The new ZuluSCSI RP2040 & ZuluSCSI Compact Homebrew

E411 - In this episode I review and test the new ZuluSCSI RP2040 & ZuluSCSI Compact Homebrew from Rabbit Hole Computing. ZuluSCSI RP2040 has more features and is twice as fast as my original ZuluSCSI V1.1 on my Amiga 4000/060 . I test the full size and the new Homebrew kit assembly.

Just found this video of yours. Have to prepare my Zuluscsi v1.1 for my A4000, so I believe this will be my definitive source of informations.

[@GhettofingerGaming]

These make the A590 sing.....your videos always take my wallet down the rabbit hole.

[@James_T_Quirk]

I really liked how Chris ripped into that Soldering, Nice to see him keen & doing some work for himself, instead of A4000 rescued from a Mars Probe that burnt up on re-entry ..

[@GadgetUK164]

They are great!!! Looking forward to tinkering with the one I have here!

[@DikkeBetha]

Couple of benchmarks (all my Amiga's run ROM/OS 3.1.4) My A4000T with BFG9060 @ 100MHz and the onboard SCSI-controller: 8.45 MB/s read and 6.21 MB/s write. My A3000D with WarpEngine 3040 @ 40MHz and the WarpDrive SCSI-controller: 9.38 MB/s read and 6.52 MB/s write. (this cleary shows how good the architecture of the WarpEngine and it's SCSI implementation is).

And another great informative video! One of my Scsi HDs died a couple of days ago! I am using my azulscsi but is slow, 1.6Mb max, seems this new versions of the zulu are a lot better! Thanks for sharing

[@stefanjohansson3578]

Yeah I got one RP2040 in my Akai MPC3000, works great!

[@TheNovum]

i allways think about you first video when i use my Zuluscsi, Works fantastic, But the thing whould be for me atleast scsi to sata, so you get some noises too 😆

[@boodeini191]

Just got mines working in my akai mpc 2000xl 💪🏾💪🏾💪🏾gonna try and see if I can also use the cd rom on the mpc via the Zulu mini 🤞🏾

[@cullmaster7361]

Darn it Chris! I’m going to have to sell a Kidney with all these reviews! 😂 A lot cheaper when I bought some Scsi2SD V6’s a few years back too! 👍🏻 Just to point out. The speed can also be dependent on SCSI controller and Filesystem being used on the Amiga 😉 For example I’m running SCSI2SD V6’s with PFs3 V 19.2 Filesystem with Myunitcontrol in Startup-Sequence pushing a Phase 5 Blizzard 060/PPC 603e+ card to try for 10Mbits at synchronous speeds. I do manage over 8Mbits on read and write speeds. Might be worth a look. 🍻

[@a4000t]

Hopefully u are seeing 8megabytes speed because 8megabits would be less than 1MB/second lol. Good speed you see.

[@memadmax69]

That Zulu movie... ZuuuuuuuuLuuuuuuu. Anyways, very nice cards.

[@stephenbruce8320]

Get your Credit Card Out. LMFAO. Hey I bought the first one and its still sitting in the Pile of things to install. Yea I have an issue with buying ton's of things that seem to wait for me to get motivated to open up an Amiga and lately I have been printing a ton of things for my Amiga's so yea I will be opening them up here and there and my A2k and A3K are on my list of Amiga's to open up so I will order a couple boards but not until they repave my area so maybe in Aug that way there will be no issues with delivery. Your friend who printed a full length A1K back panel, is he selling them? I had to print 3 panels which is fine but I would rather have one full length panel.

[@DAVIDGREGORYKERR]

Has anyone tried a SCSILVD to SATA adapter and you can have a CORSAIR 256GB SSD installed.

[@sumselbrumsel]

Hi Chris, thank you for your always helpful and informative videos. I've been using the ZuluSCSI RP20240 in my Amiga 3000D on the original controller for about 2 months. Unfortunately I can't get over 2200MBytes/s. What can I do? As CPU I used a 68060 50MHz.

[@ChrisEdwardsRestoration]

Update your scsi.device driver. and i have a updated AMD scsi chip vs the western digital proto factory one. fixed some issues and was like only 16 usd on ebay

[@sumselbrumsel]

@@ChrisEdwardsRestoration Okay, I already have the AMD SCSI chip in the drawer. I'll install it then. Hope the chip works. The first one from China didn't work. Where can I get a newer SCSI.device driver version than the one included in Kickstart 3.2.2?

[@keith1200RetroComputers]

Kinda good price for the kit. Have you tried with the A2000/A3000?

[@ChrisEdwardsRestoration]

3000T and 4000T so far. working great!

[@finite934]

can you weigh in on Bluescsi vs Zuluscsi? Is the fact that you're presenting Zulu an endorsement on your part? What are the benefits of Zulu and is it more stable or same-same? are the pros/cons to SD over CF card?

