90.0. "cheap generic floppies drives?" by FREKE::LEIGH () Thu May 12 1988 20:53

    I am looking to add a second floppy to my ST and would like to do
    it cheaply.  Are their any stores in the Nashua NH area that sell
    generic DSDD 3.5 in floppies (for IBM etc.) at a reasonable price?
    
    And where can one get the cable to use generic IBM drives on the
    Atari or what is the pinout so that I can make my own cable.
    
    thanks
    
    Chad

90.1	Pinout for which?	MILRAT::WALLACE		`Thu May 12 1988 21:19`	3
	Do you need the pinout for the ST or for the IBM drive? Ray
90.2	both pinouts actually...	FREKE::LEIGH		`Fri May 13 1988 15:42`	19
	RE: -.1 I would need the pinouts for both actually so I would know what to attach to what pinwise. A simple ST IBM --------------- 3 6 7 10 etc. would do (above example represents nothing). thanks chad
90.3	ST floppy pin out	MILRAT::WALLACE		`Mon May 16 1988 15:12`	20
	I can give you the ST pin out, I don't know about the IBM pin out. SIGNAL NAME ST IBM ----------- --- --- Read Data 1 Side 0 select 2 Ground 3 Index Pulse 4 Drive 0 select 5 Drive 1 select 6 Ground 7 Motor On 8 Direction In 9 Step 10 Write Data 11 Write Gate 12 Track 00 13 Write Protect 14 Ray

	RE: .-1 Thanks that will help. Any hints on the best place to get a generic drive? CHad
90.5	One store that sells what you ask for	PRNSYS::LOMICKAJ	Jeff Lomicka	`Wed May 18 1988 16:15`	17
90.6	Tech Specialties has generic drives	LDP::WEAVER	Laboratory Data Products	`Thu May 19 1988 03:13`	7
	Re: .4 See my note on Tech Specialties. They supposedly have some good deals on NEC drives while they last. They can also provide all the mechanicals/connections. -Dave
90.7	which brand 3.5"?	NORGE::CHAD		`Wed Mar 15 1989 15:01`	27
	Well, I never did add the second drive. I will some day. I'm actually thinking of getting a 720K 5.25" drive and using it to backup my someday-to-be- bought harddrive. I have hundreds of 5.25 inch floppies laying around waiting to be used as backup media. My real question is, what brands of 3.5" drives are to be avoided/which ones are good? I am going to replace my internal ssdd drive asap. It trashed my Master Tracks Pro disk last night and was really flaky. My friend just got a Mega 2 yesterday anyway and I want to be able to transfer disks so I need to get a new drive anyway. I've seen a NEC for 119 (in STart) Toshiba for 89, 109 Mitsubishi 86 Teac 79 Fujitsu 84 Sony 129 Jade has a name not given for 99 I want a drive that has speed control and will read the 82 track 11 sector disks. If you know any of these don't please respond. All prices above were in BYTE except for the one NEC in STart "made for the ATARI". Thanks CHad
90.8	Panasonic upgrade	MINDER::GILBERT	Systems Design & Eng Cntr @ MCO	`Mon Nov 27 1989 06:26`	24
	I have just upgraded using a Panasonic (aka Matsushita) drive, obtained by mail order for 59 pounds. I found it necessary to do the diode modification mentioned elsewhere to make the disk change detection work corretcly. (diode required as follows pin 28 -----\|>\|-----pin 2) One thing that threw me for a while was the presence of a small (2.5" x 2.5") pcb mounted on top of the screening ironwork. My eventual conclusion was that it is really there to make ATARI drives work correctly. What an expensive way to design a computer! Plugging the ribbon cable from the main board directly into the new drive worked perfectly. Some minor surgery on the case and it was up and running. Brian
