From a fellow who does not have access to comp.os.vms. If there is a VAX hardware FAQ somewhere, this ought be included. Bill mooney@umiami.ir.miami.edu ------------------- text of forwarded message follows ----------------- From: monscheuer%tst-hh.uucp@Germany.EU.net Subj: TQK70 JUMPERS I don't know weather you've already got an answer to your TQK70 request on the Internet or not. If so, here is another one: -------------------------------- | | | | Q-bus side | Unit select | | ::::::: | | | |-- :::::::: | Jumpers A2 - A12 are used for to | | A12 A2 | CSR-address selection. drive| | | The other jumpers only define the |-- | unit number (i.e. MUB2 instead of MUB0) -------------------------------- A12 11 10 9 8 7 6 5 4 3 2 1 1 0 0 1 0 1 0 0 0 0 = 774500 0 0 0 0 1 0 0 0 0 0 1 = 760404 You've got the rule ? The first digit always is seven and cannot be altered. The second digit is either seven or six. If A12 is in, it means seven, otherwise it's six. A11 - A9 determines the third digit. ( 100 binary = 4) A8 - A6 determines the fourth digit. ( 101 binary = 5) A5 - A3 " " fifth " ( 000 0) A2 determines the last digit which is only valid if it's 0 or 4(oct). IF A2 is in, it means 4, otherwise it's 0. A definition for the interrupt vector isn't needed, as it is always the lowest according to the devices standard or alternate address. CAUTION : Don't forget to adjust the other devices on the Q-bus !!! :-) For example : Configuration before TK70 application Device: UDA Name: PUA CSR: 772150 Vector: 154 Support: yes Device: TU81 Name: PTA CSR: 774500 Vector: 260 Support: yes Device: QNA Name: XQA CSR: 774440 Vector: 120 Support: yes Device: DHV11 Name: TXA CSR: 760440* Vector: 300* Support: yes Device: DHV11 Name: TXB CSR: 760460* Vector: 310* Support: yes Configuration after TK70 application Device: UDA Name: PUA CSR: 772150 Vector: 154 Support: yes Device: TU81 Name: PTA CSR: 774500 Vector: 260 Support: yes Device: QNA Name: XQA CSR: 774440 Vector: 120 Support: yes Device: TU81 Name: PTB CSR: 760404* Vector: 300* Support: yes Device: DHV11 Name: TXA CSR: 760440* Vector: 310* Support: yes Device: DHV11 Name: TXB CSR: 760460* Vector: 320* Support: yes Note that the DHV11 vectors have to be adjusted !!!! If this is not done, the DHV11s will be in a muddle and the tape drive will remain invisible. Depending on your configuration other devices may be affected. BTW, have you ever tried to power up the drive without a connection to the controller ? If the "tape in use"-light is still on under this condition, the drive may be defective. :-( Hope, this was useful... I would be pleased, if you drop me a line about it - if you do so, please DON'T use any kind of REPLY. Use one of the addresses below.
