]2.[/color][/b] Fully working 8163B. Tiros & wenid both have fully working drives, using exact copies of the firmware or at least firmwares binaries that are the same.
The points used are the same from 8050L
8163B End of Cable Description
Eject ============================= pin4 Eject
TP126 ====1k resistor ============= pin6 Ready (uC pin50)
TP055 ====1k resistor ============= pin7 Tray_in (uC pin65)
TP128 ====1k resistor ============= pin5 Tray_out (uC pin49)
I did the following to get to the same point as Wenid and Tiros
1. Used this wiring with 1k resistors on all wires(even eject)
2. Modded the windows flasher as per Skyhi's earlyer post
3. Extracted the dld file from the modified windows flasher(20a58-62680)(269352 bytes in explorer/properties)
4. Put it on the hp dosdisk i made(see earlyer post)overwriting the standard dld file
After throwing this together i tested for a while and it seems to work 100%, ofcourse without cd/16x support(but the reading is quite fast anyway)
Maby this is interesting to the people who don't want to read origionals and want cd/16x support:
Tiros mentioned the led in front of the drive, i was looking at the same thing earlyer, it doesn't go out after the drive spins down, so that could be a much better alternate ready signal without problems with spindown.
After the mod above it came apparent to me that the origional and the fully modded 8163b do spindown, but they keep the ready signal high.
This hasn't been tested yet, but maby someone wants to take a look at it.
