SIG X68000 / Re: RaSCSI :) stuck in set up proceedure, please help ???
« Last post by Ex68Kay on May 22, 2019, 09:03:04 AM »
I apologize for my ignorance but to be fair I never used a Sharp X68000 emulator let alone an actual unit before.
I did everything in the first reply you posted and it isn't booting into the image when the X68000 is plugged in. It Shows a SASI in HD0 and nothing in the rest of them then asks for a disk. I have a Master Floppy so I changed the Boot in by using the ui prodivded with switch.x, i changed it to boot hd0 and the ram option ed0100 or something. How do I get it to work?

Well I've found the assemblergames topic mentioned earlier, that helped me to get some directions.
I understand I do need another programmer, with Usbtinyavr preferred over Usbasp, because apparantly that last one has the risk of another programmer needed to program the programmer for my programmer (I have once watched Inception and felt the same).

I'm not sure if the pin headers that come with the Tinyavr can just be plugged into the programmer, or if I need something else to make that happen. I'll order some extra headers in case I need any (and hoping to get the correct size).

Guess I'll have to try to find out how to use it when I get it (and what to do with those "fuse bytes" mentioned?).
This is quite a trip.

So I've received all the needed parts to get soldering. But reading all this through, there's one thing I don't really understand.
I see I need to flash the programmer with firmware first, but how on earth do I do that? Do I need a programmer for my programmer? And if yes, which one? Any cheap Aliexpress/Ebay Chinese option available?

Googling about this I read that ISP means that you can program your chip without taking it off the board, I don't read though how that is done.
Also, can I just start soldering now and flash afterwards? Or would there be more and cheaper chip programmer options available if I'd program the chip before soldering it to the board?
I've recently ordered a PIC programmer from China, but I assume that's something totally different?

Many n00b questions I guess, but hey, I need to start somewhere  :D

Yes it's worth doing and extremely simple. The commands I provided setup the scsi bridge on 1 and you just need to install the driver.

First copy rascsi145/bin/x68k/RASDRIVER.HDS on to the raspberry pi. Then use rascl to mount it:
Code: [Select]
rasctl -i 2 -c attach -f /wherever/you/put/RASDRIVER.HDS
Boot the computer and it will show up as drive B:\
Copy it to A:\SYS
Turn off the computer and detach the driver hd image:
Code: [Select]
rasctl -i 2 -c detachTurn the computer on again and edit A:\config.sys and add the following line at the end:
Code: [Select]
DEVICE = \SYS\RASDRV.SYSReboot once more and it should now show up as drive D:\ and the root of the raspberry pi. Now you can just scp files to the rpi and use LHES to copy them into the computer rather than deal with any form of media.

Thank you I will try that later very well.  :) 8)
Did you ever set up the RaSCSI to display the RaspberryPi directories on the X68000? Is that worth doing? It seems easier to just fill the Pi with x68k stuff and just run it from there however I am not sure it even works that way but probably can.

It's likely the location of your HDS vs where you are running the command. Rather than do that here's my setup for rascsi:
First setup the general folder for where your images will live:
Code: [Select]
sudo mkdir /var/rascsi
Now move the binaries for your board to an area that is within your path. I used /usr/local/bin. BE SURE TO USE THE PROPER BINARIES FOR YOUR BOARD! If it's a big green thing that says gamernium obtained from booth you're in the right spot.
Code: [Select]
cd /home/pi/Documents/rascsi144p1/bin/raspberrypi/gamernium
sudo cp ./* /usr/local/bin

Now move your image to where your images are supposed to live, this is where you're having an issue - you're in /home/pi/Documents/rascsi144p1/bin/raspberrypi/gamernium and I'm going to guess that X68000_V4.HDS resides in /home/pi/
Code: [Select]
cd /home/pi
sudo mv X68000_V4.HDS /var/rascsi

Now try to mount the image
Code: [Select]
/usr/bin/sudo rascsi -ID0 /var/rascsi/X68000_V4.HDS
If this works congrats, you have your layout setup properly.
run the command "nano /etc/systemd/system/rascsi.service" and put the following contents in it:
Code: [Select]
[Unit]
Description=RaSCSI
After=syslog.target

[Service]
Type=simple
WorkingDirectory=/home/pi/
ExecStart=/usr/bin/sudo rascsi -ID0 /var/rascsi/X68000_V4.HDS -ID1 BRIDGE
TimeoutStopSec=5
StandardOutput=null

[Install]
WantedBy = multi-user.target

Press ctrl+x, hit Y, enter to save the file.
Run the command "sudo systemctl enable rascsi" and it will now auto-start on boot up. You can then use "rasctl" to interact and no longer need to use sudo. I also placed scripts in /usr/local/bin to allow easy switching between pc-98 and x68000:
Code: [Select]
pi@rascsi:~ $ cat /usr/local/bin/pc98
#!/bin/bash

for i in {0..7}
do
rasctl -i ${i} -c detach
done
rasctl -i 2 -c attach -f /var/rascsi/pc98-hd.nhd
rasctl -i 1 -c attach -t bridge
#rasctl -i 1 -c attach -f /var/rascsi/pc98-games.nhd
pi@rascsi:~ $ cat /usr/local/bin/x68k
#!/bin/bash

for i in {0..7}
do
rasctl -i ${i} -c detach
done
rasctl -i 1 -c attach -t bridge
rasctl -i 4 -c attach -f /var/rascsi/x68000_human.hds
pi@rascsi:~ $

With those I now can just type "pc98" or "x68k" to auto-switch setups.

Also to note using id0 might be "iffy" as it is usually reserved by the system. This is why I'm using 4 for mine and 1 for the bridge.

SIG X68000 / Re: How do you get the large 4gb/900mb hd images workin?
« Last post by sampson on May 19, 2019, 12:39:04 AM »
x68000 only supports up to 2 1GB partitions per drive with one being active. You can use GOVERHD to combine the two partitions into one however I've heard it's not very stable. You would need to use separate 2GB drives on each ID.
