  1. Some of my favorites: 6502 Assembly Language Programming by Lance A Leventhal Inside the Commodore 64 by Milton Bathurst Allied's Electronics Data Handbook (2nd printing 1956) The C Programming Language by K&R (first edition) Digital Computer Electronics by Paul Malvino Compute's First Book of Machine Language Mapping the Commodore 64
  2. Oh yes. Understood. I was proposing kind individuals buy a full system state-side, pull and pack the board and ship to somebody in need (in UK or other Europe) as 'parts' or 'components'. Then at a later date, attach a handle to the case, make believe it's a stylish European briefcase, and bring it onboard as carry-on during next business trip to deliver the rest.
  3. I'm going to have to break-out my Apple Newton MessagePad from 1993. I don't have any other devices with Gopher clients : (
  4. I've dealt with modular analog synth makers in Germany, Portugal, and the UK for many years and if you want 'it' that bad, you have to pay the piper (shippers, settling Vat issues and tariffs not to mention PayPal and currency conversion costs). Every party along the way uplifts and often you spend +25% or more just to acquire a product. BUT, somebody will probably unofficially work out a way to ship a partial/kit board as a favor without the fancy case, etc. I wouldn't call it a deliberate attempt to skirt tax authorities, just a friend helping out a friend on a one or two-off basis. AT cases can be had locally for cheap, then on the next business trip to London (as an example), drag it onto the plane as a fancy piece of futuristic carry-on luggage (it will have detachable wheels and a strap?)
  5. Somewhere in a closet around here I have a notebook sized Epson LCD screen'd machine with a full mechanical keyboard (and I think a thermal printout) but it's probably not worth digging out because I've seen the two extremes already posted in this thread. Amstrad being one. But the other... oh my... I remember two things about the Coleco Adam; a good friend had one. 1. It played Donkey Kong 2. It had a Daisy Wheel printer. The winner (loser) has to be the company that invested so much $$, engineering, and licensing into a full end-to-end line of support (as demonstrated by the collector I that video) only to fail so miserably. I'm both shocked and amazed to see the other 128 things that Coleco Adam had and did. Thank you for posting that and bringing back the memories.
  6. This thread has been around for a while but I just now read it end-to-end. I had an account on bnl.gov (Brookhaven National Lab) hen I was. teenager (a friend of a friend's Dad was a physicist on site and gave me a Unix account). I was 16, he was crazy to have done it. I'd get fired at my current company for 1/10th of that act. One of my favorite motd's was "Beware of programmers with screwdrivers". I used this as part of my signature when I was on Panix in NYC in the 90s. It directly applies to David, I think. Once you get to even 100 subscribers, one of them is going to object to something that you say or do. Adrian from '*basement' often says "if you didn't like this, you know what to do..." and many others say "I know, I know, before I get dozens of commenters say xy-zed...". My view (I'm old enough to live in an active-adult community so...) is that David is an uber-talented SW developer and has a passion for history, curating 8-bit everything, developing content... but (here it comes), hardware is not his thing. I've seen him solder, use a dremel, etc. HW is just not his thing and I'm literally laughing as I type this. But he gives so much to the community that he's bound to have a misstep. With full disclosure, I did not watch the video in question or the response (I don't have that much time left so have to pick/choose how I spend my time). : )
  7. I am a Mac and, yes via Vice so your explanation makes sense, thank you. I chose Brown switches just based on what I read. Pretty happy, I suppose. My only experience with Cherry was the set of Blacks I bought while building up a TexElec Pet keyboard for which I used flat, china-made crap [flat] keycaps. It's about as horrible as the four or five Mac devices that I have with keyboard efforts that are downright embarrassing. At some point, laptop makers striving for thinness and style-istas took over the world. $210 is too much for this keyboard but having the Petscii keys represented make it worth it. Thank you for the reply.
  8. I'm have a issue with mine... does anybody with one of these have an intermittent issue inadvertantly getting the Petscii '+' graphic symbol (normally on the tic key of this keyboard normally or on the original pet squad bracket key) when typing quickly within VICE x64 on this keyboard? Also, while I have you, in what circumstances does the 2nd LED (non-caps lock) illuminate. Is there a magic scroll lock combination? I would have thought that the 40/80 Display key, since it's non-locking, would be this key but on mine, it is not. Finally curiosity for Tom, which Cherry switches did you choose and how do you like them? Thanks.
