Replica 1Ten #10 in da house!

Postby jac_goudsmit » Feb Sat 01, 2014 2:33 am

Hi guys,

I received my Replica 1Ten in the mail a week ago, and though my fingers have been itching to put it together and play around with it, I didn't have time until today. Just like with the MicroKim, I had my stepson do most of the soldering. He's a Computer Science student, and a beginner at soldering, but the kit worked the first time with almost no help from me.

^ I put in all the resistors because I don't need to look up all the color codes. Then he soldered them in.

^ The sockets were next.

^ Long story short: after a short time, it was done. The time stamps are far apart because we took a dinner break. It took us about 2 hours total.

^ I made a small modification: I put some female headers on the circuit board and plugged the Sparkfun USB interface into it. That way I can fix it if something is wrong, or use the USB interface for something else (the pins are breadboard compatible)

^ Another modification was that I decided not to solder the card edge connector onto the board. I figured, that way if I want to connect some electronics I can solder it to the connector and plug it into the side of the board (as I did here) instead of buying a new .156" pitch connector (they aren't used much anymore, so I don't know how hard they would be to find) or creating my own PCB.

^ I have a small LCD TV but it's extremely picky when it comes to incoming NTSC signals: the CVBS input has never really worked reliably and when I use a modulator, it sometimes almost works but apparently not today. Fortunately I could borrow a CRT TV which of course had no trouble at all. Don't throw all your CRT's away, folks! The random characters were the first thing we saw when we turned it on. Looks like garbage but this actually means SUCCESS! :-)

^ Of course the first Basic program is Hello World

We tried to download some other Basic programs from the CD-ROM but were unsuccessful: every once in a while, a character doesn't transfer correctly. It's probably a matter of tweaking the settings on TeraTerm (extra delay on the characters) or something.

^ My stepson recently had a class on x86 Assembly and was most excited when we found out that the Replica 1Ten has Krusader on board: an interactive assembler/disassembler/debugger for the 6502. He said he could have stayed until two in the morning but unfortunately he had other (family) obligations. Maybe later!

Just like when we made the MicroKim, we had lots of fun putting it together. If you get both this kit and the MicroKim, I recommend starting with this one because the component count is much lower.

Thanks for watching, and thanks Vince for this fine piece of early Apple nostalgia! I'm not a fan of Apple as a company at all, but I like the early systems that were designed by the Great and Powerful Woz, so an Apple 1 Replica has been on my wish list for a while.
