LC III dual drives

Author	Topic
~tl Junior Member United Kingdom 312 Posts	Posted - 09 Jun 2003 : 13:39:48 this question came up a while back over at the fritter ... so i thought i should let everyone know over here too ...that question was whether a LC could hold 2 hard disks ... and im quite pleased to say that it does .... the second hard disk fits PERFECTLY into the space for thew floppy drive ... and with a custom SCSI cable and a Y-adaptor power cable it works of the internal PSU too pics of my LC III - http://users.macunlimited.net/toml/stuff/lc3_hd.jpg (42k) http://users.macunlimited.net/toml/stuff/lc3_inside.jpg (56k) the only problem is that LC 475s and some (later) IIIs have 30watt PSUs which cant cut 2 HDs ... the 55watt ones from earlier LCs are alot better Orcadian MLA Division 68ks Liberated: 2

cory5412 68KMLA Comrade-in-Arms USA 4679 Posts	Posted - 10 Jun 2003 : 20:57:05 yeah... I forgot what wattage the IIsi PSU is... but I'm not surprised that an LCIII can do that... (the fitting, and the PSU also...) cool though! now youneed to make a new "top hat" for it without the floppy-hole Official 68k videographer Official MLA TourGuide "I'm just a normal computer geek who somehow landed a social life"
~tl Junior Member United Kingdom 312 Posts	Posted - 11 Jun 2003 : 07:18:07 thanks ... yeah ... i have a piece of tape over the hole at the moment ... though i will probably put int into a custom case soon ... a smaller foorprint for use as a headless server ...

emaq123 Junior Member USA 258 Posts	Posted - 11 Jun 2003 : 07:41:56 Very nice. Now the question is with a stock LC III what are the largest scsi drives that the power supply can handle? quote: a smaller footprint for use as a headless server ... Smaller than an LC III???? I'll be waiting to see the pics. emaq123 SE/30 and system 6.0.8 Now we're talking POWER!

Captain Z Mobile Ops Commander USA 637 Posts	Posted - 11 Jun 2003 : 19:37:41 Quick idea about the floppy hole: Try finding a spare LC case and get the plastic block from the second floppy drive location. You probably can pop it into the LC III's floppy hole. ------------------ Captain Z - Mobile Operations Commander 68K Macintosh Liberation Army 31 68K Macs Liberated Visit Captain Z's Starbase of EV Stuff
cory5412 68KMLA Comrade-in-Arms USA 4679 Posts	Posted - 11 Jun 2003 : 22:00:09 hehe... not only would that actually be smaller, but it would look cool AND work at the same time... Official 68k videographer Official MLA TourGuide "I'm just a normal computer geek who somehow landed a social life"

~tl Junior Member United Kingdom 312 Posts	Posted - 12 Jun 2003 : 10:59:34 exept my LC III has the 475 style lid ... so the LC II floppy covering wont work .... as for the smaller foot print ... i may make it more of a cuboid shape ... so its shallower and heigher ... ot a tower case might work Orcadian MLA Division 68ks Liberated: 2
maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 12 Jun 2003 : 18:30:43 Ah, nice. Glad to hear about someone else who has an LC475 style LCIII. Mine's the only one that I've seen with that case, and I know its the original case, because we got it brand new back in 1993.

~tl Junior Member United Kingdom 312 Posts	Posted - 18 Jun 2003 : 07:12:12 yeah ... i womdered about that case for a while too ... as all the LC IIIs in my school had LC II style cases ... but i guess near the end of production they just stuck them in the 475 cases for cost reasons Orcadian MLA Division 68ks Liberated: 2
maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 18 Jun 2003 : 07:19:44 Yeah. Btw, do you have an LCIII+ or a regular LCIII? Because from what i've heard, most of the LCIIIs with the newer style cases are actually LCIII+'s. To check whether you have one, check the CPU speed.

BTW, if you set the delay motor start jumper on the second HD, you might be able to get dual HDs working on Mac with an inadequate PSU. HDs draw max power during spin-up (most will suck down around 1 Amp on the 12V line when the platters are coming up to speed). So, if you stagger the spin-ups, then the drain is reduced. Many HDs have a jumper that delays the start-up by 4 to 10 seconds (some even delay by an amount proportional to the SCSI addy so you can stagger startups on a bunch of drives). Consult your drive's manual for the location and behavior of this jumper.

cory5412 68KMLA Comrade-in-Arms USA 4679 Posts	Posted - 18 Jun 2003 : 22:53:55 good idea :) Maybe you could get more than 3 drives on a IIsi that way also? Official 68k videographer Official MLA TourGuide "I'm just a normal computer geek who somehow landed a social life"
~tl Junior Member United Kingdom 312 Posts	Posted - 20 Jun 2003 : 09:10:47 yeah ... that should work ... hmm ... maby 3 drives in the LC ... oh wait ... no space Orcadian MLA Division 68ks Liberated: 2

nickweiss Starting Member USA 7 Posts	Posted - 15 Jul 2003 : 20:10:34 hmm, great Idea now I am going to make a floppy drive work over a network by using an old 68k as a host, sortof like my network SyQuests Nick Weiss
G4from128k Full Member USA 873 Posts	Posted - 16 Jul 2003 : 05:32:00 I'm not sure if a floppy can be shared on the network I tried this once. File sharing was not available for an internal floppy drive. Perhaps I did not have thing configured correctly. Hmmm.... I wonder if my external SCSI-based floptical can share floppies on the network? BTW, why not make a long version of the ribbon cable that goes to the internal floppy, run the cable to outside the Mac, and plug in a naked floppy drive for those rare occassions when a floppy is needed?
