  1. The manual indeed says it is an AUI port. Thanks much for info. $14 from china shipped is a great price/bet.
  2. This little box came with a IIci I picked up from Craigslist. It has 2 ADB ports at one end, and 2 telephone ports at the other. And an on/off switch. From what I can tell, the idea was that you plugged your office phone into it, and this into your Mac, and then if you were traveling or something, and wanted the Mac to wake up, you could call it, and it would turn it self on, then turn itself off after the call (using "Power" switch wire in the ADB connection). it's about 2.5 inches by 1.5 inches. Telephone plug is basic stuff, and this has to be dead simple inside it. Might be a fun hack in t
  3. Does anybody know if thin coax internet can be converted to RJ-45? I see lots of adapters on Amazon going for between $20 and $100. Lots seem to be for cameras? has anyone done with this retro computers?
  4. Thanks for that info. I am going to put that on the to-do list for the future. "premature optimization" being what it is... It may not be worth doing of course.
  5. ah, err, umm, so it seems that what really happened was I replaced one of my files on the "build Mac" at some point in the development of the icon button, and forgot that on the build Mac I had been un-defining the macro for 'debug' statements. So they were all getting written out again. And that's actually the biggest chunk of that data. the original 2-state icons accounted for 95k->102K (about 7k). Then 30k of debug statements started getting compiled in. Then the 3-state icons bounced it up to 150K (+18k I guess). It's down to a svelte 116K again after turning off all levels of logging.
  6. Minor update: I modified the CDEF to have 3 pre-generated graphical states (6, because B/W provided separately from color): Active, button not pressed Active, button pressed Inactive I think the inactive representation is better now if you are on a color Mac. more what you would expect (err, right?). Visually, nothing changes for B/W Macs. I meant to mention the other fun part here of this icon exercise: finding a graphic program to make the icons with. I tried SuperPaint, and quite liked it, but it didn't handle color (I believe a
  7. What's fun about this project is that I get to learn new things little by little. This week I made my first CDEF. If you open an app with ResEdit and see a CDEF, it's a boring looking thing. Just code. What it is basically a custom UI Control. In this case, I had a Start (sync) and Stop (sync) button, and wanted to add a Refresh (file list) and a Delete (file) button. But text buttons take up quite a bit of space. And this is a Mac, it should be graphical, right? Well, turns out there is no graphical/icon button in the Classic Toolbox. (Maybe later? Carbon?). So you have to roll your own.
  8. ha. I thought "That's crazy, he'll never be able to do that from resedit; it's not going to be in a resource!". But yeah, if you are willing to go into the de-compiled CODE like that, then sure! Still kind of amazed you found that.
  9. You got it working? That's great! Congrats.
  10. This was in a Mac IIci I got in a local craigslist purchase. It has a manual, 3 floppies (looks like original 4.0 version and a working disk with 4.2). The variant in the machine was DB15 + coax. I've never worked with either of those kinds of ethernet. Skimming the manual, I get the feeling I'm not going to be able to convert those to work with an RJ-45 type adapter. Is that a safe assumption? Board appears to be in very nice condition. Is anyone looking for something like this? Hmm. Looks like there are traces into a blank area on the board where the RJ-45 plug woul
  11. This is a mysterious computer. I have it plugged into a power strip now, and leave it in the "server" mode (push button screwed in). It seems to be getting more reliable. It ran all day yesterday pretty much without problem. The only th ing was, when I shut it down, it would restart itself about 15-30 seconds later (hence the power strip). Today, it turned on IMMEDIATELY after flicking the switch on the power strip. It hasn't turned itself off spontaneously since that first time. What's going on in that PSU?
  12. So I put all the cards back in and sealed it up, and thought I'd try leaving it in server mode a bit. About 5-10 mins later I heard the fans start up. Turned on the monitor, and there it was. Beautiful! 32 MB RAM. Not sure how much is on that cache card. System 6.0.8 seemed snappy. Goofed around with it a bit, and maybe 5 mins in, it just turned off and hasn't turned back on since then. Monitor is pretty awesome. Ugh. Now I really am going to have to fix the thing up.
