X-MASS, a mass-storage expansion for all CPC.
« on: 19:32, 14 December 14 »
Hello everyone,

Most of you already know that SyX and I are working on a mass-storage expansion for CPC.
X-MASS embeds a 128MB flash drive that allows to store thousands files.
Here the picture of the final board! :)

13431-0

Users can access it from BASIC using the ACMEDOS ROM. RSX commands allow to browse folders for storing your files.
Developers will be able to work on ambitious projects requiring megabytes of resources and code, breaking the floppy limitation!
Last but not least, X-MASS is natively compatible with SymbOS and BDOS.

1- Preorder X-MASS here: CentPourCent [dot net]
2- Download AcmeDOS here: AcmeDOS ROM
3- FW3.1x users must update it here: FW3.1x ROM


I will try to add informations to this post if you ask questions.   ;D
I would like to thanks gerald for his precious help and support.  8)

Q: What is the X-MASS storage form factor?
A: A 44 pins auto-powered disk on module.

Q: What is the X-MASS storage capacity?
A: 128MB. You can store several[nb]It's the capacity of around 350 double-sided DATA floppy discs.[/nb] thousands of files on it.

Q: What is the X-MASS speed?
A: 160K/s (1.300.000[nb]+6.532 bauds exactly. That is more than Tape speed. XD[/nb] bauds for 464 users) and no drive delay.

Q: Is the X-MASS work on all CPC?
A: Yes. But, it require a ROM board to use it from BASIC.

Q: How to use the X-MASS from BASIC?
A: The ACMEDOS ROM mount it at boot and add new RSX commands.

Q: Is X-MASS use a custom file system, like BDOS does?
A: You can. But ACMEDOS allow you to use a PC FAT to be accessed independally from BASIC or SymbOS.

So... If it's called X-Mass, and If I already ordered one I guess I can expect it within the next week? :)

Otherwise: yeah, new hardware!

A dream becomes true, thank you so much for that awesome piece of hardware. I am totally happy, that it is working with BDos. I do have some older DOM Modules with higher capacity here (512Mb / 8 Gigabyte). Is it possible to change the 128Mb DOM to a 512 Mb or 8 Gbyte Version? Are there any limitations of the DOM Module?

However, i have preordered and i am thankful for any piece of new hardware for CPC. Thank you for that work!

Regards
Tom

I need to do more tests before answering to you. For information, it's a 44-pins connector.

Hi,


Probably a stupid question, but where could we find the ACMEDOS ROM to download ? ? ?


I know it's most likely to be of little use without this hardware, but it could be nice to have a look at it before we do get access to the real hardware.
(I have ordered the complete hardware set earlier today  :D Guess if I'm looking forward to getting later)


Looking forward to hearing from You.


Yours

The ACMEDOS will be available at the bottom of this page when all the software side will be finished.  ;)

What about the transfer speeds, how fast it is?

No precise benchmark was done, but it look to be around 10 times faster than a floppy drive.
As I know, the CPC expansion bus is close to 180KB/s ... So, it should be limited by that.
I will add this information when a program will allow to test it.  8)

My guess was that, the limit might be imposed by the speed of the expansion bus. I suppose that there is no way to go beyond that limit  ;D
