Terrible Fire Accelerators

[alenppc]

Don't take my IDE report at face value yet, I think I might have messed something up. I am going to check it again tonight after work.

I need to find a 50 Mhz crystal too. Will 60 do? I guess that might be too fast.

A couple of pics attached for the curious.

I’m using a weird 35.128mhz crystal at the moment. Rather odd but I got a lot of them v cheap.

60mhz may work but it will push the RAM too fast. Will produce a 1WS ram firmware into the bundle. Don’t expect more than 1WS will be required.

Guys where can I can the Terrible Fire TF534 board from....

Come on dude at least read the last few pages of the thread :/

@hooleydog
TF534 is in prototype phase, only for betatesters atm..
Or You cat try to ask Clad, he has seen someone is selling them on Ebay...

@Stephen & alenppc
sorry guy's, wasn't able to test new FW sooner - was really buzzy..

well.. latest Alpha FW (from 10.10.18) seems to be messed up - ide isn't working for me at all.
both ALPHA & ALPHA2 from 10.07.18 are working fine ide included on A500,
doesn't work on A2000 - hangs in reset loop
haven't tried higher frequency yet - can try to swap oscillator to 50Mhz - still have them here

Update
Card is not happy with 40Mhz oscillator - not working

Thats consistent with what i'm seeing and alenppc's experience too. Thanks

I have a weekend free from Gaelic classes so I'll have a go at solving the the issues this weekend.

[8 Bit Dreams]

will be very appreciated, will test if something new comes up @ weekend.
For now i'm on FW10.07 Alpha2 and 24Mhz - no issues, no glitches on A500, WHDload works..

i am still thinking about differences between E Clock @ A500 & A2000, i do understand what You said about it, but maybe something acts as a delay for it, and CIAs getting confused, hence it hangs in reboot cycle? It may be also the IDE issue, or ram isn't happy.. Does this firmware has waitestates?

On A2000 it acts as follows: it reboots, then actually IDE activity should start, but i doesn't happend - then it just reboots, and this happens in loop..

garlic classes ummm tasty.

The Gayle issue should be different from the CIA issue. If we had CIA issues i'd expect floppy drive issues and timing issues. Both check out 100% on DiagROM/Systest. It doesnt mean its not an issue but CIA is realistically nothing to do with IDE. CIA's main purpose during boot is to disable the ROM overlay. Which according to DiagROM it does fine.

A reboot loop usually indicates a ram issue. I recommend wiping the RAM CPLD to verify this.

Finally if the Gayle emulation is telling the Amiga there is a card device present then that could cause a hang while the amiga waits for the PCMCIA card to respond. Seen this before but the testsuite says this isnt happening.

I've dismantled my LA to reverse engineer the NIC card so others can have that functionality.. it will be open source. Needs put back together before it can be used for testing.

Wow. How is that even possible? Some's leaked the gerbers or whatever? Or a beta tester has shared them?

Weird.

Not unless someone has hacked my laptop. Even I have a tough time finding them on my own machine.

The only board that was shared and not built was one I gave Mark (supaduper). He's perfectly entitled to sell it but anyone building it will get zero support from me.

Can a 534 compatible board be 'generated' from a 530 perhaps the way people have added 4meg to the 530 instead of two?

Maybe people are selling 4meg 530's as 534's?

[hooleydog]

I haven't seen any T534 boards on eBay (T530's I have)...

[8 Bit Dreams]

..i think Clad has mixed up 530 & 534 lol
Have checked ebay right after his post - nothing found, so i wrote it as a joke

This is not possible, we got a pcb from Mr. Leary, not gerber files. Mine came with KEL connectors i've bought for 3660

@Stephen
By the way, do You still have some KEL's for sell? I'm interested in 4x

I don't think someone will do it.. too much differences

About 4MB TF530 - this is possible, see older posts in this thread, however this needs a special firmware, will not work without

I do.. around 30 left. Best to email Mrs TerribleFire at the sales@.... email address you paid to last time and she'll do all the work. She usually ships same day.

I also have a line on whats going on on the TF534.

It seems that the machine is locking up during some kind of DMA cycle. Its tough to know exactly what address its accessing but I think its address 0x000934 (I consistently see that on the scope but it could be the conflation of 2 addresses).

I didnt have a lot of time with the LA to examine things deeper but it looks like I may have screwed something with the BG/BGACK signals. Does the A2000 use these for floppy? I've never seen them asserted on the A500 (and that would explain why the A500 works and the A2000 is not working).

Maybe @Toni Willen has seen something like this. On my Kick 3.1 ROM it sits spinning at @0xF81476 until DMA kicks in then it gets stuck with no CPU control lines asserted at 0x000934.

More tomorrow. I suspect its the bus arb.

Oh!
That is very interesting! Would be great to see a stream and chat about it!!!!

[hooleydog]

Guys, is this board for Amiga???.. If so Steven do you have the BOM and firmware Pretty Please (A fellow Brit)....

At the moment i'm struggling to get time to stream. I basically figured i could get work done or stream.

In fact I put in wifi controlled smart plugs so i can use my rig remotely. So even though im working im not in the lab. I'll try and make one at the weekend though.

[alenppc]

Ok, I can confirm now the IDE is not working. Same behaviour as described by Stephen: blinking led and then lockup
