Got it. Thanks. So, 3-5/8" is actual. I was being too picky about your 3" statement :-) It seems to be well known that the number of each size you get in the SF-7000 package is, umm, random... so a guy needs to get several packages and hope for plenty of white ones. Thanks again, Chris -- Chris Elmquist

Hmm. 3" plastiband seem to be rare or my Google-foo is pretty bad. Do you have a source for these? I have found only 2-1/8", 4-1/4" and 6" so far. Tack. -- Chris Elmquist

Rik Bos told me that the best way is to heat the old band slightly. I used a SMD desoldering air gun which I set to 100 degrees centigrade and then blowed heat air onto the tape from some distance until it changed from a white matte surface into a darker brown surface. Then it easily came of the tape without damaging the tape. There were some kind of residue left which I used isopropyl alcohol to remove. I also added some lubricant to the tape rollers. This far I have recovered ten tapes successfully. Two tapes only read 128 blocks. I used RT11 to recover the tapes but it seems that the /IGNORE option doesn't skip bad blocks at all. I had the hope that COPY/DEV/FILE/IGMORE DD0: TU58.DSK would skip the bad blocks. But I might be misunderstanding the syntax? I will try to use DUP directly and see if that makes any difference. Something like * TU58.DSK/F=DD0:/I/J But according to the manual it just skip the bad block which is annoying since then all remaining blocks is shifted block number wise. Probably have to manually recreate the structure using dd? /Mattis > > -Original Message- > From: cctalk [mailto:cctalk-boun...@classiccmp.org] On Behalf Of Mattis > Lind via cctalk > Sent: Wednesday, August 22, 2018 2:50 AM > To: General Discussion: On-Topic and Off-Topic Posts; Al Kossow > Subject: Dilog DQ604 RL01 / RL02 emulation on ST506/ST412 disk. > > I unearthed some old TU58 tapes that luckily was readable (after carefully > replacing the tension band) > > - > >

Which length band did you find worked best as a replacement? -Original Message- From: cctalk [mailto:cctalk-boun...@classiccmp.org] On Behalf Of Mattis Lind via cctalk Sent: Wednesday, August 22, 2018 2:50 AM To: General Discussion: On-Topic and Off-Topic Posts; Al Kossow Subject: Dilog DQ604 RL01 / RL02 emulation on ST506/ST412 disk.

Dilog DQ604 RL01 / RL02 emulation on ST506/ST412 disk.
I unearthed some old TU58 tapes that luckily was readable (after carefully replacing the tension band) It resulted in two RT11 V4 images with two versions of the formatter program. One is bootable and the other not. http://storage.datormuseum.se/u/96935524/Datormusuem/Dilog/DQ604/sq604c.dsk http://storage.datormuseum.se/u/96935524/Datormusuem/Dilog/DQ604/sq604d.dsk I tried to run the formatter program in Simh: .run sq604C.sav TEST AND FORMAT DQ604 DISK SYSTEM (REV C.) DRIVE FORMATS AS RL01 UNIT (5.24 MB) SWITCH 3 CLOSED ENABLES BOOTSTRAP THERE ARE 17 PHYSICAL SECTORS PER TRACK (2) ALTERNATE CYLINDERS MAY BE ASSIGNED PER UNIT THE INTERLACE FACTORS ARE TWO OR THREE TO ONE DATA BUFFER ERROR USE PROCEED (P) TO REPEAT TEST HALT instruction, PC: 006312 (BR 6202) .RUN SQ604D TEST AND FORMAT DQ604 DISK SYSTEM (REV C.) DRIVE FORMATS AS RL02 UNIT (10.48 MB) SWITCH 3 CLOSED ENABLES BOOTSTRAP THERE ARE 17 PHYSICAL SECTORS PER TRACK (4) ALTERNATE CYLINDERS MAY BE ASSIGNED PER UNIT THE INTERLACE FACTORS ARE TWO OR THREE TO ONE DATA BUFFER ERROR USE PROCEED (P) TO REPEAT TEST HALT instruction, PC: 006312 (BR 6202) So it appears to be runnable. I also found the manual for the board and scanned it: http://storage.datormuseum.se/u/96935524/Datormusuem/Dilog/DQ604/DQ604.pdf Now the next step is to see if this can make the DQ604 board I have working with David Gessweins MFM emulator.
