Has anyone seen or used ATT's new MSDOS/UNIX micro? I am told that it
will run both operating systems concurrently (not emulate). I am trying
to find out what comes with their UNIX System V. Is it the same system that
comes with the 7300? Are the utilities and development tools sold as a
seperate package or do they come with the system? I have called ATT, and
their local reps, but no one seems to know the answer to these questions.
Thanks.

Some of the info I have on it says that UNIX V will not be available until 1Q85. My opinion (and only my opinion) is that it will not be the *same* system as the 7300, as the 7300 is a 68010 cpu and the PLUS is a 80286. The user interface is supposed to be the same, though (the UA perhaps?). I have no info on how the software will be sold/packaged. With UNIX, it will have a facility called OS MERGE, which Infoworld (oct 14, vol 7, issue 41) says was developed by LOCUS Computing of Santa Monica. OS MERGE will allow MS-DOS to run as a process under UNIX. All files on the hardisk will be accessable by both UNIX and DOS and will be converted to the appropriate format on the fly. I'd like to know what format the files are actually stored in on the disk. Insofar as the hardware itself is concerned, mine have 20meg hardisks, a 1.2 meg floppy drive and came with 512k in one bank of the mother- board. The other bank had empty chip carriers, which I populated with another set of 256k chips, bringing it up to the max of 1meg of memory (on the motherboard). It is the same physical package as the regular 6300 (6300 MINUS, perhaps? :-) ). It came with MS-DOS 3.1. The CPU is a 6mhz 80286, and is supposed to run with no memory wait states, which is supposed to make it up to 25% faster than an AT. Running Peter Norton's system information utility (SI) produces a performance factor of 7.2 times an IBM/PC for the 6300 PLUS (the regular 6300 yields a 1.9 performance factor). Does anyone know what SI produces on an AT? -- +--------------+------------------------+-----------------+ | Mike Vrbanac | AT&T Bell Laboratories | Columbus, Ahiya | +--------------+------------------+-----------------------+ | Unix: {cbosgd|ihnp4}!cbuxc!gmv | CompuServ: 76054,113 | +---------------------------------+-----------------------+

I was a beta test site for the 6300+ and have found it to be compatible with everything I tested. The performance is better than a stoce AT, but not as good as one at, say, 8 Mz. Since the "new" AT supposedly will have a ROM limiting the system to 6Mz, this may be important. I also tested the Zenith Z200 with PCDOS, PC/IX and XENIX. All run. 8 Mz, no wait states, up to three hard disks. XENIX5.0 supposedly coming. Still a horse race here.
