Jonos Escort
Jonos Escort
2013-09-12 Skeleton driver
2013-09-12 Skeleton driver
This computer is some sort of portable Z80-based system.
It seems there were about 6 models of Escort, mostly Z-80A based running
CP/M. However, this one appears to be an 8085-based terminal.
Haven't found any info.
There are interrupt handlers at 5.5 (0x002c) and 6.5 (0x0034).
Data presented at 5000 will appear on screen in a dumb-terminal format.
Haven't found any info.
