Building a retro "Docking-Station"

Update:

I got almost everything put together today.

I dremeled out all the tabs and stuff that were in the way, plumbed in the power supply (except for the AC which i am just going to keep external) and fired up the Zip drive. My custom SCSI cable failed, i'll have to whip out the old continuity meter.

I went online after I figured out how in the heck to configure my router, it turns out there aren't many sites compatible with Mosaic 1.0.3

Any ideas on how to get a 'static' ip address (for directing a domain name) for free? I reset the DHCP lease on my DSL modem to 999 days, but something tells me its going to keep resetting at random.

Why not cannibalise one from another Mac or PC?

To get a proper static IP you'll need to speak to your ISP.

You could also use a service such as DynDNS to point a domain to your dynamic IP address. A lot of routers even offer the ability to update DynDNS automatically when your IP address changes, which is quite handy!

OOOOOH!

DynDNS looks like it would solve 3 or 4 of my problems.

I ordered some more parts and It looks like I am expanding my personal challenge to include POP3 mail and FTP. I just got an LC and an LCIII and I couldn't think of anything better to do with them 😉

Why not cannibalize one [sCSI cable] from another Mac or PC?
Sorry it took so long for me to respond to that one, I had on from an external enclosure that works fine but the connector (Cent-50) was just too big for the rear panel, there wasn't any room for it and the 7 RJ-45 jacks that need to be back there too.

When I removed the extra plastic tabs from the case, I left the ones for mounting the mobo. I have been thinking about getting a big PC board and custom etching it with an IDC-50 socket, the DB'25 socket, a mini-DIN to mini-DIN (to keep the Farallon's cable internal) plus it would give me something to mount all the jacks to in the rear. Also, if I can manage to make it double sided (doubt I would be able to do that with press-n-peel) I could put most of the Ethernet wiring on the board too.

I am going to be setting up these comps on a nice end-table I garbage-picked, basically the lower shelf will have the three stacked LC's, with the Plus on top. I am going to see if I can hook up an old SCSI CD-RW to the LCIII to run backups for the whole system.

Wish me luck!

If i don't post for a while it's because spring break has ended and I am back working and in class. I will update my site: http://irish-mike.tripod.com with relevant details. Thanks for all the support and advice, I'm glad I stumbled in here one day!

Sounds like a plan 🙂 Could you maybe do it on perf board?

So....

many....

jumpers....

Perf board would be a pretty good option if I didn't have so many traces to run, as I see it, there are about 20 that have to run for the SCSI (only 8 or 10 would need to be jumpered). Power would probably run on the back side of the board since there is a little room underneath. Each Ethernet would need 8 traces and I would leave the internal-only wiring as cat5e.

Internal being cables that don't go to the outside (farallon to router, hub to router, farallon to external DIN connector). In any case, that project is a long way off. I also couldn't find a PC-mount 120VAC to 8VAC transformer that could handle 800mA, so I am probably going to install a coax power jack on the back panel and leave the wallwart for the hub on the outside.

That sounds a lot safer.

I just ordered some parts from a rediculiously cheap place online (http://www.halted.com). I got CEN50-DB25 SCSI cables for $1, CEN50 terminators for 4/$1, and Internal-External IDS50-DB25F 4/$1 and crimp-on IDS50 sockets 20/1$ (no more fooling around with wadding up extra cable, I can make custom lengths and spacings).

I will probably update my site later this afternoon.

Ok, so I didn't update... I did find out that my LCIII works perfectly with a 7 disk external hard drive array I picked up. Its an HP, circa 1996, 5 4.5 gig hard disks and 2 (full height) 18 gig disks. The thing sounds like a pair of jet engines while it's on.
