TOS 2.06 Mega STe

Post by Fletch »

I received a TOS 2.06 upgrade kit for my Mega STe from Chris this week and am not having luck getting the machine to boot with the new ROMs installed. From everything I see on the web the HI chip is on the left and the LOW is on the right. Does this look right? Any suggestions?

Thanks!

Pete

Yeah that's correct.

What do you get when it tries to boot? What TOS did you have before and was that working?

How many pins did the ROM's have you took out ?

The TOS 2.05 chips I took out have the same number of pins as the 2.06 ones I purchased. I put the 2.05 ROMs back in and they work fine. Swapped the 2.06 in and out a half dozen times without success. I just thought maybe I had installed the ROMs incorrectly. Oh well, maybe I'll buy another set sometime and try again.

You can send them back for a re-test if you like, they are all tested before they are sent out and never known any not work in a machine.. I guess you could swap HI & LO just in case I stuck the stickers on wrong.

BTW - the pin on the left chip , bottom left, pin looks like its bent and missed the socket ?

I hastily reinstalled the chips to take the picture of how I had installed them. I put them in many times before this. So yes, in the picture the pin appears to have missed the socket, but not during use.

I will send you out a new set in a few days. Though I don't know why they wouldn't work, they are all verified before they are sent out.

Did you try swapping HI & LO ?

Chris,

The replacement ROMS arrived today and they worked immediately. Thanks so much for sending them.

I did try swapping them around on the original set. No go.

The new ones you sent are great though.

Thanks again,

Pete
