Multi-User Star Trek and other Games for RSX

[Mark Matlock]

   In another thread there has been an interesting discussion of various games that can be played under various PDP-11 operating systems.

One of my favorites has been MTREK or Multi-User StarTrek. Up to 8 players can play against (or together against other) players or robot

ships. This post is about how to find and install the programs necessary to play it.

   First, this software and over a decade of RSX SIG tapes (approximately 500 MBytes) are all available for download. This is also described

on page 31 of the PiDP-11 user manual as well and you may have already downloaded this but if not...

cd /opt/PiDP11/systems/rsx11mplus

wget http://rsx11m.com/PiDP11_DU1.zip

unzip PiDP11_DU1.zip

Reboot the PiDP11 into RSX (SR switch to 1, depress Address knob) After booting DU1 should automatically be mounted.

>SET /DEF=DU1:[1,1]

The latest version of MTREK is on RSX83B.DSK which can be found by searching the *.TXT files with GREP or MOR as described in manual

The MTREK files are in [307,110] and we need to copy them to DU1: to make sure we have plenty of free disk space.

Hmmm.. No prebuilt tasks so we will have to compile from the sources.

Ok, let's look at the MTREK.CMD

>TYPE MTREK.CMD

A long listing follows but it is clear that this is the build command file.

It is also apparent that MTREK is written in something called RATFOR which is Rational Fortran (an oxymoron?)

Anyway when I did a directory of all the files in [307,100] the .FTN files are there so we don't need to process

the .RAT files into .FTN files.

SO, let's try it.

Wow, no errors! What Luck!

Read MTREK.DOC to learn how its played, then

>@MTREKUP

You will be asked for a random number to build your unique Universe, Install the memory common that holds the universe,

install the MTREKD daemon that moves stuff around, and install the MTREK ships and Robot ships.

Also MAP.TSK will create a large text file UNIVERSE.MAP to guide you to "Boldly Go Boldly Where No Man has Gone Before"!

This is a collection of arcade games (PACMAN, CENTIPEDE, MISSLE COMMAND, that use VT100 graphics and some incredible escape sequence coding again in that

RATFOR language. The .TSK files that DO NOT use the FSL (FCS Supervisor Library) will run fine. They have .DOC files to explain them and are best played at 9600

to 19200 baud terminal.

The last game in this directory WONDER.TSK is one I am not familiar with. It won't run because it links a FSL library from an earlier version of RSX. There is a .TKB

file which can be used to task build it but it is also broken. Fixing it is not hard if you are familiar with RSX but if you are not edit the file to the following:

>TYPE WONDER.TKB
WONDER,WONDER/MA=WONDER,UVT100OLD,LB:[1,1]F77FCS/LB
/
SUPLIB=FCSFSL:SV
ACTFIL=1
UNITS=5
//

then you can:

>TKB @WONDER.TKB

Also, as Johnny Billquist points out, he has many additional games running on MIM and that is a great place to try them. One of my favorites there

is "Leather Godesses of Phobos" which I bought originally for my Atari 1040ST complete with the 3D glasses and scratch and sniff card.

Have Fun,

Mark

[oscarv]

Mark,

Something to do tonight, thank you!

One addition: if you have run RSX before, an empty/dummy PiDP11_DU1 file was generated by simh. So just to be sure that's out of the way:

cd /opt/PiDP11/systems/rsx11mplus

sudo rm PiDP11_DU1.*

sudo wget http://rsx11m.com/PiDP11_DU1.zip

sudo unzip PiDP11_DU1.zip

Kind regards,

Oscar.

[Radioteacher]

Mark and Oscar,

Thank you for starting this thread.  I should be back on track to work on this later in the week.  

Of all the things I did not have in my parts drawers are 1uf caps for the MAX232's.  

Have a great week!

Paul

[Oscar Vermeulen]

Paul,

Best try before you rely on me but I think the 1uF value is noncritical. 10 uF will do just fine.

Kind regards,

Oscar.

Oscar,

I am sure you are correct but I only have two of those plus aesthetically, I wanted all of the caps to match.  

After a number of searches, I realize that my parts collection has a gap in this area.  So I ordered a 10 value range of 50 pieces of each value kit to fill in my supply.  This costs less than a typical lunch and should last me...forever.

I will simply add this to my parts collection.  

Years ago, I was able to stock up when a local parts house went out of business.  They were selling a 3 cubic foot box for $50.  Anything you could fit in the box was yours.  I first cleaned out the tips for my Weller solder station first and moved on to passive and active components.

