GILLMANN%USC-ISIB@sri-unix.UUCP (12/22/83)
From: Dick Gillmann <GILLMANN@USC-ISIB> Having tried to port a terminal emulator to the Hyperion (and not having much luck), I feel I should warn you about it. It is NOT PC compatible, and the Compaq basically is. When I took the Hyperion apart, I found that it is much different from a PC. It uses a different UART. There is no 8087 slot. It even has a Z80 in it for some reason. But the biggest problem with the Hyperion is the lack of documentation. There is no equivalent of the Tech. Ref. Manual, or even a list of DOS calls. You're pretty much stuck with using software sold by Hyperion and a few selected vendors, although the generic MSDOS stuff like compilers will work. Dick -------