[@ChrisEdwardsRestoration]

thats just what i bought, Blue is mainly for macs and made for them, while its fine, the features of Zulu are imho better, as it runs from hard disk files not like the old blue or scsi2sd. where you are stuck w that card, i can have multiple images on one sd for many different computers. or os versions for the same computer. in my case Amiga os versions

[@pauloespadinha2754]

Hi, Tanks for your video. Question does the zuluscsi rp2040 can replace and scsci interface as an syqyest or cd-rom by remove it from the original housing and put the zulu pcb ? Does the zulu pcb needs to be power supply ? Also have you test if it is possible to have the zuluscsi rp2040 working with both db25 and 50 pins connected ? Thanks, Paulo

[@ChrisEdwardsRestoration]

the zulu uses hard disk files to emulate hard drives as a scsi id on its SD card. it can be run via db25 or 50 pin ribbon (sold both ways or with both or as a kit) certain models like the 4000/4000T have scsi term power and it does not require a berg, others do. it depends on the Amiga or scsi card powering it. you an have other devices on the scsi bus like our syquest, as long as the id is not used with a file in the zulu. hope that helps.

[@pauloespadinha2754]

Thank you for your support.. It's for using with akai samplers one side with one end with an s1000 and the orhzr end an s950 in daisy chain in the middle the zuluscsi inside a syquest, cd-rom, or hard drive housing or using both connectors on the pcb You think it will work ? I got also an amiga 500+..but it not for using with it ..😊😋

[@ChrisEdwardsRestoration]

i have used it as a external db25 and internal 50pin scsi cable and it works fine. it just emulates a device. its device id is 7 so make sure your other controllers are not using its scsi id , and any internal hard disk file as i showed named hd0.hda would be id0 hd1.hda would be hard drive id 1 etc... normal scsi termination rules apply .

[@pauloespadinha2754]

Thanks a lot ..merci beaucoup !

[@ikestoddard2458]

Hi, Chris! To pull data off Ami SCSI hard drives, either onto microSD or via USB to Linux, which solution would you choose? I have a RaspPi Pico W to cannibalise if needed. Cheers!

[@ChrisEdwardsRestoration]

you can use the Zulu to image old scsi drives. you dont even need a computer to do it, just power the zulu with a jumper flipped and it will block level image the drive to a zulu file on the sd card!. maybe i should do a video on this...

[@ikestoddard2458]

@@ChrisEdwardsRestorationexactly as needed! Which Zulu card has the jumper? And what is your discount code?

[@ChrisEdwardsRestoration]

i have discount codes on retrorewind.ca code NOCODE, but nothing on the zuluscsi website. they are cheap enough. all of them have the jumper@@ikestoddard2458

[@janwiersma1449]

I wonder if this zulu board would work in my Casablanca from MacroSystems.

[@ChrisEdwardsRestoration]

Anything with a Scsi bus that takes 50 pin ribbon or db25

[@ZuluSCSI]

It should be fast enough to, yes.

[@jjdigitalvideosolutionsllc5343]

Does it work with Toaster Flyer?

[@ChrisEdwardsRestoration]

Any scsi device

[@noggin73]

Nice. BlueSCSI V2 is another option. Works fine with many Amigas.

[@ChrisEdwardsRestoration]

no way, zulu is superior to old blue

[@NdxtremePro]

So, is the MicroSD card faster with an SD adapter in the 2040?

[@ChrisEdwardsRestoration]

you would think, but adapts to a standard SD and its functions

[@NdxtremePro]

@@ChrisEdwardsRestoration No free lunches anywhere, huh.

[@Snowcrash777]

I just installed a Zulu RP2040 on a PPS Zeuz 040/33MHz and I'm around 8MBs average and 10MBs peak after some tinkering. The one thing that is not covered by the instructions or most of the KZbin videos on the Zulu is the fact that it doesn't like to play well with accelerators that are the SCSI host. "Q" of Hold and Modify actual ran into this issue in his video on the Zulu. I even contacted support at Rabbit Hole and the owner did not think to mention this either. Until you run the accelerator's HDtools or change the scsi.device to the SCSI controller's naming convention the drives will not show up.

[@ericjohnson6105]

Does a mechanical HDD (or CDROM) get any transfer rates benefit from this new device?

[@ChrisEdwardsRestoration]

that would be directly on your scsi controllers speed. this device uses hard disk files to emulate actual hard disks and scsi devices within itself, you can mount .iso files for a fake cdrom by using cd2.iso and cd3.iso for id's 2 and 3 type of thing,

[@Krslaurent]

que pensez vous de bluescsi v2?

[@ChrisEdwardsRestoration]

This is WAY better

[@wowtechniplex]

Have you tried BlueSCSI v2? I built a few of them and have one I can send for you to review. My tests show that it not a bad option for my Amigas (A3000T, A2000, A4000 w/ FastLane). Uses the same RP2040 processor. Just PM me.

[@wowtechniplex]

@ChrisEdwardsRestoration As an experiment, I just put the ZuluSCSI RP2040 code on a BlueSCSIv2 and it works and reports as ZuluSCSI. Do you have a BlueSCSI v2 and have you seen performance differences between the 2 code bases which are very similar apparently?

[@nielshkristensen1815]

i don't know why but if i have to buy one her in EU then i have to pay the double of is normal price that weary sad to see 😞 total insane

[@ChrisEdwardsRestoration]

but it in usa for a lesser price, but our shipping sucks buttfarts outside of the country right now
