This is a NABU PC booting off of an HxC2001 SD version device that simulates a floppy drive. It uses the NABU_LEO2.hfe file I've posted here: https://vintagecomputer.ca/files/Nabu/disk_images/NABU_LEO2.hfe Ongoing discussion of imaging NABU disks for use by NABU users via the NABU Floppy Drive Reproduction Project or a MAME version of the NABU computer is happening here: https://forum.vcfed.org/index.php?threads/bad-disk-image.1240644/ Note: This is probably only of interested to certain individuals on the VCF forum but I thought I would post so other can see the behind-the-scenes work being done.
