could still get from suppliers such as Farnell. I have reproduced my findings here in a table I will keep updated.
See the video below and the complete series written up in the thorough guide here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