  13. I only used CW a bit in the 1990s, on a PPC clone. I have kind of fond memories of it, but no recent or deep knowledge at all. I'm not sure what the minimum requirements would be, but it might not be that pleasant on an SE/30. I found this on Macintosh Garden: So that makes it seem possible. try it out! Plus you can do Java. I understand that's an up and coming language.
  14. Yes, this is that one. I'm like really bad at desoldering things, and not much better at soldering them. I fried an Amiga 1000 daughterboard desoldering a chip, and I can't quite get the courage to do more (yet). I think I'll have to set this aside for a snowy day. (or until I finish 1 or 2 of these other already-started projects). Maybe I'll keep an eye out for a "parts only" IIci, but seems risky that a motherboard from any other IIci would be in randomly better shape, especially if sold as a parts machine. Thanks for info!
  15. There was a local craigslist ad for a IIci with an apple portrait display, and I've been looking for an 030 machine for dev work, and portrait display is of course pretty interesting! There was a photo of it displaying the disk icon. When I got there though, it wouldn't start up. At all. I kind of gave up at that point, but about a week later, the guy said it was now running. He had plugged it in, and came up at some point when he wasn't looking at it. He left it up and when I got there, I saw it, it was running. I brought a SCSI2SD, so my goal was to turn it off, plug that in, and hopefully
  16. That's an awesome save. great job!
  17. I haven't had a chance to do anything with a Linux VM. I did manage to get a working debug station going, thanks to help from folks here on the LC forum. Turns out you can power an LCII from an IDE drive utility thingie I already had, so behold this beauty: Maybe hard to see, but I basically just jammed the wires right on top of the wires from the PSU. And it works. Added SCSI2SD, and now I have a 6.0.8 machine with 10 MB of RAM, capable of running THINK 7 & debugger. Well, but... it turns out it is HEINOUSLY slow to start and end the debugger. Like 10-15 min
  18. I suppose in theory there was a BASIC that would run on a Mac of SE/30 vintage, but I don't know what it would be offhand. Most people would have been writing in one of these 3: 1) C 2) 68K assembly 3) Pascal For C, I would recommend either THINK C 5.0 or Symantec C++ 7.0 (which is THINK C 2 versions later). Apparently v6 is a real dog. If you have 4 MB or less, version 5.0 is going to be your only bet. Maybe even go version 3. both available on Mac Garden, etc. Make sure you get THINK Reference, it's a great help. I highly recommend Macinto
  19. ah. 7.5.5. that eats enough memory to make the difference? not hard to believe, I guess. Bummer that miniVmac only supports 8MB. I much prefer it to BII.
  20. Perfect, thanks for that info!
  21. Have you tried a custom build of Mini VMac? I use a few, this is the one I use for dev: -br 37 -t mc64 -m II -hres 1600 -vres 640 -magnify 1 -sound 0 -ndp 0 -speed 3 -as 0 Translation: Mac II, 1600x640, magnify on to start, 8x speed, 8 MB RAM (I'm not sure which of those got me to 8MB, looking back on it). That's enough to run 6.0.8 + THINK 7 + Debugger + 2-3 little applets (import file, export file, that sort of thing). I don't have macsbug installed on this system though, so not sure what your mileage would be there. And also, it's not a Mac Plus of
  22. It isn't the same maker. I've had that kit (same parts, very similar box) for several years. I temporarily cannibalized a molex adapter and hot wired it right into the +5, +12, and ground on the motherboard. Started up immediately. No sound, but it powered the board and the 3.5" HD. I didn't try a floppy. Also didn't try the ethernet board. Did do some serial work, the ports seemed fine. Not the most elegant solution, I grant you. I'll have to get something more permanent going.
  23. Awesome! I HAVE one of those. And it starts up! Woot. Double-woot: it has 10 MB. I'm off to do some debugging! Thanks everyone!!!
  24. Yeah, that's going to be taking the virtualization of this to a new level. To develop code for a 68K (real) Mac, I write the code on an ARM based Mac, compile and debug on a Mac emulator, which itself is running in a virtualized Linux environment. Looks like there now is an M1-compatible VM tool: https://eshop.macsales.com/blog/72081-utm-virtual-machine-on-m1-mac/ https://mac.getutm.app Is this accurate though? It only supports max 4 MB? That's too small to run THINK C++ 7 and debugger.
