Posted by: K55 on 2017-05-05 17:18:42with the wider board, Is it going to run into the ethernet/usb jacks?It goes under the raspi, but it should be fine 😉 V1.5: I got the correct floppy power connector from the SCSI2SD guy so its thinner now (aka around the width of a raspi B+-2-3) 😀  Just ordered this version, so I should have 10 or so copies by next month. | |
| Posted by: Themk on 2017-05-05 18:07:42 What PCB order service did you use K55? Also, what are you doing your designing in, what EDA program are you using? | |
| Posted by: K55 on 2017-05-05 18:38:30 CAD, but the old version. I'm trying to learn OrCAD and Altium Designer also. Its really you use what you find most conformable. They all arent super user friendly, but altium designer has the best toolkit for really testing a design (with rules and the like). I order almost all my pcbs from dirtypcbs, or electrow usually. This time I used electrow. | |
| Posted by: Themk on 2017-05-05 18:40:15 I've been using KiCAD, it's okay but I am looking for something else kinda. IDK. Thanks for the info. | |
| Posted by: Trash80toHP_Mini on 2017-05-05 21:28:26 Do you use free versions that are good up to certain board size limits for open source projects like this? What are max sizes for PCB layouts and board fabrication within that licensing scheme? Most projects seem pretty tiny to me. I'm used to seeing a lot of DIP 74LS and discrete thru-hole components on boards no smaller than a short 8-bit ISA card. 100mm x 100mm seems tiny. :-/ | |
| Posted by: techknight on 2017-05-06 05:06:00 I used the last cracked version of eagle before autodesk acquired them and turned it into a pay as you go service which seems to be "catching on" these days. | |
| Posted by: Trash80toHP_Mini on 2017-05-06 07:31:37 Landlord notions of Intellectual Property protection have been around almost forever.*** oP hooked me up with a full, dongled version of PowerPCB to run on my '98 box. To run multiple seat configs back in that day, PADS only provided one key and all sessions had to be actively networked to the dongled machine. Good and bad there, you could use X number of sessions at any one time on a much greater installed base of CAD seats. Almost nobody was doing this level of work on an amateur basis in the 90s as compared to today, things really have been kicked into high gear by Rpi and the fruit loops. At any rate, from what I've gathered in the past, I'll need a fully lic . . . erm . . . dongled package to do Gerbers for a PCB the size of the DiiMO/TwinSpark SE/30 adapter board. Is that still the case? What might the options be for getting a larger board made? It may need to be four layers as well, has anyone gone with either upscale option from SEEED or the like? *** auto-tldr'd a mini-rant again. OOPSIE! Old timers will probably have heard this already, but newcomers may be interested: IIRC the user group teachers had to boot the PhotoShop sessions sequentially on each machine while networked and then disable networking in order to move on the next machine to start that session in the classroom. Adobe didn't bother doing that with Illustrator in the day, but now to upgrade past my licensed copy of AI10 I'd have to rent PhotoShop in a Suite along with it too. That's never gonna happen, never used it, never will. As a licensed FreeHand user I had the chance to upgrade to MacroMedia's FreeHand Graphics Studio which included Xres so I stubbornly used that instead. Because Adobe never anted up with a similar deal on their cash cow for loyal users of AI and its related products, so far I've refused to even play with any of the many copies of Photoshop I've acquired on various HDDs in the collection. PTUI! 😛 Gotta get into the GIMP! | |
| Posted by: Rajel on 2017-05-11 08:29:03 Ooooh, so very interested in this for my Powerbooks. I saw the original X68000 project recently and thought it might be adapted to the Macs, glad to see someone's already running with it! | |
| Posted by: 360alaska on 2017-05-11 08:47:15 I use Designspark: https://www.rs-online.com/designspark/pcb-software | |
| Posted by: Trash80toHP_Mini on 2017-05-11 09:49:37 Nice, never heard of that one. How's the Mechanical CAD package? | |
| Posted by: 360alaska on 2017-05-12 04:11:05 Mechanical cad? Not sure, I just design and layout boards in it. The other thing I like is that you can design a board without making a schematic if you want to, for very simple boards and adapters this is a time saver. | |
| Posted by: Trash80toHP_Mini on 2017-05-12 10:27:36 https://en.wikipedia.org/wiki/DesignSpark_Mechanical I've gotta try this one out, it seems it has a modeling clay approach to building designs, sort of a 3D version of Illustrator's design-combine-divide 2D shapes model. Is that how other modeling package tools work? I was really excited when I saw these features demo'd in the Dreams 2D CAD package for the Mac well before these operations became available in Illustrator or FreeHand. First time I've heard of the Freemium marketing/pricing strategy as a thing. It's a refreshing concept when compared to (crippleware) demo versions model from back in the day. edit: it sure would be nice if they listed linkage to system requirements for the programs somewhere that page. :🙂 | |
| Posted by: Rajel on 2017-05-15 13:29:05 Yeah, it's kinda nifty as a business model... almost wish Sketchup had a subscription model because I need more than the free provides, and even the student license is too high. Fusion360 at least has a free (but fully functional) hobbyist license you just renew every year. Still trying to figure that out for my 3D priting designs. | |
Posted by: Themk on 2017-05-17 17:28:59CAD, but the old version. I'm trying to learn OrCAD and Altium Designer also.When you say "CAD", what program are you specifically referring to, A lot of them have 'CAD' in the name. | |
| Posted by: kerobaros on 2017-08-24 19:07:32 K55: did you ever get your boards assembled? How'd they work out? I'm very interested in this project. | |
| Posted by: mactjaap on 2017-08-25 12:54:24 Yes. Same for me. I also like to know if we can jump in. I work a lot with RP and clones. This would be a nice extension. | |
| Posted by: K55 on 2017-08-27 09:14:32 Still a work in progress. I've been trying to secure a supply of the bus chips so that I can make more than 2 of these at a decent price. Taking a bit but should be done soon. After I get a batch of these done I'll release the eagle files. If you need one /right now/ I think there's a guy in japan with a board but its proprietary connector for the pc98 afaik. :approve: | |
| Posted by: mac512 on 2017-11-11 07:37:47 So, how are things going on with this project? I'd love to try it in my LC III... | |
| Posted by: K55 on 2017-11-14 12:30:59 Sorry for not updating more :-/ Been busy with life stuff. Anyway I've made a new github (lost access to my old one) so this is the first thing on there. https://github.com/fran-cap/RASCSI-68kmlaver That has the eagle files, the extra libraries I used, and information about parts. I did a cost estimate and it would come out to around $35+s/h per so for each board, perhaps cheaper if I can find a good supplier. Going to try and post more stuff soon. | |
