Yes there are quite a few, I'm not sure where the PCB part number is so I'll give you various things and you can tell me if I got one you can use :-) The MAXTOR chip is marked 'B73ED', There is a covered chip marked 9211 and R140. There are 39 Jumpers on this drive, Mine are set as follows: Jumper State JP1 on JP20 on JP2 off JP21 off JP3 off JP22 on JP4 on JP23 off JP5 on JP24 off JP6 on JP25 on JP7 on JP26 off JP8 on JP27 off JP9 on JP28 off JP10 off JP29 off JP11 off JP30 off JP12 on JP31 off JP13 off JP32 on JP14 ?? JP33 off JP15 on JP34 off JP16 off JP35 on JP17 off JP36 off JP19 off JP37 on (between JP2 and JP3) JP38 on JP39 off On the JDS1-7 pins I've got a jumper on JDS1 (presumably this selects it as drive 1) No other identifying marks as far as I can see... Any help appreciated. --Chuck At 10:46 PM 3/5/99 -0800, Don Maslin wrote:

Did that first, but not luck. The closest I came was an old SunSpots archive that claimed the jumpers were "n/a" :-) --Chuck At 09:27 AM 3/6/99 -0500, Jerome Fine wrote:
