  1. One of the big diffs between this ‘project’ and efforts like Foenix is the lack of cohesion and a polished social media presence/professionalism that is very much present here and absent there. I’m guessing/hoping this forum will remain and that some other, well rounded individual can step up to fill the void. Sadly, this tells me that the project is not as close to producing fruit as we hope and maybe the timeline is just too far out at this point. Having lost a parent 5 years ago, I’m familiar with the challenge and the perspective that it adds to an often already full docket of responsibility, so respect and condolences are in order above all.
  2. He also cited an intermittent issue with SD card access; also deemed a software issue. These (timing) types of issues are dreadful to troubleshoot when the SW and HW ‘teams’ are not collocated.
  3. That’s great feedback, thank you. Unless you are a professional, none of the recurring-fee based subscriptions make sense to me but 10 years of upgrades for $300 sounds reasonable. Probably not supported on my 8 core circa 2008 MacPro so it will be a matter of whether or not it will run well enough on a 3 yr old MacBook Pro w 16GB. Any thoughts on that? (It’s just for 30 min YouTube clips).
  4. Since I don't fool w/Linux and I'm not up for paying a subscription fee monthly, I've been considering Adobe Elements. All I really want is the ability to do multi-camera and picture-in-picture. I bought Final Cut Pro so many years ago, I doubt they will offer me any type of upgrade (it was with my Mac Pro Early 2008). Is there anything else Mac that is worthy considering the two requirements I have above (PIP and Multi-Camera)? Thanks
  5. Also dishwashers. 1 yr delay.
  6. I bought the handful of MOS 6502 from a seller on eBay only to get CPUs which looked very different when received. I wanted one for a picture frame/wall hanging project, and a few just to have. Silly me, I had a primo example of the coveted MOS logo'd 6502 in my possession already. This started life in a 1541 disk drive. When I bought my first PET 4032 in the early 2000s it arrived DOA. Convinced it was the CPU, I swapped it only to find that it was not that at all. The PET was moved into the garage where it hosted pets of its own (a family of mice). I won't ruin the mojo here with a picture of that unless somebody really wants to see it. Otherwise, here is the result of the original 1541 MOS 6502 CPU mounted in an Apple II rev 0 reproduction board which I partially populated to highlight a dozen or so innovations that the original Apple II brought to the [then new] market.
  7. I have two 6502 'systems' working in unison in my '8-Bit Wall of Doom' intro but really it's not cooperative or parallel but rather, a semaphore with one KIM-1 (an Uno) waiting on a signal (SIGWAIT) from another 6502 (a Corsham) system; one counts down and the other counts up in Space-Shuttle-Lauch-Sequence style. Not really that exciting since they aren't exactly in Parallel.
  8. What, you don’t like Steve Punter : )
  9. Be like Steve and donate 1,000s of units to public schools. That will be a good jump start.
  10. PETSCII Robots. The Channel is hosted on Apple2Infinitum https://app.slack.com/client/T1J8S1LGH/C01JKQJBYQN/thread/C01JKQJBYQN-1612744612.106300 Try that link... you may need to be on Apple2Infinitum first. I'm not a Slack expert but used Slack in a MERN Stack bootcamp I attended a few years ago and have been viewing the 'forum' through it. The PETSCII Robots channel started as discussion David and the Apple developers (for the Apple port) but has jumped all over the place including many OT posts, as tends to happen.
  11. Similar story. I joined Facebook for discount codes at FrontPanelExpress and joined Twitter for the Orion mission (the capsule was tweeting as it traversed space... seemed like a good idea at the time as I sat in Florida between watching launch and seeing the telecast of splashdown). My wife is not happy that I never connected with her on FB or LinkedIn for that matter but frankly, I can't be bothered. The development of Petscii Robots suffered an ironic but similar twist... a Facebook group was extremely active and some segment jumped over to Slack for a while. In the end, unless you spend all day every day checking every outlet (some people have time for this), you're going to miss out. I'd rather spend time in what I consider to be the official source. Oh, that and complaining : ) I consider this the X16 home but disappointed that days later, nothing has been posted about Proto #3. Having said this, my experience with Kevin is that he works extremely hard on this and his other projects, and like Stefany from Foenix, does not spend time putting a social media presence together. He has put a few very good video updates but they are few and far between. We all want more and want to see this thing released. Considering the price of prototype boards, I'm starting to get concerned about the cost and considering the time it's been taking to get something viable, the irrational side of me just wants a board with some parts on it that works and I'll manage to wire up a power supply and turn it off when I'm done the old fashioned way. At this point a light switch in a blue plastic Home Depot old work box will do. I don't care much about power management; just want a working unit. Waaaa...
