SF-HD7 (Sanyo) can be found on some SCPH-30001R series consoles with GH-015 motherboard, (V5 and V6)... Some less knowledgeable folks here call it "open faced laser" or skull/barebones (caveirinha, here in Brazil) laser. In fact it's exact the same crap as the newer SF-HD7 lasers you see on newer consoles, but it has the older laser diode you see on 400A and 400B lasers.
It's actually a good source of good laser diodes for people who are into repairing laser pickups as because the SF-HD7 has a heavier lens assembly it cannot read discs good enough to allow one to play games with it if the coils are burnt, saving the laser diodes from longer times using overcurrent (the mechacon tries to compensate for bad efficiency on the lens coils rising the current for the laser diode). That's why you have good chances to find usable laser diode chips on these crappy HD7 lasers.
