@theory_retro @Genesis8bit It works just fine :)

Today is the final collapse of the Arecibo Observatory. In 2020, it lost its iconic 305-meter dish. Now, all the remaining instruments and computers will be closing down. Only a few people would be left there to transition to an educational center in the following months. 😕

@theory_retro @DX_Deksor Actually, ZuluSCSI does not use ArdSCSino's SCSI code at all. Instead, it uses SCSI2SD V6's SCSI command handling code as a library, as does BlueSCSI V2 firmware, which is a fork of ZuluSCSI's firmware.

@ronscompvids @sophaskins This is a factually inaccurate statement. BlueSCSI V2 performance is equivalent to ZuluSCSIs RP2040 perf, because we actually wrote the PIO acceleration code that's used in BlueSCSI V2, which is a fork of the ZuluSCSI firmware. But don't let those pesky facts get in the way!

[ZuluSCSI @zuluscsi]

@sophaskins While it's a nice idea, it's effectively impossible to do in practice, because the way each platform implements SCSI acceleration is tightly coupled to the underlying hardware it was designed for. On the case of the ZuluSCSI RP2040, we're having heavy use of it's PIO hardware.

BTW, out of curiosity, I now tweaked the Blizzard's settings via UnitControl, and repeated the tests in 10MB/sec sync mode. The values change but the pattern remains - the SCSI2SD v6 is still ahead of the ZuluSCSI RP2040. But not by much.

[Károly Balogh - @[email protected] @chainq]

Bought a ZuluSCSI RP2040 a while ago, finally found some time to play with it and benchmark it against the SCSI2SD v6 on my A2000/Blizzard 2060. Further details in the thread. 🧵 #amiga

Migrating my A3000 HDD from SCSI2SD to ZuluSCSI seems to be a breeze /w Initiator Mode #Amiga

@DextersTechLab We're actively working on higher-performance options, and in fact, if you have a ZuluSCSI RP2040, the latest firmware release, 1.2.0, significantly improves write speeds, firmware-level optimization. Write speeds are now up to ~3.9 MB/sec, for ZuluSCSI RP2040

[Kyle Feller @fakekylefeller]

@zuluscsi Thank you! 🙏 this was indeed my issue, thank you for making such a great product!

[ZuluSCSI @zuluscsi]

@fakekylefeller Your SD card _must_ have a DOS/MBR-style partition map. If you maybe formatted an SD card with GPT as the partition type, that would certainly explain it.

[ZuluSCSI @zuluscsi]

@DextersTechLab Let us know how it goes!

[ZuluSCSI @zuluscsi]

@parneetsingh @BlueScsi We haven't seen any e-mails where either Stabuli or JC5 has been mentioned, in the context of ZuluSCSI, but we're confident ZuluSCSI will work fine with the Staubli JC5.

@kurist2010 Which hardware version of ZuluSCSI are you using? V1.1?

@G2Genesis @systems_glitch We've reached out with answers to your questions. We have a ZuluSCSI distributor in the UK. See https://t.co/lmnyF44cby for a list of resellers.

[ZuluSCSI @zuluscsi]

@GarthBeagle The release of ZuluSCSI firmware version 1.0.6, which fixes this issue, can be downloaded from https://t.co/dPm1Zsld96

[ZuluSCSI @zuluscsi]

@GarthBeagle We believe this 10MB/sec synchronous SCSI bug is now fully resolved as of ZuluSCSI firmware version 1.0.6-rc2. @GarthBeagle has already confirmed in the GitHub issue that was opened for this issue. The 1.0.6-rc2 release candidate can be downloaded from https://t.co/iAtxaf16fR
