Hi,

I just get a NSLab Color. Unfortunately, this unit have a v66 ROM. I
need a v74 ROM in it to work with my ADB SoundBox wich come from my
NSTurbo Color-and a v74 ROM-.

Does anybody have an idea if it's possible to get a v74 ROM somewhere,
or copying the v74 ROM of my NSTurbo Color on a fresh ROM ships. Or may
be someone have a v74 chip somewhere.


Thanks.

Jerome Vernet

So the colour slab is *not* a Turbo, right? Does it have the Turbo
chipset? (You can tell by the presence of the big Fujitsu ASIC; the
presence of this ASIC indicates that it does *not* have the Turbo
chipset.) Machines with the non-Turbo chipset do not have the
necessary hardware to run ADB peripherals.

No, it's not a Turbo, but a Color. Model No:N1200. Serial: ABC00090052.

There is some big ASIC, but seems to be not Fujitsu. Is it the big chip
near the Hard DRive ? It's labelled 'F JAPAN MB610313 9123 Y67 62.AC'
The Main board have a number: PN-2106.AB.

This main board is completely different from my NSTurbo Color. I have 8
memory connector on the Color, and 4 on the NSTurbo Color.

I read in the FAQ that to use an ADB SoundBox, the only problem is the
ROM version. So there is also a hardware limitation.... bad news...

I need a SoundBox non-ADB....

Yep, that sounds like the Fujitsu ASIC.


Definately a non-Turbo chipset machine.


That's my memory, at least. There's likely stuff in the archives
about this but searching may be tricky.

Thank you !
This should be added to the FAQ.

So, I cannot change the ROM of my NSColor to use ADB ...

If somebody have a non ADB soundbox -even in bad condition, but working
for the keyboard/mouse part- for me....

Here is the text:

To do ADB, you'll need
1) A CPU board with the Turbo chipset.
The Turbo chipset includes the ADB transceiver. Most Turbo
systems are 33 MHz 68040 boxes. There are a few hundred
systems with the Turbo chipset that run at 25 MHz.

2) A v74 or later ROM
This is the first production ROM that contains the code that
probes for the presence of the ADB keyboard. (I've run across
a few machines in the field that do ADB with v73 ROMs, but
these were pre-production 'science experiment' ROMs, complete
with bugs.)

3) A new cable.
The ADB bus uses a previously unused pin on the cable between
the Sound Box or monochrome monitor and the CPU board. The
newer cable adds a conductor on the previously unused pin. The
newer cables will also work with non-ADB equipment.

Cable ADB Old Non-ADB
NeXTcube 4534 150
NeXTstation 4535 1532
NeXTstation color 4536 2286

4) ADB sound card
You'll need an ADB sound card in your Sound Box or monochrome
monitor. These can be identified by the ADB jack (4 pins +
locator) used for the keyboard connector, and by serial number
prefix. Sound boxes manufactured with the ADB sound card are
series ADD. Monochrome monitors with the ADB sound card are
series ACX (going by the one sample I found!)

When using ADB peripherals with the NeXTStation Turbo Color, the
monitor vertical refresh rate is set to 72 Hz rather than 68 Hz. NeXT
switched monitor models when the ADB keyboard was introduced, and used
the keyboard type as a cue for what monitor was connected. When used
with a 68 Hz refresh 17 inch display, the only visible effect is a
slight distortion of the top 1/2 inch of the display. (Assuming the
hardware was OK before, of course!)

Well, this time, I have a NSLab Turbo Mono, with a v71 ROM. For what I
read, it can work with an ADB (N4000B) monitor, but I need the v74 ROM.
Does anybody have a v74 ROM chip ? Or is it possible to make a copy of
the v74 ROM from my Turbo Color ?

I found this at channelU:
TS-NEEPROM
NeXT Motherboard EEPROM upgrade - version selectable (ADB/Non) - burned
with your ethernet address

Is the channelU guy still active ?

I'm also searching for a non ADB Mono display 17", in France.... And a
non ADB soundbox, also.

I have a spare v74 ADB rom that is an original NeXT spare part and has an original MAC address burned in. Its availible should you want it. Let me know.

Thanks