Hi Mark - can you give me some advice on how a noob might install F77?  I got as far as typing @MTREK, and it asks me....

Do you want to preprocess the RATFIV source? [Y/N]:N

*** The Fortran 77 compiler is not installed.

      Please install it (as ….F77) and rerun this command

cheers!

Andy

It then 

[Mark Matlock]

Andy,

    The easiest way to get F77, as well as BasicPlus2, C, APL, Pascal, Cobol, DECnet, Johnny Billquist's TCP/IP and also have 8 DZ11 ports is to boot the version of RSX that on the disk image labelled 

PiDP11_DU0.dsk

    That disk image was SYSGENed for a PDP-11/70, with 4 DU drives, 4 RL drives, a MS tape, an MU tape, an RX02, a card reader, DZ and DL serial ports and a TU58. It was NETGENed for a DELUNA, has LAT in case you have a DECserver for more serial ports. That image is normally located in:

/opt/pidp11/systems/rsx11mplus/

    this is also where you want the PiDP11_DU1.dsk and it will have a boot.ini that should attach both of these images. This is the version of RSX that boots with switch 1 set.

   If your copy got overwritten, you can get a new one from the same place as the DU1 DECUS disk

cd /opt/PiDP11/systems/rsx11mplus

wget http://rsx11m.com/PiDP11_DU0.zip

unzip PiDP11_DU0.zip

   If you are using a version of RSX that you have already customized and just want to install F77, The rsx11mpbl87.dsk image that

almost all of us are starting with has a F77 distribution in DU0:[246,246] with the latest patch files for it in [246,200]

The process is actually too lengthy to put in a post here but the manual that has the instructions is:

http://www.bitsavers.org/pdf/dec/pdp11/fortran/AA-K503B-TC_F77inst_Sep81.pdf

   The easiest by far is to use the PiDP11_DU0.dsk image where all that work is already done.

Good Luck,

Mark

[oscarv]

Andy,

Also - now you got your serial terminals working, the suspicion is they will work on the regular DU0 system as well. As Mark mentioned DZ was configured on that image (his 'frodo' setup) as well.

Kind regards,

Oscar.

[andy]

Thanks Mark, Oscar

OK I will copy that .DU0 over to the rsx11mplus folder.  I'll leave my boot.ini stuff the same yeah?

Will report back!

cheers

Andy

[Mark Matlock]

Andy,

   Yes the default boot.ini should be correct. To be absolutely sure, verify it has the following lines:

set rq0 autosize

attach rq0 PiDP11_DU0.dsk

set rq1 autosize

;enable this line when you want to use the DECUS disk image collection

;which comes on a separate 1.7GB disk:

attach rq1 PiDP11_DU1.dsk

   Oscar has pointed out that when this boot.ini runs and you don't have a PiDP11_DU1.dsk

in that folder Simh will make one for you. This can be a problem when you download and try to unzip the big 1.6 GB DECUS disk.

Best,

Mark

[andy]

thanks again for guidance Mark!

OK - so I wgot and unzipped the DU0 dsk from rsx11.com into the systems/rsx11mplus folder.  Adjusted the boot.ini to refer to the correct dsk etc.  And when I reboot I get the correct RSX11 starting up... I assume it's correct because it asks me if I want to start up LAT, TCPIP etc.  However unfortunately I don't see the "DZ Simulator started" message on any of my terminals nor can I  get to the > prompt from any terminal.  Everything else I am sure is OK. If I do con dis for tt I see something that looks like lots of terminals mapped. And my /dev/TTYUSB0-3 devices are present as before.

About an hour ago my same terminals seemed OK using the Manfred disk.

Not sure if this factors into things but I also have in my .ini

set dz enable

set dz modem

set dz lines=8

Followed by my  attach dz line=0-3,connect /dev/ttyUSB0 -3 etc lines

I appreciate the help. I surely must be getting close!!

cheers :-)

[Mark Matlock]

Andy,
In the boot.ini for the RSX I set up there is a line:

attach dz 10001

Did you remove it?

Also, you should have:

set dz enable
set dz lines=8
set dz address=17760030
Set dz vec=300

attach dz line=0-3,connect /dev/ttyUSB0 -3

The last line should be your line that works in the other boot.ini I think two things could be involved,

I normally use the dz to handle inbound telnet connection to Simh at port 10001 that then appear like physical RS232 lines to RSX. That is the attach needs to be commented or removed.

