Emulators on HP-UX: Windows and Mac OS on PA-RISC. 🧵

To run productivity software of the 1990s on expensive technical RISC workstations, emulators for Unix system were common. There were at least four emulators for HP-UX on PA-RISC:

Macintosh Application Environment (MAE) from Apple, Softwindows and SoftPC, Wabi from Sun and Andataco Liken, which I had never heard before.

All were commercial products and emulated i486/Pentium PCs or 680x0 Macintosh, for DOS, Windows or System 6 or 7.

Macintosh Application Environment (MAE)

MAE is an emulator for Apple Mac OS on Unix systems, developed and sold by Apple. MAE 2.0 and 3.0, released in the mid-1990s, supported HP-UX and PA-RISC. It was often used to integrated technical Unix teams into Apple productivity suites.

MAE emulated a 68040LC processor with System 7.1 and System 7.5.3, for n HP-UX 9.0 or 10 versions. Apple applications were contained within their own X11 window and had full TCP/IP and Apple talk connectivity.

Softwindows and SoftPC from Insignia.

Another commercial and widely popular product was Softwindows, a PC emulator from Insignia released in the mid-1990s. SoftPC and SoftWindows emulated a x86 computer for DOS and Windows, and supported many Unix host systems, including HP-UX.

Unix and HP-UX support was included in SoftWindows 1.0, 2.0 and 4.0 which emulated DOS and Windows 3.1, 3.11 (16-bit) and Windows 95 (32-bit with many applications supported. NeXTSTEP 3.3 on RISC included SoftPC.

Wabi from Sun

Wabi was a x86 and DOS emulator from Sun for Solaris Unix. HP licensed Wabi for HP-UX between 1994 and 1997. HP Wabi 1.1, 2.0, 2.1 and 2.2 supported Windows 3.1 and 3.11 with select Windows applications with i486-like performance.

HP Wabi was included on HP-UX application CDs, the last version Wabi 2.2 (1997) was for HP-UX 10.20. Several applications were 'certified' for Wabi, mostly 16-bit productivity apps.

A planned Wabi 3.0 for 32-bit Windows 95 never materialized.

Andataco Liken

Last was Liken 2.0, a Macintosh emulator for Unix systems released in 1994 with HP-UX support. Hardware support and performance was limited and only Macintosh System 6 was emulated. Display was monochrome-only and a HP 9000 712 emulated Mac OS with the speed of a Mac IIsi.

"Liken does a reasonable job of executing, but even on a fairly well equipped UNIX host, it is very likely that a mid-range Macintosh will outperform Liken."

Very little information remains on Liken.
