ZuluSCSI

@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.

Here's a recent Macintosh Quadra 800 restoration project that I've completed... writtenoutput.blogspot.com/2023/07/macint… @RDKLInc @zuluscsi

@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!

@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.

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

@zuluscsi I will! There is concern over the write speed but until i start testing we just don't know. I think for the most part these type of converters work well but i do think it's time for a SCSI / SD product to use another approach to achieve maximum performance, both read and write!

#Quantel HAL / Dylan Update:🧵 The Dylan disk array work is progressing, the PSU exploded so that is out being repaired, it's had a good general clean up too so it's not quite so dirty!

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

@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 Trying to get my NeXTStation working with a ZuluSCSI 1.1 but keep getting the 3 light blinks even though I have a properly named ISO file on my correctly formatted SD Card... Help! Thank you!

@DextersTechLab Let us know how it goes!

Now on a more serious matter, you may remember i sent a plea out to anyone who might have a specific drive i was looking for to replace 4 dead disks. Well i found 2 working drives in the USA and for the other two drives i am going to try the ZuluSCSI RP2040!

@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.

@BlueScsi Please advise on working of bluescsi on staubli Jc5 Machines. I sent a mail to @zuluscsi but no one responds. Thanks

@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 zuluscsi.com/wheretobuy for a list of resellers.

@systems_glitch Thanks. Will do!

@GarthBeagle The release of ZuluSCSI firmware version 1.0.6, which fixes this issue, can be downloaded from github.com/ZuluSCSI/ZuluS…

Confirmed! ZuluSCSI does NOT like the internal SCSI bus (Apple MESH) on Power Macintosh 7300 and 9600 It will work ok off the internal/external SCSI bus (Apple NCR) or a single SCSI bus on older Macs (eg: LC475) I thought I got working once, though this is the recreation 🤷‍♂️

SCSI! 😩

@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 github.com/ZuluSCSI/ZuluS…
