pcjs's Introduction

PCjs Machines

PCjs is the home of PCx86, the original IBM PC emulator that runs in your browser.

PCjs is also my homage to a small number of machines that I grew up with. Those machines include:

along with some hand-selected software, including some from my own personal collection, used here for archival/demonstration purposes only.

pcjs's Issues

PCjs Debugger doesn't support Carriage Returns across serial I/O to reset current line to first column

I figured out that my debugger application can connect to the PCjs Debugger window via serial I/O on the COM1 port. Details in https://pushbx.org/ecm/dokuwiki/doku.php?id=blog:pushbx:2022:1111_lcdebug_image_for_use_with_pcjs.org#comment_51a19d7eaf2539aa96ba0d557229eb0f

However, the application's line input handler uses lone CRs (without subsequent LFs) to reset the current line to the first column, ready to be overwritten by new content. This is not supported by the PCjs Debugger window which seems to interpret every CR as a complete linebreak, beyond only returning the carriage.

Can you start working on Windows 98 and later?

(WIP) Maybe port to WebAssembly?

We might need to port this to WebAssembly for better performance.

Apple

This isn't an issue, just a suggestion. I was thinking that it would be cool if there were early Apple PC simulations (Apple II, Macintosh), like how there is for Windows and MS/PC-DOS. It's just an idea. Thank you for considering!

Windows 95 RTM error CPU: Undefined opcode 0x0F at 0x00000001

I've tried the "Save Machine" link on https://www.pcjs.org/software/pcx86/sys/windows/win95/4.00.950/ and followed the instructions (paste the code into a html file and add the js file) but then when I go to the html file it gives me the error "CPU: Undefined opcode 0x0F at 0x00000001". Anyone know how I can go about fixing this.

Need machine with 8088 processor and Borland Turbo C ...

Hi, I need an emulated machine (by PCjs) with:

8088 processor
and 640kB RAM
and MS-DOS 3.20 operating system
and host keyboard,
And available Borland Turbo C disk images to loading at it.

Is there anyone can help me?!

PCjs is good, But it is very hard to config manually for individual purposes.

Qemu is easily configurable by entering its arguments in single command line to choosing available CPU model, RAM size, hard drive and so on. But PCjs is not configurable easily to choosing these.
Also PCem and 86Box is easily configurable but consume high system resources.

PCjs doesn't need hight system resources, But it is not configurable easily to choosing CPU model, RAM size, hard drive and so on.

Any idea what might be causing it? From what I can see the file referenced in the error does have the {% endraw %} tag. Does it interpret one of the characters in the file as EOF?

Save machine

I do not know if this is a current issue or not, but I am having a bit of trouble saving a machine and getting a state.json file. I found a blog post on the pcjs.org webpage https://www.pcjs.org/blog/2016/02/17/ that said I should get a file that contained a big chunk of Javascript code containing things like the state, machine.xml, ext. but when I click on it and input the file into <script src="pcx86.js"></script> and open the html file, the place where the screen would show up displays nothing but black. It might just be me and I do not yet understand how to use the save machine function but if someone could help me that would be great! Thanks!

MSWindows 95: Trying to start a DPMI program crashes the DOS window

Running https://www.pcjs.org/software/pcx86/sys/windows/win95/4.00.950/

We get an error as shown below, when a simple test program tries to enter DPMI protected mode. It reads:

MS-DOS Prompt

This program has performed an illegal operation and will be terminated. Quit all programs, and then restart your computer.

If the program consistently encounters problems, click the Start button, then select Help, Troubleshooting, and 'If you have trouble running MS-DOS programs'.

[OK] [Details>>]

The program encountered an invalid page exception.

Fault location: 0028:C0236811
Faulting component: DOSMGR(0E) + 00000ED5
Interrupts in service: None

Screenshot showing the error:

The dpmimini program is included in the disk image https://pushbx.org/ecm/test/20230813/bcdebugx.img which is unlocked on the server for use as a remote disk for PCjs. The source of the program is in https://hg.pushbx.org/ecm/dpmitest/file/845e876b561e/dpmimini.asm

If I run my debugger, lcdebugx.com dpmimini.com then on the first trace step (T command) it informs me that "DPMI entry cannot be hooked!" which is expected on MSWindows 4. However, tracing into the DPMI entrypoint (call far [bp + 00] instruction at offset 0143h) I get an address of FCB8:2F97 with the instruction bytes 63, 38 that disassemble as arpl [bx + si], di. If I try to trace this, the machine crashes in the same way as for running only dpmimini. The error message is exactly the same.

No IBM PC Logo image!

Please add the IBM PC Logo 1.00 disk image in the PCjs diskette list!

Windows 95 doesn't boot up.

1800's computer moment

Windows 3.1 through 95 RTM/OEM won’t install due to error [read comments]

The error is: WINSETUP.EXE caused a general protection fault at [RAM address {0001:FFFF}]

can't use while in school

hi it's me again i can access the website because of my school can you make a unblocked version of the website plz that will be much appreciated.

