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 that I've done any OS X development to speak of.

Yup, I converted some GIFs using NETPBM to Sixel graphics.
I wish there was a Mac or Windows terminal emulator capable of showing them..
Did you checkout VTstar? That runs on Windows. Although I'm not sure of the latest version it will work on. I believe it works with Vista. Here is the link anyway:
Sadly it doesn't work either. I'm tempted to write some kind of shim that would capture ReGIS / Sixel escape sequences and draw them on Terminal.app.
The protocols are pretty simple.

The soft fonts do indeed differ between the terminals. There are some limited backward compatibility between them, but that is best left alone. The differences are pretty much just a question of different resolution, or size of the character cell if you want to put it that way.
Also, I think a couple of extra parameters were added to the escape sequence along the way, but nothing really significant.
The OS do not really have to do anything in relation to this. It's just like any other font on the terminal. You can switch between them using escape sequences, and the OS is none the wiser.
I've designed fonts for pretty much all VT models, in both 80 and 132 column format. I did this for the Z-machine font, which I used with my Z-machine emulator when playing Beyond Zork.
And so, yes, I have a font editor. This have been mentioned before on the list. It can be found at MIM::DU:[FED]. Written in C (not by me originally], converted to DECUS C, and adapted to handle most VT models. Free to play with if people want...

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.

Hello!
Bob how big is the DELNI? And the DECserver-100? I am always
interested in new gear.
Those are both 19 inch rack devices, 2 or 3 U, forgot which. Not very deep, less than 19 inches as I recall.
They can both be rack mounted, but the default for them is to be standalone. But the outer plastic shell can be removed, and brackets attached.
If someone wants to get a picture, just search the net. There are plenty.
The DELNI and DS100 are the same height and width, but I'm trying to remember if the DELNI isn't even shallower than the DS. They are both way less than 19" anyway.
They are both pretty light. Mostly air inside.

I have a Dec Server 300 coming and want to put some mmj sockets in two rooms. Does anyone know where I can source these?

If you're looking for real world examples then Google is your friend. There is a program floating around that converts gifs to sixel graphics that can be displayed using the soft character set on VT320 terminals.
Regards, Tim.

I wish there was a Mac or Windows terminal emulator capable of showing them..

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?
Here's the link: http://vt100.net/docs/vt220-rm/chapter4.html
That stuff generally needs a real terminal to work. As Julian pointed out, there are some emulators that do support this feature. I believe the VTstar software might do it, although I can't confirm that right now. The DECterm terminal window doesn't support it, that is the only way I think VMS could support it given it is a feature of the terminal. I'm pretty sure (it's been a while since I played with this stuff) that the soft character set is not the same on different models of terminal either.

I'll have to look into that Mac240 software, sounds cool.

I just did a bunch of work messing with this. It works on the Mac emulator called "Mac240" for 68K machines, which also emulates ReGIS graphics. I would have no idea what VMS would 'support', but it's just a matter of dumping escape code sequences to the terminal.
I have been unsuccessful at getting a real 220 to respond to the escape codes that the Mac emulator seems to accept, according to the VT220 programmer's reference.
