These things are kind of open:
- the PPI/key_ghosting_sgc_protected tag
- check on PPI/code_kana_locks and PPI/graph_locks tag
- VDP I/O port mirroring
- serial number of the machine we're basing the config on (for reference)
- Z80 type or other IC's types when they're different from the pics on the MSX.org wiki
- ideally: an EPROM dump of the ROM chip

Photos are here.

CAPS/KANA lock (led in the key)
Serial: 205243
CPU: DA780C-1
VDP: TMS9118NL
Engine: S3527

I will check ghosting on HB-10 and HB-11 (HB-10 also seems unconfirmed). HB-10 config mentions discrete PSG but it has S3527 so that config may need some recheck.

The HB-11 firmware includes an easter egg (S+P or Y+P during boot), a hidden text "A Yellow Panther Production MCMLXXXV", and 7 alternative MSX-BASIC fonts (CALL FONT (n)).