  12. That was the 'per' price for buying two, including shipping; the back out VAT but I may or may not have to pay the Tariff man when it arrives. I'll PM you the deets. Don't want to create a stir before I find out if this place is legit or not. Sometimes if it seems too good to be true... I can stomach losing that much $$ but will not be able to get over the guilt if it ends up scamming the many.
  13. $165 including shipping (ea) again, assuming it shows up. Will just take comfort that it works. One modern power cable, one HDMI. And the joystick has clickey micro switches (improved from the ‘mini’) which I believe can be swapped out for leaf. I spent $200 on just the Commander keyboard from WASD which is of course lovely. This will not be ‘that’ experience but probably better than the high-end keyboard with VICE considering the ways in which tools are integrated as demo’d by *show-and-tell. Will share findings.
  14. I just bought two from the UK at a very good price -or- I’ve been had, and am about to get ripped off when nothing arrives. I was completely unaware that it never shipped to the US. Robin had his review of the CDN model in December of 2019. Of course he had ‘a’ part in its development. The suggestion above is good but I already have enough science projects so hope this is as faithful as it appears.
  15. I have the Mammoth joystick all-in and a pair of C64 Minis but after watching Robin's Show-n-tell on the Maxi, I'm hooked. Anybody have it that does not like it? My 8 bit collection is well represented but at present, the C64 contingent is a pair of SX-64s and only one works well; the other has a crap SID and a memory issue and is sans kbd. Do any thoughts on +'s or -'s on the Maxi? (I checked other threads and see some bits and pieces but not a dedicated topic so apologies if this is already 'someplace'; please direct me)
  16. Kevin posted this on Facebook (to which 66 comments were added; combination of smartest-people-in-the-room and snark); see images which I pasted below: He said: Hey everyone, Prototype #3 PCBs have been ordered! This board incorporates all of the fixes made to the second board, with some circuitry simplification, and the other changes I dicussed in past posts. I had been holding off for awhile as we may yet use a microcontroller for PS/2 Mouse and Keyboard control if using the 6522 doesn't pan out. I had already added an ATTiny84 to control power on/off & reset, so I moved to an ATTINY861 on this board to add enough legs for the PS/2 ports. I then added jumpers so we can select either one for testing. This will be removed from the final board, but I did try to get the layout closer to what I feel the final will look like. Other changes include: I moved from a 50 pin edge connector to a 60 pin! I was not a fan of using a 50 pin port as I was afraid folks might confuse it for an Apple II slot. Likewise, the 62 pin port is the same as an ISA card. Now, little to nothing that makes any sense will fit and I was able to add a few more pins from the CPU to the bus. This PCB is 4-Layer. I did this for a few reasons, but the primary was hoping to keep the noise level IE, RF emissions as low as possible. It now has a proper ground-plane and while the PCB cost does go up a bit in low quantity, it's not actually too bad once you start looking at 100+ PCBs. Took a wild stab at adding some EMI protection on the PS/2 and IEC port. Also added resettable fuses to main PCB to limit current flow.
  17. it's not. That drive is 'toast'. Years ago, there was the famous "Bicycle built for two" song that was downloaded into the 1541 to amaze family and friends. And it was short. Aside from being supremely innovative, freespin must be the master of disk head alignment.
