Lord Crass, there are two types of 1541-2's its easy to tell the difference from the front, the direct drive model has a thicker lever on the front from front to back, and is recessed in the moulding, and does not have any adjustment for speed control. The belt drive model has a thinner lever that is not recessed into the front bezel, is a newtronics mech, and has the speed control on the top of the mech, just like a lever 1541 drive does.
I also have a 1571 that has been modified to control the speed of the direct drive motor. It involves soldering two wires to a potentiometer, and a switch to un-connect it. I sent all of this to womo. send me a email and I will dig out all the pictures I sent him about it, I havent tried to see if it can be retro'd into a direct drive 41-2. A lot of the traces are under the magnet spindle assembly on the bottom and you cannot see much, I might pull it apart and hopefully not damage the spindle assembly and see if I can tac some small wire onto some points and do some testing. (Would be nice to finally come up with a solution for these drives since Software Support never did, or neither Did Free Spirit
Been playing around with a enhancer 2000 drive, strange I have two flavors a brown and a white one, the brown one has a copy of 2.6 CBM does, but still is not very compatible, and the white one has Enhancer 2000 v2.0 dos, same thing, but the brown one has almost the same dos as whats in a Excelerator plus drive, there is only 8 byte difference, but the Excelerator dos wont work in the Enhancer even after building a adapter to switch dataline D3 and D4 to decode it correctly, it just flashes its led light, I have a valid dump of the Excelerator dos, so I put a 1541-2 rom into the Enhancer 2000 and now it loads Defender of the Crown finally, and seems to work on all the other V-max and Vorpal ramboard copier needed based games. And I dumped the Jiffydos for the first time for the Excelerator plus FSD-2 and not getting garbage. The brown one has a bad 2k sram, gets hot hot hot!, so I am going to socket it, and put a different sram chip and see if that fixes it tonite.

Strange, the 2ksram did indeed fix the Enhancer 2000 drive, it loads almost everything now with 1541-2 dos in it, but strangly it has a problem with Defender of the Crown!, just like Pete had problems getting a good image, when the drive is cold and been turned off for a while it seems to load the original, I can see it just past 18 and do a sync check, that always passes, then the head moves fast toward track 1, well it doesnt seem to always make it to the track it needs, and just sits there, sometimes it moves the head more and some times less, but it always goes to the sync track ,then moves toward track one, strange though,, I did the maverick copy, mine are all V1 DOTC's and even the patched copies do the same, but strangly sometimes it loads all the way up, but usually only when the drive is cold, So I tried freeze spray, and that doesnt change a thing. Put it in a real 1541-2 drive, and it always loads up. The Enhancer 2000 seems to be much much more compatible, it loads Renegade, Alcon, Arkanoid 1+2 3stooges rocket ranger, and almost every EA title (which is the ones it really hated the most) It seems to be fine with Rapid-lok stuff just fine, even with its own dos.
Must be a timing problem, But I guess I was wondering Pete if the Maverick copier is actually reading something from that sync track, usually a patching parameter does not need to read anything from a original to patch a copy, and there are two variants in Maverick V1 and V2 Defender of the crown parameters. Seems to jump to the sync track and read something there, and then write that along with byte patches. And then on side two seems it patchs bytes again. strange, did they do a nibble check on side two at some point ???
I also used the DOTC paramater on Supercard 5.0 , non PLUS version. And it even needs the original disk.
