I have seen several Apple // systems running with transwarp. I'm envious. In fact, It seemed to me that disk IO speed was even increased dramatically. The problem is that there is no way to put any "known" accelerator in a //C. That's why so many of us got excited over the ZIPCHIP. I do believe that it would be possible to butcher a //C, removing several key parts and making room to wire up some sort of Dr. Lizardo accelerator. This would not be practical but it would be a great way to sell non-existent accelerators to us poor //C lovers. Did anyone notice that ZipChip has been upgraded? Nothing so blatant as a claim, of course, but a new design on the chip in the ad and it is now the 4-C version.

Increase in disk IO speed was an illusion. The disk controllers want 1Mhz. One sets the appropriate dip switches such that those slots get 1 Mhz. ****DISCLAMER: My comments, etc., are my own shakey opinions ******** | Bruce P.

Yes, the floppy drives still run at 1 mhz, but access does speed up a smidgen, since the cpu can handle ingoing and outgoing data faster. The Transwarp really shines when used with a hard disk though, since (at least for the Sider) the hard disk controller card can run at full Transwarp speed. Another effect is a seemingly faster screen. This, however, is really an illusion, and just reflects the new speeded up output rate of the cpu. On another Transwarp topic, has anyone run into problems using the Transwarp with telecommunications programs, specifically using interrupts? My Transwarp works great with everything else, but when I attempt to use it in conjunction with a telecommunications programmers package called Modemworks, the Transwarp always locks up within a few moments of initializing the super serial card and modem. I've spoken with the programmer and Applied Engineering, and neither has had problems of this nature. In fact, the programmer uses a Transwarp with Modemworks all the time. The lockup consists of the computer freezing up, then rebooting itself with the with the Transwarp disengaged after I press ctrl-reset. Ideas anyone? Other than this difficulty, the Transwarp is an excellent card. The Zip Chip looks great too, but vaporware usually evaporates before it can be put in a computer! Seriously though, any news from Zip Technologies, the Better Business Bureau, or the U.S. Postal Service? Michael Yellin Carnegie Mellon University BITNET: Sparks@Drycas ARPA: MY0l@Andrew.cmu.edu

Yes, has anyone heard anything substantial from ZIP Technologies? I've been
calling them a lot, but they keep maintaining that they're "just as frustrated
as the customers," because THEIR manufacturers haven't shipped the chips to
THEM yet. They say that the chips should be available definitely before the
end of January. They'd better!
To insure my reception of any replies, please respond via e-mail. Thanks!
