Re: TF534 + Mem68k

Ok! I've read somewhere that it is sometimes necessary to daisy-chain autoconfig-out to the autoconfig-in of any following device. Is this only relevant if there are several devices on the bus and you wish to set the order of their configuration? I've explained this many times.. The Amiga doesnt se...

The onboard TF ram is always configured first.

Re: TF534 + Mem68k

No, it just seemed to work by bridging the "autoconfig-in" jumper to ground. To be honest I do not know in which order the Mem68K and TF534 configures their memory, but it did work. The 534 4mb ended up in Zorro3-space and the Mem68K filled Zorro2 with its 8mb. The one thing I had problem with thoug...

Re: TF534 + Mem68k

I believe they are obsolete unfortunately. I looked around for a while as well, then settled for used memory from random eBayer. The ones i found are KM416C4104AS wich were said to be "maybe compatible" for this. So far they seem to work perfectly.

Re: TF534 + Mem68k

I ordered 4 empty PCBs from that exact eBay-listing, desoldered memory chips some old sticks of DRAM and then assembled them myself. I still have 3 of them extra, but since the first one I tried testing worked first time I did not test them further. If you like I can test to make sure that the rest ...

Re: TF536 Experiment

I'd love to build one as well. So far i've managed to make working copies of all of your designs except the TF520. If someone finds a particular hardware/software combination (of A500 or ST) that behaves oddly, there is a good chance that i could build the exact same setup and see if it is repeatable.

Re: TF534 + Mem68k

Using a full MC68030RC50 and "cpu fastrom" i get 6.8-7.3 Mb/s! Not sure if those are 100% correct numbers, but navigating folders seems very snappy now.

Re: TF534 + Mem68k

I agree that longer pins would be better, this is how it looks with normal ones: IMG_20190527_164254_resized.jpg IMG_20190527_164335_resized.jpg Juuust enough length to make it work :) I made sure to fill the vias properly in both the 534 and relocator to get a somewhat durable connection. Do you kn...

Re: TF534 + Mem68k

The female headers are actually soldered to the Mem68k, upside down. Then i carefully adjusted the pin-headers connecting the tf534 and the relocator to get the maximum amount of height on the topside of the tf534. This meant that there was only around 1mm of pin header to solder on the underside of...
