Today I powered up the "new" 11/03-L, with which I have absolutely no experience. The POWER OK light blinked slowly on and off for a while and then went out. Now it doesn't come on at all. The top card in the cage, though, has a row of red LED's and a large green one, all of which are lit. Power supply is H7861, cage is BA-11SA. The cards from top to bottom are: M8189 2 Mb Clearpoint memory card (don't see a model number) M8061 M7957 M8053 Dilog CQ 1610 card (what is it? Many 2861 PLCC chips in sockets) M8029 I didn't see a lot of 11/03 manuals on the bitsavers site. Before I do a lot of searching and headscratching, can one of the -11 gurus tell me what kind of beast I've got here? Or point me to the appropriate manuals? thanks Charles

No, all versions, from the original 1981 version, support abbreviations. > The '?' token was used by BBC BASIC for peek and poke as I recall. Yes, that's right. '?' for byte values, and '!' for word values. You could do interesting things with them. For example, ?&400=0 means poke zero into (hex)0400 but &400?1=0 means poke zero into the address 1 higher than &400 -- this is useful if you replace either the '1' or the '&400' in my example with a variable, and use it in a loop. Or set a variable to the address of some buffer or control block, and then fill specific entries in the control block with values: 800 DEF PROCdiskaccess 810 returncode=10:parm?drive:parm!1=buffer 820 IF format THEN PROCformatparms:GOTO 850 830 parm?5=3:IF rnotw THEN parm?6=&53 else parm?6=&4B 840 parm?7=track:parm?8=sector:parm?9=&21 850 A%=&7F:X%=parm:Y%=0:CALL OSWORD [ result code processing and display here ] 890 ENDPROC which is a piece of a disk sector editor program I wrote in November 1982 (according to the REMs at its head). That particular bit is the procedure to set up a parameter block at an address "parm" (defined further up the program) and call an OS routine called OSWORD which with 7F in A (and the address in X and Y, in this case it's in zero page) calls the routine that accesses the 8271 disk controller. "CALL" in BBC BASIC copies the variables A%, X%, and Y% into the obvious 6502 registers and does a JSR to the address following the "CALL" keyword. All of which has very little to do with '?' as shorthand for PRINT! -- Pete Peter Turnbull Network Manager University of York

OS9 login / shutdown

by julesrichardsonuk＠yahoo.co.uk

I've just come across my first OS9 system, and know absolutely nothing about OS9 other than that it's vaguely UNIX-like. Before I try hooking the hard disk up and seeing if it actually works, obvious questions follow: 1) I assume there's a login process. Of course I don't know any account details for the system; are there any tricks to breaking in as there often are with old UNIX systems? 2) Assuming I can't log in at this stage, is it possible to cleanly shut the system down? e.g. some magic keypress or login name (as there is with Apollo machines) 3) If I can login somehow, how do I then shut the system down properly? Is there a shutdown command in OS9, or is it something else entirely? On the plus side, the interface between host and disk unit is SASI, so there's a chance I can do a raw backup of the drive via a modern system. On the minus side, the physical drive is an ST506 type via an OMTI bridge board, so I can't easily go from raw backup to working system without proper low-level format utils (which I don't have, although I'm still sorting through floppies that came in the same haul) Of course all of this assumes that a) the hard drive isn't toast already and b) that the hard drive which came in the pile of stuff actually belongs with this system in the first place :) ta Jules

CP/M 2 - what's its legal status?

by jplist＠kiwigeek.com

Hey there folks; Decided to move into the CP/M world a little with my Vector Graphic machine, which is expecting CP/M 2.0. I was curious what the legal status was these days? Since I find source code for CP/M, MP/M and so on online, I'm guessing the status is fairly free, but I wanted to check. I can also find CP/M 2.0 online - but I don't believe I have any way of producing a bootable 5.25" floppy disk of it. If the OS is in a free-as-in-speech state, would it be possible for someone to whip me up a 5.25" disk and ship it out to me (shipping paid for, of course) for the Vector? The Vector suggests 2.0, but it appears that 2.2 is the superior release of the 2 series, I'm hoping that this will work on the machine. My thanks to all; JP

brochure/flier request.

by Mark.Brennan＠ie.fujitsu.com

Hi, I am a systems engineer with Fujitsu in Ireland and I have a request I am looking for some help with. My request is some what strange to say the least. Since I joined Wang Computer in 1988 I have been collecting Product Brochures on various computer systems it started of with Wang Vs server systems. For the last few years I have been trying to collect old product/info/fact/marketing brochures on various computer systems with very little luck, as in the future I hope to set-up a web site with details and overviews of them. I have managed to collect some information on, DG/HP/Wang/Netframe/NCR/Tandem/DEC/Sequent/SGI/Siemens-Fujitsu/Pyramid/Apoll o/Cray/KSR/Ncube/ICL/Compaq etc, I was wondering whether or not you may have or know where I maybe able to get my hands on any old product brochures/fact sheets etc on any of the supercomputer/workstations/systems/servers, I know that my request is at best strange but any help would be great. Anything that is sent to me I will copy and return the originals if people still need them that is. Regard and thanks again markb.

BASIC's question mark and PRINT

by Richard.Cini＠wachovia.com

That was to permit parsing the table for the end of the keyword. Although I haven't investigated other BASICs, I know for a fact that Commodore BASIC used that method. Supposedly, all of the micro BASICs were compiled from the same source tree using a bunch of #if/#endif-like switches. ISTR that Microsoft used some sort of intermediate language or series of complex macros to facilitate being to compile a version of BASIC for almost any machine. Indeed, ASCII(63) is the question mark character. -----Original Message----- From: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Gordon JC Pearce Sent: Monday, November 21, 2005 4:09 PM To: On-Topic and Off-Topic Posts Subject: Re: BASIC's question mark and PRINT Jim Battle wrote: > Allison, that seems unlikely.

Aha - didn't the last letter of each keyword have bit 7 set? That would mean that it would be 63+128 = 191 Just a thought. Gordon.

Wnated : Front panels and eject buttons for Sony MFD-63W-00D

by ard＠p850ug1.demon.co.uk

OK, it's a _very_ long shot. As you know. I am sorting out this Acorn Filestore. I have 2 floppy drives that were sold to me with it, and which I believe might well have been the original type of drive for that unit. They are Sony units, marked MFD-63W-00D one a label on the side and Model MP-F63W-00D on a label on the motor cover plate Alas they are missing the front bezels and eject buttons (I suspect they came from an Acorn Achimedes). So, does anyone have a couple of scrap drives of that type that I can obtain the bezelz/buttons from? -tony
