- WARNING... This is a long rebuttal to read, you may want to 'skip' now.
-
-
- I regret to have to resort to writing a rebuttal to a rebuttal but Rick
- Horwitz
- (a biased employee of Texel) has forced me to by actually resorting to a
- series
- name calling (unprofessional in its own right) and a style of writing that
- implies that I do not know what I am talking about when it seems that I may
- know more about this Texel than even He, an employee knows.
-
-
- Fact 1 (relating to multisession not shipping with firm date)
- ==== For this matter Rick Horwitz seems to issue a coverup when I called Texel
- myself just a day before and that is what prompted me to write:
- >Reason #1, the Texel is NOT CURRENTLY multisession
- compatible and no firm
- >date was given to me by their sales dept. when it would be.
- (As of yesterday)
-
-
- He could have just agreed and cited his guess as to when it will ship. I was
- not spreading any mistatements, it was the truth.
-
-
- Fact 2 (Relating to the lack of two distinct led indicators) Again I spoke the
- truth. Of course I knew it was a tri-state led, as most are, but I do not
- like tri-state leds. That is why I wrote :
-
- >The Texel does not have a separate set of LEDs as the Toshiba
- >3401 does for activity and "on", it shares one indicator, I recall.
-
-
-
- Fact 3 (relating to inability to adjust volume via SCSI commands as all other
- existing SCSI-2 devices do) He concedes that I am right about this but I have
- never heard of a multimedia card on a Mac in my life and doubt that one would
- ever be a common device. Perhaps this Texel mechanism was crippled just for
- use on IBM compatibles. Again I was 100% correct and not being misleading.
-
-
- Fact 4 (relating to inability to set audio play modes as all other existing
- devices claiming SCSI-2 compatibility (Sony, Toshiba) can do. WOW! I actually
- investigated this calim of mine and discovered a horriying truth to it! I was
- using the mode select page 14 correctly (same code used on other SCSI-2
- devices without modification) and discovered that the right audio source could
- not be connected to either the right or the left speaker FROM THE HEADPHONE
- JACK. I did not spend the time to try the Phono plugs, but an expensive test
- audio CD confirmed that the Texel 3024 did not play stereo from the headphone
- but instead was playing left audio out both speakers. I will investigate a
- tiny tiny bit more in the future but not for a couple weeks. I am
- convinced I
- am correct and history may prove me right.
-
-
- Fact 5 (Relating to improper implementation of SCSI PREVENT/ALLOW MEDIUM
- removal. No disagreement here between us, but am amused to learn about the
- padlock feature for those with expensive CDs in a library setting.
-
-
-
- Fact 6 (related to the following stement I made) :
-
- >Reason #6, The Texel does not support the "PLAY (12)"
- command. All other
- >SCSI-2 compatible CD-ROMs I know of support this very very
- useful command.
- >In fact, its lack makes it very very difficult for a novice
- to try and
- >play more than a few minutes of contiguous sound from the
- center of a large
- >classical music symphony movement (< 15 minutes or so?)
- using block
- >addresses. It mercifully does have the other limited version
- called "PLAY
- >(10)" but the SCSI-2 specification clearly states underneath
- the table
- >enumerated as "13-3" for CD-ROM.....
- >.... If any of the commands indicated by an * in the TYPE
- column are
- >implemented, THE PLAY AUDIO commands shall be
- implemented. ......
-
- That statement is 100% correct as I worte it. Oddly, Rick Horwitz, does not
- directly address this issue but instead talks about a vendor unique audio
- command and a command that has nothing to do with the block addressing
- PLAY AUDIO command. Sure, one could write algorithms to work around the
- deficiency of a missing PLAY AUDIO (12) SCSI-2 command but why botther.
- The math is not trivial. The block address needs to be converted into
- minutes, seconds, and frames (75ths of a second) and added to a 150 fram
- offset. And there may not be a solid correleation between the two addressing
- schemes. SCSI-2 I think is unclear about how to convert when the logical
- block size is not set to 2048 but instead is set to 512 requiring further
- multiplication or division before poroceding. If you just read my statement
- at face value you will see that it is correct and definitely not misleading.
- I find it odd that he points a finger at Sony (Whose SCSI-2 compliant
- device does provide the valuable PLAY AUDIO (12) command (only 95% certain).
-
-
-
- Fact 7 (regarding lack of SCSI EJECT command) I think it is quite distressing
- that my fine reputation is smeared with such allegations that I am misleading
- people by saying the following simple phrase:
- >The SCSI EJECT command is not implemented in
- >the device. This is present on all other devices I know off that
- >claim full SCSI-2 compliance.
-
- I know of only two other devices besides the Texel that Claim to be fully
- SCSI-2 compliant and those devices are the Sony-8003 and the Toshiba
- 3301 and Toshiba 3401. THESE DEVICES DO INDEED provide the eject command
- but obviously I am not implying that the SCSI-2 specification claims that
- supporting the SCSI EJECT command is a "MANDATORY" option. Of course not.
- If it was a mandatory option I would have mentioned it. After all, I
- am not a misleading type of person and do not try to put words in others
- mouths that they did not type explicitly.
-
-
- Fact 8 (regarding lack of insertion motor) No disagreements on this issue.
-
-
- In summary. I like a legitimate flame war as much as the next Usenetter,
- but I regard myself as an unbiased and non-misleading person and only
- write from my personal experiences on any matter I discuss. I find the
- sentence he wrote :
-
- > However, making unwarranted claims that are simply false or
- > impartial will not be tolerated.
-
- Totlerated? Tolerate what? The simple honest truth presented without any
- misleading or false statements??
-
- That is incredible to believe!!! Its almost (but not quite) enough of a
- reason for me to spend hours of time picking apart Texels latest offerings
- to try and find even more significant shortcommings than the ones I listed
- so far.
-
- I am sorry for this longwinded rebuttal to a rebuttal but folks who know
- CD-ROM technology and SCSI commands will undoubtably understand my viewpoint.
