I have migrated from Netscape 4 email, all the way to Thunderbird3, and
never had a problem with moving the mailfiles. I don't know the details,
but the mailfile format hasn't changed.
I've recently opened some mailfolder from Netscape 4 directly in TBird
2 without a hitch.
I'd suggest going to 2.0.0.24 (or whatever is the most recent version
of the 2 series). I tried TBird3 here at work, and didn't like it for
the way I use it at work. The message folder search function to be specific.
But TBird3 works good for me at home...

Well, I was thinking of adding in that if you have a really old modem
you might have to flip the originate/answer switch appropriately if it
has one, but I think the OP indicated he was dealing with later stuff.
(I have a couple of pre-'smart' modems, too.)
--------------------Reply:
I was going to make the same point; the M100 he mentioned as an example
*does* indeed have an originate/answer switch (as well as a direct
connect/acoustic coupler switch).
I usually don't have any problem just connecting modems together without any
fancy line simulators, etc.

Folks,
OK, this is my DEC collection minus the machines I'm keeping, MINC
shipping is going to be interesting should anyone want it, see also
the DECwriter III. I should keep the DECmate III too really.
Most of these machines I used at work in the 80s/90s and rescued them
when I was made redundant in 2001, Grey Wall included. I'd hate to
recycle this as I've dragged the entire thing around the country and
would like to see it go to someone who hates reading docs online like
me :) Will I even pick up my VAX programming skills again and need to
know the params for the $QIOW routine :/

Hello listmembers,
some of you will perhaps remember me being stuck with a problem regarding a Fujitsu FANUC "mate TG" CNC controller (rebadged as "Siemens Sinumerik"), of which I have the main unit but not the monitor. Thanks to a very nice guy living nearby, I was provided with some new information about the interface, which is rather uncommon in itself. I had already guessed that there is a significant amount of smarts in the monitor; the newly acquired documentation confirms this. The silicon brain (CRT controller) of the thing is called LSI HD46505.
Integrated with a 12" monochrome CRT display, it features capabilities for a text mode with 64 columns * 24 lines (character size 7*9 dots in an 8*16 character cell), a magnified text mode with 16 columns * 14 lines (21*27 dots in a 32*27 cell) and a b&W bitmapped mode with a resolution of 512*384 dots. Text and graphics can be displayed alone or in combination. The supported character set seems to be a subset of ASCII from 0x20 to 0x5f.
Text and raster graphics operations in absolute addressing are controlled by a unidirectional 12 bit parallel interface with strobe (AB0 - AB2, DB0-DB8, WP) in differential signalling, furthermore there are four more differential signals called +HP2, -HP2, +VP2, -VP2 that allow some kind of incremental (relative) graphics cursor positioning by pulse trains. The signalling diagrams indicate a minimum cycle time of 20 us for the parallel interface and 110 us for the counter channels.
Does this ring any bells with anyone? Are there similar monitors out there that might be converted with little effort? Otherwise, the registers and instructions are described in enough detail so that making a replacement or some sort of emulation at least seems possible. What sort of hard- and/or software would one be looking at to accomplish this?
I have some hazy memory of seeing a demonstration of a Pong game programmed in LabView(!) running on an FPGA based device which would directly generate VGA output, but that was a very expensive unit. For now I'm just looking for a cheap and simple way to give me some idea of what, if anything, the controller is trying to display.
As I think the data will be coming in bursts (only e.g. when a new screen mask is displayed), a microcontroller with a suitable amount of buffer memory might be sufficient to translate the interface signals into serial data and send them to a PC, which would then generate and display the image.
Thanks for your input, yours sincerely

I aquired a lot of small DIL14/16 PROMS ceramic package with a 8 digit
number on it some of the numbers are :
2584 0821
2574 6975
2571 5418
2600 1529
1447 3581
1447 3540
2600 1495
1447 3797
2600 1487
2603 2623
2625 5562
2554 0888
2600 1495
I can't find any reference about them, so if some one recognizes the numbers
or can use them let me know (I've a few hundreds of them)
If no one wants them I'm going to archive them in the big metal bin.

Hello guys,
thanks for your quick replies!

You're joking, right? I don't even get what this guy is writing about in most of his half-finished malformed sentences. Even if he was willing to help, it might be quite a challenge to get anything useful out of him.

That's provided in that latest manual I got, down to bit-level detail, e.g.:
"Mode selection:"
A A A D D D D D D D D D
B B B B B B B B B B B B
2 1 0 8 7 6 5 4 3 2 1 0
-----------------------
0 0 1 1 x x 0 1 1 x x x Set bit mode*
0 0 1 1 x x 0 1 0 x x x Clear bit mode*
0 0 1 1 x x 1 1 1 x x x Enable drawing by +/- H/V inputs*
0 0 1 1 x x 1 0 1 x x x Clear screen (takes approx. 40 ms)
Operations marked * are latching and clear upon next selection."
Pages and pages of such codes.

No, I never learnt either of the above. OTOH, some LabView programming once again would be a nice change, and there is that FPGA toolkit for it that we were shown then.

Hey, that also sounds seriously interesting. Might be the cheapest and simplest approach since b&w doesn't need much of a DAC or anything. Alas the raster size doesn't map nicely to TV standards...
I'm also still all ears for comments on the "uC preprocesses, PC displays" idea.

This mode is not used here, the manual states that this display is non-interlacing.

Googling online. Also have a share certificate. Did you find out any
info. On GRI? Just want to know if I'm a millionaire and have been
living life as a peasant
Sent from my iPod
I recently got my hands on a NEC Advanced Personal Computer. From what
I read, it's a MS-DOS and CP/M capable machine. It's got dual 8" drives
and about the size of a terminal.
With that said, anyone have any more information on this system?
Anything to boot it perhaps, and of course, the unit I have didn't come
with a keyboard, and the connector appears to be some type of centronics
connector. Any suggestions on where to find such a beast?
