Yup. But that, combined with the datasheet for the processors, should be enough for me to start.

Thank you, all. I was hoping it was relatively straightforward (well, as straightforward as a IIgs processor upgrade card might be). So far, I've been looking at this page, mapping the pinout of the processor socket on the TransWarp GS card to the 40-pin socket for the cable to connect to the...

Does anyone know the wiring for the CPU ribbon cable that connects a TransWarp GS card to the original CPU socket on a IIgs mainboard? It's a 40-pin connection on the TransWarp card, I'm just wondering whether there's a published diagram for insertion into the DIP socket at the other end...

When I installed the Cirtech card backwards and it went "pop," the seller asked me to mail it back to him so they could check it out. They verified that the card was very, very dead now, and then sent me an entirely new one at no charge so that I could get to using it. Very nice person. I...

I have the same reproduction Cirtech card, and I did the exact same thing you did: installed it the wrong-way round. In my case, I blew up the card (released some magic smoke) but didn't do any harm to anything else in my computer. I fear you may have been unluckier than me, and you may have...

I was never able to get the downloaded GS/OS images linked to from the BlueSCSI website to work. I ended up using a blank 32 MB ProDOS image set as HD60 on my BlueSCSI, then installing GS/OS 6.04 to that from scratch from the floppy images, using a FloppyEMU. My BlueSCSI doesn't have any...

I am exactly the sort of person who still keeps USB optical drives around; I have two, maybe three, all working. I just didn't expect them to be an option. I also have two IDE hard drives still kicking around in my Old Drive Box. Is it a bad idea to try swapping one of them into the G4? Does...

"dir hd:,\" returns "can't OPEN the DIR device" . This is slightly different? "dir cd:,\" returns "DISK-LABEL : read of block0 failed can't OPEN the DIR device ok" I might be able to find a Firewire drive or enclosure at the local electronics flea market in a few weekends, although I...

A quick follow-up: it would theoretically be fine with a DVD drive, except that one is refusing to spin up, either. Argh. Well, either I pick up another optical drive at a flea market or from Goodwill, or I figure out how to repair an optical drive. Or both ... Thanks for your help...

Thank you! I can get into Open Firmware (let me know if any of the version information would be helpful), and I tried the commands you suggested. If I type "boot cd", it returns DISK-LABEL : read of block0 failed can't OPEN: cd ok It returns the same error if I try "dir cd:,\" as well. I...

(First off, if this is a duplicate or there's an easy answer to this and I'm just not seeing it, please feel free to point me to a link.) I'm trying to get a Power Macintosh G4 tower (this model: https://everymac.com/ultimate-mac-lookup/?search_keywords=PowerMac1%2C2) working. I bought it a...

I was about to note that the client software on the surl-server Releases page () includes a telnet program, but then I saw this portion of the release notes: When I've used it in the past, it's worked well. I hope it returns soon.

Yes, as far as I know surl-server can be pointed at any serial device you have. I suggested the USB-to-DB9, DB9-to-MiniDin-8 chain simply because that's what I had on hand when I first set it up. Thanks for suggesting the Pi HATs, I don't have any experience with those yet.

Wires: You'll need a computer with an Internet connection on which to run the server, a USB-to-9-pin serial cable, and a 9-pin serial-to-MiniDin-8 serial cable. There are pre-configured server image downloads for a Raspberry Pi, which is what I use - a Pi 3 or newer will work fine. There are...

I have an older Manila Gear IIgs-to-VGA adapter, but were I to buy something today I'd try BMOW's Mac Sync-inator (https://www.bigmessowires.com/mac-sync-inator/). He has instructions for using it with a IIgs as well. I line the 15 kHz VGA from my video adapter into a GBS Control box...

Hello @yomatiase, I just made an account here after reading for a while, in order to reply to your question. I have an Apple IIgs and a FloppyEmu, and I use surl-server (https://www.colino.net/wordpress/en/surl-server-a-serial-proxy-for-8bit-computers/) for Internet connectivity. It will work...
