This is a new storage device with fewer components and using an arduino NANO instead of an Arduino UNO. You will also need the following modules: Also some 3mm spacers for the LCD (4) and for the board (4). Bill of materials: All Modules should be soldered on the PCB, no female connectors to save…
This is the final board that i will order from JLCPCB. Hopefully it will work. All except the connectors and the 10μF catalytic capacitor will be assembled with a total cost including shipping of 150€ for 5 boards. Gerber ,BOM and pick and place:
I am currently developing a single board computer(SBC) z80 Hardware Computer emulator and it is almost complete. Hopefully it would be possible to emulate any z80 home computer. I am currently working on the FPGA implementing several components and see if the hardware needs any alterations. Specification Cpu Z84C0020FEC FPGA Sipeed TANG 25K Video HDMI…
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
