From: wss at Lll-Unix (Walter Scott - Consultant/SC) Date: 9 Dec 1982 at 1710 Pacific Standard Time Does there exist UN*X for the IBM 4341? I'm pretty sure that there are C compilers for that machine, but I don't know where they could be obtained. I'd appreciate hearing from anyone who knows the answer to either question.

Amdahl's UTS is UNIX-on-VM. It is expensive. Does anyone on Usenet currently use it? TUCC (Triangle Universities Computation Center) tried it two years ago, but cancelled the project in favor of a huge MVS/TSO system. The project head was Steve Bellovin (unc!smb still works), with Dennis Rockwell (mcnc!dennis) and myself (duke!trt) part time. The following info is about 2 years old, but I bet it is still valid. UTS is half-duplex, its biggest problem. Its other big problem is that it runs under VM which is a 20% cpu slowdown unless you have less than 2 Mbytes of primary in which case it is a 60% IO slowdown (1 or 2 users!). A 4341 group 2 with 4+ Mbytes supports about 2/3 as many people as the same machine running CMS/VM. These are mostly guesses, for more info contact unc!smb. Tom Truscott

Yes, there is in fact a C370 compiler that runs under VM/CMS, and I'm told that Amdahl actually has ported Unix to the 4341 architecture and has it running under VM. (i.e. it would be VM/UNIX as opposed to VM/CMS). For those who don't know, Amdahl is the company that makes IBM lookalikes (same architecture as the old 370, and hence upwards compatable to 4341s).

I have been using Amdahl's UTS on an IBM 3081 (and have used it on a 3033). While this is a fair size bigger than the 4341, I think that it's safe to say that it is still more productive to use UTS on a 4341 than CMS; it certainly is more productive on a 3033. UTS does work a lot better if you're using mostly full-screen devices - 3278's or the Yale Series/1 emulations. Amdahl has recently installed paging in a new (Version 2) release of UTS. We should be getting V2.0 here at P.U. pretty soon and I'll let you know how it goes -- I'm responsible for dealing with UTS around here. It is pretty expensive, by the way -- $10,500 per year for Educational use, $15,000 (I think) for commercial use. I wish I could get the Amdahl people onto the net. -Scott E.

From: Mark Weiser <mark.umcp-cs@Udel-Relay> Date: 13 Dec 82 23:11:15 EST (Mon) Amdahl has a port of version 7 to IBM 4341's under VM. They call their Unix "UTS" (Universal Timesharing System). It leases for $15000/yr to commercial customers, $10000 to Universities.

From: mo at Lbl-Unix (Mike O'Dell [system]) Date: 15 Dec 1982 13:27:34-PST At the Boston Usenix meeting AT&T publicly announced the availability of Unix/370. I believe this is what you have in mind. -Mike

So, tell me ... How does one allocate a Partitioned Data Set in Unix? What is the syntax of the C-Shell's JCL? Is there a termcap entry for 3270 series display stations?

UNIX/370 developed at BTL runs on most IBM processors, from the 4341 to the 3033AP (soon on the 3081). UNIX/370 equivalent to SYSTEM III is available from AT&T thru usual license arrangements. I can post more details if anyone is interested. ian johnstone mhtsa!ianj
