Hello, i have recently owned a HP200LX

The HP200LX is a PDA running DOS on a 80286 chip.

I tried to execute FASMD.EXE/FASM.EXE

a error apears: cannon execute FASM.EXE

whats wrong?

fasm requires a 386 class CPU or higher.

why does this need freaking 32 bit
cant they make a version of 16bit?
its sad for vintage stuff

"they" is actually Tomasz Grysztar You can write code for the 80286, with some caveats.

i would like to develop my stuff with my vintage device

and not only for it.

Go WASM (Wolfware Assembler, by Eric Tauck).

WASM v1.0 (a 19kb COM program):

In case you have problems downloading it from the sites above, just let me know.

thanks for the Reply patulinu

i will try this

I thought about recommending TMA as a replacement for fasmd (it is an assembler with built-in IDE that I remembered as a source of inspiration when creating fasmd), but then I found out that it also requires 386. I did not remember that detail.

So you are probably left with much older tools only. Note that when I was writing the initial version of fasm, 80386 was already more that ten years old.

On the other hand, when I started the fasm g project and was choosing whether to make it x64-only right from the start, I decided to stick to 386 instruction set. Even though it does not make that much sense when everything is implemented in form of macros that take ages to assemble unless you have a relatively new machine. But I kept in mind that I might want to make fasm 2 out of it.

Are you aware of Free Pascal 3.0.0 (which also supports inline asm), which now officially supports an i8086-msdos target? I think they also tested (somewhat) on an HP200LX. (This uses NASM and OpenWatcom's WLINK + WLIB, but those aren't necessary for trunk anymore.)

* ftp://ftp.freepascal.org/pub/fpc/dist/3.0.0/i386-linux/fpc-3.0.0.i386-linux.cross.i8086-msdos.tar.xz

But anyways, here's NASM 0.98.39, the last one to have an official 16-bit DOS binary (though not built supporting all output formats, of course):

EDIT: I forgot about JWasmR, which is the real-mode DOS version of JWasm, a MASM v6 clone:

There are 16-bit binaries of NASM: http://ibiblio.org/pub/micro/pc-stuff/freedos/files/devel/asm/nasm/0.98.39

FPC reportedly supports 8086 ... but only as target AFAIK ... I have no clue how far it still works on 80386 at host side.

I assume you already knew this, but ....

I'm still occasionally running 3.1.1 (Win32-hosted) FPC snapshots under HX in DOS since they have yet to make it officially DOS-hosted via GO32v2. I honestly don't know what the hangup is. Of course, that's not on an actual "386" machine, so I too don't know if it is compatible with such "classic" hardware.

There's also an assembler (DOS, 8086, only 8 kb, by Venkat Iyer) that can bootstrap itself:
