Hitachi ARM ROM Programming Warning

Just a warning to anyone who's using a recent version of PC-3000, the ARM ROM programming doesn't work right. I used it to attempt programming a Toshiba branded 7210DLE6 ARM family drive, and it just bricked the PCB. ROM transfer confirmed that the original ROM code wasn't the issue.

I removed and externally read the ROM, and this is what it had written to it:

View attachment Botched PC-3000 Write.BIN

It looks to me, like it only wrote a little bit of the ROM code into the middle and filled the beginning/end with FF FF instead of actually using the whole ROM code that was read from the original drive.

Fortunately, I was able to get a full recovery and unbrick my donor PCB using the external programmer as well. Thank goodness I always back up my donor resources before I start anything.

This has already happened to me some time ago. I contacted ACE about it, but it seems the bug continues.
We have to "remember" them again.

This is something I discovered pretty quickly working with a 5475A9 ARM case. I also ended up using my external EEPROM programmer/reader on this one.
