if you are looking at open source 68000 to 030 accelerators, have you considered adapting the terriblefire TF536?
It works in the Amiga 500, 2000 and Atari ST right now, and probably is a lot more well-tested than this one.
Here's the link to the EEVBlog video about cheap PCBs
JLCPCB Prototype Inspection
I'm really not underestimating costs.. apart from the connectors, this is about as cheap a board as you could ever possibly hope to make.
I have also ordered smaller boards on oshpark for literally a couple...
I really disagree. There are many many examples of far more complicated boards for the hobbyist market being sold right now, presumably at a good profit. Check some of EEVblog's videos.. he got 4 layer boards the size of a motherboard made for $20 each - delivered in 5 days. Getting the board...
There are practically 0 expensive parts other than the connectors on the adaptors. The PCB itself can be ordered for a couple of dollars each. This would be an extremely cheap and profitable board to sell - but nobody is doing it.
After a year or so of no movement, I think it's time to make...
Someone has the ability to push out PCBs and they don't do it - we've seen actual boards being distributed to a select few.. all that is required is to repeat the process.
And if it's too hard/time consuming, give a license to someone else! And if they don't want to even do that - release the...
Yep I bought some of those from him!
There are a few completed projects just crying out for release - and it's getting to the point where classic macs will die out as a hobby soon without some momentum.
The twinspark repro board
The greyscale board for the se/30
IIfx ram sims
Something funny about mac projects where nothing ever ends up being released, even when they are completed. Gamba round 2 I guess.
BMOW projects and SCSI2SD excepted
You'll have to sign up with them yeah - could just use dummy info I suppose. It really is the best way of getting the design out there though - you can order pcb's shipped worldwide for a couple of bucks - which is way easier and cheaper than making them at home.
From what I gather, it has to...
joethezombie: I like your general ideas, but selling simple memory chips on a SIMM socket should not be something anyone should be upset about or feel that they can protect. They are not selling the programmer.
If you want to support dougg you know where to buy it (I did).. but if you want to...
I think it's totally up to joe what he does with his work.
I've already got a Twinspark I paid heaps for anyway - it'd be nice if everyone had the same opportunity (daystar + ethernet will set you back $150 on their own these days).
Not sure about the licensing bit.. you still want to ensure it is worthwhile making them for sale - or none will get made.
Offering a PCB design on OSHpark would be a good start anyway.
There is a project for the amiga/atari st called the terriblefire 530 that has the right approach to all...
I think he's wrong. The IIGS isn't a better machine.
The original 128k should have been 512k, and the mac 512k could even be used by people today for productivity (e.g. write a letter or a book). Not so the IIGS.
e.g. Microsoft word 5.1 is pretty close to modern versions.
Game music also...
