DO NOT USE MOBILE / CGNAT DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

TOS 1.04 Upgrade for STFM C070523 Rev D

Post by ChrisA »

Hi,

Hopefully an easy question on my STFM before I order the 1.04 TOS upgrade. Am I correct in thinking my board has the 6 ROM TOS chips under the PSU (on the left) and are not the two larger chips next to each other under the floppy drive (on the right)? - I don't see HI and LO written anywhere.

Here's a picture of it to aid diagnosis.

Thanks,
Chris

You have "6 chip TOS" on that board. Yes under the PSU.

Wow :shock: That was a quick response. Thanks very much. I figured everyone would be in bed now. I'll order the ROM upgrade at the same time as the RAM upgrade. :D
