After many months, my Kaypro 2 is finally up and running! Weighing in at around 30 lbs, with a 4 Mhz Z-80 processor, 64kb of RAM, (upgraded!) dual 360kb floppy drives, and the rock-solid CP/M 2.2 operating system, this box is a lean, mean computing machine. NYCR-BBS, anyone?
While we at NYC Resistor pride ourselves on hacking the latest technology, we also have a passion for understanding that which came before – and the history on which our beloved technology is built. You need to know where you came from, as it were.
My good friend William Pauluh of Hartford, CT is an avid vintage audio restoration hobbyist. Bill takes care to replace worn passives with appropriate replacements, and salvages as much of the original hardware as possible. Then he takes the time to refurbish the exterior and bring the gear to an almost-new look. The audio quality of these vintage pieces must be heard to believe. While the mainstream world is running headlong into compressed, poorly quantized audio – these relics from last century produce mellow, quality tones from primitive analog hardware. With the right patience and expertise, you too can grab an eBay relic and turn it into something new and wondrous for your audio pleasure.
“I’ve attached some photos showing the amp after I replaced capacitors and a few resistors, testing the unit, the amp & speakers in the cabinet, and the final assembly. I didn’t take any photos of the changer during my standard procedure of cleaning/lubing ( I really should, but my hands get so greasy/oily – I’m constantly washing them).
Pilot was a quality manufacturer in the early days (1950′s) of HI FI (along with Marantz, MacIntosh, Fisher, H.H. Scott, and Harmon Kardon).
Garrard was a quality manufacturer of turntables/record changers (based in England). Japanese price cutting in the 1970′s did them in.
This unit has the original Telefunken 12AX7′s (super low noise) and they test out very strong emission – plenty of life left!
I also received the original sales receipt for this Pilot HI FI (model PT-1015). It was purchased from a dealer in Canton, Ohio on 2/18/58 for the price of $169.50 + 5.09 tax for a total of $174.59 (adjusted for inflation in 2008 dollars, it’s around $1000.00).
I read on some link that Buddy Holly’s producer, Norman Petty, purchased 3 of these units back then (I beleive two were with the black cabinet and one in tan). I wonder if one of those went to Buddy Holly?
Interesting trivia to ponder.

Most kids wanted to be something like a fireman or an astronaut when they were growing up.


Me? I wanted to write music for videogames. Some of my favorite pieces of music came from my Commodore64 and Nintendo, classics that I still whistle whenever I find myself in an empty, echoey space.
Think about some of your early videogame experiences. How many themes can you remember? The classics are all accompanied by tunes that we remember to this day. Pacman. Zelda. Mario. Brilliant works defined as much by the restrictions of the “instrument” as by the imagination of their composer.
Well, life often takes you in different directions from your childhood dreams, but I’m lucky enough to get to play at mine as an adult. There’s a whole scene dedicated to writing music for these platforms, and I’ve been dying to dive in, but didn’t really know where to begin.
Luckily, GameBoy Genius over at 8bit collective has put together a great how-to for getting started with gameboy music, complete with a gameboy emulator and awesome tracking software for the gameboy itself. Here’s a sample of what you can create with it(mp3). The gameboy’s limitations gave it a sound very similar to the C64, which also holds a special place in my heart. There’s apparently a “getting started” guide for C64 music as well, guess what I’ll be checking out next?
