[Simh] More VAX Simulators

Ray,

That’s about what it takes on a real VLC. Its so slow. I just burn to an ISO.

I finally figured it out by setting console speed=300 on the simulator.  It is quite slow (takes about half an hour) but it works! ;-)

Thank you everyone for your advice,

Ray

The VTstar terminal emulator (for Windows and free) has some settings in the Options, Preferences menu, in the Timing button dialog.  I think you can probably work out the problem using that.

I tried doing a VMS 7.3 CD install on the 4000/60 and it went swimmingly until I tried to install the PAKs and I got this:

$!     
$!                            HPE HOBBY LICENSE AGREEMENT
$!           
%CREATE-E-READERR, error reading SYS$INPUT:.;
-RMS-F-RER, file read error
-SYSTEM-W-DATAOVERUN, data overrun

I am running 72 Megs and I do not get this error on 3900 or MicroVAX II.  I know there is another way to copy the PAKs over using an iso but the instructions in the Hobbyist letter seemed kind of fuzzy to me.  Am I doing anything wrong or is the the way a 4000/60 should behave?

Thanks

Hi Mark,

The first thing to note (if you haven't spotted it already) is that the
simulators have been merged into the Simh master branch and a number of
fixes have been applied. CD-ROM and tape drive support is now included
along with fixes to the memory sizing for the M60 and VLC.

The VAXstation 4000/60 and 4000/VLC are very similar so this simh.ini
will work for both:

; Set system memory size
;   M60 can be one of 8m, 16m, 24m, 32m, 40m, 48m, 56m, 72m, 80m, 104m
;   VLC can be one of 8m, 16m, 24m
;
set cpu 24m
;
; Attach the NVRAM device
;
attach nvr vaxstation4000.nvr
;
; Set the MAC address in the network address ROM
; This will need to match whatever your boot server is expecting
;
set nar mac=08:00:2b:40:00:60
;
; Setup local SCSI disks if required (here are a few examples)
; Also try 'help rz'
;
; set rz0 rz26
; attach rz0 disk0.img
; set rz1 disable
; set rz2 disable
; set rz3 disable
; set rz4 rrd40
; attach rz4 vms73.iso
; set rz5 tz30
; attach rz5 backup.tap
; rz6 is always disabled because this is the initiator SCSI ID
; set rz7 disable
;
; Enable LANCE Ethernet (device ESA0 under VMS)
;
set xs enable
;
; Attach Ethernet device to a host interface
;
attach xs eth0
;
; Start the simulator
;
boot cpu

The first time the ROM self-test runs after the memory size is changed
or after attaching a new NVRAM file it will perform a thorough memory
test. This can take quite a long time especially with 104MB. You will
see multiple selftest failures but don't worry about it, they're
expected for now. After the self-test completes I would recommend
enabling the fast boot option:

>>> SET FBOOT 1

This will significantly speed up subsequent restarts of the simulator.
Eventually I'll patch the ROM to skip the memory tests.

Assuming your boot server is all setup you can now boot from the Ethernet:

>>> BOOT ESA0

I haven't tested Ethernet booting on these simulators for quite some
time so I hope it works!

Let me know how it goes.

Matt
