  1. Hello All! I recently picked up a Mac LC III curbside and it generally works great, and is running OS 7.1. I cleaned up the case and blew a bunch of duster inside (including floppy) to ensure it would work as well as possible. The machine itself works great, but when I try to put in a floppy, it will ALWAYS ask me to format it. It sounds like I remember they are supposed to sound, and it ejects the disk properly. It will attempt to format but then after the second check say "initialization failed" and eject the disc. I am wondering if: -Its bad discs (only have one pack of mac disks right now, others up at my parents need to go grab) -Its a bad drive (not repairiable, needs to be replaced) -The drive needs to be properly cleaned with a cleaning kit, internal dirt/grime on the read mechanism is whats the issue Additional information: -I tried yet to be formatted one sided discs from my Atari ST and those also wouldn't format -The discs I was using would read and format on my G3 Pismo, but then would crash the computer when I tried to eject them and then become corrupted. What is your take and what should I do FIRST? Thanks in advance!! Worst case scenario I do have an external 3.5 drive that I use with my IIgs I could always try..
  2. For this CoCo2 I am selling, I found several 3.5" floppy drives which will work with the FD-501 interface. I understand RSDOS only uses these disks as SSDD for 160k of storage and to use the WD1773 controller to its fullest you would need OS9. It looks like there are some 80 track modifications available which would allow for 720k 3.5" drives. All that considered, is there a lot of call in the CoCo world for 3.5" drives? If so then I should go ahead and mount one in this FD-501 case.
  3. So, I have a bunch of Atari stuff for sale. I'm not sure as to what to price it (I'm not an Atari guy, I'm a Nintendo guy), and I'd like it to go to a Atari collector or someone who will put it to use/appreciate it. I'm not looking to make a killing. I just want a fair/going price for the stuff. It all works. The list consists of: Atari 520ST - Good shape - powers on/runs Atari 1040ST - Good shape - powers on/runs Atari 520ST - poor shape - powers on/runs 3.5 SF354 Atari 850 Atari 810 - 5.25 XM 301 410 Cassette Monitor SC1224 It's a rough list. I imagine most of you on here will know more about what I have. I have photos. Some of them are doubles. I want to make sure you can see the condition of the items. https://imgur.com/a/doqNz
  4. SOLD! $35 Shipped 1 Fellows and 1 Memorex 3.5" disk file box. Both boxes still have their plastic dividers and are if good but used condition. Includes 60+ used discs in various conditions but all were readable when I checked their contents. Some have been erased. Some only had data written to them once and some were used multiple times. Bonus: I've included about 30 brand new disk labels as well.
  5. After putting together a couple of Dropcheck's XF551 boards, I decided to see if I could make use of the old PCBs and with a little cutting I was able to fit a XF551 pcb and a 3.5 mechanism into a 1050XL case. The back of the case had to have a large rectangular cut out and that is the only bad cosmetic issue. I would like to use the 1050 power switch and power on LED. I have several non-working 1050s so I think I can cut off the pcb section that has the switch and LED; that leaves wiring the front switch as my only real challenge. I would like to know if I could leave the 551 switch in place in the off position and run wires from the power jack through the 1050 switch to the back of the 551 switch.
  6. Enter the Flash ROM 99, since it's introduction, it's stirred things up with the ability to hold so many programs and load them so much faster than from a diskette. We've been able to save a lot of disk space. With this savings in mind, have you given any consideration to how we can maximize that extra disk space, or create new environments or expand programs in ways never considered before? For you FR99 users, how have your TI habits changed since you started using it? With or without the FR99, has this device inspired any new ideas or ways to exploit the TI? What have you done, if anything with all the extra space? Any other comments?
  7. Last night I went through a torrent of hardware swapping and hours of troubleshooting. I recently picked up a Sony MP-F11W-2Z 720k floppy drive with the intention to use it either in my TI* or as a replacement mechanism in my Commodore 1581. But I ran into a problem. Connected to a CoCo2 the drive works perfectly fine: it will format a disk and use it. However, when connected to the BwG the drive will format but fails verifying sectors starting at 720, which is at roughly 180k of a 360k format. I connected a Panasonic JU-257 (1.44MB drive) and get the same results with the BwG. Other drives produce the same results. As expected, the drive head does not traverse the entire disk surface. FWIW, the BwG and the CoCo's FD-501 both use the WD1773. I may be over-thinking it but my first thought was "precompensation." Seems a bit of a stretch. Can anyone steer me in the right direction here? * Understanding, of course, only 360k of the disk will be usable.
