Re-add SASI Functionality #809
Comments
If somebody wants to re-add SASI support, this is how it should be done:
|
Here are my direct use cases: My understanding is that GIMONS' original RaSCSI was for the X68k. I understand he isn't involved in the project anymore (no need to rehash this). X68k is still relevant to me.
Finally I have several Sony/Panasonic/Pinnacle Micro 650MB MO drives, which are SASI and sometimes lived behind a (fairly buggy) SASI-SCSI bridge. Quirks of these drives from oddball controllers mean they often don't emulate right purely on SCSI buses, and in one instance I have one connected directly to a SASI controller. Would be good to replace it, it's an increasingly unreliable mechanism. I suspect others may have a need for SASI (ACSI) support for Atari machines. |
Adding a link to the Xebec controller that was often paired with the Plessey SASI PDP-11 controller I have: https://deramp.com/swtpc.com/SASI/XEBEC.htm |
@wohali Regarding Ataris, what you need is SCSI support, for both ACSI and SCSI. I am using RaSCSI with a MegaSTE (internal host adapter), a TT and a Falcon. |
I'm owner of two X68000 PRO and they are SASI. I see the removal of SASI has a very bad move since you deprive us of the possibility to use your version of RaSCSI (which is open-source) for those X68000s with SASI (that is, models under XVI). |
Are you using this fork of the RaSCSI software?
The previous release of RaSCSI still supports SASI, and is available for download. There are archives of GIMONS's original code available from multiple sources (including archive.org). None of the developers have access to a X68000 (yet). SASI functionality was broken for several releases and no one noticed because we don't have a way to test it. The plan is to re-add this capability in the future. If you have a X68000 that is available for sale at a low price, or if you are willing to volunteer time to test/troubleshoot/support the SASI functionality, it would help us get this functionality re-added sooner. Please keep in mind that we are all volunteers and doing our best. Please take this ticket as proof that we have not permanently removed this functionality and have intentions of adding it back in. |
@wohali When did you last use The |
It was prior to Aug 2022. I can attempt again in December - booked out the rest of this month, I'm afraid. |
We may be slow, but we haven't forgotten the x68000 community! (See previous comment about volunteers :) ) Last week I purchased an original Sharp x68000 and am trying to "learn" it. (If I knew Japanese it might help) So far, I'm able to boot the device using a Human 68k version 3.02 image. It seems that basic communication is working with the regular SCSI functionality in PiSCSI. I haven't been able to launch any games from the HD image, but that could be user error, or I just might not have enough memory. (This is a very basic, original machine - I think with only 1MB RAM). This ticket hasn't died, it has just been a slow process for me to track down a x68000 to tinker with. |
Hello, I have recently bought an x68000, I would like to be able to buy the pcb to assemble and carry out tests until it works correctly. Could you tell me where I can buy the PCB alone. I have pytho experience to help. thank you |
@jjlopezg Everything you need to know is written on the landing page of www.piscsi.com You either buy a kit from one of the resellers, or produce your own PCBs via a PCB manufacturer. |
Info
The team has removed SASI support from the current PiSCSI code. The current design/architecture makes it very difficult to make changes and has substantial maintainability impacts.
This issue is to gauge interest in SASI support.
How can you help?
If you are interested in having SASI support re-added into PiSCSI, please leave a comment with some information so we can understand your use case. Some info that I would like to collect:
Feel free to add duplicates to the comments chain. Or, if you use multiple systems, feel free to add them to the list
How else can you help?
If you are in the continental US and have an extra SASI host that you are willing to part with for a reasonable price, feel free to reach out to me on discord.
