The ZIP file of test programs for the VGA3 board contains one new test program for the Z80/Z180 machines: vga3tty.com. This is the TTY key mapping which is used in the UNA and RomWBW BIOS's.

UNA alpha release 3.0 of 24-Jul-2017 includes VGA3 support. On the MarkIV, I am running @36mhz, 1 memory w.s., 4 I/O w.s. Wayne has previously released RomWBW 2.8 with VGA3 console support.

============================================================ ===========
Just a note to VGA3 builders: do the testing with the UART as your console BEFORE installing any VGA3 enabled BIOS. This includes both video and keyboard testing.

UNA for the VGA3 is now in BETA release. See the software / firmwareos / una / binary page for binary & source updates.

A colorful sign-on screen, attribute & cursor setting BIOS calls, and BIOS documentation (una-bios.txt) are all updated.
