RASCSI the RPI scsi emulator for Amiga

E269: in this episode we review the RASCSI. a donation to me by Jonathan purchased from Amigakit and i thank you so much! What is it you ask? a SCSI device emulator that allows you to emulate anything on the scsi bus with the help of a raspberry pi zero w. a cdrom iso? no problem, how about a website downloaded and presented as a disk? no problem,. a hard drive? even a network card. yes that right. Even more better the thing has a WEB interface you can do all this on without a bunch of linux commands or crazy stuff. . SO i build it, 3d print a case for it , test it on my old Performa575 mac , when its verified working, i fire up the Amiga 3000 and give her a go. hope you enjoy.

If you're using the Raspberry Pi Imager you can hit the control shift and X keys to preconfigure your PI OS for various options including your WiFi network and your root passcode and all the other options you'd have to set with raspi-config and have it done while you download and burn.

[@xav500011]

If you are using Ultimaker Cura to slice your 3D stl model specify a 'Raft' in 'Build Plate Adhesion'. This should stop the base of a 3D print curling away from the print bed. But this also can create a new problem where the 3D print is stuck to the 'Raft'. For me this happens less since I starting using a glass print bed base.

[@ChrisEdwardsRestoration]

my discord pimiga team all chipped in and donated a Ender 2 , to me. what an awesome gift. its way more involved than my pos printer (wanho powerspec i3 mini) so im re learning 3d printing

[@ShaneBro]

When you say thanks for everyone that helps support your channel I can hear you walk in to an AA meeting and introducing yourself and saying I have a problem - that is the Amiga and 8/16 bit computers. This is my crack.

[@ChrisEdwardsRestoration]

AA "amigas anonymous"

[@mikerhodes9198]

Great video. Had a yugo dealer in my town back in the 60s. We were all curious but no one bought one.

[@HoldandModify]

I had no interest in this product because I knew I’d never understand it. Then I watched this video. Thank you Chris for making this! I’m happy with my SCSI2SD but it’s nice to know there’s options. This does a lot more too. Another chicken finger fueled accomplishment!

[@jjdigitalvideosolutionsllc5343]

Is SCSI2SD noticeably faster than using an actual SCSI drive? RASCSI seems be bit complicated to get going.

[@HoldandModify]

@@jjdigitalvideosolutionsllc5343 the SCSI2SD can do up to 10mb a/s. The RASCSi seems to be limited. At least from what videos I’ve seen thus far. However, even if slower, the RASCSI offers more features. I don’t have one, so it’s hard to give a more informed opinion.

[@ChrisEdwardsRestoration]

The speed of any device is limited to the Amiga scsi bus or the bus Speed of whatever device you are using

[@Outlaw17666]

Fantastic, with rpi we can have one million things on our loved Amiga :D

[@templar2b1ask]

Sorry at my age approaching 71 yrs I am finding it difficult to follow how you do what you do! Your skill sets are simply amazing!

[@ChrisEdwardsRestoration]

Theres always rewind!

[@cullmaster7361]

Nice vid Chris👍🏻 Have seen these RASCSI devices for sale and wondered what they were all about. So have learnt something again today 😉 I’m guessing your lack of speed on the RASCSI is that there is a setting for Asynchronous/Synchron setting somewhere? Have the same issues with Blizzard 1230 MKIV SCSI cards, if they aren’t set to Synchron via the SCSICONFIG as well as the speed in the software then you will get a slow speed 👍🏻😉 Still happy with my SCSI2SD version 6. Bought the latest board version. Sure it’s more money but less time needed to setup. Each to their own 😀

[@ChrisEdwardsRestoration]

its just a scsi device, the speed would be that of whatever controller card you use has.

[@stephenbruce8320]

I did buy one of those along with a couple Greaseweazle v4's. I have a bunch of those SCSI2SD Adaptors but I figured this might come in handy either in my A2000HD or A3000 down the road but I will play with it once it arrives and if I decide it's a good fit I might pick up another. I don't need one but I do like having options. It's amazing what you can do with the Pi's.

[@ChrisEdwardsRestoration]

You need to setup a youtube chan, I think you have more stuff than I do.

[@stephenbruce8320]

@@ChrisEdwardsRestoration I have quite a bit of stuff but I think you have me on that one. KZbin is a lot of work. I already have a job that puts a high demand on my time that when I am not working, I just like to rest and relax.

[@BerndFelsche]

Smiles all round. Thanks for the effort.

[@re8et355]

Could you make use of the Pi400 Pins to emulate midi ports in and out??? Impressive work! You turned comments off the Pimiga video anyway... kudos!

[@ChrisEdwardsRestoration]

I really dont know

[@jerrygibbons7666]

Chris, Just place my order for 1 at AMIGA-KIT! Thought it best to follow your advice to buy 1 before they are gone. And my LED "AMIGA" display arrived yesterday!!!

[@pkf4124]

Well I may just get one of these for S’s & G’s I mean its not like I need one to make a big scssi drive I have several multi GB ones, with more than enough space to put all my Amiga stuff on a few times over. I think I just need one.

