Data Center Discontinued?!

Post by guddler » Mon Jun 10, 2019 10:01 pm

Just noticed that Mark appears to have discontinued the Data Centre. Sorry if this is old news!

I don't actually need one, fortunately I already have one but I'm quite surprised to see this. I guess parts eventually run dry or some such. The website says to email for news on other USB storage options. Any idea what they might be? Again, just curious, not in the market for something.

USB storage option is Gotek.

DC is now open source, Mark used up supply of Xlinix chips DC was based around, and wasn’t worth re-engineering as he now sells lots of gotek.

Updated hardware list a while ago.

Oh that's a shame since a Gotek really isn't a replacement - no IDE / HDD / ADFS etc. But, obviously understandable if parts had become a problem.

I have a limited supply of the XC9572 (100). The number actually available will depend on how many more AP5s I decide to build.

Edit: But I believe you can still obtain them, at a price!

BeebSCSI or Dominic's pi zero based implementation are a better option for HDD (no need for patched ADFS). Couple those with the gotek/FlashFloppy and you're laughing.

I was not aware it was discontinued either, although I've not really been keeping up on 'current news' generally I'm about a couple of years behind the newest developments. Only just really looking now at Pi Co-Pro's etc :o :D

Hi,

I seem to of missed the boat onn the Datacentre and BeebSCSI, but since thry are all open source, I am thinking about making some for myself.
Regards,

Derek

Don’t think any one has built a DC from scratch yet (well apart from Mark at Retroclinic obviously). Lots of beebscsi’s been Built. If you had a beebscsi and a then a gotek, (edit: iPad ate some of the text) as Daniel says, you don’t really need a DC.

Of course if you do go ahead and build a DC then everyone will be interested on your progress.

The beebscsi is probably cheaper (the pcb is smaller and less components) *but* look at dp11s pi zero beebscsi solution. That is much cheaper.

Very true. Also dp11’s has no surface mounts if I remember correctly, another on my list to build at abug in a few weeks.

I missed that too that DC was ended.
Glad I have one though. And very happy with it with all the data ai have.

It's also worth mentioning that BeebSCSI was designed from scratch to be an open-design; both the hardware and the firmware in the solution are fully documented, not just from the user's perspective, but also from a technical implementation too. Plus BeebSCSI isn't a patched IDE implementation with limited storage per card; you can have hundreds of gigs of storage from a single microSD card.

The open-source core of BeebSCSI (the Acorn Winchester SCSI emulation that works with the original Beeb and Master ADFS (and Elk)) is also the core of the Pi Zero implementation (it's documented open-source, so it positively encourages porting and extension).

BeebSCSI is also a lot faster than IDE solutions - the SCSI implementation (usually) runs as fast as most RAMFS operations; but provides a lot more space.

BeebSCSI also supports VFS (when connected to the internal 1MHz bus of the Master) - the emulation is very accurate; it can even boot Domesday.

Hi,

Well thinking what I have to make, which is Electron ATI, EUPRS, I probably do need a Data Centre or BeebSCSI.

I just carried along with all the excellent hardware projects.

At present I more things to do now and can not find the time, not working either...
Regards,

Derek
