Back to the Amiga – Pt. 1

Well with Retro being the new thing I thought it was time to get my Amiga 1200 singing and dancing again and also document all the things I’ve done to make it work.

For a start the amount of things they have improved on the Amiga scene since 1999 has peaked my interest up again.

If you don’t know what the Amiga is the Wiki page here goes through the lot :

I will publish various Parts to this series when I get time to write about them, but to start you off this is Part 1 which shows you what you require to get your Amiga to output to VGA

What do you require to start?

First you will need a Commodore Amiga A1200

If you just want to use the system to play games from Disk and want to use this with a VGA monitor you only require the following extra equipment:

GBS8200 CGA/EGA/VGA converter – This can convert the Amiga’s RBG output and to work on VGA out.
A 680 ohm resistor to create this lead and Heat-shrink to make it neat.
Amiga DB23 to VGA Adapter to pull apart for the lead to the GBS8200
Optional but Recommended : Wemos D1 Mini Pro ESP8266 – This allows you to make the GBS8200 better by using the application GBS Control
On how to build the hardware for GBS Control the instructions can be found on there Wiki –

GBS8200 Setup for Video Output to VGA

Creating the DB23 to GBS Lead – the GBS8200 comes with a lead which can be soldered straight to a the pins of the DB23 connector – the Wiring diagram below shows you which wires need to be connected – Yellow and Brown are not used in this setup and can be removed by pressing in to the rectangle tab and pulling the wire out.


The 680 ohm resistor is soldered inline on the grey wire and heat-shrink is applied to keep it protected

GBS8200 + ESP8266 (Optional but recommended)

If you build the optional GBS Control unit, the ESP8266 joins on to the GBS8200 like the following pictures and gives you finer control (via. a webpage) and better picture output whilst using the GBS8200