  18. Watched a bit more of the 'live' video. Captured a few things but I'm not (and will not) join Discord so if somebody cares to contradict/correct, please do... case to be aluminum strut with panels not plastic molded so I suppose as a 'kit' it's less expensive to ship and far less expensive to produce than using custom plastics. Some talk of 3d printed for DIYers. Stefany's approach looks to be, throw everything on board then worry about all of the logic/bus/switching in FPGA. Interesting approach as it provides some amount of future proofing and the ability to negotiate relative bus speed differences without leveraging tons of DIPs 27* family or requiring a full board re-issue. Now that I've been thinking about it, I definitely like the emulated (and supplied [example: SID]) approach for many of the sound ICs. The very nice thing about this is that tons of SW was written to support SID and the others and if the instruction set is a superset of 6502, it will ultimately support a more broad catalog and ease of porting. similar to 'David', she mentions her love of the classic monolithic CPU and wanting to limit custom ASICs or FPGA everything; in the conversation she compares it to Apple with chips that do who-knows-what; also, similar to X16, it's PS/2 only and not bothering w/USB. unlike X16, she is going to include a hard disk and maybe even floppy interface in addition to SD. Also, unlike X16, she is going to have a serial port onboard. That will play well with my vintage 9600 baud serial protocol home network. : ) I'm not familiar with the CPU but it looks like a superset of the 6502; One of the collaborators has a few YouTube vids posted and most of the opcodes look familiar. Also, regarding '+1' CPU, her affection for the 68K may bring some 520ST code sooner than later. She cited some ST music SW that may be useful to port and her admiration of the early SGI interface as well. Getting up off the ground in a windowed but primarily text interface is appealing; I remember my days visiting HP (I was doing benchmarking in Palo Alto at the time; early 90s), we had a windowed terminal that was effective and led to a great multi window text based dev environment that allowed copy/paste between text terms. she is not interested in dealing with duty/tax, reselling parts that will only add to the markup, and does not want anybody to try and port Microsoft Windows to the 486/66 variant of the add-on CPU board (LOL to the last bit). Whether or not either of the projects deliver, I think the biggest difference in approach is that David (here) had a vision, spoke to some people, established relationships (some of which he already had), then took a step back. THIS website (and I think a Facebook group) is very organized and is leading to a lot of conversation, a community, and software with boundaries that is reinforcing the likelihood of success; all we need is HW. On the other hand, FOENIX is a 24 x 7, primarily one-person, highly opinionated HW-first effort and much of it is informed by "I'd like it to be able to run this but not that / do this but not necessarily that". And it's much more ambitious, but due to lack of an organized community, is more likely to stay a science project or not be widely adopted (my opinion of course). Because I'm fortunate enough to have some amount of disposable income, I'll be signing up to buy both as soon as it's proven to not be vaporware. If it were kickstarter based, I'd sign up now but the Patreon presence is nowhere, web site a bit of a mess, marketing poor, and considering a planned availability near October, I have a hard time believing just yet.
  19. I must be living under a rock, this is sound chip madness. I don’t have enough patience to sit through the 2+ hrs but can somebody tell me what ROM set is being used for the base and how the memory map is organized (emulating something?) or is it a free-for-all? Is there an active dev community or is this the complete opposite of X16 (no SW, all HW) If it’s a real thing, $500 is not terrible, especially if audio is your bag.
  20. Some pics, in case you forgot what was inside... Sent from my iPhone using Tapatalk
  21. I have a few of those and met Jeri a few times while on the West coast. She is awesome. The game lineup was good, not great but similar to the Mini C64 in that EPYX games seem to be very easily licensable or maybe in the public domain by now? Jumpman and JMJr. was always fun to play but more quirky than I remembered. Pretty sure it was just the game itself rather than the emulation. But how did she get that platform on a chip well ahead of even VICE being any good and well before FPGA was affordable, or was it back then? I think I took it apart and there was epoxy on it? Maybe I'm confusing products. Anybody know?
  22. Is ‘resident’ assembler different from the MAE aka Macro Assembler that Commodore sold at the time? Thats what I grew up on and it worked well. Eventually a ‘local’ gave me a copy of the assembler that he wrote (!!!). At the time I was like WTF, who the hell (my age of 19) could actually write an assembler, but he did. He was famous. Having been spoiled by Borland Turbo* products since the late 80s, its hard to believe that we assembled multi-pass from Floppy to Floppy in those days. It was only two clicks better than writing (punching) and reading from Digital PDP paper tape but at the time it felt like rocket science.
  23. None of that. Only asking if it would be easy enough to implement a task switch where the current 'task' / program is pushed into the background (and stops executing) and a new workspace exists to start another task of say, the next 128K bank. Copy/paste between the two would be nice. That's all.
  24. It's unlikely that an X16 will be called upon to have multiple users connected over serial port connected terminals in manufacturing, one in accounting, and a third in engineering; so multi-session (verses multi-tasking versus multi-user) is what is needed; similar to when Apple first supported Multifinder on OS7.1. From Wikipedia: "Switcher works by designating a number of fixed slots in memory into which applications could be loaded. The user can then switch between these applications by clicking a small button on the top of the menu bar. The current application horizontally slides out of view, and the next one slides in. Though awkward, this approach does fit well with the existing system's memory management scheme, and applications need no special programming to work with Switcher." Otherwise, all of that context switching just adds overhead and complexity with no MMU to support it. Instead, session-switch to different sets of blocks of memory only when the user switches from editor to compiler to whatever. Will that fit the bill?
