I, too have a C128D. I have tried using FH version 6.0 with it but it would not work; that is until I switched the 1571compat. internal to the C128D to drive #9 and then used a 1571 drive as drive 8. It works fine now. I also have had problems with using many word processors, like Geos, when the 1571 compat. was drive 8 and the computer does not play digitized sound well . For example the game Cave of the Word Wizard a childrens spelling game requires the Wizard in the game to say the word aloud and have the child respond with the correct spelling; unfortunately one has to turn the voluem of the Monitor/T.V.(have tried it with both) up to maximum to hear him whisper. I tried the same game with a C128(old version) and the game works perfectly as do SID tunes like the theme from Skate or Die(digitized sound). Any others have the same problems? I have had the system checked and it is in perfect shape, design flaws.

A long time ago, a friend was working on a speech digitizing and recreation program that relied on the SID to provide a pop when needed to generate the sounds (I believe this was accomplished via the volume register). Similar to the pop you hear when you put the SID volume from 0 to 15 suddenly... In any case, I do also recall that he had some problems when he ran into a newer version of the SID which had the popping problem greatly reduced.... his program became quite mute. That's what you get for relying on sneaky techniques and hardware bugs. I'd be willing to bet that the Word Wizard game also relies on this or some other similar SID bug to provide it's speech capability. Very bad programming practice. There's nothing wrong with your C128D, if this is the case. There's something wrong with the program! :-| (Gee, how many times have I gotten on a soapbox about compatibility?) -- jgreco@csd4.csd.uwm.edu Joe Greco at FidoNet 1:154/200 USnail: 9905 W Montana Ave PunterNet Node 30 or 31 West Allis, WI 53227-3329 "These aren't anybody's opinions."

That's what you get for relying on sneaky >techniques and hardware bugs. You're right, Joe. I talked with one of the test engineers for the 6582/ 8580 SID chip, which is the new 9 VDC version used in 64Cs and 128Ds. He said that a lot of work had been done to clean up the filtering, and as a result, the behavior is quite different from the 6581 SID. You have to use radically different capacitor values for the 6582/8580 as well. I have noticed poor sound from digitized samples when played on the 6582/8580 too.

Help!!! I own a C128D and want to install a device change swith on it like my 1541 Drive has. Where are the jumper blocks???? I Can't seem to find them. Thanks

I Can't seem to find them. If you're facing the front of the machine, they should be in the left front corner, about 3 inches back, 2 inches from the left. They strongly resemble the jumpers on the old 1541; the semi-circles connected by tiny solder bridges.

Last I looked the jumper blocks were near the center of the board, about 1 inch east of the power supply and floppy drive headers (next to the 6522 at U106). Cut the front one for U9, the back one for U10, both for U11. If you are going to install a switch, place it between the side of the jumper pad nearest the 6522 and ground. -- Fred Bowen uucp: {uunet|rutgers|pyramid}!cbmvax!fred domain: fred@cbmvax.commodore.com tele: 215 431-9100 Commodore Electronics, Ltd., 1200 Wilson Drive, West Chester, PA, 19380