  9. @TomXP411 what version of Ultrix are you running or are you a VMS?
  10. This reasonably sized lcd has 'all' the inputs and a pretty good review by Chris Torrence (Apple ][ guy). Might be suitable for the "> 10" but not huge" use case. See here: Here is the link to ReActive Micro: https://www.reactivemicro.com/product/reactivemicro-12-lcd-display/
  11. In one video the person running the demo changed the cursor/text color but the poke for background color immediately was forced back to black. Probably a ROM revision to keep the would-be student from ending up with a combination of text and background that doesn't play well on green monochrome. Or protection from reverse burn-in. I don't see an internal speaker on any pictures and don't see wiring for an external speaker (so it would either require the video/audio I/O DIN; five pin midi type or nothing). I did see Space Taxi running in a pic and the color showed up as reasonable grey (green) scale, so something resembling color
  12. Check out this eBay listing (or just the single pic below) of a 4064. Commodore dared to pair a C64 with a monochrome screen in PET packaging for non-U.S. markets. Maybe there are many of these in the wild in the same way that there are C16s all over Hungary or maybe I'm just not paying attention and am the last to know. On one hand this is impressive; on the other, crazy. Does anybody know, did they strip the C64 of the SID and VIC-II or is it just the RF Modulator that is missing?
  13. A few thought on OS vs. living from a Basic command interpreter: If a modern-ish GEOS style can be optionally banked in/enabled for those that really want that [not me], than both camps will be satisfied (one that wants a contiguous memory map without banking business and one that is willing to manage RAM and forfeit some always in ROM code/OS). I'm nowhere near well-read/informed when it comes to how MMU type functions will manage the banking of the memory north of the 64K boundary; Maybe the team here has already worked that out or maybe it's roll your own e.g. plug a number into a single memory location to determine which bank of 8 or 16k overlay a portion of the contiguous 'main' memory. But as a recent Apple II convert, I'm struck by the difference of environments, capabilities, product ecosystem, longevity, and market value of Apple products. Built in monitor that Commodore for some reason dropped after the PET is awesome Zero disk capabilities without booting into "DOS" is nuts. Makes you really respect the afterthought of a command channel to IEC serial devices Applesoft Basic with plenty of extensions for graphics and what not, mixed mode screens, etc. but nothing other than sluggish bit mapped graphics with PET style 'sound' and fake color = madness But on the other hand, I bought an Apple II+ with a language card, drive, Disk ][ drive, Epson printer interface for less than I can buy a C64 with a broken keyboard. Since picked up an 80 col card and a SuperSerial adapter. My Commodore 128 (mounted to the wall in my STEM Lab as me and our 11 yr old call it) had sprite editor and a bunch of other tricks that I never even bothered to use. So in short, do include the xtra niceties of some extended Basic commands and disk utilities, a ML monitor and an image, char set, and tile editor if that could be omnipresent and allow a rom banking (probably too late) for fancIER GEOS. Would love to see the MVP, EPICs, and jump in on your Sprint planning PBR and demo sessions; because scope creep coming from guys like me must be fun, considering : ) Everything else is awesome. Looks like the machine is ticking all the boxes ... but please hurry : )
  14. Odd that whomever wrote the code/doc chose to buck the convention set by Commodore code and go with printable ASCII characters only to reach into the awkward range of special symbols; '?' is an especially bizarre choice (my coloured opinion, only). Would a 'DOS"P"+CHR( {channel} + 48) + CHR$ ( {low byte} ) + CHR$ ( {high byte} ) + CHR$ ( {higher-order-byte} ) + CHR$ ( {highest-order-byte} ) work? Interesting that as high as 32 bits can be expressed (4GB max file seek is potentially possible. Maybe dump the entire Encyclopedia Brittanica into a single file and allow an 8 bit Commander app to provide a browse/search, just as the early 90s IBM PC CD-ROM titles did. That was amazing !!
  15. VICE implemented it just fine... why not just reuse or is there a thorny licensing issue that does not seem to bother the VICE crowd but is an issue here? (made more challenging still because nobody knows what it is : ) Did the x64 developers actually start with nil and build up the entire legacy Commodore drive DOS but skip REL and USR portion of the code? Jim Butterfield (RIP) would be most disappointed. My BBS User and Message manager can be rewritten but the catalog of TPUG PET Recipe and VHS cataloging programs have now died their 2nd death : (
