All you do is swap in the new ROM IC. You'll have to drill a hole in your 1541s case to attach the enable/disable switch. Probably better to put the switch in the bottom half of the shell. Yes, the drive should work fine on a VIC-20. I never had problems using my drive on both, anyway. You won't get any speed enhancement from a VIC-20 unless you burn a new KERNAL ROM for the computer to use the accellerated DOS routines! You probably already know that the command listed in Commodore literature 'U-' to set the drive for VIC-20 speed is unnecessary. The 1541 works with the VIC-20 right out of the box! 15 years of experience has shown that JiffyDOS is compatible with 99% of software and accelerates a large percentage of that! When compatibility problems DO happen, its usually with the C-64 KERNAL. To fix these issues, you occasionally have to kill the DOS wedge, or switch the C-64 back to stock KERNAL. Its available by moving the switch on the c-64 to disale JiffyDOS. I cannot recall EVER having to disable the JiffyDOS ROM in my 1541 to run a program. I've only ever done it for experimental purposes. This is because the 1541 JiffyKERNAL autodetects what version of the computer KERNAL is online. It switches to slow/compatible operation whenever the C-64 JiffyKERNAL is NOT online. --- Daniele Gratteri <daniele_gratteri@inwind.it> wrote: > Hello, > > Can you tell me how it does into a 1541 floppy disk > drive? > Can a 1541 equipped with JiffyDOS work with a VIC 20 > computer? > > Ciao! > Daniele Gratteri > (daniele_gratteri@inwind.it) > (http://utenti.tripod.it/danielegratteri) > (ICQ N° 53943994 - FIAT1100D in IRC) > > CBM & AMIGA FOREVER! > > - > This message was sent through the cbm-hackers > mailing list. > To unsubscribe: echo unsubscribe | mail cbm-hackers-request@dot.tml.hut.fi. ===== Get a FREE 6Mb webmail box from go6502! - http://www.geocities.com/profdredd As low as 2.99% Intro APR from NextCard! - http://www.nextcard.com/index6.html?ref=aff0074521 PayPal is the FAST FREE and SECURE way to send money! - https://secure.paypal.x.com/refer/pal=profdredd%40yahoo.com __________________________________________________ Do You Yahoo!?
