To: H19-PEOPLE at MIT-MC

I have just received some literature describing a new ROM set for the
H19 terminal. Features are as follows:

-Definable scroll area (2-25 lines)

-Complete <TAB> facility - The tab stops can be individually set and cleared
 or set at fixed intervals. The back-tab function returns to previous stop.

-Clock/Calendar - Time and date reported in ASCII and cycling automatically.

-Alternate character set capability - Supports character generator ROMS
 containing 256 characters. The extra 128 chars. can be simultaneously
 displayed with the standard set.

-Transparent mode - Each of the possible 256 codes displayed as a unique
 character.

-Hardware (CTS:RTS) handshake or standard <XON>:<XOFF> handshake

-Slow transmit mode - characters spaced apart to prevent overrun at
 high baud rates

-Light pen support

-VT-100 emualtion

-Reliable operation at 38K baud.

There are a few more features the sales blurb describes as well. This sure
sounds like a winner to me, but bear in mind I have not seen these ROMS in
action and this is therefore not a recommendation! I hope to get hold of a
set in the next few weeks and will report at that time.

The price for the firmware is $50 and is available from:
		Extended Tecnology Systems
		1121 Briarwood
		Bensalem, Pa. 19020

I have taken the plunge and parted with $49.95 for the new "Super-19"
upgrade ROM for the H19. See my previous message to H19-People
for preliminary details. My spies at the recent HUG convention in
Chicago assure me that this is indeed a real product and looks like
it is well worth the cost. There was considerable interest in my
forst message, so I will be sure to report as soon as I have the beastie.
I have also obtained a file containing all the escape codes (original
and enhanced) and will upload the file to MC when I can report some
concrete information. Extended Technology Systems is obviously a
garage operation (George Deffendall is the person in the garage!)
but nontheless I am very optimistic that the enhanced H19 will be a
terrific package.  Charlie Strom

I have been using the Super 19 enhanced rom for the h19-z19 terminal for
about a week now and have yet to note any problems. For those who missed
my first message, this is a replacement 32K rom available from Extended
Technology Systems, 1121 Briarwood, Bensalem, Pa. 19020 for $49.95 post-
paid. The phone is 215-754-4604.
There were several queries re the VT-100 emulation mode. I am not a DEC
afficianado, so I can only report that the documantation states that EDT
operation is greatly enhanced compared to the old VT52 mode using the VT-100
mode. All features are implemented except for slow scroll and character
size change.
I have also used the clock/calendar without a hitch (note - no battery
backup, though one might add it), the slow transmit mode at high baud rates
(characters spaced apart to prevent overrun at other end), transparent mode,
etc. Feel free to query me re specific areas I have not covered.

From what I can gather, all the H19 functions are alive and well when
in VT-100 emulation mode. This would presumably include both delete

I have been using the super19 rom for about a month now; note that
heath will be coming out with their own enhanced ersion shortly; it
will not have as many features but on the plus side the source will be
available.
The shifted function keys are a nice touch and enable me to run a
version of Wordstar using the numeric keypad (in shifted mode) and the
function keys to perform most of the operations. I am using the 25th
line for labels for the function keys but may use the 24th as well
(the rom allows as many lines as you want to be inaccessible a is the
25th under normal conditions.) I also use like the option of changing
the cursor to a solid underline, a slow blink, etc., depending on my
mood or the phase of the moon. The slow transmit feature (characters
are spaced out so as to prevent UART overrun on the other side) is
another useful touch.
I have not noted any bugs though I have benn told by a Heath expert
that there are some minor (unspecified ones). I do seem to lose synch
every now and then for a few 10's of ms. it seems, but I do not know
if this is related to the super-19 or not. I also had to give up
running at 19.2K baud; the terminal will overrun its buffer under
certain conditions and it got too annoying. I understand if I were to
modify the h19 to run @ 3Mhz, it would cure things, but I haven't a
clue as to how to do this since my machine is a late version sans
jumper areas for this purpose.

From: bridger at RAND-UNIX

	Thanks for your report.

	What are the possibilities for adding an alternate-page memory
buffer to the h19 that could be combined with the transmit-page feature?
Jeffrey Stone recently pointed out the utility of using this as a local
notepad that can then be printed or filed if desired?

	I find 19.2Kbaud a real plus when using a full-screen editor or
simply TYPEing a text file.  With the 3MHz jumper modification I get good 
results.  Is anyone running the super19 rom in this configuration?

However, I am getting snafus with an interrupt-driven real time clock that
is set to display on line 25 once a second.  Occasionally the cursor will be
left on line 25 after updating the time display.  The next text then gets
scrolled on line 25, a real loser!  Or,  one of the cursor addressing
characters will show up on the screen on the line that was interrupted.
Possibly the time-updating routine needs to do some padding before
returning; I haven't tried that.  Does the rom-clock develop this sort of
glitch?

	It works very nicely with EDT v.2 (& therefore, I assume, with
	KED) in VT-100 mode.

	It even has some adavanced video VT-100 features, such as different
	cursor form (eg, underline) & cut&paste buffer identification
	(eg, local reverse video).

	The sfw whitescreen seems to suffer more from tearing than the
	hardware mod, altho Bob Todd of ETS (the distributor) tells me that
	the hi speed mod will cure it. But then it would presumably also
	improve	the hdw whitescreen, too.

