Does anybody know if the AT&T 6300 --8086 machine can use a 8087 chip.
Also, do IBM type boards really work in it's expansion slots. tg@sfmin.UUCP (T.Glinos) (09/15/85)

> > Does anybody know if the AT&T 6300 --8086 machine can use a 8087 chip. You need an 8087-2 chip. AT&T retails them; I assume other people do too. > Also, do IBM type boards really work in it's expansion slots. Yep. You can put two types of things in the slots; stuff that uses an 8-bit bus (i.e. standard IBM-compatible boards), or stuff that uses a 16-bit bus, which can ship data twice as fast (most of these are AT&T products, but I think there are some boards not made by us or Olivetti.) I think there's a limit (3?) to the number of 16-bit slots available. For memory, you can do 3 things: 1) Use IBM-PC compatible memory. This means using the 8-bit bus, which is slow & boring. 2) Buy memory boards from AT&T, which use 64K chips. This is ok, and is the way to go if you want between 256 and 512K of memory, since it uses the 16-bit bus. (There are some application boards you can plug in that occupy part of the MS-DOS memory address space, and can't cope with 640K systems.) 3) Buy the AT&T 6300 with 128K of memory. This gives you a motherboard with 18 64K chips and 18 sockets. Buy 18 256K 150-ns memory chips and plug them in. (We sell some nice chips, or you can buy them from lots of mail-order places.) Dredge up an article posted on this newsgroup a few months ago that has the switch settings. Now you've got 640K, much cheaper than if you'd used 64K-based boards, and you haven't used up any slots. It also uses less power and generates less heat. -- ## Bill Stewart, AT&T Bell Labs, Holmdel NJ 1-201-949-0705 ihnp4!ho95c!wcs

Actually, it's an 8087-2. Does the same, but the chip is a little different. -- ## Bill Stewart, AT&T Bell Labs, Holmdel NJ 1-201-949-0705 ihnp4!ho95c!wcs
