The VT330 and VT340 have the ROM cartridge slot, but for the VT330+ and
VT340+ it's all internal.

Re: [Simh] DEC VT emulators on MAME

[Timothe Litt]

The most useful thing for the VT500 cartridge is a RAM card, which
expands the page memory.

They were hard to get once the terminals group was sold off.  I managed
to get some, but they appeared to be hand-assembled - poorly.  But a few
minutes of reflow, and I was happy...

For the earlier terminals, the character ROM space was limited, so there
was a plethora of models that had various (pre-unicode) multinational
character sets and keyboard layouts.  Many of these were done by local
groups (e.g. outside the Maynard Terminals group.)  The keyboards
(LK201/LK401/LK421) were all identical hardware, but there was a
surprising amount of work involved in getting the dozens of key
labels/variations built/documented/manufactured.

Someone mentioned the VT180.  I happen to know that hardware quite well,
as I repurposed the module for something else.  It turns out that it was
a second re-purposing.  The board originated in the AD group - but that
group got it from an engineer who designed it for his model railroad.  
The floppies were another story...

You're describing this like there's a port on the external case of the
terminal for this, but I am not seeing that in the diagrams.  It shows
on the engineering drawings as a connector on the rear side of the
CPU module.



Am I missing something?

While we're talking about additional ROMs that need to be dumped,
there appears to be a ROM on the graphics board as well.

Oh, now I see, so ignore my previous email asking what you meant by
DS200/300/500.  I didn't realize you were writing DS to mean DECserver.

I know with X terminals you need more than what's in the ROMs to get a
functioning unit because they boot over the network.  Hopefully the
terminal servers aren't that complicated.  Maybe they just load a
config off the network, if anything at all.


All the ROM contains is enough code to boot using MOP on the ethernet. 
All the actual implementation of the DECserver itself is in the 
downloaded image. The DS200 image, for example is close to 200 Kbytes.

No. The VT330 and VT340 have an external cartridhe that plugs into a 
slot in the back, and which holds most of the code. The VT500 series 
also have a cardridge slot, but for those I've never seen any cartridge, 
so that must be some optional thing.

But for the VT330/340 the cartridge is not optional.

Is this in a place I can mirror it?  I'm trying to archive all the

I have always wanted an emulator for a DECserver 500! My ISP only hands
out 1 IP address so using NAT port forwarding to hang a DECserver off
port 23 would be really nice. I may have other uses for it too. (No, I
don't want a real one. I have enough stuff here.)


Seems like you are trying to find complex solutions for simple problems.

Wouldn't it be easier to just write some small piece of software that 
accepts incoming connections on the telnet port, and can let you connect 
to other things without having to emulate a whole DECserver?

Re: [Simh] DEC VT emulators on MAME

[Tim Stark]

Yeah. Later I learned that 'DC' means designed by DEC.  For example, T11 
processor is DC310. 

Unfortunately DEC did not publish VT300 series technical manuals so that we 
have reverse-engineer custom graphics processor for VT3x0 terminals.

He is reverse-engineering custom graphics processors for his VT emulators on 
MAME.  Only VT240 emulator is working but imperfect graphics.

Also, MAME has VK100 (GIGI) emulator but marked as not working.

Hi

I'd be interrested in this to.

It is quite a coincidence that this is brought up just now. I hade the 
idea this friday that I should try to emulate the vt220, seems I don't 
have to now.

Thank you,
Pontus.
