I can't find the HCL doc, but according to the files present on the CD it runs on: IBM 6040 (ThinkPad 820) IBM 6042 (ThinkPad 850) IBM 6015 (PowerSeries 440, 7020-40P) IBM 6050 (PowerSeries 830, 7248-43P) IBM 6070 (PowerSeries 850, 7248-43P) IBM 7248 (43P-100, 43P-120, 43P-132) Motorola PowerStack Series DT/E/MT The 7248-43P is substantially different from a 7043-140 "43P". I have it running on a PowerStack Series E. Did anyone ever unearth the Sun compiler for that? floppy by dd'ing the image using a SPARCstation (running NetBSD).