[@router5840]

With all this learning I think I need a memory upgrade :)

[@MrAlan1828]

I would love to make this for my Amiga 500! also Pimiga 2.0 shutters when playing games. tried 2x 128gb micro cards dunno whats wrong

[@ChrisEdwardsRestoration]

easily fixed, usually a 4k setup, jump on our discord and we can assist.

[@CubicleNate]

Very cool device! I am curious about performance between the IDE / CF / SD Card vs this SCSI device, do you notice an improved performance?

[@ChrisEdwardsRestoration]

Its roughly the same as the scsi bus speed is what it is

[@brostenen]

I have been thinking about such a solution for the SCSI VLB card I have for my 486-DX2-80 machine.

[@ChrisEdwardsRestoration]

indeed, as it is just presented as a device on your scsi chain. there is no need to worry that it wont show up. its just an ID, and you can configure it over the web for whatever you want that device to be.

[@DangerIsMyMiddleName]

Maybe because the CRT is interlaced? IDK. I am curious about your clock that shows the boing ball.

[@ChrisEdwardsRestoration]

Previous video divoom tivoo

[@theamigashow9506]

It's a shame isn't not quick enough for video drives. I had to buy the Acard interfaces to get quick enough speeds, pretty expensive :( But it's the RASCI looks like a another good general option.

[@ChrisEdwardsRestoration]

its as fast as your Scsi bus can push it. but you can have tons of stuff which is super cool

[@theamigashow9506]

@@ChrisEdwardsRestoration looking on other channels for SGI, it seems to max out at 4mb/sec.

[@Noweee]

@@ChrisEdwardsRestoration doubt it'll reach Phase5 PPC speeds though. I'd suspect a 5MB/s or something. Numbers are meaningless on their website for Mac related..

[@kjellmesch8060]

Hey Chris, any plans on testing the BlueSCSI V2?

[@ChrisEdwardsRestoration]

No the zulurp2040 blows that thing away. I made videos on it look for them on my channel. I have hundreds upon hundreds of things.

[@DAVIDGREGORYKERR]

What about using Cross-Pi on a IBM compatible running a 80586 with Code::Blocks as your IDE of choice to cut down your compile times down to just a few seconds.

[@ChrisEdwardsRestoration]

i compile it on the pi itself

[@theundertaker8273]

Have you tested network on the amiga ? Mean tcpip stack etc does it supports this ?

[@jjdigitalvideosolutionsllc5343]

Can you safely unmount/eject the RASCSI drive on the Amiga, using unmount from Aminet, without doing a reset? Does Amiga OS3.2 include an unmount drive feature?

[@ChrisEdwardsRestoration]

Depending on the drive yes

[@piyushkhengar]

Thanks to your video, Chris, I managed to get AmigaOS 3.2 running on a RaSCSI on my AA3000+! Here's what I'm trying to figure out next: how to get random files from my PC/Mac into a RaSCSI hard drive file? Or, how can I create a .hds image from a folder, stick it on my Raspberry Pi, and get the Amiga to recognize it? Is that possible with this SCSI solution?

[@ChrisEdwardsRestoration]

ive noticed its hdf format is not that of Winuae hdf. remember this was designed for a mac, I just used it on the Amiga, it works great. but they are basic hd type76 files for the amiga. copy the file out from rascsi to your computer, then open it in winuae (running as administrator) and it should load. you can then port it to whatever card you want for a real amiga boot

[@piyushkhengar]

@@ChrisEdwardsRestoration thanks, I’ll give that a shot!

[@piyushkhengar]

You are the best in the world, Chris! This did the trick for me. Thanks to you, I managed to update my installation to 3.2.1 using this method!

[@piyushkhengar]

Alright, one last question for you now that I've got this basically working: is there a way to get the Amiga to wait for the Pi to finish booting up? Right now, the Amiga boots to the KS screen, and then I need to wait for a bit, and finally soft reboot when the Pi is ready so that the Amiga can see it. Would be amazing to not have to do that ritual.

[@ChrisEdwardsRestoration]

Turn the rascsi on first? No mines the same way

[@Retrocomputernerd]

Are the long compile steps a one and done exercise? I.e. if you had multiple rascsi devices for multiple machines could you just image the micro sd from the raspberry pi and write a new image for subsequent kits?

[@ChrisEdwardsRestoration]

One and done per pi or image the card

[@unixyouth]

you can also get prebuilt images with all the necessary bits. Sorta plug and play

[@Hasse.Andersson]

uhmm Soon one could build a complete Amiga with Pi modules, nice then maybe I can have a "real" Amiga again... Nice Info

[@denniskrijnen5586]

Hello Chris, Are you able to configure a RASCSI as ID0 and boot from it? I found the boot time for the PI to be just to long for the Amiga SCSI controller to wait for it to be ready.

[@ChrisEdwardsRestoration]

You can make the devices it presents be any id or lun combo

[@denniskrijnen5586]

@@ChrisEdwardsRestoration Hello Chris. I did that and i was able to install OS3.2 (ID0) on it which booted after install, but after power down and up, the device was not found anymore. I suspect that the PI takes to much time so that the controller thinks there is no drive.

[@AlbertvanDuin]

About the DB25 to DB25 SCSI cable, is it just a straight cable, so pin 1 to pin 1 (etc.) ?

[@ChrisEdwardsRestoration]

Yup

[@AlbertvanDuin]
