I have been contemplating on pfSense hardware as there has been a large shortage on that market especially for having more than 2 ports (similar to for instance Mikrotik PoE router unavailability).
If by now I have not found any, I might want to revisit [Wayback/Archive] Gowin R86S mini PC offers 2.5GbE and 10GbE networking for $310 and up – CNX Software has 3 RJ45 ports and 2 SFP+ cages.
They found it via this 4 page review:

[Wayback/Archive] GS305E | Easy Smart Managed Essentials Switch | NETGEAR Support which can do many-to-one port mirroring.
This is a newer and cheaper hardware revision than the:
- GS105Ev2 (which is managed and can do port-mirroring, and is confusingly sold as GS105E-200) which in Germany already is end-of-life
- GS105Ev1 (which is unmanaged and cannot do port-mirroring and is confusingly sold as GS105E-100) which is end-of-life but still sold
Via [Wayback/Archive] Everyone Should Have One of These – EASY Packet Capture! – YouTube who explains very well why you need a switch that can do port-mirroring, then recommends the GS105E but forgets to mention:
- there are different revisions of the GS105E with the above drawbacks
- there is GS305E

Often after having taught a topic for decades, somebody rephrases it in a beautiful concise way:
[Wayback Comment Only What the Code Cannot Say | by Kevlin Henney | Medium
Kevlin has the same two quotes I have included teaching software quality for a long time:
A comment is of zero (or negative) value if it is wrong.
Instead of writing apologies and apologia, follow Kernighan and Plauger’s advice from the 1970s:
Don’t comment bad code — rewrite it.

I missed this back then, so here is a reminder: [Wayback/Archive] Toru Iwatani shows his original drafts for Pac-Man : gaming
Of course these had a big red stamp on them marking them classified. The detailed game experience and sprite transformations in just a few pages really shows how great Toru Iwatani was.

I’m vintage, so I have some old machinery but also want to be able to run old software on newer hardware.
TL;DR: Since Apple Silicon (which is based on ARM) uses Intel Emulation for regular Mac binary programs, VMware Fusion# on Mac M* series cannot run Intel based operating systems, after some research there basically were these options:
- use VMware Fusion and run inside a Windows on ARM VM by using
- a dos emulator like DOSBox or DOSBox-X, since modern 64-bit Windows lacks the NTVDM:
Since virtual 8086 mode is not available on non-x86-based processors (more specifically, MIPS, DEC Alpha, and PowerPC) NTVDM is instead implemented as a full emulator in these versions of NT, using code licensed from Insignia’s SoftPC. Up to Windows NT 3.51, only 80286 emulation is available. With Windows NT 4.0, 486 emulation was added.
NTVDM is not included with 64-bit versions of Windows or ARM32 based versions such as Windows RT or Windows 10 IoT Core. The last version of Windows to include the component is Windows 10, as Windows 11 dropped support for 32-bit processors.
- an NTVDM replacement like NTVDMx64 or winevdm (sometimes calles otvdm)
- use a specific emulator like DOSBox-X directly on MacOS
- use a more generic emulator like QEMU based UTM
I have a VMware background on bare metal, Windows and MacOS, so I prefer it over Parallels
