Yep. I think you are right. I had the B and device code switched. -- Bob Ammerman RAm Systems -----Original Message----- From: cctech-bounces at classiccmp.org [mailto:cctech-bounces at classiccmp.org] On Behalf Of Erik Baigar Sent: Tuesday, June 03, 2014 3:44 AM To: General Discussion: On-Topic and Off-Topic Posts Cc: 'General Discussion: On-Topic Posts Only' Subject: RE: Data General desktop info Hi, I think if this is similar to the Rolm's virtual consoles, the correct syntax would be to enter the device address followed by "B" for boot. i.e. "33B" would do a channel boot from the floppy drive (Miltope type). "T" would print the current register contents, and an octal number followed by "/" would print the memory's contents of the address given and wait for the input of a new value. Just enter keeps the original value and steps to the next memory location. Best regards, Erik. On Mon, 2 Jun 2014, Bob Ammerman wrote: two-digit octal device code. You can't hurt anything by trying invalid codes, although the machine may lock up until you recycle power. machine, but try something in the 20's or 30's.

Boy is my memory faulty. I spent 3 years working for DG as a systems engineer and many more doing DG stuff for my own customers. Old age, I guess. I checked a listing of DG device codes from an MV/20000 functional characteristics manual. If there is any consistency between that world and the Desktop Generation world then you should try 33L. At worst just work thru the octal numbers from 01 to 76 (00 and 77 are reserved device codes for the CPU itself). -- Bob -----Original Message----- From: cctech-bounces at classiccmp.org [mailto:cctech-bounces at classiccmp.org] On Behalf Of supervinx Sent: Thursday, June 05, 2014 4:14 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: RE: Data General desktop info Il giorno mar, 03/06/2014 alle 07.31 -0400, Bob Ammerman ha scritto: Ehm... nB sets breakpoints (max 8) B alone displays the breakpoints... The right command should be nL Load from device But I don't know the correct device number. I tried some codes found in internet (but infos are really poor), with no activity on the floppy drive or on the hard disk.
