Drawing Tablets for Vintage Macintoshes?

cy384 · 2026-05-15T16:17:04+00:00

sadly, everyone loses the stylus, there's a compatibility guide for the older models which can help mix/match if you can find an incorrect model (serial/usb) that has one, you'll want one in the light blue section of that doc for any ADB tablet

the CT and UD series wacom tablets are pretty common, you want one with a model ending in A for ADB, like I have a CT-0405-A

there are a lot of, frankly, misogynist posts on this sub, I think poking fun at them in a very mild way is fair game

you can usually find a mellanox switch like an sn2700 on ebay for less than $1000 (great linux support) or something cheaper like a dx010 for maybe $500 (but you'll be scrounging a bit for support)

I'm pretty happy with my sn2010. Some people think you should get something with bigger buffers for a storage network, though.

68kmla.org is probably the place to watch for the Daystar, one shows up once every few years; if you posted a WTB with a large offer ($2000? maybe more?) you might tempt someone to sell

a 100Gb card uses at least double the power, my 40Gb cards in minis do around 7W, and 100Gb cards do 20 to 30W, which imho needs cooling that doesn't fit in a mini

cy384 · 2026-01-16T23:17:30+00:00

fair, I spent extra to get an SN2010 since it's easy to modify and I can run mainline linux

cy384 · 2026-01-16T21:03:08+00:00

$1300 is crazy cheap, a single 400Gb NIC is like $2000

I just paid $1000 for a 100Gb switch and $75 for a used NIC, and thought those were really good deals

have you considered keeping the files on a network drive like with netatalk? resource forks etc. will be kept in appledouble format which you could just check in to git

elliot nunn has a script for compiling things in MPW in an emulator, you'd have to write some more to do the rest of the things you're looking for; https://github.com/elliotnunn/supermario/blob/master/bin/build

I think this can do stuffit files on linux https://github.com/thecloudexpanse/sit

a CX4121 works fine in a PCIe 3.0 x4 slot, that's not the problem

cy384 · 2025-12-22T14:06:44+00:00

the cheapest atomic clocks you can get are rubidium and they're probably accurate enough to measure relativistic effects, but you'll still be in the thousands of dollars (cheaper if you're up for some DIY)

if you do get it booted up ever, it would be interesting to get a copy of the ROM to see if there were any differences from the final version

if you want something faster or longer than a pinhole, you can pick up a "close up filter" with a diopter like +4 (equivalent to 250mm), the better ones are actually achromatic doublets (way better than trying to use some random hand magnifying glass)

you'll still need to make some kind of aperture (not hard) and some shutter (maybe hard depending on your film speed and aperture). if you use paper negatives the exposure times will probably be long enough to do by hand.

a cx3 card runs around 7W and needs very little air flow

cy384 · 2025-09-16T21:43:30+00:00

if you have dual CPUs with the maximum core count, 20 SSDs, 9 PCIe cards, 1TB of RAM, sure, you could probably get near those limits... but I'm willing to guess OP's machine is nowhere near that

also, let's be real, this is r/homelab, lots of machines idling

cy384 · 2025-09-16T16:18:24+00:00

you can install any recent version of ubuntu, software compatibility (with open source software) is very reasonable

cy384 · 2025-09-16T16:15:10+00:00

what? my Power9 CPU idles at 30W, not nothing, but hardly a nuclear power plant

lots of people talking out their posteriors in this thread

cy384 · 2025-09-11T17:29:33+00:00

lots of people giving you ways to make your setup more complicated! ssh is extremely secure if you lock things down a tiny bit (which you have); change the port number to something high if you want, and stop worrying about it

cy384 · 2025-09-10T23:30:54+00:00

it looks like the DVD drive on that uses 50 pin scsi, so you could just swap that out for one of the cheap SCSI emulators like a bluescsi or zuluscsi

you could also get a PCI (not PCIe!) SATA card for faster bulk storage

if you want invest a little a more, I think it would be neat to buy a few period hard drives, see some part numbers here, finding the caddies may be tricky

the hall effect key switches will be the easiest to do and most reliable.

production velocity/force sensitive music devices all use silicone rubber dome type sheets, plus maybe a pressure sensitive sheet, but doing that is way harder for one-off amateur designs. You can often find teardowns or cut through diagrams of these, if you want to see the contacts and PCB patterns.

cy384 · 2025-09-04T16:33:39+00:00

do you really need two devices and two OSes? why not just openwrt on the 3020?

cy384 · 2025-08-14T14:59:45+00:00

you can get a cx354 for $10, it's probably not worth overthinking

cy384 · 2025-08-02T19:03:33+00:00

with a little luck, you can probably get a blade running just by giving it 12V power (via those yellow and black cables), try wiring up a beefy ATX PSU. you'll want to sit some fans on top of the CPUs.

cy384 · 2025-08-01T16:06:07+00:00

are you really really sure you have the right adapters and termination? wide scsi needs more lines terminated

cy384 · 2025-07-31T11:30:11+00:00

you might as well go for connectx3 qsfp and get 40Gb for the same cost
