PDP-8/E Simulator 2.5.1

[Bernhard Baehr]

Hi all, there is a small optimization update available for the Macintosh PDP-8/E Simulator:

- The Memory Content and the VC8-E plug-ins now use CALayer based updates, significantly reducing the CPU load of the simulator.
- The RK05 drives are now able to mount SIMH DECpack images (with each 12-bit word stored in two bytes) directly; the images no longer need to be converted with the s2p and p2s tools.
- The Music Player plug-in no longer causes occasional skips of the music and avoids a deadlock in the AVAudioEngine when the simulator plays music while running at full speed.
- The OS/8 System Disk now contains the Popcorn piece arranged by Kyle Owen (RKB0:POPCRN.MU), see https://www.youtube.com/watch?v=6HI5EU_f6RI (Kyle, thanks again for this great fun).
- The indicator panel and drive select lights of the TC08 are now more consistent when restarting, resetting or clearing the simulator or the PDP-8/E or when the user manually changes Status Register A.
- Additionaly other minor bug fixes and adjustments esp. for macOS 13 “Ventura”.

As always, you can download the new version from https://www.bernhard-baehr.de/pdp8e/pdp8e.html.

Thanks Bernhard,
Seems to be more than just a small optimization update. Looks to me like it also includes a second ASR-33 TTY: as well as PC08 PTR:/PTP:

I've been running this update for a couple of weeks and I've been happy with it.
