Does anyone know which SCSI and ethernet controller chips are used in the new DEC & ISC boxes and/or how they compare to the throughput of the NCR 50C90 (SCSI) and custom ethernet support of the NeXT machine? lance Lance Berc lance@orc.olivetti.com Beer as an alternate Olivetti Research Center lance%orc.uucp@unix.sri.com currency!

One of the DMA channels of the NEC V50 (80186 compatible) services the Adaptec SCSI controller. I would still like to know about the DECstation 3100 hardware. I appreciate the discussion on UNIX implementation that the original request fostered, but my interests at present are in the physical (not metaphysical!) aspects of the new DEC entry, i.e. footprint, basic system components, i.e. cache sizes, and peripherals (internal or external). Has anyone other than DEC personnel seen or used the DECstation 3100? seenu ..!pyramid!isieng!seenu #include <standard.disclaimer>

Has anyone other than DEC personnel seen or used the >DECstation 3100? It uses the same box as the VAXstation 3100, 10.33 cm (4.07") high by 46.38 cm (18.26") wide, by 39.42 cm (15.52) deep. 64K I cache, 64k D cache. Space for an internal 3.5" hard disk. It uses an industry standard chip for electrical interfacing to SCSI, and a DEC internal chip for doing the SCSI work, good to around 4mbytes/second. Internal disk can be RZ23, 105mb formatted, or external RZ55, 332mb formatted. Also takes TK50Z 95MB tape in external box. 8mb main memory comes standard; potentially upgradable in 4mb increments. Both thin and thick wire ethernet connectors provided, with switch to select which is active. I don't remember which ethernet chip is being used off hand, though I think it is the Lance. Max power consumption is 122 W. weight 9.47kg ( 20.14lb). diskless. 1 bit mono display, or 8 bit color display, 1024x864 resolution. <The usual disclaimers here>
