I wonder if there is hardware/driver that makes Windows 1.0x running in 256 colors?

From some PC-World magazines, it seems that there is Genoa SuperVGA HiRes is able to do this, but I can't find any driver on the net.

Maybe if you could find ROMs and drivers for 86box. More about that here: http://toastytech.com/guis/miscc.html. You can do this with Windows 2.

There is a 1024x768 256c driver for 2.x for tvga8900d, sadly not for 1.x:

PC Magazine had a screenshot of the Vermont Microsystems Image Manager 1024 displaying Windows 1.0x at 1024x800x256 colours -- see http://toastytech.com/guis/misce.html

As far as I know, the driver isn't on the Net. Once it was, you'd then have to implement the IM1024 video card in an emulator.

(In theory it should be possible to write a 256-colour (or even truecolour) Windows 1.x video driver for a VESA video mode; the tools in the Windows 2.x DDK can generate drivers in the correct format. But you'd basically be writing the driver itself from scratch, and the API is not what you'd call straightforward).

The Windows 1.0 pre-alpha from November 1984 for Tandy 2000 also supported 256 colours. Look here.

for IM1024, there is IM1024.DRV in V1DSK.ZIP?

Interesting...
Code:
% strings im1024.lgo
LOGO
Microsoft Windows
VMI IM-1024 Driver Release 1.04
Copyright (c) Microsoft Corporation, 1985.  All Rights Reserved.
Portions Copyright (c) 1987 Vermont Microsystems Inc.
Microsoft is a registered trademark of Microsoft Corp.

That looks promising. And a check with a disassembler seems to confirm it: the GDIINFO structure near the start of IM1024.DRV has a version number of 1.0.

[Disassembles some more] The IM1024 appears to behave like a superset of the IBM PGC, with all the registers memory-mapped at C600:0000. So without firmware dumps, what an emulator writer would have to do is a high-level emulation, parsing PGC-style commands written to the controller and translating them into drawing operations. And work out what all the extra commands are that are in the IM1024 but not the original PGC.

One command I do recognise in the initialisation sequence is LUTINT 4 -- select an 8-bit truecolour palette (3 bits red, 3 bits green, 2 bits blue).

I've also run a quick scan over the other drivers in V1DSK.ZIP / V1DSK2.ZIP, and they're all mono, 8-colour or (in one odd case) 4-colour (SIGMA4.DRV). I wonder what that looked like?

The thing that is somewhat interesting is that the Tandy 2000 build has very high resolution (and large amount of colors it can display), which later versions don't have (I'm talking about Alpha, Beta etc). Later pre-releases seems to be downgraded to work on IBM PC and its clones without extremely high system requirements. Anyway, here is a higher resolution picture if anybody is interested:

I hope that this build will be leaked someday so we'll be able to test it out by ourselves.

I've also found this:

Looks like such hardware exists but finding drivers (and ROMs) will be at least very difficult if not impossible.

Edit:
Someone has such hardware:

I have an IM-1024 board. It came with two disks that may be what you are
looking for. The disks are hand-labelled as:
"ROOT DIRECTORY FOR RUNNING AUTOCAD V10 WITH VERMONT GRAPHICS ADAPTER"
and
"IM1024 COBRA (8BIT) UTILITIES DRIVER DISKETTE *DIAGS *IMDOS *VMDOS
*AUTOCAD9.x *AUTOCAD10.x *CADVANCE *CGI *CV *PCAP *VERSACAD *VDI *WIN286
VERSION 2.06 A0100x1"

I don't have access to a working 3.5" disk drive at the moment, but give me
a few days and I will make images available.

The Tandy 2000 version was probably developed separately to support color and thus make use of the computer's above-average capabilities. The PC version was never intended to support color for performance reasons, but they later changed their mind with the Beta, which supported color.

Also, if one takes a look at period magazines (1985-1988), you'll find plenty of ads and reviews for various cards, mostly VGA, which had drivers for Windows 1.0. Sadly, most of those aren't emulated and the drivers are gone, though I've managed to track down a few. ATI supported Windows 1.0 even with their VGA cards in 1989, for example.

yeah, but not 256 colors.
most win1 drivers in that time provides monochrome/4 colors/8 colors only.

Sorry, a 256 color driver for Windows 1.01 has not been created (yet). However, some drivers can be made for Windows 1.01 (I think).