The content in the Microsoft Programmer's Library CD-ROM (1988) cannot be read normally on the emulator of windows 3.1

In fact, Jeff, this problem occurred on theMicrosoft Programmer's Library CD-ROM (1988)page in PCjs.org.

The following is the problem log:

The site where the problem occurred:
"Microsoft Programmer's Library CD-ROM (1988)"

Prerequisite:
I want to view the contents of the Microsoft Programmer's Library CD-ROM as described on the site. I installed the Microsoft Programmer's Library CD-ROM to C:\mslib.

Unsolvable difficulties:
After running C:\mslib\msl.exe, it displays

At this point, no matter I press any key on the keyboard, the program cannot continue to run unless I exit the program with Ctrl+C.

My OS:
windows 10

My Browser:
Chrome

Problem reproduction process:

Enter the The site where the problem occurred - Microsoft Programmer's Library CD-ROM (1988).
In the emulator, under win 3.1, load Programmer’s Library 1.0 (1988) on the CD-ROM displayed as Disk D.
Open the simulator, run D:\setup.exe, install Microsoft Programmer's Library to C:\mslib step-by-step following the D:\setup.exe shows
After installation, Run C:\mslib\msl.exe <---(Microsoft Programmer's Library installed above)
After running C:\mslib\msl.exe, it displays

The screenshot of the installation process is in the attachment, and the file name of the attachment represents its order

press “H”

press “Y”

After I encountered this problem, I installed win 3.1 via dosbox on my pc, but I couldn't install Microsoft Programmer's Library because it was not compatible with my CD-ROM. Few people on other computer forums know about pcjs.org and they cannot answer questions. At first I suspected that there was a problem with my keyboard, but when I pressed the button, the corresponding button in the "Keys" in the simulator also turned black, so it should not be a keyboard problem......

I just want to read the contents of each reference in the Microsoft Programmer's Library CD-ROM (1988) under windows 3.1, but I completely have no idea about what exactly should I do when the desktop turns this.

I’m sorry Jeff because I'm not sure if this can be called an issue, but I have tried various methods for nearly a month and no one worked.
I sincerely await your reply, thank you for your reading Jeff.

Mount supports only IMG disk images, not JSON disk images

Trying to mount the content of https://diskettes.pcjs.org/pcx86/sys/dos/ibm/2.00/PCDOS200-DISK1.json, saved to a local file.
Clicking "choose file" and then "mount".
Always getting "FDC: Unrecognized disk format"

Support keyboard.lock API

The navigator.keyboard.lock API allows locking the keyboard so that more keypresses go into the page instead of interpreted by the OS etc.

It's not supported by Firefox yet (and I don't know if it will be), so that might be a reason not to implement it. It would be convenient though, for e.g. the OS/2 1.0 Program Switcher needing Ctrl + Esc.

[Feature request] Add support for more formats and sizes of disks for mounting

I would like to run old programs I have archived here, and the mount feature is too limited. It doesn't support the .json5 format made by their own tool and only ingests .img files with very specific sizes. It would be great to have a cd-rom mount option that support disk images other than stick to the floppy disks sizes, as well as accept other image formats, like .dmg, .iso or even .zip files.

Using a german keyboard layout on Debian Linux / Firefox does not work well for some special keys

For example, I'm loading the default system (COMPAQ Personal Computer MS-DOS version 3.31) from https://www.pcjs.org/configs/pcx86/machine/compaq/deskpro386/vga/2048kb/machine.xml

I have a PS/2 keyboard connected to a Debian Linux 11-ish box, running Firefox "78.11.0esr (64-bit)" within a MATE Desktop Environment session. The keyboard has a german DIN T1 layout printed on its keycaps. (No Euro sign on the E key, but other than that standard.) In Debian I am using the "German German (no dead keys)" layout.

Some of the special keys do not work (on the DOS command line) as expected.

The first row (^ then 1 to 9 then 0 then ß and ´) unshifted works for ^ and the digits, but does not produce any output for ß and ´.

The first row with Shift produces nothing (° on the ^ key), !", nothing (§ on the 3 key), $%&?()+?~. This is wrong for Shift+7 which does ? but is supposed to be a forward slash / on the DIN T1, and Shift+0 which does + but is supposed to be a =, and Shift+´ is supposed to be a backtick not tilde ~.

The Ü key (next to O) and the Ö and Ä keys (next to L) do not produce any input, either without or with Shift, or with AltGr, except for AltGr+Ä which produces ^.

The + key (next to Ü) produces + without Shift, * with Shift, and tilde ~ with AltGr. All as it should be.

The # key (next to Ä) produces # without Shift, and double quote " with Shift (should be apostrophe/single quote ').

The punctuation keys ,.- next to M produce ,.- without Shift, ::_ with Shift (first key with Shift should give semicolon ; not colon).

The < key produces < without Shift, > with Shift, and | with AltGr. All as it should be.

AltGr+Q produces @, as it should.

Z and Y are correctly entered according to the layout. That is, the key between T and U produces Z, and the key next to X produces Y.

Entering the command keyb gr (from this COMPAQ DOS disk, or from the MS-DOS 6.22 first install disk) changes a lot of the special keys, but most are messed up too. Do you want me to map those out one by one too?

