1040 STe

Go to a junk PC recycle store and get any 1MB 30 pin SIMMs. I would make sure all 4 match.

 

If you need TOS 2.06 let me know! Its a simple chip swap, great upgrade while you have her cracked open.

Cool, I'll run SysInfo. TOS 2.06 I'll tel you know!

My STe came in thing is a beast and the best part it looks like it's new! I'll have play with later to night to see if has 4MB.

[walter_J64bit]

I've just ran Sysinfo I've got tos 1.62 :thumbsup:

The STe has Total ST-RAM 4096 kbytes so that's 4MB right?

[Rybags]

4 meg, right.

 

I was also happy to find mine already had 4 meg, although I've got an older TOS... might have to see about getting someone to burn 2.06 for me.

That's not bad... can you produce a UK version though?

Yes no problem.

I have some old TOS chips from a 1040STf can they be re-used, to have TOS 2.06 installed on them?

Nope, those chips are too small.

Also, I'd first check whether your ROM chips are socketed and whether the sockets are larger than the chips. TOS 2.06 is provided on larger chips (32 pins vs. 28 pins for TOS 1.06/1.62) and I've actually opened STEs that only had 28-pin sockets soldered to the mainboard (they can be replaced, as the solder points are still on the mainboard, but it's much more work). Similarly, in several STEs there are no jumpers, but 0 Ohm resistors. These can be cut off and replaced with small pieces of wire soldered appropriately.

 

And if you have already opened your STE, you should check whether the DMA chips are the properly working ones, since if you don't have them inside, you should never write to a hard drive connected through the DMA interface (an IDE drive will work, of couirse, as will reading from DMA devices). It is very likely that a 1.62 machine has the good ones, I guess, but as Atari never admitted that the older DMA chip doesn't work properly in the STE, there surely are thousands in existence with DMA issues.
