An other CP/M / MSDOS hybrid system. This computer had no great commercial success.
The Decision Mate V came with 128 KB of RAM, but could be upgraded to 256 or 512 KB with expansion cards. The serial and Centronics interfaces were not on the mainboard, but were added as expansion cards. An additional card with a 68000 was developed by NCR in order to use CP/M 68.
There were 7 expansion slots. An optional diagnostic card was available for slot 6. Otherwise, diagnostics were produced through 6 red LEDs on the back of the case, above the volume control.
The computer had two floppy drives, or only one + a Winchester hard drive mounted in the second bay.
A network called 'DecisoNet' was designed to link together several Decision V.
Yo trabajé de analista-programador en NCR durante varios años (1981-1986) y poseo desde entonces un NCR-DM-V que costaba 1.500.000 Pesetas (RAM 256MB, HD 10MB y disquetera 3 1/2). En España ese era su precio, por otro lado, más o menos lo que costaba un PC-IBM pero el NCR-DM-V era un producto de mejor calidad y mejores prestaciones. Lo tengo bien guardado, con sus disquetes de RM-COBOL, CP/M y MS-DOS y funcionando todo correctamente.

In Spain that was its price, on the other hand, more or less what cost an IBM PC but the NCR-DM-V was a product of better quality and better performance. I have it well saved, with its RM-COBOL, CP / M and MS-DOS floppy disks and running everything correctly.

I too was a proud owner of a DM-V$ I was working for NCR in Dayton when it was released but purchased it through the NCR Credit Union after transferring back to the field in Boise, Idaho in 1981. Great machine, but a little before its time. It had a unique boot system which made in incompatible with the IBM machines. It had fantastic graphics (from NEC) with 8 colors instead of the 4 colors that IBM had. I relocated the BIOS code in mine and tweaked it to use the 8 color display. I was able to run any PC app that used standard BIOS calls and did not rely on direct memory addressing. I demoed the machine at several Food $ Drug trade shows in Boise, Seattle, and San Francisco and could have sold several except it wasn''t supported by NCR. It really blew away the IBM in direct competition running the same software

I bought a second hand DM-V in about 1985, it was my first "Real" computer. It had the 10MB hard disk with two 5MB partitions, It would boot into CPM on the first partition but, if you used a DOS boot disk, you could access the second partition. I chose this computer becauser included in the bundle was a COBOL compiler and I wanted to teach myself COBOL. I only had it for a year, trading it in for a ''286 clone.
