Re: ST536 in a Mega ST4

As I said before, IDE causing a crash can only really be false IDE access when there isn't supposed to be one. Likely a bad solder joint on your PLD,. I assume one of the address lines or IDE control lines.

Re: WANTED - 1MB 100/120ns simms 30 pin

Just tell me what you want and I'll send them - but I don't have full sets of the 1MB ones :( Looking again there are 5x 120ns 1mb Simms. So that should be enough to test what I want I think.. I've been looking around the internet and there is basically nothing about unless I want to pay $50 a stic...

ah, I've not woke up yet, didn't notice there wasn't full sets. Let's hold for now and see if I can find some other odds ones to make up the set first...

Re: WANTED - 1MB 100/120ns simms 30 pin

Oddly 120ns 256K simms failed to detect the full amount. But 150ns found the full 1024K and seemed OK. So it must need the full 4MB to show the problem.

So @troed , if I can borrow/buy/swap your 1MB sets then I can give them a try.

Re: WANTED - 1MB 100/120ns simms 30 pin

These are all SIMMs I have with those speeds if you can't find better matches. Cool!. Think first set is a 256K simm... but I didn't actually try 256K simms.. EDIT: Unfortunately, they are all 70 or 80ns rated apart from four sticks which I believe to be 256Kb SIMMS that are 150ns. ah thanks for lo...

Re: WANTED - 1MB 100/120ns simms 30 pin

ijor Do you know how the RAM is organised. I mean I'd assume when 2 simms are in place, the RAM is literal from 0-2MB. But when there are 4 simms, is it still literal from 0-4MB ? or does the RAM get interleaved, so it would use 1 word from bank 0, then 1 world from bank 1, then 1 word from bank 0....

Re: WANTED - 1MB 100/120ns simms 30 pin

BTW, Im going to have a good look for the SIMM box tomorrow (when I can bang about without consequence!), so Im still on the case with this. :thumbup: However...80ns is 12.5 Mhz, so something thats 100-150ns is in the ~6-10Mhz range...250ns is 4Mhz. These are very early SIMMS and I would have thoug...

Re: WANTED - 1MB 100/120ns simms 30 pin

So parity is preferable but its more the speed of the RAM which is going to be the main issue it seems. Same brand of simms per stick is preferable but likely not that critical either. So I basically need. 4x 1MB simms 100ns,120ns,150ns. I have to have the full 4MB set of all the same speed ratings....
