But the sticker is hardly a reliable test. A better test is to look look
at the part numbers of the P5 PROM (the lower left chip on the card) and the P6
PROM (left column, second from the top).
13-sector 16-sector
--------- ---------
P5 341-0009-xx 341-0027-xx
P6 341-0010-xx 341-0028-xx
The 16-sector PROMs may also be labelled "P5A" and "P6A".
A program can test the card type by looking at its slot ROM space. The
signature bytes are as follows:
$Cn01: 20
$Cn03: 00
$Cn05: 03
$Cn07: 3C
$CnFF: FF if 13-sector; 00 if 16-sector

018- Can a Disk ][ Drive be used on a IIc or GS
smartport?
Yes. Call Jameco Electronics. Get the S20-pin header- to -DB19-pin
connector module. It is intended for adapting II/II+ drives for IIc. (Part#
