Are there any other PDP games that people have or can remember? We
definitely played more than just SHARK ATTACK but I don't remember any
others and my friend is also coming up a blank. Source code would be
great - I can probably port to VAX/VMS if required.
We are due to have two restored ASR33's coming to DEC Legacy, it's
definitely an opportunity not to be missed!
MTREK? That is a multi-user Startrek game for RSX. Probably not useful on an ASR33 though. I think I have a Pac-Man and some other video games as well. Also not very usable on an ASR33. :-)
And we obviously have ADVENT and DUNGEON. Just look through old DECUS catalogs.
Or just run through "101 Basic computer games" by Dave Ahl. He's an old DECcie, who wrote that book while still working on PDP-11 systems.
As for more modern stuff, I have a Z-machine emulator, so you can play pretty much all Infocom games on RSX and RT-11. I don't think it works on RSTS/E at this point, simply because noone went through the effort to write the bits to get it working there.

You mean the bus jumpers? No (those are hard to come by - sorry!). It
doesn't even have a chassis or power supply - it's just the backplane.

I'll look around. Somewhere I have some of thee soft-font files. There
were a number of them that DEC/DECUS produced such as Cyrillic, Hebrew,
and even an upside-down and backard ASCII set.
As I'd said, I knew that I had them here somewhere; however, I had to resort
to a disk search as Google didn't help me much. You can find several of the
soft-fonts I spoke of, and more, here:

Many LK-xxx keyboards
I have a VT501 but no keyboard for that (LK201 has the wrong plug). Do you have something compatible?
Did you mean a VT510 Paul?
I assume you know that a normal PC keyboard with a PS/2 connector works?
You don't get all the right keys, but at least you can use it.
If be meant VT510, he's looking for an LK-46W-A2.

I came across this little gem when perusing VT220 escape code:
"4.4.2 Designating Soft (Down-Line-Loadable) Character Sets
You can define a soft character set (font) that may or may not replace =
one of the existing hard sets (ROM fonts). If you do replace a hard set, =
the replacement occurs for both the 80 and 132-column versions"
Does VMS support this? Or is it up to the terminal emulator?
Of course VMS supports this. All that is needed is to send a series of
properly formatted escape sequences to the VT220.
Back in the early 1980s, I used this feature to turn the US Navy's VT220
terminals being used with the DATCP HITS (Digital Automatic Test Program
Generation Hierarchical Integrated Test Simulator) I was developing into
a data scope. You used these soft-font in much the same was as the DEC
Line Drawing sets. You load the terminals GR (Graphic Region) with the
soft-font set with an escape sequence and then, subsequence ASCII codes
will cause the font in the selected graphic region to be displayed. The
terminology DEC used for the format for depositing these character sets
was SIXELs.

Actually this looks like a nice clean solution that is by default extensible in Python.
I think I'll start with SIXEL and add ReGIS later.

How to paint any kind of graphics into Terminal.app windows are beyond me. But if you want to play with soft fonts, or sixel graphis (or ReGIS), you need to intercept the incoming byte stream to Terminal.app, and then interpret that stuff to pull out what you are expected to display.

That was going to be my basic approach, write a little shim that looks for control chars and if it sees ReGIS/SIXEL it draws a canvas, otherwise it passes it along to Terminal.app..
Some guys did with PNGs and JPEGs in Python, this could be fun..

To point out a few (maybe obvious) things.
Sixel graphics is not the same as soft fonts. Soft fonts are defined in a very sixel-like format, but you cannot get a sixel graphics image and display it on such a terminal.
I was just going to paint the bitmap canvas into the Terminal.app window, that should work right?
Not sure what you mean here. Sixel is a bitmap format. On pixel per bit. Six bits per byte. Each group of six pixels are done vertically, but the stream of bytes are done horizontally. So you get one band six pixels wide at a time. If you want to do colors with sixel you need to do several passes. Each pass do one color.
The VT330 and VT340 were the last terminals who could deal with this. Obviously a lot of DEC printers also did sixel graphics.
The soft fonts on the other hand defines characters. You can have a maximum of 96 characters defined. So that is one limit. Each character however, can look any way you want. The software that converts gif for a VT320 finds common patterns to decide what characters to define, and then use those characters to paint the picture. So there are obviously going to be imperfections in the picture when viewed on a VT320.
