Ended up destroying the v1 prototype, too many damn wires
This version is much better, much cleaner.
I also ordered some new wires that I hope will clean up the latch <—–>memory connections and amiga connector (CNX) to the protoboard.
Things are coming along……..
Finished wiring of the prototype, hooked it up
So I finished cabling up the solderless breadboard, and after checking connections, and checking pwr and gnd, I plugged it into the amiga. The amiga boots, which is a good sign, but then it never recognizes the memory. I’m not … Continue reading
first night wiring progress
Now I remember why I like FPGAs so much, no freakin’ wiring!@!#
Here’s a start to what the monster looks like. I think I’ll like the PCB form factor a little better. 
I thought a little bit about how I lay this out, but I didn’t come to any great solution. Almost seems like the traveling salesman problem!
ISSI memory chip mounted
So I can’t believe how freakin’ tiny those pins are coming off the memory chip. The pads on the surfboard were huge by comparison. I actually thought there was a manufacturing defect on the memory chip and they forgot to include the pins or something.
I am totally lacking any type of magnification…..I’m gonna place a few orders and get some stuff in here for the future. I’ve been looking for a good high quality 10x loupe and a lighted magnifier for a long time. Most of what I see out there is total crap.
Let the fun begin!@#!@#
Everything has arrived! I think the first order of business is soldering this darn memory chip…. Not sure how hard this is going to be, but I’m going to give it a shot!@#
Parts ordered for the A501 replacement card
I placed an order yesterday for some prototyping parts to get this project off the ground.
Some of the key parts are:
Converting Rigol DS1102D Logic Analyzer .csv files to OLS data file format using Linux
How to convert .csv files exported from a Rigol DS1102D MSO to OLS data file format.
So I own a Rigol DS1102D 100mhz MSO which has two-channels of analog and 16 channels of logic analysis through the active logic head LH1116.
Amiga 500 A501 RAS/CAS dynamic ram timing
So I found myself looking at the dynamic ram timing with a logic analyzer attached to an Amiga 500.
I’m still learning all of this stuff, and after about 45 minutes, I gave up thinking that I was either too tired, or too dumb to catch on to this stuff.
