Math You Posted March 21, 2012 Share Posted March 21, 2012 I just found this video about an Amiga FPGA 'Computer on a chip'. It was designed by Jeri Ellesworth who designed the Commodore 'Plug & Play' TV joystick game. http://www.youtube.com/watch?v=5uaDzF99a80 Interesting thing about the Amiga is that the faster ones could also emulate the Atari 800 and Atari ST using software (and probably a lot of other things aswell). I really hope this gets made one day. It would be a fitting tribute to Jay Miners work. 1 Quote Link to comment Share on other sites More sharing options...
Mark Wolfe Posted March 22, 2012 Share Posted March 22, 2012 wait a sec, don't we already have this via the MiniMig: http://amigakit.leamancomputing.com/catalog/product_info.php?products_id=777 Quote Link to comment Share on other sites More sharing options...
JamesD Posted March 22, 2012 Share Posted March 22, 2012 Jeri's project actually pre-dates the MiniMig. Quote Link to comment Share on other sites More sharing options...
Math You Posted March 22, 2012 Author Share Posted March 22, 2012 I think Jeri's version was going to be an official Commodore product with a similar price tag as a Plug & Play TV game. It's a shame it never got made. Quote Link to comment Share on other sites More sharing options...
Rybags Posted March 22, 2012 Share Posted March 22, 2012 For what it is, the modern day Amiga evolution is just too expensive. An FPGA solution allowing a setup for under $100 or so for legacy support e.g. 68030 ~ 40 MHz and AGA would have been great. Quote Link to comment Share on other sites More sharing options...
carmel_andrews Posted March 22, 2012 Share Posted March 22, 2012 perhaps this is just an amiga version of the c=1 (which i think the same person designed) but smaller Quote Link to comment Share on other sites More sharing options...
matthew180 Posted March 22, 2012 Share Posted March 22, 2012 For what it is, the modern day Amiga evolution is just too expensive. An FPGA solution allowing a setup for under $100 or so for legacy support e.g. 68030 ~ 40 MHz and AGA would have been great. That won't happen until FPGA costs come down. Small FPGAs, like 500K gates or less (Xilinx Spartan 3, Altera Cyclone II/III) are not too bad at about $25 to $35 per FPGA, but when you start getting in to the 1M gate devices, or the newer faster FPGAs, the costs start to rise exponentially. A 32-bit chip like to 030 requires a lot of gates, and the other custom ICs in the Amiga would also require a ton of gates. I don't even know if I would try it in an FPGA smaller than 1M gates. Also, the dedicated ICs in the Amiga had their own local RAM, which for the FPGA means multiple wide address and data busses, which means and FPGA with lots of I/O, which means a fine-pitch BGA package, which means 3/3mill trace/space, which means minimum 4-layer boards and complicated layout, which means more assembly costs and fewer options for having small quantities of boards made, etc. It goes on and on, and is not as simple as saying "that FPGA is big enough and only costs $45 at Digikey..." Low demand hobby projects are always going to cost more and cannot be compared to "consumer electronics" that are being made in batches of 50,000 over a 5,000,000 production run. Sometimes I am absolutely amazed at the cost (meaning how "cheap") some electronic products cost, especially when I start thinking about what it would cost me to produce the same product. Hell, as a hobbyist, you can't even get a 2"x2" circuit board made for less than $15, and compared to some electronic gadgets I have bought lately, that circuit board alone blows the whole budget! I guess my point is, you can't be a classic computer hobbyist and be "cheap". The computers are old and limited and the gear costs money. If hobbyists really want to merge new technology with the classic computer stuff, they have to be willing to pay for it otherwise no one is going to do it. No one has the time or money to do FPGA design, development, production, etc. for free or "on the cheap". I would estimate that, for one person to reproduce an Amiga 4000 on an FPGA (working on just the HDL via a devboard) would take at *least* a year of dedicated "hobby hours", i.e. time in the evenings and weekends. And that is if they are really good at HDL and not just starting out. Once that is done, at least another 6 months to get an "off devboard" working prototype, and a final 6 months to set up a small production run. So, assuming the HDL requires a $80 FPGA alone, plus board and production costs pushing the bill of materials to $150, what would the hobbyist market be willing to pay that person for 2 years of their life? IMO, anyone who makes something like that should get at least double the materials cost, so in this case selling for $300 would not be unreasonable, but my feeling is people would balk at that price (even though it is fair). We are disillusioned with the cheap cost of modern throw-away electronics and fail to realize that those economics cannot be applied to everything, *especially* classic computers and hobby electronics. I think Jeri probably stopped due to economics. If she was being paid by a company, they probably realized the market was too small or unwilling to pay a price that would let the company make a profit. Or simply the requirements were too high, or the project too large for one person. You have to remember, all these calssic computers were built by *teams* of very smart people, and for one person to sit down and reproduce that product from datasheets is a monumental task. IMO the Amiga is border line as being too big for one person. Well, that turn into quite a rant. Sorry for letting my opinions run away with me. 7 Quote Link to comment Share on other sites More sharing options...

The MCC-216 only emulates the 68000. I could certainly do that at a higher MHz but emulating a 68030 & math coprocessor would take a lot more real estate for added instructions, cache memory, etc... Whether or not it would still fit on the MCC-216 I don't know. Minimig will run on a DE1 development board. Quote Link to comment Share on other sites More sharing options...

+Gemintronic Posted March 23, 2012 Share Posted March 23, 2012 I'm selling my MCC-216 and plan to get a Turbo Chameleon for myself. Both products have beta support for Amiga but the Turbo has read/write support on disk images. Quote Link to comment Share on other sites More sharing options...

Nebulon Posted April 17, 2015 Share Posted April 17, 2015 Well, it sounds like she came away from it with a healthy respect for the Amiga. She's on the list of attendees for the 30th anniversary Amiga banquet in California. Quote Link to comment Share on other sites More sharing options...

IMO the Amiga is border line as being too big for one person. As shown by her Amiga DTV prototype, it could be done by one person.

thetick1 Posted April 3, 2018 Share Posted April 3, 2018 This is now my prized possession. DSC09391_sm.jpg I'm jealous. Anyway I should just be happy to finally have a working c64dtv. Now I just need another preferably v3 to mod with an SD Card. Quote Link to comment Share on other sites More sharing options...
