For anyone that needs true native serial & parallel ports, a Dell Latitude E series laptop (or Precision 7xx0) with docking station is an easily-available option.

The last machines with dock port have 6th gen Core CPUs (Latitude E5x70), or 7th gen for Precision 7x20.

The "FD32" 32MB capability was only implemented on the last drives which could also use 240MB disks.

Maybe the earlier 120MB drive hardware could have been physically capable of it but the drive firmware did not support it.

In fairness BECO inception date was 3 Aug 2021, so under 5 years.

Also, Ghidra's decompiler works with many CPU architectures whereas IDA only supports a few.

If you want to know the details of how it works, see US patent 4851826: https://patents.google.com/patent/US4851826A/en

BBoAH has a pic of an actual A2024: https://bigbookofamigahardware.com/bboah/product.aspx?id=863

There was also a separate video card containing the framebuffer hardware, that could be connected to a "normal" high-res mono monitor: http://amiga.resource.cx/exp/moniterm

That would be the A2024 which is emulated by WinUAE. It did not flicker or have long persistence phosphor. What it did have was frame buffer RAM on-board. The video signal output by the Amiga determined which 1/4 or 1/6 of the screen was refreshed. The driver code had a feature where the pane containing the mouse pointer could be refreshed more frequently.
