About the MSX-IDE 2021 PCB

MSX-IDE 2021 is an open source PCB design by jabadiagm, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 55.3 × 64.8 mm, with 15 components from 9 distinct parts.

Other key parts include the 74HCT373, 74LVC245, 74HC245 and Tang_Nano_20k. By type, the board carries 6 ICs, 6 capacitors, 1 connector, 1 diode and 1 resistor.

It belongs with the retro computing designs in this gallery.

From the project

MSX Goa'uld board with Tang Nano 20k

MSX2+ engine in Z80 socket. It turns one MSX into an MSX2+ by replacing Z80 processor. FPGA in board contains: Z80 V9958 with hdmi output MSX2+ BIOS 4MB mapper RTC PSG through hdmi OPLL through hdmi SCC (audio only) through hdmi

There are two lines of boards, 1.4 (by Palver, DIP & SMD) and 4.1 (by Chandler, SMD). Main difference is the orientation of the hdmi connector, to the same side of Z80's pin 1 (4.1) or the opposite (1.4). Revisions 2, 3, 4 are outdated and kept for reference only.
