Hi,
I've been trying not to post random questions here, but I have to ask so I can decide if I should put this drive in storage or clean it up and buy a couple of tapes for it.
I have a Compaq DLT4000 series 20/40 GB tape drive (also known as a Tx88 in DEC parlance I think?) in an external cabinet (a big old lump) with HD50 SCSI ports on the back. It's a nice piece of engineering, very much still DEC-esque in it's build quality and no-nonsense construction.
I basically would like to know if it would be supported in either VMS 7.3 on a VAX or VMS 8.3 on an Alpha, and perhaps how to utilise it if it is. I am used to using 'tar' and 'mt' on UNIX but never looked at using tapes *inside* the OS on VMS.
My guess is that it will work just fine. VMS supports tapes over SCSI, and this is just another tape over SCSI.
As for how yuo use it, that is up to you. BACKUP can write backups to it, or you can initialize and mount it, and just copy files to/from it like any other device (well, not like any other, since tapes have some different characteristics, but it will pretty much work as you would expect). DIR works on such tapes, but you cannot delete files, nor modify existing files.
Or you can just mount it foreign, and do whatever you want on it at a low level with your own programs...

I had heard that a significant portion of SMS text messages world-wide are
routed via VMS systems. I suppose it might be true since OpenVMS seems to be
used for mobile network infrastructure.

Nice example of VMS still out in the wild...

Hello!
I knew that. I also know that there are a substantial amount of
systems being employed to do strange things.

Are the shelves blue or grey? Can you give me the model number of the shelves? Sorry for being picky, I need the ultrascsi versions...
I'm planning on posting that modem off today.

I was talking to someone at the DEC Legacy event about the erosion of DEC kit in Universities and Colleges after Microsoft's anti-trust law suit the settlement of which required Microsoft to give away copies of Windows.
DEC didn't follow suit.
Ironic that an anti-trust settlement against Microsoft just ended up with more people running Microsoft software, which locked them into Microsoft upgrade paths.
The same irony of Linux as the supposed 'free and open UNIX/-derivative'
doing the bidding of UNIX against Windows, where in the end Linux almost
exclusively destroyed perfectly good proprietary UNIX distributions (think
of IRIX) on the basis of alleged cost reduction, with Linux in the end
still mostly in the fringes and server niche, just like on day one.
(No, I don't consider Android a proper Linux. It's far too customized and
intertwined with proprietary supplements to be truly considered Linux. It
is not like people consider Mac OS X a typical BSD in that sense either.)

BLISS-11 was also a differently language too, albeit slightly. When DEC
adopted BLISS they just had to change some of the syntax to make it their
own.
Likewise there was a BLISS-10 and a BLISS-36. And there was a BLISS-32
for VAXen, although AFAIK there was never a cross compiler for that version
and there was never a BLISS-10/11 equivalent for it. BLISS-32 was of
course used fairly extensively for VMS.

Bliss36 and Bliss32 for vaxen is different than bliss10.. The 32/36 compiler
is the same compiler with different backends..
Hmm. Are you saying that Bliss-36 ran on VMS?

I've been offered a very nice printer for the price of shipping. It's a
centronics based printer. I currently have an LA75 hooked up to a
DECserver 90M. Obviously MMJ/serial connection.
My question is - does OpenVMS support parallel printers? Would it be a
lot of work getting it to work natively without having to include
another box in the mix (ie, a linux box).
My brain has been trampled on with work today, something may come to me
yet...
Actually having said that, I guess a Centronics/Network interface would
do the trick at the very least.
The answer is yes, though.
But only for machines that actually have hardware parallel ports, such as Unibus machines with a LP11, or Q-bus machines with a LPV11.
No pizza-box VAXen, or more modern big models have parallel ports as far as I can remember.
(Of course I can be wrong...)
But even if you discover that such an interface exist, you also need to locate one to add to your machine in order to do this.
By the way, the LP11 interface is almost identical to Centronics. It's one signal (if I remember right), which have inverted levels, but otherwise it works just fine.
If you have a parallel interface, VMS makes it available as a device driver. The normal spooler tasks can make use of that interface just as well as a serial port. Makes no difference from the spooler task point of view. It's just an interface on which you send bytes.

I've got some sort of a hp inkjet thing plugged into my
Alphaserver 800. It shows up as LRA0: I've added a postscript
option board to the printer which works in principle but it
is a little fiddly getting the settings right to ensure the
printer doesn't interpret the postscript as text. I keep
meaning to investigate DCPS.
