Configuring an EV-833 QIC controller

This is used to decide whether to read the data port or write the data port, which is 1 port address higher than the control / status port The driver hard codes STATUSREG as 0x0300, so the data reg or port would be 0x0301. Also from the driver if you output a 0x02, and then a 0x00, your drive should probably go thru a reset, which would make the head stepper buzz and seek to 0, and the tape be rewound. Page 23 of the manual Al posted on Bitsavers has the 10 location switch, which hopefully will match the one asked about earlier. Look under wangtek at 63149-001_PC-36_OEM_Manual_Dec86.pdf for the manual.. Al also posted a "30062-XXX_jumpers.pdf" which has the drive jumper settings. I would be very careful to record jumpers on the drive, as they are usually not something that has to be altered for normal operation. For this manual. The above comments for driver code are taken from the PC-36 application notes manual for the PC-36. Note that there may be oem commands that do things with your tape drive that won't match up with the manual, but the PC-36 Wangtek was used by a lot of vendors besides wangtek for their Qic drives, and can be use as good spot to start hacking.
