Hardware / Re: Modern Motherboards - Whats working
« on: May 25, 2024, 09:19:18 pm »

I documented some reported working mainboards on the OS2World wiki, right here:

But I don't think they have PS2 ports anymore.


PS/2 ports are on most modern systems dead as doornail. Maybe industrial mainboards (that are sometimes pretty expensive), still tend to have PS/2 ports.
The more modern systems the 8042 PS/2 controller is also going away from the mainboards.


Most motherboards on the market have at the least 1 PS/2 connector that is usable as either KB or mouse, a few specialist gaming boards skip them altogether but that is not the norm at all yet. If one is all that is needed you can choose from a number of AM5 or 12/13th Intel based boards.

"Business boards", i.e. LTS boards designed for long term support contracts frequently have both KB/Mouse connectors but feature slightly older chipsets as in the case of Intel in particular, the "business" chipsets are frequently not shipped in volume until long after the "performance" ones, even if they are announced at the same time. I am running this with a Ryzen 5500:

Not the newest board but, received an updated version late last year when I bought it and with Ryzen 3 support that is not really an issue speed wise, and the PCI slot comes in handy. ASUS still has at the least one PS/2 connector on most of their boards, but on AMD670 and Intel 760/90 gaming boards only some of the PRIME boards have them.

The LTS type boards are not always available to the public since they are intended for the OEM market, but large OEM makers such as Pegatron (DELL, HP, Acer etc) et al have them in their lineup, sold under a variety of names. The Asus is sold to end users however:

ASROCK has at the least 1 PS/2 connector on all intel boards bar a few intel 790 boards, it is missing from a number of AMD 6xx series boards but LTS boards such the AM5 actually have 2.

MSI has a few as well: This one is similar to the Asus minus the  PCI socket:
Most other MSI board have a single PS/2 connector

Most Gigabyte boards have at the least 1 connector, their LTS boards have two like this:

Biostar has 1 connector on everything except Intel 7xx gaming boards, the consumer 7xx boards have 1 however
Their AMD LTS boards have 2 PS/2 connectors but the Intel ones only one for some reason

Applications / Re: WordPro issues

Hello all,

Somehow, WordPro started having some issues, without my touching any setting nor doing any update:
- When creating a blank file, it complains that it cannot open the default.mwp (that, I checked, is in its folder, and I copied one from another installation, to no avail)
- The icons at the top have all disappeared.Ctrl+q (or the equivalent menu) does not change anything, that menu never gets selected.

Any idea how to fix that?

There was an issue with an SS dll file that would get corrupted for some reason, I just cannot for the life of me remember what the dll was, but if you have another install, you could do a file comparison.

I believe Hyperthreading is an Intel only feature - meaning it only appears on Intel CPUs.  If I understand it correctly Hyperthreading was/is a technology by Intel to provide some of the benefit of multiple cores without actually having all of the hardware of the multiple cores.

It is not an Intel only feature, it appeared originally on minicomputers specialised in database jobs and on some workstation/server chips, a number of the later SPARC chips have hyperthreading. The original idea is literally to speed up database jobs by having a parallel hardware threads packing inherently inefficient relational database code into something more efficiently executed on a normal CPU core, this gave you a 7 to 20% speedups in specialised tasks for for a 3% to 8% increase in transistor count. Intel originally introduced Hyperthreading on Xeons as an answer to Sun SPARC's with hyperthreading close to 20 years ago.

Even though current versions of HT are a bit more generic than the original designs they still have the same flaw, the code is packed out of order, and there is a slight unpredictable (fuzzy) delay in reordering it, not an issue in most cases, but for hard real time work such as some drivers and audio applications that get their timing reference from the soundcard rather than the CPU, this leads to hiccups. As an example on Windows, most professional audio programs that require a single timing reference (not all do) simply turn off HT via ACPI while they are running, turning it back on again when they exit.

SPARC server chips were not doing any hard real time work so this was never really an issue with them, however it became an issue as soon as Xeons came out since they were being used for real time audio and video work. I still turn HT off on my Intel machines regardless of OS due to past experiences with driver and app issues, and even on Windows I have never really found an application that takes advantage of HT to such a degree to make me consider turning it on again, but your milage may vary.