Second, the RSX I sysgenned is expected the dz to appear at CSR 177760030 and VECtor 300
If this is not defined to Simh, I’m not sure where it puts the dz. If this needs to be changed the RSX CONfigure command can be used to show what Controllers RSX has configured where.

Apologies Mark I meant to include this output:

[Johnny Billquist]

Andy, in your simh.ini, you set the DZ11 to CSR 160030, with a vector of
300. The CON output shows that RSX is expecting a CSR of 160030, and a
vector of 330.

You obviously needs to change one side or the other, so that the two
agree before things will work.

Andy,

    Johnny is exactly right! I think I made a typo when I was transferring lines from my boot.ini to the forums editor.

it should be:

set dz vec=330

    It needs to match and it is easy to change in boot.ini

Just one more tiny question :-)   I am on page 41 of the manual. Building MTREK from Fortran using the @MTREK command.

Everything goes nicely until the end

If I dare try and run @MTREK I get a variety of errors - Partition TRKON not in system, defaulting to GEN

and a bunch of file not found errors.

Thanks as usual for any help!

Andy

[Johnny Billquist]

F77OTS? I would have expected it to want to link with F77FCS...
Check and change in MTREK.TKB?

(And check that you have LB:[1,1]F77FCS.OLB)

Also, the warning about partitions are pretty harmless.

Hey guys, I EDTed  mtrekd.tkb, mtrek.tkb, mtrekini.tkb, robot.tkb and map.tkb.  Changed all occurences of F77OTS/LB to LB:[1,1]F77FCS/LB

[andy]

Now all I gotta do is learn the game!

Thanks for all the amazing help. 

Andy

[Mark Matlock]

Andy,

    The game is a lot of fun when you have two or more players logged in along with a few robot ships.

Best,

Mark

Andy,

   If your terminal has the VT100 graphics characters, you might want to also try the Pacman game that I mentioned in my first post of the thread. It is on the RSX83A.DSK in directory [312,354]

   The PAC.TSK will run without compiling or task building.

Best,

Mark

[andy]

Thanks Mark for the tips.... our gaming was temporarily thwarted by rather quaint access controls....

But we fearlessly change the time and tackled PAC, MSL and CEN

CEN (century?) was definitely a big hit.

OK well I think the next task is to digest the MTREK manual.  cheers!

Andy

[Johnny Billquist]

CEN is Centipede, and you clearly do not have a terminal with the VT100
DEC Graphics font. :-)

ah thanks Johnny.  Well the terminal is a Zenith Z-19-CN (c.1981?) which claims Zenith or ANSI escape sequences. Was hopeful that ANSI was something akin to VT100 but clearly not :-)

[Johnny Billquist]

It's not actually the escape sequences that are wrong. And you can play,
as you noted. However, DEC VT100 is first of all implementing the ANSI
escape sequences plus some "private" extensions.

However, the thing I reacted to was that your terminal do not support
the DEC supplemental character set, so the visuals are just wrong.

Here are screen shots from the four games in there, so you can see how
they should appear.

[andy]

Well that makes more sense, thanks Johnny.

The funny thing is I have a "VT100 compatible" Informer 207 terminal which is a neat little unit, but I haven't quite figured out how to get it to send things like ESC or square brackets.  As I have learned.... I need those square brackets for things like [312,354]  :-)

[Johnny Billquist]

Just as an FYI - RSX also accepts <> as an alternative to [] for
directory specifications.

Hi Andy, the Z-19 is nearly identical to the terminal used in the H-89 integrated computer that I built a number of years ago. It supported both a Zenith/Heath protocol as well as VT100/ANSI protocol. The Zenith protocol is effectively a VT52 and is the default. The VT100 protocol is activated by the sequence: ESC <
You could try this by pressing the Off Line key at the top left pressing ESC then pressing < then pressing Off Line again. Now, the next time the game redraws the screen you should see the character graphics.

[andy]

Hi Neal -  appreciate the tip - I did not know that!

cheers

Uh... No...

Andy's problem was not that he was in VT52 mode. If you look at the
screenshots he provided, you can see that the cursor addressing was
working just fine.

It is all about a font problem, which is about needing something that is
more than ANSI. The VT100 is a superset to ANSI.

Johnny

[andy]

Yep Johnny -no way round it. I do need a real VT100 (or later)

In desperation I was also trying to get my Kaypro to connect (it claims to be VT100-ish with the keypro term program) but I could barely get any kind of reasonable connectivity at 9600. Kept losing random characters (I read somewhere that it cant really keep up with itself)

Anyway..... if there's anyone out there who needs to unburden themselves of their VT100 (or later)  do let me know :-)

 cheers!

