Okay the ROM is there, maybe an issue with the ROM itself or the surrounding logic. Also the cap next to the VDP is leaking...

I have an Spanish HC-7E. I can confirm the BIOS is the same as the HC-7GB BIOS that can be found online:

C: ... >fc /b hc7ebios.rom hc7gbbios.rom
Comparing files hc7ebios.rom and HC7GBBIOS.ROM
FC: no differences encountered

The capacitor is NOT leaking they glued an isolator on top, the "HBI interface is resting on it".
Your Hb T600 has some modifications the second drive connector is added.
The ram is expanded to 256 kB
It lacks the correction board.

I have this HBP-F1C (not yet unpacked). It comes with the disk so I can dump it, the Wiki says a ROM dump is also needed. That would require the ROM to be removed and dumped from a programming tool, right? Or can it be read via the MSX?
