How does the 3B1 differ from the 7300? Where can I receive information on availability and price (this seems to be a perennial problem with AT&T products--last time I called my local AT&T office for 3B info, I got their personnel department...) Also, I recently received information on their 32100 and 32200 microprocessors. Does AT&T sell a packaged system using either of these? How do they compare with, say, a 68000 running at comparable speeds? -- /Steve Dyer dyer@harvard.harvard.edu harvard!dyer

The 3B1 is a 7300 with a large disk (40 or 67 Meg) and the MS-DOS add-on board (some vaariation on 8086 with 512K and good OS support for interfaces to peripherals). Because the disk is full-height, the case is a shade taller. It can supposedly hold more memory, but this may just mean "We're also announcing a new memory board"; I can't tell from the price list in our stockroom and I haven't seen the glossy marketing literature. >Also, I recently received information >on their 32100 and 32200 microprocessors.

Well, the 3B2/310 and 3B2/400 are both 32100 based (the 3B2/300 uses the 32000, which is the predecessor series). The 3B5 was 32000 based; the 3B15 is the same IO system (mostly) with a 14 MHz 32100. We also just announced a VMEbus single board computer, with the 32100 CPU, 32106 Floating point chip, 1 Meg memory, control&glue chips (the product line includes some nice memory control chips). We probably also have some other packaged systems. I'm don't do hardware, so the rest of the info I give you will be vague and inaccurate :-) The 32000, 32100, and 32200 series chips are full 32-bit, unlike the 16/32 68000. If you build an "equivalent quality" machine around a 68020 and a 32100, they're of similar speed; I don't know enough to be more precise. The 32100 is available at 14 and 18 MHz; some products use it at 10 MHz. I didn't realize we'd announced the 32200; all I know about it is that it's "real fast". Disclaimer: I'm speaking on my own, rather than on behalf of AT&T. Most of this is probably accurate, but any corrections will be appreciated. -- # Bill Stewart, AT&T Bell Labs 2G-202, Holmdel NJ 1-201-949-0705 ihnp4!ho95c!wcs
