Thanks for the replies. I decided to phone the Micropolis BBS as
suggested since it was the weekend. Here is an excerpt from the file
where I found the information which I used. I don't know why ncyl=1890
in the table whereas the entry supplied by Parity to Steinar Haug has
ncyl=1887 .

---Excerpt follows:
The following table represents the parameters to be entered into
the format.dat file on SUN workstations for the newest Micropolis
drives.

Parameter 1528 1548 1624 1908
CTRL MD21 MD21 MD21 MD21
NCYL 2102 1701 1647 1890
ACYL 3 3 3 3
PCYL 2100 2112 2112 2112
NHEAD 15 15 7 15
NSECT 83 131 114 95
RPM 3600 3600 3600 5400
BPT 42496 79218 67900 56241
TRKS_ZONE 15 15 7 15
FMT_TIME 5 6 4 5
ATRKS 45 45 21 45
ASECT 8 8 4 8
---End of excerpt.

Here are the replies that I received which helped answer my request.
Also, thanks to bb who sent me a big list for other drives. You can
add this to the list.

disk_type = "Micropolis 1908-15" \ : ctlr = MD21 : fmt_time = 4 \ : cache = 0x14 : trks_zone = 15 : asect = 8 : atrks = 45 \ : ncyl = 1887 : acyl = 3 : pcyl = 2112: nhead = 15 : nsect = 95 \ : rpm = 5400 : bpt = 48640