	The ability to Hold Screen Scrolling locally is very nice, since
	Hold Screen mode does not work for VT-100's in RSX.

	I am willing to check out KED specifically if requested --
	I'm sure I can dig out an old tattered copy at work.

	sideways scrolling seems to help get around the 80 char. screen
	limitation.

Subject: Interrupting CONOUT with CONOUT => lost data?
From: bridger at RAND-UNIX

	I've been using a clock/calendar that interrupts once a second and
calls a service routine that sends the current time to the bottom right
corner of the terminal screen.  To do this it sends escape sequences to
save the cursor, position it, and restore it.  The characters are sent
by  BIOS calls to CONOUT.
	Randomly, the terminal would print the time but then fail
to restore the cursor, or switch into reverse video or some other mode.
Things got worse with a new terminal rom (the Super19 ROM for the Heath
H-19) running at 38.4K baud, because this rom has a host of new
escape sequences for extra modes, some of which reinterprete the 
standard ASCII characters.  Having the terminal suddenly in never-never land
is a real pain; to recover you have to go into off-line mode, and reset
the correct modes.
	It turn out that the BIOS is sending characters to the terminal
when it isn't ready to accept them.  At least one gets lost; when the last-
arrived character is an Escape, and its successor is overtaken by another
character, the terminal switches executes a faulty sequence.  For example:

	'ESC k p' --  'ESC k' is restore cursor, 'p' is data
	If 'k' is overtaken, the terminal executes 'ESC p' = reverse video !

	My CONOUT implements hardware handshaking, using the H-89's
8250 serial chip.  I assumed that this, coupled with handshaking by the
H-19 terminal, would prevent dropped characters.  

	NOT SO!! -- because the interrupt routine uses the console output data
port the following sequence of events can and does occur:

	main program sends character to CONOUT
		CONOUT checks clear-to-send line:  it's clear
		now clock interrupts
			saves registers
			clock routine sends a string of characters,
			   filling the terminal buffer
			terminal turns off clear-to-send line: not clear now
			restores registers & returns
		  character sent to terminal (!!)
		  returns to main program
	
	In other words, the real-time status of the CTS line changes from
the time CONOUT reads the line to when it outputs the character.

	Solutions: (1) disable interrupts before reading CTS, enable after
sending the character; have the clock routine use a private version of CONOUT
that doesn't enable interrupts.  (2) Set a flag on entry to CONOUT, reset it
on exit; when flag is set have the clock routine poll CTS until clear before
returning.
	This complexity wouldn't arise if the 8250 had on-chip handshaking
(like the Z-80 SIO) and didn't send out a character until the CTS line
is clear.  I guess the moral is not to trust an interruptible handshake!

	My suspicions that the Super19 ROM was at fault were unfounded, and
I appreciate the time Bob Todd at Extended Technology Systems took to check 
out my questions.  It is indeed a high performance addition to the H-19.
With hardware handshaking and 38.4K baud, text can be redisplayed and edited
very effectively.  
	Now I'm curious to see what the game writers can do with it!

Pin 9 of U502 is connected to pin 3 U512.

Any suggestions for tests?  I have noticed that U502 is a 7492 as opposed
to a 74LS92.  I don't have diagrams of either, so I can't tell whether
that would make a difference.

All help greatfully accepted and appreciated!

	The vendor is Extended Technology Systems, 1121 Briarwood, 
Bensalem, PA 19020.  Telephoning is sufficiently worthless that I 
threw away the number, so write them for some literature.  It is a 
single chip replacement in your H19 which adds all sorts of bells and
whistles -- realtime clock/calendar, light pen support, white backround,
split scrolling regions, all VT100 effects except double-sized characters
and smooth scroll (incl. a better use of the special function keys to 
get all the desired EDT effects).

To: H19-PEOPLE at mit-mc

  Ok, I just got done putting my new super19 rom in my h19a, and have
found a problem (I think) and I thought I would drop this one on the
net and see what you folks have to say.
  Everything works fine, except when I use VT100 mode on our other vax
running VMS.  It seems when I run programs which use VT100 graphics, 
the characters are not correct.  I realize the documentation says that
'wide characters, smooth scroll, 132 char line, and on board LEDS are
not supported', however it says NOTHING about any problems with the heath
versus DEC graphics characters.  Does anyone know of any problems, if
so how are they patched, OR... is my Super19 rom perhaps munged? Although
the latter seems a bit odd, since the rom has nothing to do with character
generator rom, at least not in any way I can see it causing this problem.
  THanks in advance for any help I receive.

  Of other note: I too have received my H100 system, although minus the
controller board, *sigh*. After looking it over, it looks very nice, 
and I also have the extra floppy, extra 64K and the color chips and 
monitor.  It is a very nice kit, and of course very well documented.
I plan to have a BBS system up and running as soon as I can on this beast
and if anyone is interested, I will give them the phone number to dial
in.  I am working on my own version of a unix look-a-like which will
run UNDER cp/m-86 as EUNICE runs under VMS.  So far it is about 80%
complete (although not fully debugged since the code is being written
on a cp/m-80 system) I may also market this product for a small fee,
so anyone interested can contact me for more details on how it works.