Hi Richard

An alternative to c and rexx is pascal - very similar to c.

WDSibyl is a fairly good RAD system, similar to Delphi, and may be of interest

That website has some issues, you can try the archive instead at

Vispro/Rexx is now free but not open source, you can download it here:

Ar you sure the sectors containing the library file are good?

Try downloading and see if you get the same error.

I can't get Arca Mapper Network Connections to function. After many tries using 3 machines I was unable to det the Network Browser to work I've tried using different settings for Protocol in SMB config and got nowhere.. Don't know what else to try. Anybody got any  luck with this new setup for Samba --- Thanks for any ideas.

Do not know if it is the same issue, but some 5.1 users are reporting that Arcamapper does not install correctly, a reinstall has helped for some.

Sorry I wrote that text about 12 years ago when I still worked at Mensys. It was intended to READ if you want to use MORE then 5 license you need to buy a commercial license.
It NEVER intended to imply you can use eCS personal license in upto 5 devices at the same time. Thats a violation of the OS/2 EULA.

I know, I was not wondering about the license useage, but about the number 3 vs 5

Off Topic discussions / Re: John Poole Software Operating System/5?
« on: September 01, 2023, 03:16:05 pm »
I came across this video and website showing called OS/5 by John Poole Software. I thought it was interesting.
One can still download it?
Here is the information on it from the video on YouTube
OS/5 is a Shareware PC operating system based on a Microsoft programming language that itself was rarely used. Intended to be an inexpensive, lightweight alternative to Windows, OS/2, and other graphical user interfaces, OS/5's Desktop runs in text mode while retaining many GUI features. Created by John Poole and released in 1996, two versions of it are known to exist, and would have been lost entirely if I had not saved them over 25 years ago, because they have not been archived anywhere online and trying to search for OS/5 or its author will turn up nothing except this video.

Download OS/5 version 1.0:
Download OS/5 version 1.1:
Ignore any security warnings; I run the site and it does not store any personal data. Feel free to archive these files elsewhere.

It is a simple DOS shell that was written in Visual basic for DOS (V1 presumably, I think 2 and up were Win only), it is very rudimentary even for a Shareware DOS shell.

In the eCS license text an error slipped that I had written. It was intended to read you are only allowed to use more then 3 personal licenses of eCS.

This can also be read that eCS can be installed on 3 systems (personal version). But this is NOT correct.

Did you mean 5?

"eComStation 2.1 versions:
eComStation 2.1 is released in two flavours:

The Home & Student version can be used by any private or small office user. As a private or small office user, it is allowed to have up to 5 licenses installed for production usage. This version includes 6 months of Software Subscription Services.

If more than 5 licenses are needed, it is required to purchase the Business Edition. The Business Edition includes 12 months of Software Subscription Services. Volume discounts are available for the Business Edition."

I got some ISOs to try. Win98se does not load at all. Tries to boot from CD and then VBox aborts loading. Going to try another ISO.

As an alternative, if you cannot get VBox functioning, VirtualPC for OS/2 runs all older Microsoft OS's and SVista runs most of them.

Hello. So, officially we are looking for the VABasic 1.5 patch for OS/2 that used to be publicly available on the IBM support Site.
If someone has the filename, dead link, or (more important) the file, please let me know.
There was a large 1.2 patch for both OS/2 and Windows before 1.5, even that would be better than nothing as it solved a lot of issues.

Hi Martin,

as far as I know, there were only full versions of VABasic.
No, IBM issued patches for VA Basic, for some reason it was only available from the website and not from any of their FTP sites and I lost my copies of the patches in a Partition Magic related incident in 2000, by that time IBM had taken down the website.

Panorama nor Snap will not work on either the Nvidia MX400 or an S3 Trio I have and the only way I could see anything was to setup as SVGA
SNAP should work on those two cards, but as an alternative both of these cards have a discrete native OS/2 drivers, in the case of the S3 Trio, both classic and GRADD versions.

ArcaOS does not support 6x86 chips like the K6 BTW, some of the Arca supplied code is compiled for 686 using GCC and may not work on your setup. eCS is a much better bet.
