Here are the three page about the VAXSTATION 520 from the: VAX PDP-11 Systems and Options Catalogue European Edition Autumn 1985 Congratulations! Ulli

You've obviously got the "VS5XB VS500 GRAPHICS SUBSYSTEM", which is the graphics part of a VAXSTATION 500 (if paired with a MicroVAX I) or of a VAXSTATION 520 (if paired with a MicroVAX II). Both models seem to bee very rare. I let you know when I found out more. Ulli

Who knows how to access a Professional 350/380 (RSX-11) disk from VAX/VMS?

The cabinets in the background are probably part of the VAX 8600 setup I think. I did not have a closer look back then, because I was busy to get my VAX-11/750 (rather one 80% complete VAX-11/750 and two rather desolate and almost empty 750s) out of there. These are two of them on my horse...

I wish I had one, but I haven't (yet) ... Have you got a plan what to do with yours? I'd like to use it for DDCMP synchronous serial networking, e.g. in conjunction with my DSV11 (operational in a MicroVAX 3300) or my DMC11 (untested, planned for usage in my VAX-11/750 (still under...

Has any one got the EK-DEMSA-RM-001 DEMSA MicroServer Manual (or any other revision)? There are two links on Manx, but both are broken, and Google doesn't know either ... And if anyone had a MicroServer to spare in Europe? Postage from the other continents would be rather expensive. Ulli

Still interested in the DECnet End Node key and other MicroVMS Software? I can help!

The MULTI-TREK/VAX game is available again now! You find the complete kit (VMS V3.0, FORTRAN V2.4, MTREK Sources & MTREK compiled & linked programs & MTREK manual) here.

DECnet Rainbow seems to be available here: https://oldcomputers.dyndns.org/public/pub/mirror/os2site/sw/dec/rainbow/msdos/decnet/index.html And I found a helpful manual (more than the title promises) in my collection:

I'm not a Rainbow specialist, but I know there's "DECnet DOS" (e.g. here). As I'm experienced with VAX/VMS I know that DECnet over serial lines was rather common from VMS V4.0 onwards, sometimes called "Poor Man's DECnet", because you do not need an expensive Ethernet Adapter. So if there's a...

Removing the comment and recompiling/relinking results in: $ MC MTREK Welcome to MULTI-TREK. The following vessels are available for use. Ship 1 Ship 2 Ship 3 Ship 4 Ship 5 Ship 6 Ship 7 Ship 8 Enter the number of the vessel you wish to command:1 ...

I used: C EXTERNAL SS$_NORMAL,SS$_ACCVIO,SS$_EXQUOTA,SS$_ILLEFC *,SS$_INSFMEM,SS$_IVCHAN,SS$_NOPRIV,SS$_UNASEFC,SS$_ABORT *,SS$_INSFARG,SS$_ILLSER TYPE *,' SS$_NORMAL =',%LOC(SS$_NORMAL) TYPE *,' SS$_ACCVIO =',%LOC(SS$_ACCVIO) TYPE *,'...

Have a look at the manuals. Unfortunately the relevant manuals for VMS V3.x are not available, but I'm quite sure there's not much of a difference. Ulli

It depends on your choice when you choose the vessel. a) If you choose a vessel not chosen before, TIMOUT=0 b) If you choose a vessel already chosen before, TIMOUT=-1 I saw that only now. The following vessels are available for use. Ship 1 Ship 2 Ship 3 Ship 4 Ship 5 Ship 6 Ship 7 Ship 8 Enter...

Next round: I modified INPOUT.FOR so that: ... EQUIVALENCE(TC, IOSB(3)) CV DEBUG TYPE *,' IOFC BEFORE=',IOFC CALL FLUSH(0) IOFC = %LOC(IO$_READVBLK) .OR. %LOC(IO$M_TRMNOECHO) CV DEBUG TYPE *,' IOFC AFTER1=',IOFC IF (.NOT.(.NOT.ECHO)) GOTO 2100...

That's what the DEBUGGER tells me: DBG>g routine start at YESNO routine break at INCHAR DBG>g routine start at INCHAR write to INCHAR\IOFC at PC INCHAR\%LINE 14 +14 old value = 0 new value = 4145 DBG>g start at INCHAR\%LINE 15 write to INCHAR\ISW at PC INCHAR\%LINE 25 +35...

Citation from: AA-Z501B-TE VAX-VMS System Services Reference Manual V4.2 "Programs should not test for success by comparing the return status to SS$_NORMAL. A future release of VAX/VMS might add new alternate success codes to an existing service, causing programs that test for SS$_NORMAL to fail."

Good morning, these are my results for INPUT, SIZE, ECHO, TIMOUT, COUNT, IERR, and ISW (result of SYS$QIOW): DBG>EXA INCHAR\INPUT; EXA INCHAR\SIZE; EXA INCHAR\ECHO; EXA INCHAR\TIMOUT; EXA INCHAR\COUNT; EXA INCHAR\IERR INCHAR\INPUT(1): 0 INCHAR\SIZE: 4 INCHAR\ECHO: -1 INCHAR\TIMOUT: -1...

It's getting late - I'll get the values you want tomorrow. Where did you get your programming skills from? Thanks again!!! Ulli
