20 Jan 1997 - Two new sections: News about DayStar and Turbo 601 Reviews added. Bronson has sent in a link to a benchmarks page that he has contributed to.
Take a look at at some benchmarks for the Turbo 601/100 (thanks David Engstrom).
We are going to try a compile a database of benchmark results from different Turbo 601 systems, to see how different NuBus boards effect performance, etc. As well as others we have talked to, we are interested to see results from a Turbo 601 with a SCSI-2 accelerator. If you want to contribute results, please send either Mac Bench 3.0 or 4.0, or Speedometer 4.0 files in a Stuffit archive (.sit) to Willi Murray.
Update (20 Jan)
Bronson has contributed benchmark results to the Speedo page, his machine is listed as the IIci/66.
Visit a page with lots of information about clock-chipping the Turbo 601/66. This looks a bit more complicated than clock-chipping normal PowerMacs, but apparently the Turbo 601/66 can be popped up to 90MHz without a problem.
120 MHz Turbo 601? One reader informed us that after taking the heat sinks off of 4 Turbo 601/100 boards, she discovered that two of the processors are labelled 120MHz rather than just 100MHz. This could mean, potentially, that the 120MHz boards could be clocked up to run at their full speed. It is very doubtful, however, that this would actually work in practice due to limitations in the hardware of the original computer. There would, in all probability, be overheating problems due to the increased clock speed. If anyone has any further info, please send us a note.
Sadly, in March and April 1996 DayStar had to lay-off a number of staff. The following articles also outline the rational behind DayStar's shift from accelerators to multi-processor machines and upgrades.

There is a trick in the Turbo 601 control panel that lets you get information about your board. Hold down Command-Control, and click on the Turbo 601 logo. Among other things, Bronson Trevor's Turbo 601 returned the following:
ROM Family: $77D
ROM Checksum: $7C4F0317
ROM Version: 2.5f2
Patch ROM Version: 1.1
Willi Murray gets these same numbers from his recently purchased Turbo 601. Bronson reckons that these are the most recent versions that a board could have. This brings us to an interesting note, however, and that is that the Turbo 601 contains a Patch ROM. Like good modems it is possible to upgrade the board using a piece of software. The first time a user boots up with v1.1 of the Turbo 601 control panel installed, for example, it will do just that.
Update (19 Jan 1997)
Jubel Chen has had his Turbo 601 modified to fix the 256 colours problem and his board now returns the following data:
ROM Family: $770
ROM Checksum: $7B34B470
ROM Version: 2.5f2
Patch ROM Version: 1.2d4
