    Possible, I didn't count whatever precedes $033C. For disk users it is free memory, for tape users one should be aware that your machine code routine may get overwritten if you stored it at the...

    Besides the 196 bytes of cassette buffer at $033C - $03FF, you have 89 bytes in the area $02A7 - $02FF that are free to use even if you're using the tape recorder. It may seem like very small amounts...

    The N8VEM wiki has been been made private and is about to get migrated to another site, this might be why you see a login prompt when you try to access the videos.

    As far as I know, the N8 board...

    I've got the TL866CS but only used it handful times in the past two years. I mostly use it to program those GAL chips my GQ-4X doesn't support, but it is a good thing knowing it can test logic ICs...

    I would assume the selected design was at least $2 cheaper to manufacture then using e.g. a Z80. You know the importance of cutting costs even on high profile, expensive gear.

    A few systems, mainly French, offered analog RGB (although the palette would just be 8 colours) in 1984-85 so the tech was there. However I agree with all the other posters that it would have...

    To clarify, the DIN socket on the C128 is used for 40 column video in C128 and C64 modes (or CP/M I suppose, if you want to run it with 40 columns). That socket carries composite video, luminance and...

    If you've got an EPROM programmer and a suitable 2716 chip for the Editor ROM, it wouldn't be quite as difficult to program the chip, carefully lift the original ROM and plop in the EPROM into the...

    Thanks again. I'm looking for the easiest available option to get sound out of a non-CRTC PET, not connect it to my Hi-Fi equipment, so I'll settle with the cookbook example with an extra resistor. I...

    What strikes me is how unusual to see even homemade mods involving separating the keyboard from the motherboard, making a "SK" model. The only one I can recall seeing was a VIC-20 in parts, once...

    There was a company in Australia who made/sold own casings that resembled the C64C case, but was not identical. There may have been other sources for cases as well.

    Although on the outside the...

    Thanks for the clarification. I'll probably go with the Cookbook variant then.

    So what kind of signal do I get if I just add a resistor of say 500K as described in the PET FAQ and in title screens...

    Necroing this thread, regarding the sound option. I have seen the classic variant being connecting a 50-500K resistor between CB2 and the amplifier. What kind of signal do I get from doing this, will...

    Wow! You put quite an effort there! Is it interactive like a real game, or just simulating input as it goes, like a demo? It gives the old IMSAI a run for its money.

    Hm, didn't you just mention the TV has analog RF input? I would plug in the cable from the MC-10 into the antenna input directly, without going through any other boxes you might have. Actually if the...

    Would any B&W TV sync to the 20 kHz frequency though, or is a change of ROM anyway planned?

    Well, a number of years ago I tried to build one of those diagrams. From a 40 column board, I got a somewhat readable display on a 1084, although the display would not sync vertically. From a 80...

    I think that CGA to SCART layout by "Unknown author" exists in a few variations. Worth noticing is that standard CGA does not have a 5V nor a 9V output to drive your MOSFET (?) or 74 series chip, so...

    If I understand correctly, the video runs at different frequencies so the monitor used with said adapter would need to sync to any frequency. But I think there are options, at least finding a...

    With that definition, I am not surprised that 90% of those who have voted claim to be active collectors. To only rely on what you bought 20, 30, 40 years ago would limit your choices a lot.

    I've got the French licensed model, the Matra Alice and it takes 10VDC 1.3A but I realize it may have been reengineered since it also outputs RGB out, which the MC-10 doesn't.

    However there is a...

    Out of those, I believe only the 8280 made it into the wild. There were two 8280's sold on eBay last month, at 667 and 700 from the same seller. Neither drive was in fully working condition.

    So...

    It can also be noted that some PET keyboards have the same internal plungers as Atari 1200XL, possibly other Atari models too. All of these came from Mitsumi if I'm correct, so it doesn't strictly...
