I had After Dark and the famous Flying Toasters working pretty well (IIsi @ 25MHz, 640x480@8b, System 7.5.3r2), but after I did some other tinkering (mostly just installing games) it works OK for a second and then slows to a slideshow. Any ideas what might have fouled it up? (HyperCard came...

Back in the day, I used this with my Mac Plus and System 6. Dunno if it was ever updated and working with 7, though. https://www.macintoshrepository.org/71030-ramdisk-v1-x You could copy a system folder to it, select that as the startup disk, and restart - it would stay loaded and boot from...

Yeah I would think Pyro would fit, probably.

Hmm... no, it's a "dumb" switch but I might be able to figure something out. Are you thinking it's something like the issue at the bottom of this page? https://mactcp.net/ethernet.html

Trying to get the Ethernet card in this old IIsi working. Got a 7.5.3 install and added Open Transport 1.1.2. Link lights come on, green light occasionally blinks. Won’t pull an IP from my router and doesn’t work w/ manual configuration either (can’t ping it.) My home network is all IPv4...

*like button* Thanks!

Cool, thanks! Gonna try a thing. Be back in a while. 🤪

So a lot of macs had that single ADB port, on the assumption that you'd daisy-chain your devices. But I have an aftermarket optical ADB mouse that uses a USB->ADB adapter (the Kensington Mouse-in-a-Box) and the plug doesn't fit in the cutout of the newer ADB keyboards. I know I could use an...

Ah. TIL. This one would work then: https://eshop.macsales.com/item/OWC/133SD256168/

As of this spring OWC (macsales.com) was selling 512MB simms for $14 each. PC133 for the G4s but it should work fine in a B&W. I don’t think I’d be looking at used stuff on eBay if that’s still available.

Digging around in the recesses of my brain here but 1.4MB floppy drives and LocalTalk used to both be good for a shade under 30kB/sec so it’s probably about the same speed as the floppy drive, if not faster. Totally usable and an appreciable upgrade over swapping 400k disks all day.

Ah, interesting. Thank you for the info!

So I’ve got these two IIsi projects, and the PSU for one of them is giving me issues. I recapped them both; one works fine. The other seems to have an issue with the soft power circuit. It won’t turn on - re-seated the new caps on the daughterboard, and it turned on once but when I shut down...

I was under the impression that the 3.6v stuff didn’t work on the Plus, which requires 4.5v?

I was under the impression that the speed of the CPU was controlled separately on the IIsi by its own clock chip? (I mean, I figured the PDS slot might be an issue, but the rest of the computer I assumed was uneffected.) Do you know what other stuff is controlled by and/or messed up by the CPU...

I was reading a thread about 68882 counterfeiting and was wondering if similar things happen with 68030 chips? (I would assume yes.) I got a couple 33MHz rated 68030s on eBay for like $7 each thinking I could replace the CPU on my IIsi and "overclock" it to at least the rated speed of the chip...

Do you have other ram to try? Or can you try the existing ram in pairs? (2MB at a time?)

Nice

Is that… a serial port hard drive? That’s pretty neat.

Finished with it this morning; the IIsi is now in fully working order!
