Hello all, I am forming a new retro- and vintage computing group in the Seattle area. It will almost certainly be focussed north of the city centre simply because there are already groups in the south end, around Tacoma. I had originally planned to focus on one or two types of old micro...

I have two of these nice units, though only one monitor, RAM card and set of drives (one each 3.5" and 5.25"). Everything I’ve seen online indicates that the IIgs software from Apple needs either more RAM than I have or a hard drive. Is that assessment accurate? If it is accurate, what _can_ I...

I recently acquired one of these units, and was not at all shocked to get the famous "blinking LEDs" error advisory when I turned it on. Sources online seem divided about the precise interpretation I should attach to the code thus reported (7 flashes, pause, repeat), though the general consensus...

Hello all, I have been “blessed” (?) with not one but two working ‘ROM 0’ IIgses. (Yup, that’s right, whoever owned them never bothered upgrading them to ROM 1.) I would dearly love to get my hands on a ROM 3 motherboard to swap into one of them (I know a guy who did this and he says it works...

I’ve been looking everywhere for a “Commodore 4022 Tractor Printer” manual. This is for the PET-compatible printer that succeeded the 3022 model. I found the website of a vintage-radio restorer who has a copy of the service manual for sale at three times what I paid for the actual printer, but...

Hi all, First, RAM expansion: I have looked at various sites online; one even sells NOS 64K RAM upgrades for the 8032, albeit at a high enough price I'd rather try to build my own. Alas, the only expansion header pinouts I was able to find were for the 8296, with a confusing "differences...

Does anyone know what the 50-pin slot marked “ROM/FPU” at one edge of my Mac Classic II’s motherboard can be used for?

I couldn't find revision 01 IIgs ROMs on eBay or anywhere else online. This is a problem because both of my IIgses are ROM 00 units, meaning they apparently won't network boot or run the latest versions of GS/OS. (I haven't been able to track down any consistent mention of what the most recent...

For background on why I'm asking about this, see my post here in the Early Apple subforum on this site. A quick summary: I have, in addition to my Commodore stuff, some Apple II and Mac stuff. The more recent Macs have internet connectivity, and they all have floppy drives of various types. This...

This is going to need some background. I have the following: - Apple IIgs with one 5¼" drive (model A9M0107) and one 3.5" drive (model A9M0106) — how many sides of the disk do these write to, and to what formatted capacities? How many Apple II floppy formats are there? Are the drives...

I recently acquired one of these 80 column video cartridges in a box marked "16K Video Pak". Original? Danged if I can tell. Unfortunately it didn't come with a manual. Research online indicates there were a whole series of these cartridges, the earlier ones of which appear to have been for...

I recently obtained an old Mac SE (not SE/30) with an 800K floppy drive (and a SCSI hard drive in the upper bay). It also came with the SuperDrive out of a Mac II-series, I think it was a IIci or similar. I tried to install the SuperDrive into the SE in place of the 800K drive, but the Mac still...

Hi all! Just retrieved the rest of my retrocomputing collection from my parents' place in Canada, and was delighted to discover that the PET still works. On examination, it has something to the effect of "80 column mainboard" written on the PCB, but it only shows a Fat 40 screen. (Apparently...

I recently acquired a pair of Apple IIgses, one of which even works, but I have no software for it, not even an OS. I understand I can theoretically kludge my own if I can track down a IIgs programming reference and get into the built-in MLM they are said to have, but I don't know the hotkeys to...

Hi all! Just found this forum. Looks good so far. My collection: Apple stuff: - 2 ROM 0 IIgs’es, one with dead PS and the other a “Woz Edition”; 1 monitor and one each 5¼" and 3½" floppy drives; no software of any kind though. - 1 Lisa II with 5MiB Profile HD (both dead due to exposure to...
