[comp.os.cpm] NEC 8431 DRIVE

Jhanos@cup.portal.COM (12/23/89)

Greetings, and Happy Holidays!
  
I am the proud owner of a NEC PC8401 CP/M laptop, which came with a
single 3.5" drive in the 8431 expansion drive box. The drive that is
currently installed is a TEAC FD 35-EN, SSDD drive. According to the 
books I have found, The unit is capable of being expanded to include
two drives, which would allow support of a 64k RAM, rather than the
usual 32k RAM.
  
What I am looking for, is one of the FD 35-EN drives. I have been in
contact with both TEAC (USA) and NEC (both parts and service sides) 
without success. Is there anyone out there who knows of some source
for these drives, or knows how to modify a currently available drive 
to work in the unit. I have access to numerous FD 35-F drives, which
are DSDD, but the pin connections on the back of the drives are VERY
different. Needless to say, I do not have a tech-manual for this
drive unit OR computer, and only have limited beginner's skills at
electronics repair and modification... but I'm learning!

Any help wopuld be greatly appreciated.
  
Thanks in advance...