Andy

[Tom Lake]

You can usually get a VT-320 (in setup it allows you to choose VT-52 or VT-100 mode as well) a lot cheaper than a real VT-100. I just bought one with an amber screen for less than $250.00 US and it included the keyboard. Try to get a real VT-100 for that price!

Tom L

[Neal G.]

The "ESC <" sequence was worth a try. The H89 documentation is full of references which make it appear that its design is essentially a Z-19 and H8 packaged together in a single box. But perhaps Andy's Z-19 is not quite the same as the H89 terminal portion as I assumed. Here's what I see on the H-89 screen when using the ANSI sequences to switch between alphanumeric and graphics modes.

[Johnny Billquist]

You might want to look into enabling XON/XOFF flow control in the
terminal, and make sure it's enabled on the RSX side. At which point,
you might be good.

[Johnny Billquist]

Not only that. I would say that a VT320 in general is a better terminal.
The only issue is the flyback transformer that have a bad habit of
giving up in the VT320.

You will probably not even need to set it to VT100 mode, but it will
work just fine also left in VT300 mode. The differences relates to some
keyboard behavior, some additional functionality of the VT300 series,
and 8+bit characters and controls, which a VT100 series do not have.

[Johnny Billquist]

Thanks for that output. That looks "funny". IBM PC graphics?

On a VT100 you don't have a graphic mode, but you have different fonts.
One font is the DEC Tehcnical font. If you select that one, the output
looks like this (doing a similar printout as you did).

Noticeable is that the escape sequence to change fonts on a VT100 is
probably very different than the switch to graphics mode that you are
playing with.

By the way, the program I used for this looks like this (very simple
BASIC+2 code):

===
10 PRINT CHR$(I); FOR I=95 TO 127
20 PRINT ESC+"(0"
30 PRINT CHR$(I); FOR I=95 TO 127
40 PRINT ESC+"(B"
===

[Neal G.]

IBM PC Graphics, no the H89 predates the "PC" by several years. You're correct though; it ignores the "(0" or "(9" sequences. The sequences in and out of graphics mode are "[10m" and "[11m". All preceded by ESC, of course.

My comment about IBM PC Graphics were because the graphic characters
looked a bit like the ones from the IBM PC. But I didn't do a full check
to see if they actually matched in any way.

But it was immediately obvious that they did not match the DEC Graphics
font.

So I guess this was a private extension done in that terminal, which
don't match anything else I know about.

I'll do a quick explanation of how the VT100 works here, anyone not
interested can skip it.

The VT100 have two active character sets, called G0 and G1. Each can be
assigned to an actual character set. The assignment is done with ESC ( n
for G0, and ESC ) n for G1.
(The VT200 and newer also have G2 and G3, assigned with * and +)

The 'n' tells which character set to use.
0 is the DEC Special Graphics.
A is UK English
B is US English
7 is Swedish

the list goes on, there are a whole bunch of them. And these are all the
national replacement character sets, which were used back in the days of
just 7 bit characters. There is also the Latin-1 high part, which can be
combined with the US English, and together they would form the full 256
character set, if you have a terminal that handles 8-bit characters.

But this only covers how to assign a font (or a character set) to the
G0/G1 character set. The next step is that there is yet anything mapping
selecting which set is used when printing. For a VT100 this is pretty
straight forward. You select if you print using G0 or G1. On a VT200 and
newer, this mapping is actually split in two halves, where the VT100
part becomes the "left" mapping, and you also get a "right" mapping for
characters 128-255. And each have a selection of G0-G3.

You can then also switch to G0 or G1 for just the next character, or
permanently. On a VT100 there is single shift 2 and single shift 3,
which just do it for the next char (ESC N and ESC O), and the locking
shift 0 and locking shift 1 (SI and SO).
(Of course, with the VT200 and newer, this also becomes a larger set of
functions, since you also have G2 and G3, as well as the ability to map
each one to both GL and GR).

So, as you could see in my program, I just swapped in the DEC Graphics
into G0 and printed, and then swapped back US ASCII into G0 again at the
end of the program.

I could also have mapped the DEC Graphics into G1, and then just done a
LS1 to print graphics, and LS0 to print text. And swapping between G0
and G1 with locking shifts is just one character (SI and SO respectively).
