I have a Taiwanese "turbo XT clone". It currently uses an Intel 8088-2 as the processor, and the clock speed can be switched at will between 4.77 and 8 MHz. I have ordered a NEC V-20 processor chip (8 MHz version), which I plan to install in place of the 8088-2. My question is: Once I install the 8 MHz V-20, is there any reason I would ever want to run the clock at the slow speed (4.77 MHz)? Or should I simply run at 8 MHz all the time, no matter what software I am running? In asking this question, I am not worrying about timing-dependent pro- grams such as games. I realize the timing on these will be all messed up once I switch from an 8088 to a V-20; I don't care. -- Rich Wales // UCLA Computer Science Department // +1 213-825-5683 3531 Boelter Hall // Los Angeles, California 90024-1600 // USA wales@CS.UCLA.EDU ...!(ucbvax,rutgers)!ucla-cs!wales "Sir, there is a multilegged creature crawling on your shoulder."

On my Tawainese Turbo Clone (with an 8MHZ 8088), when I operate at 8mhz with either Qmodem or Procomm, I get missing characters when I communicate (at 1200 baud). Otherwise, the comm port functions just fine at 4.77 MHZ. I don't know if this problem is unique to me or not. Perhaps if some people replied to me via the mailer I can decide whether to have my motherboard serviced or not....... -- Dennis Lou {ihnp4 sdcsvax} jack!wolf!dennis
