Re: 68060 sources

Wish you best of luck, if even if you get close to what you achieved on the TF cards it will be a big success. I am an embedded software guy, the Cortex-M7 cores with big 16k/16k caches really perform well, I wonder how much of an architectural change it would be to up the cache to drive some extra ...

Re: 68060 sources

Ok, don't realise it was for 060 compatibility, thaught it was to get 060 performance without finding the golden nuget that is a real/full 060.

How many extra instructions does a 060 support beyond the 020 ?,.. I guess the 060 FPU is a subset of the 68881/2 as well.

Re: 68060 sources

My information based on https://www.mike-stirling.com/2020/03/a ... m-sd-card/

Results against 040 show it's pretty close to what an 060 would do, and that's on a pretty standard/cheap FPGA.

Re: 68060 sources

Hi, The 060 and even the 030 designs are complex, that's because due to manufacturing process limitations you had to go complex to get performance, caches, pipelining, etc With modern FPGAs the 30 years of process improvements means we get clock frequency for free. So you don't need complexity to ge...

Re: TF536 Sales Suspended

Seen boards on ami/eBay for £150 ish, probably cost me close to that to build my own, throw in a few fake 030's and it's about the same.

Pretty far away from the £400 Blizzard B's are going for.

Re: TF536 Sales Suspended

Guys like Rob Taylor who did the A500++ and C64 boards setup a Tindie store, the think whatever the cut Tindie take is worth it to have a middle man.

Just an option, try not to take the stupid people to personally, it's just 3% of society.

Re: TF536 Sales Suspended

Stephen, you've done a great thing for the community with the TF boards, pitty the few with a lack of self control spoil it. If your willing to take the advice of a stranger, get out of the direct sell, it's to much hassle, plenty of guys running stores would be happy to do the customer facing stuff...

Re: Wow Just upgraded from a TF534 to a 536

Similar plans, ZZ9000 in dispatch from MNT. Should be fine as they have tested with Zorro II systems. But fingers crossed.

Re: Board file available ?

That was a pretty schoolboy mistake, viewed as raw and saved, now can view ok.

If I mirror the view in OBV and then rotate 270 it pretty much lines up, thanks.

Board file available ?

Hi,

There is a tf536r1_openboardview.brd file but it does not seem open in the few free viewers I used (including OBV)

Does it need Cadence or Allegro ?, also is there a V2,.. just want to check my pin1 is correct for the ICs.
