This is a replacement for a grundy newbrain power supply. You connect a 12v (2A or more) and it provides the necessary voltages for the newbrain +5v, 12V, -12V. I tested it and it works. I am now printing a case for this you can find it here. You should also make a cable and…
New Rom for my Modular Newbrain supporting also the graphics screen up to 640×200. There are 16 colors which are indexed so they can easily changed. Currently this works on the emulator but it will work on the Hardware after i update the FPGA. The command is OS GCOL <Fore>,<Back> i.e. OS GCOL 2,15 sets…
I am currently working on adding color to my newbrain modular computer. Currently only the text screen is supported but hopefully it will also support the Narrow Low Resolution graphics screen (256X240 resolution). Technical info I am using an extra 32K(4 pages) to save the color info. I added a new command to Basic “OS…
Code produced by GEMINI AI after a not very long conversation, imported to Newbrain Emulator using the Tools–>Import from textfile feature, and Run with Newbrain Cpu at 16MHz (Tools–>Set Cpu Multiplier=5). Original Code here Hi Res option This code let the user choose the graphics resolution
