I posted this once, and supposedly got an answer back, but I was on vacation, so I missed it. Could either the original answerer or somebody who saved the answer please get it to me? Thanks. A TK70 cartridge tape drive is not supported under RSTS for my micro-PDP-11/73. I am told it will work, and that many people are using it, but that DEC would have to try it out on every possible configuration before they could say that they are supporting it, and that they are not about to do that. With that in mind, if you are using a TK-70 under RSTS on a PDP-11, could you please get back to me, either here or at my address? Thanks. earl smith earl@cs.columbia.edu (212)854-8884

Hi, (check your Reply-To: field, my E-mail relpy to you bounced) In article <6483@columbia.edu> you write: >I posted this once, and supposedly got an answer back, but I was on vacation, >so I missed it.

I seem to be that original answerer :-) >A TK70 cartridge tape drive is not supported under RSTS for my micro-PDP-11/73. >I am told it will work, and that many people are using it, but that DEC would >have to try it out on every possible configuration before they could say that >they are supporting it, and that they are not about to do that.

We don't have any software problem running a TK70 here under RSTS9.4. I'm not sure about the difference between micro-PDP-11/73 and PDP-11/73plus but I think both are QBus J11s. So there shouldn't be any problem. I'm using the TK70 for {off|on}line backups. No tricks, but you should have a 22bit box for online operation. Just add the TU: driver (the TMSCP support ? prompt, I think) to your monitor at SYSGEN and install a non-standard CSR address with INIT.SYS, if any. I think that the rumors about that RSTS does not support TK70 base on the fact that INIT.SYS sometimes works goofy with many devices at the floating address region 7760??? (I have had this problem with additional MSCP control- lers and a DZV:). As the symptom, INIT.SYS doesn't detect all hardware mounted on the QBus using this adresses. The fix is (on my experience) to tell INIT all standard addresses of the non-detected controllers explicitely as non-standard CSR addresses and reboot. This should work. If this does not help, you perhaps didn't select the correct slot for the controller. (There mustn't be a free slot between CPU and a (T)MSCP controller ! The drive wouldn't interrupt correctely.) BTW, TK70 has hardware reliability problems. They are dependent on the working temperature. If blacking out, the tape rewinds. This is fatal because the monitor seems not to recognize this correctly. The system won't crash but you can get a non-recoverable '?Device hung or write locked' then. If you want to use the TK70 again you must reboot :-( Hope this helps. -thomas -- Thomas Cervera | UUCP: alderaan@tubopal.UUCP SysMan RKOpdp (RSTS/E) | ...!unido!tub!opal!alderaan (Europe) D-1000 Berlin 30 | ...!pyramid!tub!opal!alderaan (World) Motzstrasze 14 | BITNET: alderaan%tubopal@DB0TUI11.BITNET (saves $$$)
