Huh? Booting into RT-11, I find that the CSI won't even take "?"'s on a command line: Starting system from DU3 RT-11ZM (S) V05.07 .DIR ??????.??? ?KMON-F-Invalid command In RT-11 the single-charcter wildcard is "%". A similar error message comes from RSX, where the single-character wildcard is "%" as well. I don't know too much about RSTS (as opposed to RSTS/E). The only PDP-11 operating system I know that uses "?" for single-character wildcarding is XXDP (if you want to call it an OS...) DOS-11 might take it too. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

RCA Cosmac Dev. System IV update

RCA Dev System IV another update...

by dogas＠leading.net

From: technoid(a)cheta.net <technoid(a)cheta.net> >Excellent. What are the specs on the machine or do you know yet? The options installed in the machine are listed at: http://users.leading.net/~dogas/classiccmp/cosmac/cosmac.htm It's an 1802 microprocessor based system (of course) with 60K of ram, 15 slot (Microboard buss) "card nest", rom( ut21 utilities/monitor), parallel&serial i/o interfaces, integrated ascii keyboard and crt, extertnal dual 8" floppies (CDP18S801), and ports that tightly link in an external Micromonitor (CDP18S030) microprocessor ICE unit. CDOS, The disk based operating system has (I'm looking for) programs for full screen editing program and various levels of interpreters/compilers for Basic, Assembler, Pascal, etc... I found a source for the PLM compiler and MOPS (the Micromonitor Operating System) so the machine won't be completlely without software soon and I can already now hand assemble stuff and poke it in through the the ut21 monitor ;) - Mike: dogas(a)leading.net

RCA Cosmac Dev. System IV update

by dogas＠leading.net

I got everything cleaned up and after a scary session adjusting the horizontal hold near the hot end of the CRT, booted it into CDOS 4.1. The CDP18S801 Floppy Drive System (RCA Cosmac badged but from Pertec) is run off the parallel card of the computer. That seems to make them maybe portable across different systems. I can't do much with the machine however because all the disks that I have for it although bootable, don't have any of the other CDOS files. They all contain what appears to be EPROM dump files. Does anyone have any software for this system? God, I hope so... ;) - Mike: dogas(a)leading.net

RCA Dev System IV another update...

by dogas＠leading.net

The machine isn't the lame duck that I first thought. I just finished reading the UT21 Utility Commands There's a great monitor down there with easy disk access and a "bios (including uart)" Woo Hoo! It beckons... ;) - Mike: dogas@leading,net

Can a Mac Portable battery be "trickle charged"?

I expect it'll say what to do, but it may also assume that you're willing and able to dismantle the battery, fix it and then reassemble -- in the case of a 12V battery, repeat for all six cells!

Kind-of OT (but interesting): Raymond Scott

by af-list＠wfi-inc.com

There is a 2 CD compilation of Raymond Scott's electronic works (from the 50's and 60's) being released, which can be had before the official release date through raymondscott.com. Thought there'd be more than a few people on this list interested - my copy's on it's way. If you don't remember who he is, he's the guy who wrote all that cool Warner Brother's cartoon music, like Powerhouse and Dinner Music for a Pack of Hungry Cannibals. For those not interested in experimental electronic music (and to stay slightly on topic for the list), he inadvertantly contributed to computers as well with several patents on magnetic tape positioning equipment and sound generators. I know that IBM, HP, Atari, and others used his ideas in their own designs, sometimes years after he implemented them. Cheers, Aaron

Of course... a few more VMS questions... ;-)

Not failed, just not licensed. >Now, will that license be good for anything I install as far as software, >or will I have to get a license for every type of program I want to run? (I >sincerely hope the former... ;-) Mainly, I just want to do some C and >BASIC programming for now. that license covers a set of programs that happens to be on the hobbiest CD including C, Pascal, TCP/IP networking and a bunch of other things. VMS itself includes a fairly nice editor (TPU) and a raft of goodies. With DCL (command language{script}) you can do most anything. >And one other question which I've not found or figured out myself... How do >I get a directory listing of *just the subdirectories*? I've figured out >how to search for a particular filename or extension recursively thru the >subdirectories, but what's the VMS equivalent to DOS's dir /ad or linux's >ls -lAF|grep '/$' ??? {there are lexical functions in DCL with would do things that grep can do} Dir *.dir works! Directories have the extension .DIR. Dir [...]foo*.asm Will find anything in the current or subordinate directories that match that pattern. Dir [-]FOO??.A?M A ? is a single character wild card and the "[-]" says search the directory level above the current one. VMS directories start at [000000] and decend from there. so dir dka300:[000000] will get you the top level directoy of the SCSI drive on bus A with ID 3. Help dir will get you info. VMS is known for the rather rich set of operators that modify the basic action. My favorite device modifier... Set device=flamethrower/temperature:plasma You get the picture. I have a list of DCL functions, ailiases, and logicals that I use to make things friendlier. Most often used are: UP same as SET DEF [-] {cd ..} DO*WN decend to either list of availabile directories or create a new one. {only one level down from current} same asCD FOO or mkdir At some point once I have a web page going I should make the DCL scripts I use frequently available as they can be handy. No law says you can't create a ailias to do exactly what MKDIR, CD, REMDIR and friends do in the unix world. Implement them in DCL and insert the code/defs in the login.com file. Hint, system is a dangerous account like root. Create a user account with some privs as a safety net. Also every account should have a login.com which is like a DOS autoexec.bat though DCL is more powerful. Allison

Some of the demos are intended specifically to show off capabilities, or demonstrate how to program, the 24-bit or Z-buffered systems, so I wouldn't expect them all to work or even compile on an entry-level graphics system (if you only have entry-level graphics, some of the headers and libraries will not be there). > Mark Green wrote: > > > > > A student of mine has a circa 1990 SGI Personal Iris with GR1.2 > > > > graphics--apparently less than 8-bit.

Mark is right: GR1.2 is 8-bit. Some GR1.2 boards are apparently upgradable to TG (the next level), if the big chip in the middle is socketed rather than soldered (you replace it with a TG piggyback board). I *think* all versions can be upgraded to 24-bit. Whether you'd find an upgrade now is another matter, of course. -- Pete Peter Turnbull Dept. of Computer Science University of York

Opening CP/M files (.asm/.bas)

Most of the public domain stuff was in that data base at one time. I bought some disks from them in 1996 so I know they were still around them. There was a CPMUG on Compuserve also. Try that bunch for sure as they had several folks knowledgable in CP/M 2.2 and CP/M 3.0. Good Luck. Mike
