Virtualization / Re: What Needs to be done for ...

Last post by andreas_g - Mar 06, 2026, 06:52 AM

Great! I'll update the code in the repository later today.

Short explanation: I was a bit too optimistic when adding support for the system timer downcounter. As it turned out, tiny inaccuracies could cause the counter to underflow (wrap to maximum value). The patch protects it against underflow.

It looks very much like an underflow. Can you try if the appended patch fixes it?

systemtimer.diff

It's perfect now! Thank you!

Marketplace / Selling off my NeXT Collection

Last post by wmlive - Mar 05, 2026, 10:48 PM

No, not me, but someone else (i never had nor would ever want to have any space consuming NeXT hardware):

Code Select Expand

I'm selling my entire NeXT collection piece by piece - cubes, slabs, displays, printers, keyboards, mice, peripherals, boards, cables, etc.
See tinkerdifferent.com/threads/selling-off-my-next-collection.5123/ for more details.

The new timing system is giving me weird results in linux using ping, although it may be entirely my fault.
ping works fine on real hardware. Just wanted to let you know:

Thank you for the report! How did this look like in Previous v4.0?

With less precision, but no weird times:

VMS! Man, I remember not being fond of being forced to use it back in my school days!

Off Topic / OpenVMS for Linux Users

Last post by Rhetorica - Mar 05, 2026, 03:49 PM

For some reason I don't really recall, I'm subscribed to the VSI channel on YouTube, and they put out this video this morning:

Of course it's aimed at helping their current customers get up to speed on how to pump big iron on legacy systems, but one can readily imagine that most of the fundamentals transfer to the 1980s context just as well, with the VMS–BSD contrast being a familiar experience to anyone near a university or big company. Very important background info when thinking about how BSD-derived systems like NeXT were perceived and experienced when they were new.

Hello all,

I am happy to announce the release of Previous v4.1! I have updated the timing system. It should be a bit more efficient and much more accurate in variable speed mode.

It also includes some minor stability improvements and bug fixes.

As usual I have compiled a binary for macOS v10.13 and later (Intel and Apple Silicon). You can load the binary here.

Have fun and feel free to report any issues.

The Previous packages at wmlive.rumbero.org/repo/pool/main/p/previous/ have been updated to version 4.1-r1777.
The binary packages were built for target release Debian/Trixie and CPU architectures i386, amd64, and arm64.

Great! I've mirrored them as usual.
