Re: i860: Re: modern stuff
OK, I assumed the 6611s used the NSFnet type cards. Artic960s are different animals - but probably very similar in idea. My memory is hazy, but I think the NSFnet cards were referred to as Hawthornes. Somewhere around here I have one of the really early 386 based routing cards - a weird double height Microchannel card (the RS/6000s were RPQ'd with extra tall chassis to accommodate them). Anyway, I would like to get a 6611, but I do not think very many were made at all. -- Will On Thu, Nov 1, 2018 at 6:19 PM Paul Berger via cctalk wrote: > > The machine type was 6611 and there where three model, the smallest was > based on a 7011 the mid size one was based on a 7012 and the largest was > based on a 7013. > > The base card is an Artic 960 card which is just a processor card with > some memory that gets an application loaded on the fly.

Re: i860: Re: modern stuff
The machine type was 6611 and there where three model, the smallest was based on a 7011 the mid size one was based on a 7012 and the largest was based on a 7013. The base card is an Artic 960 card which is just a processor card with some memory that gets an application loaded on the fly. The top interface card has a lot to do with determining what the function of the card sandwich is, there should be a X-Y type code on the back of the card that would define the interface. They where used for all kinds of things like Synchronous communications, X25 and network accelerators. Some of the interfaces cards used in the 6611 where unique to it and never made it to the "standard" RS/6000 line. There was also a PCI version of the Artic 960 but by the time it came along the 6611 was long gone. Paul.

Re: IBM Xstation 140?
If I recall correctly the Xstation 120 (the first of them) used an 8086 (might have been an 80186). The big issue was that you couldn’t do anything with it because what was in ROM/FLASH was only smart enough to be able to TFTP the rest of the microcode (not terribly useful if you don’t have the image it wants to TFTP). I think the 140 fixed that (and is somewhat telling from all of the Intel flash parts on the board). But I don’t know what CPU it’s using. The IBM metal can is probably the graphics controller.

I do wonder how well software that used said peripherals dealt with COM ports above 4. SOME of those devices didn't need the full set of COM port capabilities.
