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.

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
