New #BlueSCSI release github.com/BlueSCSI/BlueSCSI-v

Highlights:
* USB<>SCSI Bridge
* USB Thumb Drive Mode
* SD Bootloader
* 200MHz default
* Auto Buttons on all HW
* FAST20 speed
* Interactive console

I'll highlight a few of them in this post:

USB<>SCSI Bridge

If you were holding on to those rare and expensive USB<>SCSI bridges for your retirement fund, sorry! Now your BlueSCSI can do it with a one line config.

First person to boot Windows off a Quantum Fireball SCSI drive over this gets a prize!

USB Thumb Drive Mode

It's sometimes annoying to pull out the SD card when you want to edit a config file or copy a small file over - now BlueSCSI acts like a USB thumb drive when connected to a computer and will present the SD card or even the Images to the modern PC.

SD card bootloader

Ya, we let this one go too long, had a bug and wanted to re-do the entire thing but we ended up just adding it back. Update by placing a bin on the sd card.

200MHz default

The Pi Foundation said 200MHz is good and so many project already OverClock way beyond that, we thought we'd catch up now too. Can clock up to 250MHz now too for FAST20 support - up to 18MB/Sec

Auto Buttons on all HW

Ever wanted a button to eject your CD or removable media? Well now you can add it to every hardware rev and no configuration is required!

Lastly this one is mostly for developers (for now) but an interactive console - just type 'h' when connected via a USB Serial program

There's lots more - checkout the release notes! /🧵

User came on Discord today complaining how hard it was to configure RAW mode on BlueSCSI - they were right! So I automated it all.

Seems samplers users like the RAW partitioned SD workflow instead of images.

This also allows you to pop in a SCSI2SD card into your BlueSCSI for a easy upgrade.

@wyatt Also glancing from the #PC98 architecture and specific quirks that #Linux accounts for in menuconfig it's most likely not gonna be enough to "just boot the #i486 version of @OS1337"...

  • Tho given the fact this is just a #toybox + #musl / Linux Distro that is barely booting using #syslinux and able to spit out a 80x25 MDA console, it is in an early infancy.

As for the specifics of the #PC9821+ and their detailed hardware I'm clueless beyond the Wikipedia Article and can only Assume anything before a (RAM-upgraded) #9821Ap & #9801BA is off the table and a #9821Af or better is desireable as the 14,6MB RAM limit will really become a problem quickly, as I'm pretty shure it's impossible to get linux-6.6.6 run on anything below 8MB at all and most recommendations hint that 16MB is more often than not a practical limit (tho that may be becaise 10/12/14 and other "asymetric" configurations were already avoided back then)...

  • The #9821Ce should be workable in theory tho again that's just me reading a specsheet.

On the flipside I did manage to install #WindowsXP on machines with 32MB RAM and actually get them to display a desktop (abeit with seconds per frame instead of frames per second) so this is more likely a question of chipping down things.

  • Worst-Case one could see to build a bootable CD-ROM or dd something on a #BlueSCSI or similar...

It's week end, so again on the #powerbook 170.
I removed the cmos battery to avoid future leaks, and made the trackball finally work replacing a capacitor and cleaning/re-setting all the connectors.
Now on the #bluescsi. No way to make this thing to boot from it. I tried formatting the virtual disk from the 170 instead of creating from the pc. It formats but then while copying the files I have a lot of i/o errors. It seems like it bursts for some seconds and then hangs. The OS seems waiting a bit and then showing the error, maybe after a #scsi timeout...
Not sure how to troubleshoot this. The bluescsi log in the microSD doesn't show any error...
