by 16 bits.
Local ROM
The CTC card firmware is in 16K bytes of ROM configured as 8K by 16 bits.
Cartridge Tape/Floppy Disk Interface
The Cartridge Tape/Floppy Disk Interface is a WO 2793 Floppy Disk Controller. The chip contains
write precompensation and data separation circuits. The 34-pin data and control connector is a SA-450
interface.
CM 195H Equipped Device Table Data
The following table shows the Equipped Device Table (EDT) data for a CTC card. A value of 0
means NO; a value of 1 means YES. The indirect device (indir_dev) is only applicable to systems
equipped with Small Computer System Interface (SCSI). The request queue size (rq_size) and the
completion queue size (cq_size) are CTC software defined values. As such, the rq_size and cq_size
values may differ between versions of CTC software.