Is there an easier way to add a ROM to a 5160 machine other than what I'm doing now?

I have pcjs running locally. As a test I duplicated the BASIC ROM line in the corresponding machine.xml file - seemingly it also needed a different filename to be loaded - but that works:

So now I have:

<rom id="romBASIC" addr="0xf6000" size="0x8000" file="/machines/pcx86/ibm/5160/rom/basic/BASIC110.json5"/> <rom id="romBASIC2" addr="0xd0000" size="0x8000" file="/machines/pcx86/ibm/5160/rom/basic/BASIC110-2.json5"/>

I don't know if there's a market for it but I'd love a feature for loading ROM from URL/upload like there is for loading floppies.
Could I go about this in an easier way? Maybe without selfhosting?

Emulator

its not really a issue but how do i apply the emulator to my page i used this but it still wont work .-. i even added the extra command but it still doesnt work :(

Windows 95 Build 499 Doesn't work/install

Hi,

I tried to install Windows 95 build 499 on this page https://www.pcjs.org/software/pcx86/sys/windows/win95/4.00.499/ and the installed complains about a lack of space. The first issue is that it boots DOS 3.x which can only create and format a 32MB partition for C:. Then using the 6.22 install/boot disk to run fdisk and format the disk is still slightly too small for the installer. Can you make the disk bigger and make it boot from a newer DOS floppy?

Also is there and easy way to customize the machines on the webpage? Like if I want a bigger disk or more RAM. So far it seems the Windows 95 system is the biggest and I can't get it to reboot to a floppy for some reason.

How to compile PCjs in Raspberry Pi / Debian

Can you give me a guide on how to compile PCjs on Raspberry Pi? I have hosted emulators using the server... and I want the instruction for the compile instructions. And can you give me instructions on how to run the web server in /var/www and then run the PCjs webserver?

Disk images are pulled from internet when running locally

The "Running locally" guide mentions that when doing so local disk images are used, but I don't see it to be the case:

From what I managed to understand, the following code is responsible for this:

Unfortunately, the actual web page uses its "compiled" version, where this check is thrown away which forces it not to even consider trying fetching the disk locally:

Now, looking at https://github.com/jeffpar/pcjs/tree/master/machines/pcx86/releases, it seems there are many different versions of that pcx86.js file and it seems different images use different versions and some of them even reference "uncompiled" versions of it. How does it happen?

How do I fix this?

Ultimately, I want my custom diskette image loaded. I added it to /configs/pcx86/diskettes.json and I see it appear in the drop down box, but when I actually try to load it, the request is sent to diskettes.pcjs.org where it obviously does not exist.

The internet

How to connect to the internet and install web browsers in Windows 95?

Can't mount external CD-ROM

When using the pcjs machine at https://www.pcjs.org/machines/pcx86/ibm/5170/vga/cdrom/?debugger=true I can't load an external ISO, the error being "FDC: Unrecognized disk format (24338432 bytes)".

It seems the code behind the "mount" button always assumes that the file should be mounted on the floppy drive?

Looks like all the emulators are operating below their set maximum speed.

Not sure when this started. Just trying the Windows 95 RTM virtual machine and I have noticed that it's operating at a snails pace. Started the debugger and the emulated clock speed is way below the 16MHz setting and the clock speed can't be changed.

Screen shot:

Slow on Microsoft Edge too, but not as slow as is within Firefox.

I shall continue testing. My machine is essentially gaming laptop and with the emulator running and everything else, about 30% CPU usage.

ERROR `/api/v1/dump' not found.

Running pcjs locally.

When trying to load a ROM then backend reports
ERROR `/api/v1/dump' not found.

The debugger reports:
ROMx86: Unable to load system ROM (error 404: http://localhost:4000/api/v1/dump?file=/machines/pcx86/ibm/5160/rom/fdc/floppy_bios.bin&format=bytes&decimal=true)
(I created the fdc/floppy_bios.bin file)

I got the impression conversion to json was automatic but seeing this, it looks like that feature is broken.

Can Windows 95 be connected to the Internet?

I am aware of the perils of connecting an unpatched Windows installation to the Internet - but I thought it might be fun to try out old versions of Internet Explorer.

Is that possible - or just a very silly idea?

Thanks for the brilliant website.

IBM PC AT Diagnostics 2.07(Adv)

I am using 86Box and I tried to boot from this disk, and it asked me if a ran this program after the battery has been connected, I typed N and few seconds later it displayed "System Board Error". What should I do? Could you please help me?

MINIX 1.1 for PC ATs boots but fails to load the "Root" diskette

There is a similar problem with MINIX 1.1 for PCs and PC XTs using the 360K diskette images, but let's start by debugging the PC AT version here. The test machine has 640K of RAM, which is more than the 512K stated minimum.

hosting sever without going to the main page.

I was wondering if it is possible to host this server without connecting to the main blog page to retrieve disks? I have been able to compile everything fine, but I am running a offline intranet page which does not connect to the internet. I can host the machines fine and manually upload disks into them but it is a bit clunky. PS love this webpage!
