#External Drives
2 messages in this thread
I've picked up an external drive from a company called Halted Specialties. The
drive itself is the same drive used in the amiga but the company didn't have
any documentation on the drive. Can anyone tell me what the pinouts are for
the 34 pin connector on the back of the drive and what lines should be kept for
the 23 pin connector on the back of the Amiga, Thanks… John 73647,1534
John,
I'll give you the pinouts….but I think there is a matter of an
interface board also.
34 pin connector:
1. GND 18 DIRB
2. CHNG* 19 GND
3. GND 20 STEPB*
4. MTROD*(LED) 21 GND
5. GND 22 DKWDB*
6. N.C. 23 GND
7. GND 24 DKWEB*
8. INDEX* 25 GND
9. GND 26 TKO*
10.SELOB* 27 GND
11.GND 28 WPRO*
12.N.C. 29 GND
13.GND 30 DKRD*
14.N.C. 31 GND
15.GND 32 SIDEB*
16.MTROD* 33 GND
17.GND 34 RDY*
There is also a 4 pin SIP header that has pinouts:
1=+12v, 2=gnd, 3=gnd, 4=+5v
The Amiga db23 disk port pinouts are:
1. RDY* 13 SIDEB*
2. DKRD* 14 WPRO*
3. GND 15 TKO*
4. GND 16 DKWEB*
5. GND 17 DKWDB*
6. GND 18 STEPB*
7. GND 19 DIRB
8. MTRXD* 20 SEL3B*
9. SEL2B* 21 SEL1B*
10.DRESB* 22 INDEX*
11.CHNG* 23 +12v
12.+5v
I'll leave it up to you to figure out what to do with them.
