Looking at the logs, it's not trying to define the font bitmaps, and it's drawing text using command 88h. Hypothesis: that font is assumed to be defined by the IM1024's ROM and doesn't need loading with TDEFIN. Therefore letters only get drawn when the software rendering path is used (for example, for greyed text).

So first task is to get the bitmaps out of VMILO.FON and into PCEM...

freetype doesn't like VMILO.FON, so how to extract font bitmap from it?

I used PSFtools (and had to fix a bug in that, so you need psftools-1.0.12).

Code:
fon2fnts vmilo.fon
fnt2psf Terminal_12.fnt | psf2raw > im1024font.bin

Probably not - the Windows 1 Premiere Edition installer hangs if it encounters a driver other than the ones it came with.

It may work with 1.xx, since that has a better setup that's closer to the final, and the overall system is near final as well.

Tried on 1.xx and it works fine.

More information would be welcome. Which emulator (and build of it), which version of Windows 1.0?

- ComputerHunter: Did you use John Elliott's instructions above to convert VMILO.FON to the binary file the emulator needs?

I got an insufficient disk space error when using the binary file. Do I replace LOFONTS.FON with it?

You need the font in two places:
* VMILO.FON replacing LOFONTS.FON within the Windows installation
* VMILO.FON converted to im1024font.bin in the emulator ROMs folder.

Well, presumably you didn't convert the font file before using it as a ROM, since the characters are all subtracted like if an unexpected header was present.

I did exactly as mentioned above. What is the hash of the converted font file?

I can't get that hash, I am using the version 1.0.13 of PSF Tools. Is it possible to just upload that raw font?

Thank you very much, it works.

The copyright symbol in the About dialogue doesn't look right.

Judging by the fonts in VMILO.FON, the card character ROM used codepage 437, which doesn't include a copyright symbol, and so whoever designed the font mapped that character to ◙ .

'Terminal' font (CP437):

'System' font (CP1252):

I tried to recover as much info as possible from that Cobra driver disk. It looks like the floppy images is in good condition except for all root directory entries were zeroed. I managed to recover modification time and name for all directories and some files.

I can see a few interesting Windows drivers and I wonder which version of Windows they were designed for. I am suspecting Windows 2.x because I recovered a few font files in Windows 2.x format. I managed to recover COBRA.DRV and COBRA.FON but I didn't get the grabber file.

There is also an interesting application named DIAG.EXE which (I think) is for the IM1024. I tried to run it using the emulated IM1024 and it prints "DIAGNOSTIC ERROR 0". What does it mean? It is the problem with the emulation or it wasn't designed for the IM1024?

Using recover, chkdsk or scandisk to repair the disk results in clusters being mixed up and most files being unusable.

The Cobra driver is for Windows 2.x, yes. DIAG.EXE is likely for the Cobra too, as one of the text files suggests. In either case, if you combine mashed up files with the incomplete state of the IM1024 emulation, I don't see a scenario where things would work as they should.
