160.0. "VMS 5.5-2H4 on DMCC" by ACISS1::ROGERSR (hard on the wind again) Fri Jan 24 1997 19:37

    I've run into a common need at more than one account. The need is
    provide a VAX/VMS solution on DMCC platform. This is an installed base
    driven needs as Rapiston Demag, Distribution Control Systems, Goss
    Graphics Systems, and Digital Electronics Automation all have aging
    VAX/VMS installed bases. (MV31-3400). All these customers also have
    end of life plans on the VMS engines and are moving to WNT. 
    
    What they want to do is sell only DMCC boxes from this point forward.
    They also want offer performance upgrades that are not based on MV
    technology.
    
    It is probable that an N-VAX based DMCC board is not likely. But might
    there be a software solution ala Viking concept? All these clients have
    application software stuck in the pre-Alpha days. V5.5-2H4 or something
    like that. Probably, a tranlator running on a K2 or Takara would blow
    away any MV3100 or MV4000, yes?
    
    Just how big is the installed realtime MV3XXX base? I'll bet its larger
    than most people think.

160.1	What else is needed besides DECmigrate ?	BBPBV1::WALLACE	john wallace @ bbp. +44 860 675093	`Sat Jan 25 1997 11:48`	5
	Would you, should you, trust DECmigrate in a production environment ? Here today, for free, VAX binaries translated for Alpha OpenVMS. Caveats? If that's OK, what about I/O (though by definition there isn't much in a 3100!)?
160.2	True...but not fast, easy, or cheap	SHRCTR::WADAMS		`Mon Jan 27 1997 14:06`	17
	True about the VAX installed base and where they are frozen code wise. The Catamount program aims to hit some of this installed base. There are many challenges for DMCC to target this market. It is all a matter of engineering dollars (backed by a sound business case....that migration would occur.....I'm would guess Alpha OVMS has similar business cases that showed how the installed base would move over...but did not.) Engineering would need to address OVMS 5 as another OS to support plus spend a lot of cycles looking at VAX peripherals and outdated busses (for option support.) Given limited engineering cycles....the question might become...would your chose between the next Alpha chip or a specialized program to target the VAX base. Wayne
160.3	binary translation?	RTOEU::EGAUTHIER	AUA - Another Useful Abbreviation	`Tue Jan 28 1997 09:12`	5
	I assume there are drivers involved here? Therefore the binary translation technology we have is not suitable? -Eric
160.4	More dedicated, less embedded	ACISS1::ROGERSR	hard on the wind again	`Tue Jan 28 1997 21:57`	8
	In three cases out of four, no drivers..... A difference of 32bit code verses 64bit code. I'll look into DECmigrate... -Rod
160.5	Catamount unlikely	ACISS1::ROGERSR	hard on the wind again	`Tue Jan 28 1997 22:03`	13
	two words about catamount... too late! should have been here a year ago. All (100%) of my MV3/4xxx bix is gone. Last two orders last month.. I have no customers left to sell Catamount to. In most cases, the win-back effort is moving them from commercial PC's to DMCC. What makes that difficult is lack of onsite support, something they used (100%) with MVxxxx and still do with the PC's.
160.6	VMS: Minimum Level	CIMCAD::PIERSON		`Mon Mar 17 1997 16:47`	8
	Minimum level of VMS for ebm43/44 (k2) VMS 7.1. Minimum level for VMS for ebm21/23 (takara) VMS 7.? (EBM21/3 has not been settled, yet...) thanks dwp
