First impression

[Administrator]

Today I patched TOS 3.06 at two locations. You recognise them?
Anyway... some minor issues need to be settled before its status can be declared as "final".
Beta test is probably starting the next weeks.
TOS is 3.06 German.I can patch US, UK, French and Swedish, too.
Are there any other 3.06 around to patch this way? If so: let me know.

And now the screenshot - caTTerror V.1 at work:

caTTerror V.1 top view:



First Benchmark (yet without read-burst):

[Administrator]

Latest addition is ReadBurst mode for TT-RAM. Benchmark gives a 15% improvement:



Original Atari TT-RAM card as comparison (non nybble mode):



And Magnum TT:



You can see that it does not use ReadBurst at all.

A MightyMic TT gives 14.2MB/s in reading but I don't think I can squeeze anything out of the CPLD anymore.
But... hey... that's just 3% difference

PCB needs a little rework and if there is interest then I will start a batch of PCBs.

Is there any interest?

Edit: I think the VHDL code has maxxed out in terms of performance with DRAM now. Same performance as a MightyMic32B

There doesn't seem to be any interest at all. If so then I will populate my PCBs and use them on my TTs. I'm not gonna spend some hundred bucks on PCB manufacturing to let them get spoiled on my shelf.

I can't say I'm not interested, but I have too many open fronts right now.
The TT it's the latest Atari added to my collection, and I'm not doing anything right now with it, so if you have a spare one, well, perhaps we could talk some day.
As I said, too many Atari things on my hands right now.
But, I have to say, I'm impressed and I have to thank you for all your work on the Atari systems.
I feel envy of your minds.

Regards.

New PCBs arrived saturday.



Will try to populate them the next weekend and see how they perform.

Did i see correctly?

128MB RAM on a TT?

Yes. I used one 128MB SIMM.
That was no problem with newer batches of aixTT or Magnum TT cards before (16, 32, 64 and 128MB SIMMs).
With caTTerror you can mix any combination of with 4, 8, 16, 32, 64 and 128MB SIMMs.
AND you get two IDE ports for up to 4 devices. No need to buy expensive IDE<->SCSI interfaces anymore.
Thanx to pakman's (he designed the PAK68/3) TOS patch you can boot from an IDE device.
My TOS patch corrected the number shown at the end of the TT-RAM test. With standard TOS 3.06 and more than 99999KB you get some garbled output.

very very good!

i would say this is a muST for TT owners (í´m not one).

pity the MegaSTe design is not a little more similar to the TT or this would have a much bigger market!

[vhenares]

I am interested in this project. I would like to know price and availability.

Thank you for you job, is very interesant.
