New S-132 firmware release (1.8.0) available on GitHub

[dmcnaugh]

S-132 firmware V1.8.0 - May 2026

This is a MINOR release that

• adds SDH-100 host support with a host-aware System Menu including Memory Map and Boot Log views
• adds Save Cfg / Restore Cfg for the complete S-132 configuration in NVRAM (Initial Device, D+7AIO, Dazzler, VIO)
• adds an alternate ORANGE palette to the Dazzler (DZLR:), cycled with PgUp and persisted in NVRAM, alongside a brighter primary-colour palette
• adds hardware flow control to LPT: pass-through on the D+7AIO so the host pauses while the parallel-port printer is busy
• shows >-prefixed remote disk images in the Library (LIB:) listing
• routes keyboard input from the Dazzler screen to the most recently active TTY: or VIO:
• adds Ctrl-Alt-Space as an alternate SETUP chord for USB keyboards without SYSRQ / PrtScr
• smooths System-Menu list rendering under arrow-key navigation
• updates the on-board UHC (USB host controller) firmware with USB hub support

See the release notes for more details.

This is very exciting for me. I love the addition of the save restore config so that it can start up in a particular mode!

Also the usb update is epic as I have been wanting to use a 2 or 4 button keyboard module to be able to switch between modes without having to have a full keyboard plugged in, but these all seem to have usb hubs built into them so they didn't work before.

I have successfully updated the S-132, but I'm not sure how to proceed with the UHC update. I haven't been able to find any instructions on how to update that specifically for the S-132. The vt-132 ones say to short out some pins that are under the pcb board, but I'm not quite sure how to do that with the s-132 since it has to be installed to function, so those pads are not accessible.

There's a link mentioned in the UHC Firmware Upgrade screen, but it seems to be invalid.
