Ohhh - nice big power hungry ECL based Classic 3000! Really slow compared to later PA-RISC cousins, but a nice machine. Pair this with a 2680 laser printer, a roomful of 793x washing machine size disc drives, and some 7980 reel tape drives and you had a nice 1980s HP data center. On a historic note one could argue that this was the machine that saved HP from the same fate as DEC. In the late 1970s and early 1980s HP had several competing 32-bit architectures(Wide Word, Bridge, Vision... All pre-PA-RISC), none of which won out and made it to market. When HP Labs pushed Spectrum (aka PA-RISC) we were waaaay behind DEC/VAX and IBM/S38/AS400/mainframe, and in a very difficult market position. There was talk about the lights going out for business computing line (HP3000), which was a big profit center for HP. The HP3000-64 had been released, then -68, and -70. If we had not had the -68 and -especially the -70 to give us breathing room and keep many big customers needing higher performance happy, HP could have found itself in a very unpleasant business bind. Spectrum was very successful and we made a good transition, and along with help from printers and PCs HP vaulted from a minor player to a real player in the server market. Stan Seiler might have some additional color. I was working in the RTE Lab then moved to MPE Lab on Spectrum, so never worked on MPE for Classic. My $0.02...
