There are multiple types of tape images out there. Commonly the ones with 2 byte record Lengths are called “TPC” and the ones with 4 byte record lengths are called “TAP”.
There’s also a subdivision of the 4 byte record length ones into SIMH and E11. But I think it would be foolhardy to assume that all TAP’s use the .tap extension and all TPC’s use the .tpc extension. Can you try the SIMH attach options (page 8 of http://simh.trailing-edge.com/pdf/simh_doc.pdf) and see if it helps? Sometimes tape images are corrupted by moving them in ascii instead of binary mode by ftp, too.

I've got a few TPC files lying around that I've attached in SIMH and am trying to mount in RSTS. When I do this, I get the following error back from RSTS: $ mount _MM0 ?Incorrect density or uninitialized tape Looking at the TPC file itself, I'm not seeing the problem. This is how the tape starts (where ^<foo> is, of course, a single binary character): p...@vol1source D%B44310011971 [email protected] SOURCE00010001000100 8512 3 85123 000000DECRSTS/E p...@hdr2u0051200000 M 00 ^...@^@^...@^b Name .Typ Size Prot Name .Typ Size Prot DU2:[170,42] INIPFX.MAC 81 < 60> DSKDEF.MAC 101 < 60> DISKDF.MAC 31 < 60> TAPDEF.MAC 16 < 60> INIDFN.MAC 31 < 60> ODTPFX.MAC 3 < 60> SILNDX.MAC 7 < 60> INIFIP.MAC 105 < 60> INIDSK.MAC 89 < 60> INITTY.MAC 68 < 60> INIBOO.MAC 22 < 60> INIDSI.MAC 211 < 60> INILOA.MAC 26 < 60> INICOP.MAC 146 < 60> INIHAR.MAC 107 < 60> ^...@^binidef.mac 295 < 60> INIBEG.MAC 12 < 60> STACOM.MAC 9 < 60> INIBLD.MAC 4 < 60> INISTA.MAC 199 < 60> INILDI.MAC 3 < 60> FLC .MAC 6 < 60> INILDR.MAC 35 < 60> INIDST.MAC 3 < 60> INIINS.MAC 128 < 60> INIONE.MAC 193 < 60> INIREF.MAC 103 < 60> INICLN.MAC 177 < 60> INISET.MAC 71 < 60> INIIDS.MAC 19 < 60> INIMCP.MAC 4 < 60> INIODT.MAC 134 < 60> BLDBOT.MAC 16 ^...@^b < 60> INIBBR.MAC 3 < 60> ROOT .MAC 303 < 60> INIPAT.MAC 105 < 60> INIIDE.MAC 16 < 60> ASMONE.CMD 1 < 60> To me this looks like a perfectly fine bit of data. What am I doing wrong when I'm mounting it? Is this perhaps not a tape file but instead a different class of device? -- "Perhaps people don't believe this, but throughout all of the discussions of entering China our focus has really been what's best for the Chinese people.
