The Buddha 20th anniversary IDE controller

[Motormouth]

What did you think about the Buddha 20th anniversary IDE controller from Jens?

What kind of speed do you get out of in an A2000 or even a3000 or A4000

How does is compare to a generic zorro II
WD 33C93 based scsi control like GVP
or 2091, or even the A3000 internal one

or a AMD 53C80 based scsi like
a trumpcard pro
or AdScsi?

With the scsi one ones I only get about 2,700,000 byte/sec even with a fast processor upgrade (like a vampire)
Even with CF cards.

Are their any other Zorro II options out there anymore?

From iComp webpage ( https://icomp.de/shop-icomp/en/produkt-details/product/buddha-ide.html ) ......

Performance: Even with slow devices, transfer rates of 2.2 MBytes/second(*) can be achieved. The raw transfer rate is only limited by the Zorro-2 bus, which is 3.58 MBytes/second.(**)

(*): measured with the classic "Quantum Bigfoot" harddisk
(**): performance depends on installed accelerator. Maximum transfer rate can be reached with 68020 and 68030 CPUs.

So, I suppose if your accelerator is reaching max transfer speed, complementing the Buddha, you could reach a transfer speed of 3.58MB/sec on the ZII bus. I would think that there are a lot of factors (software, drivers, patches) in play here.

I haven't done any speed test comparisons yet but, last spring I did finally get a test A2000 unit freed up for just this type of testing along with a few different accelerators (P5, GVP, TF) and disk types (CF, DOM, TruIDE). I was ready to start testing explicitly on Buddha xfer speeds but the A.org migration came up and then summer kicked in. Maybe do a search here as there were some very good discussions about the new Buddha board last spring. Winter's coming though!

I also purchased IDE4 Zorro 2 board to compare. So this board is also an option.

Also purchased a Z500 ( http://www.robthenerd.com/projects/z500 ) to perform the same testing on an A500 but I was in search of an A500 keyboard (these have dried up completely) so guess I'll have to spring for one of Kipper2K's replacement keyboards ( http://amigaonthelake.com/blog/-preorder-today-new-replacement-keyboards-from-kipper2k-/ ).

Now I just gotta get off my arse and git-er-done & post up! 

Thanks for the reply
I use to get 2.1 Mbytes/sec on my GVP SCSI even with 68000 as long as I had 16 bit true fast ram in the system.    So the 2.2 Mbytes/sec is on par with this.   

It is just that the buddha still cheaper than buying a SD-To-SCSI adapter and you can not buy the Mechware Card readers anymore.

I did not know about IDE4 zorro 2 board, a nice comparable to the Buddha.


Again thanks for the very useful reply.
