I've done a separate "project page" for uTerm here.
uTerm can be mounted horizontally or vertically to the Z80-MBC2.
All the details including the 3D printed custom angled brackets .STL files are there.
uTerm is a VT100 terminal with VGA out and PS/2 keyboard with a power supply (for the Z80-MBC2 too). It has a "transparent" USB-TTL adapter connector, so you can upload firmware or load an Intel-Hex file (with iLoad) while the card is inserted. Both the "mixed" power supply scenarios (USB-TTL adapter not powered from USB but Z80-MBC2 powered and vice-versa) are managed. The video terminal is based on the ChibiTerm (https://hw-by-design.blogspot.com/2018/07/low-cost-vga-terminal-module-project.html).
