    d have hated to do by hand with graph paper - like rotating
    all the Pacman images. On the other hand, debugging can be a big pain,
    unless there is some source level debugger that single-steps through your original source code that I'm unaware of. I'm not sure that we really have
    it that much easier now than then in that respect.

    Q. If you could code the VIC in the 80s, what would you have done (maybe a career change)?

    A. Yes, that was the dream - to make a career of programming 8-bits.
    Honestly though, I wonder, "If I had been the age I am now when the VIC20
    first came out, would I have paid any attention to it?" I say that because
    I pay very little attention to the "popular" technology that is out there
    right now, like the iPhone, for example. I may have written the VIC20 off
    as some fad of "the young" while I was busy with my IBM and COBOL
    programming.

    Q. If you could go back in time and change one thing about the VIC, what
    would you change and why?

    A. Wow, another killer question! Hmm... I remember the day I unpacked my VIC, lamenting how low the screen resolution was compared to the Apple II
    and Atari. However, there was no way I could have afforded those. That is
    the obvious complaint of a 12-year-old in 1982, but looking with the eyes
    of an adult in 1982, what would I have changed? Hmm... I don't think I
    would have changed a single thing. Anything added would have increased the cost - and that was the whole point back then. Maybe they should have
    included the Programmers Reference Manual as part of the base
    documentation. Commodore had great documentation.

    INTERVIEW WITH THE CREATOR OF THE
    C64P
    By Commodore Free
    *************************************

    The Future was 8bit is a website that has grown from a fanatical Commodore owner's own need for toys into a one-stop shop for SD2IEC, C64p, and other peripherals. "My own long-held desire for a C64p is the only reason my
    line of SD2IECs exist. Something like three or four years ago I built an SD2IEC to try with a C64DTV. The left-over SD2IECs ended up on eBay...
    and the rest is history."

    First, what is the C64p? Well, it is a C64DTV-based laptop measuring 21×14
    cm. which Nic has customized. The laptop starts as a new product; then
    all the insides are removed - even the the TFT screen is replaced. The
    only remaining parts are the battery and chassis, which are then populated
    with an SD2IEC, keyboard interface, three custom PCBs, 7? TFT, 1530 joystick-mode mouse, and an ASUS unit which replaces the charger/PSU. Add
    a dash of custom firmware flashed onto the DTV chip (which lets you choose kernels). JiffyDOS anyone?

    NOTES ABOUT THE KEYBOARD NG

    This means a lot to people who know about the DTV. If you connect a DTV to
    a real keyboard the biggest issue is the lack of F7, among other oddities
    (not good if you want to play KikStart!), but the keyboard twister fixes
    this. NG - Next Generation gives extra functions. There is a hack on the
    NG ROM (the standard ROM is for German keyboards) so it runs in US mode.
    The NG ROM, with a simple add-on diode, gives a user the ability to "CTRL-ALT-DEL", which resets the DTV. No need for power-off/power-on.

    Q. Will you please introduce yourself to our Commodore Free readers?

    A. Hi Commodore Free readers! I'm Nic from Dorset in the UK. I've had Commodore computers for (I hate to say) 31 years, and still use one every
    day!

    - - - - - - - - - -

    Q. How did you become involved with Commodore and computing in general?

    A. Christmas '82 or '83... I found a VIC20 under my tree. A few years
    later I managed to get my Dad to buy me a C128... a few years later I
    bought myself an Amiga 4000. These days, of course, I work in IT - Yay me!

    - - - - - - - - - -

    Q. The C64p, although expensive, is quite an elegant-looking device. How
    long does it take to make the unit?

    A. Well, first - it's expensive because it costs an eye-watering amount to build. I never really thought I'd sell any. After all, I really only
    built it because I wanted one, but the word got out, so I made a few
    extras. It's difficult to guess how long one unit takes to build. It took
    me about 3 years to get them to where they are now, but if I had to guess,
    I'd say 20-30 hours each.

    - - - - - - - - - -

    Q. Are these items made to order - or are they in-stock?

    A. All of the units sold so far were sold from stock. All of the
    components are in-stock, so I don't have to go fishing for DTVs if I want
    to make more.

    - - - - - - - - - -

    Q. I see you have JiffyDOS. Is this licensed? Some forums have suggested this is not the case. Do you think JiffyDOS was an important addition to
    the device, and does it actually speed up loading from the SD card? Or is
    it more for the convenience of extra commands and features?

    A. I don't really follow too many forums, and I really don't get the
    chance to sit in front of my PC with nothing to do! Anyhow, yes -
    technically it's not licensed, but it's not the same JiffyDOS you'd find
    inside a real C64. DTV-JiffyDOS is a hybrid that is easily available for download from the internet. JiffyDOS, just like on a real C64, transforms loading times.

    - - - - - - - - - -

    Q. Talking about forums - have you had any negative comments about the
    unit, and do you have any comments you would like to share back to readers?
    (no swearing, please)

    A. Urm, I have read interesting comments like, "I'd pay no more than £80
    for one" or, "It's a DTV, so it's not 100% compatible." Makes me laugh, as you've only got to use one for 10 minutes to know it's something special.
    I've loaned a couple of demo units out and the feedback was amazing. It
    seems most people`s idea of the DTV doesn't do it justice. Yes, some
    functions are slightly non-standard, but overall, once you turn one on, you don't want to turn it off. The people at CiA ( awesome.c ommodore.me/articles/kitty/commodore- c64p-review/ ) gave me some wonderful feedback. Originally (before they used one) they thought something like
    this could retail for £100-150, but after they touched one they realised
    how cool these things are and how much has gone into making them. They
    agreed that you'd never get anything like this for 100quid.

    They really do look "shop bought" and not knocked together. Everything
    inside the C64p has been built with longevity in mind. Calculators were
    used in the making of these units! To give you an idea - the original
    donor laptop's charging circuit could only be described as dangerous; I
    tested seven original chargers - and I kid you not - only two worked after
    24 hours, and four of them went "pop" with sparks jumping out of the nasty plastic so-called CE-marked PSUs. My charge circuit was designed by a
    friend that has designed charge controllers for Nokia/Motorola and
    Panasonic.

    Q. I find it interesting that people spend so much work developing units
