Rybags Posted September 18, 2019 Share Posted September 18, 2019 Had a look at both in the series. He's not explained the video mapping much (I imagine there's likely plenty of docs on webpages around the place) but I don't think much of interleaving the text then attribute bytes. He did mention some graphics mapping having advantage over C64 in that it's easier to render to but I would guess 99% that he's referring to linear vs cell based bitmapping. The approach - really I think the purist legacy hardware policy is only really necessary if you want to interface to old hardware and cartridges. Given that it's a new architecture there's not really a requirement for that. So I'd be going to town incorporating as much modern day stuff as possible to keep the component count and price down. Of course it's very desirable to have 5 Volt interfacing and to make the thing such that the end user can easily do mods to it. At the end of the day though, it's yet another platform in an already thinly spread support market. We have a similar situation here with VBXE and the onboard and external CPU accelerator options - the hardware eventually evolves from concept to reality but then the problem becomes selling units then the problem becomes creating software to use it.

AMenard Posted September 18, 2019 Share Posted September 18, 2019 His project is interesting, but at the end of the day if I want to code retro, I'll do it on a retro computer. I have a nice C128 setup with a U2+ that add 2mb as an REU that I use to code in 65xx Assembler for old time sake. I also use CBMStudio on my PC for ease of use. I'll probably get an Ultimate 64 to futureproof a breadbin before I buy a totally new platform. I also code on PC with Allegro 5 in C/C++ which is pretty old school in its graphics and sound management. I love the 8bit guy YT channel and I've watched all of his videos. Like him I intend to write a multi-plateform game (C64/128, PC, Atari 8bit). But I'd go with an Ultimate 64 upgrade before buying into a totally new platform. 1 Quote Link to comment Share on other sites More sharing options...
+mytek Posted September 18, 2019 Share Posted September 18, 2019 What I quickly noticed when watching his 'Part 2' video, is that there is very little that the 8-bit Guy is doing himself. Board layout, custom chip/module design, and even the OS is all being handled by someone else. I'm also imagining that the better demos will be written by a 3rd party as well. So his role has been relegated to that of a project manager. Not a bad thing, but not what I pictured when he first started talking about the project. 1 Quote Link to comment Share on other sites More sharing options...
Preppie Posted September 18, 2019 Share Posted September 18, 2019 Given that there's so many add-ons to multiple old systems, I like the idea of having a new standarized 'super-8-bit' system. Also, I'm a bit of a purist. I like retro computers to stay un-moded for future generations. I don't mind it when 'c' grade systems are modded, but seeing a mint retro system with the case cut to add a mod hurts my heart . 1 Quote Link to comment Share on other sites More sharing options...

For those that don't like emulators I always liked the idea of an FPGA system like the Commodore One that could transform itself as needed into whatever hardware architecture you want. I used to be on the mailing list for that back in the day and it seemed like it never got fully baked.

gozar Posted September 18, 2019 Share Posted September 18, 2019 I really like the concept, and will probably buy one once it's finished. That being said, I think there is merit in going with the emulator route. The price would easily by under $50, and software is easier than hardware. You could use your own OS (check out Risc OS for the Pi) and boot directly to basic like the good old days. Or, use Linux in the background to handle all the messy networking stuff but still boot to a Basic prompt. I set up a Raspberry Pi with Atari800 in this fashion so I can play around with hardware I don't have (PAL and Stereo). The goal is great for his project is great though, a simple machine to get people excited about technology. Quote Link to comment Share on other sites More sharing options...
tschak909 Posted September 18, 2019 Share Posted September 18, 2019 I support the project 100%, and he has already asked me to port PLATOTERM to it, which I have already done a bring-up. It uses the 640x480 256 color mode, and just needs a form of connectivity to complete it. -Thom 3 Quote Link to comment Share on other sites More sharing options...

A modern 8-bit doesn't interest me in the least. But more power to those who are interested. And modding cases, to me, is a joy, if it's done professionally to look original, and what should have been according to original designs, before management decides to take short cuts and ruin it all. Like my 1200XL with PBI. I have my other 1200XL that is mint-original though. (as far as the case) I just find it much more satisfying to mod original equipment than coming up with something new, including stuff like the 1088. I'm intrigued, but not interested in one for myself. I've already got my dream-machine 8-bit that I made into a dream-machine myself with my own hard work, exactly the way I want it, and still 100% compatible with the stock original and I did a damn good job and it works perfectly and looks perfect. I find much more satisfaction than starting from scratch with all-new boards and cases, etc. The machine I fell in love with is still there, just added too, and nothing taken away. But that's me, and again, more power to all those who want something new obsolete instead of old obsolete.

I totaly understand your viewpoint, I'd never think less of someone who did what they wanted with their own gear. It even excites me for a brief moment to see a super modded system, but then my conservative side kicks in. 1 Quote Link to comment Share on other sites More sharing options...

I use the term only in the context of what the rest of the world considers obsolete or not. Personally, my 8-bits are anything but obsolete, I still use them for everything but the internet (maybe even that someday with Contiki), for my finances, writing and graphic art. If I can use it and it gets the job done, to me, it's not obsoloete, just vintage. Using my vintage computer for all my digital chores makes even those chores fun, because I get to use the machine I love, and be quite productive while thumbing my nose at modern computers. I was just laughing to myself last night because I saw a commercial for an internet site you can go too, to do all your financials and it even can keep track of your total net worth...in the mean-time I already have an 8-bit that can do all that using Syncalc, Synfile and My Personal Net Worth programs that do it all quite well, in spite of being 35-40 year old programs. And no chance of people hacking my account and personal data! I'd call that state-of-the-art, in my book, not obsolete. Quote Link to comment Share on other sites More sharing options...

And more likely than not a common thief wouldn't know what to do, if they even thought of personal data, so they'd have vintage stock to sell on ebay or Craig's list or try and pawn for far less than they are worth. It would only be the loss of my vintage equipment and very little chance of data theft. They may have the floppy or CF card with the data, but knowing how to extract or load or use it is another thing entirely for some punk thief.

That is why when I added the Sophia board to my 800XL, I did not alter the case. I just screwed the case back together with the ribbon cable sticking out. The way the 800XL sits, I can not see it coming out of the back. Worked out pretty good. And I REFUSE to AV mod my heavy sixer. I have other 2600s for that. That other thing plugged in is the USB power adapter. YES, it is worth every penny. Works flawlessly.

I did a quick search for the sources and they appear to be on GitHub. I might try to see if I can port them to one of my own FPGA boards. Thanks for the heads up!
