PDP 11/23+ progress

by jim＠g1jbg.co.uk

I finally managed to get my OEM 11/23+ to boot from the RL02 today, the solution to the OEM boot ROM problem was to set the RLV12 addressing mode to 18 bit, rather than 22bit. I assume that this is a feature of the OEM boot program :-) I'm now getting garbage on the terminal, but have yet to figure out which setting I've got wrong! Jim.

Registry for terminal DA responses?

DEC published what they did. Private in this sense was defiened in ISO/ANSI as undefined by them and available for implmentation if the VENDOR elects to have said functionality. The ANSI defines were quite limited and far for complete. Then there were those vendors that use something else before ANSI and wished to continue with them for customer loyalty. That fragmented the market, ANSI/DEC compatable and NON ANSI/DEC compatable. >DA (CSI c) is not a DECism, it's a feature of the International Standard >ISO 6429.

The DEC was was to keep their terminals compatable with prior version that had existed since the mid 70s. Or differently put, new terminals should not break the customer (they did sometimes anyway!)! That was part one. Part two of that is multinationalization was a POST VT100 event. By Time DEC started with Multinational products VT220 and some of the VT1xx vairents were out the door or about to. The whole process of multinational products would over the next 10 years undergo several variations to meet the market as it changed. One thing to remember. ANSI was always after the first product and rarely covered all the varitions in the field. And like it's IEEE and ISO cousins was subject to interpretation until the market forced everyone onto the same sheet of paper. Allison

Believe it or not NONE of the competing terminals tested inside DEC met more than 90% of the VT100 sequences (as of 1989ish). They always broke in some way usually benign but a few would require reset (power off/on) to correct. The testing was condusted by the same group that validated VT100 through VT420 (maybe further) and all VT emulations that were non terminal (decwindows,VT1200, and the like). >Any reason you don't want to use the (so-called) "ANSI" vt-100 type >sequences or those from, say, a vt525, for your 'termainal application'? I can think of one. The average VT100 emulation is poor at best and fully broken most times. Vt100 was a family of terminals, also the capability varied so the escape sequences were extended using ANSI private. The only stuff I've seen that behaves accurately is VT52 emulation, mostly because VT52 was so limited compated to VT100. Allison

No, I have to look it up every time and I have at least 5 versions that have different jumpers. Likely specific to Altos (I dont have one of those). I do know my DEC systems require different setups from other machines I have. FYI: any drive that is equivilent to a Either: TEAC FD55Fxx (two sides 96TPI DSQD only) TEAC FD55Gxx (Two sides 96TPI DSQD and HD1.2m) Will work. That includs a few Toshiba, Mistubishi and odd brand named drives from the late AT286 into the early 486 eara. Allison

And why are you not doing anything about it? Why have you not yet enlisted in the revolutionary army? Face it, people - the various nation-states that have mutilated the face of Mother Earth by graffitiing it with national borders that serve only to divide people and to pit them against each other are our enemy, the enemy of humanity and the enemy of all life. Their sole function is to impose tyranny on humankind, both direct and indirect. The former is manifest in their "governments" and "laws", or more concretely, in the apparatus of repression, persecution, battery and murder which they call police and military in their "politically correct" speech. The latter is manifest in these "governments" and "laws" granting a license to the other group of criminals against humanity - corporations - to exercise tyranny of their own, and using the Orwellian police/military apparatus to shield those corporate criminals from people's rightful justice (such as a lynching). This tyranny is fundamentally at odds with the inherent rights of every human being on Earth, which are life, liberty, integrity of body and spirit, and realisation of happiness, and it is the duty of every one of us living on the bosom of Mother Gaia to stand up for our mother planet in Her time of need, when all Her sweet soil is trampled on by black souls who have no right to live, much less to rule - it is our duty as members of the human race, which has been entrusted with dominion and care of the above-terranean world, to rise up against the tyranny that is being imposed upon us and upon our planet, and to free the Republic of Terra of these criminals so that the bosom of Mother Gaia, Her sweet soil, can be free once again! This is a call to arms. The tyranny has reached the critical point at which no citizen of Earth has any moral right to sit idle and watch the boot stomp on the human face. Every one of you has a duty to take up arms and declare war against the illegitimate nation-state that illegally occupies the land you live on. People of the world, rise up to be Free! -- Michael Sokolov Starfighter and Chief Philosopher Interplanetary Internationale (business) http://ivan.Harhan.ORG/Internationale/ (personal) http://ivan.Harhan.ORG/~msokolov/ Proletarians of all planets, unite!
