3.5" MFM hard disk

29 May 2001

...
  	The Kalok is
615 cylinders and 4 heads.  It's currently
  connected to a converter board, similar to the ones that Adaptec
  used to make for connecting MFM drives up to various other interfaces. 
Yeah? Which make/model?  If it *were* Adaptec, I'd bet it's an ACB-4000,
in which case it's MFM<->SCSI (sortof).  What sort of machine is it
going into? 
	As stated before, the board was made by Sun Remarketing and 
it's their part# 00-002 and has the following major chips on it:

	- SCN8031HCCN40
	- UM6116-3
	- SMS OMTI 20513B
	- SMS OMTI 20507
	- Sun Remarketing ROM 341-8005

	There are also various resistors and surface mount chips 
(74LS374B1, 74LS373N, 74LS280B1, 74LS08N, 74LS14N, MC3487P, MC3486P). 
There's a 26pin header input from the parallel output of the Lisa as 
well as a power input.  There are then the standard MFM dual cable 
outputs to the hard disk as well as a power connector going to the 
hard disk.
