It's a firmware upgrade for bugs that were uncovered along the way.
If you hold the Cursor Left Arrow and Cursor buttons and power the
TZ's up, the display will show you what Rev. the ROM (PROM) is.
The current Rev. is 1.6, so depending on how old the TZ is, it could
go back to Rev. 1.0 (I think). There's a discussion in one of the
older TZ notes about earlier bugs and Rev. changes. I posted this
new, hoping to get an immediate response, not knowing who might
check the older note or when. In all honesty, I'm not sure what
the bug fixes are but they've certainly been discovered.

Im not sure why I know this, but....
(well, *I* am, but you're not)
Rom versions 1.0 to 1.5 were shipped from Yamaha.
Version 1.6 fixes some obscure bug (read: no one seems to
know, and Yama isnt telling, and have *YOU* found it?)
Version 1.6 was never shipped INSTALLED in a unit. It is
availible to fix that elusive problem with 1.5....um,
what did you say that was again?
It seems that Yamaha is taking "well, if you havent
run across the problem, and cant tell us what it is...
why do you NEED the update?"
I think that's the rationale around trying to support
their local service organization, and have those folks
upgrade your 81z, not you. (Ie, you get charged lots to try
it yourself...). If it works, dont fix it...that thing, ya know?
NOW: ALMOST ALL 81z's have the rom chip in a socket, so
upgrade means taking off the top and swapping chips..with one
exception: A FRACTION (not all) of Version 1.5 Roms are soldered in.
Ok, now THEN I could see charging for some time to change it...
But the odds are with you...but what are you trying to fix?
Your fellow 81z enthusiasts would like to know!

| 2304.4 | No known bug reports here! | WOODRO::KMCQUADE | | Wed Apr 11 1990 16:41 | 20 |
| Fellow 81z enthusiasts, it is not that I uncovered the phantom bug, I
was just aware from note 761.* that there was a ROM upgrade for the
unit. My ROM was a couple of Revs back and when I called Y they told
me the latest was 1.6 and then gave me a list of no longer existant
service locations where I could have the installation done.
I was hoping someone might have gone thru this recently and could point
me to a place where I wouldn't have to pay a hefty charge to have them
take out 7 screws, pop the top, remove a socketed PROM and put in a new
one.
Sorry if I left the impression that there was a bug and I knew what it
was and was not relaying that info. If that were the case I would
certainly have announced that fact.
In this case, I guess I will get a defacto Rev. 1.6 upgrade just
because I knew, thanks to this notes file, that there had been a number
of ROM upgrades along the way.

| 2304.5 | Any Update ? | HAMPS::POORE | Stuart Poore, IM, STG, @BST, U.K. | Tue Sep 11 1990 11:06 | 8 |
| Does anybody have an update on this ?
I just bought a S/H TX81Z and it gave version 1.3 .
Is it worth the aggro of trying to get 1.4 , 1.5 or 1.6 ?? Is there
anything major wrong with 1.3 ?

| 2304.6 | Save your effort... | DCSVAX::COTE | To play, turn bottom up... | Tue Sep 11 1990 17:27 | 7 |
| I've got a V1.3 and a 1.6. I've found no difference between them, the
possibility of a soldered ROM (vs. socketed) in the earlier version
being the only exception.
I'd put no time or effort into seeking an upgrade to the ROM.
