After fixing the buffer-overflow issue in z80dma, the Altos 5 disks can now boot up for the first time. It also fixed Wavemate Bullet which would freeze when doing a DIR.
CP/M and DIAGS work now, MP/M boots from disk but freezes while setting itself up (see 2nd screenshot). Oasis doesn't do anything.
Have you asked to X1 if it isn't happy about it?
All of the passwords from the altos oasis disk were posted on http://www.vintage-computer.com in october under the Altos 5-5ad OASIS password? thread
