The disk controllers want 1Mhz. > One sets the appropriate dip switches such that those slots get 1 Mhz. 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
