My Custom HP Logic Analyzer 16700A Cart
So after looking at the high priced real HP logic analyzer cart that didn’t look that great to me, I decided to build my own incorporating a ton of features that just really makes my life easier. This is optimized...
My new i7-4790k Desktop build
I needed some more horsepower for my FPGA compiles, and because it’s been so long since my last PC build, I decided to take advantage of some free time I had, and build a new machine. This machine is a quad-core...
Memory controllers in FPGAs are the bane of my existence, help needed
I want to put together a softcore 68K computer system, just something simple. I’ve purchased, but not yet received, the Terasic Cyclone V GX Starter Kit, an Altera FPGA eval board. It looks pretty sweet and...
$28 Gonbes GBS8200 Scandoubler for use with Commodore Amiga
While I probably would have preferred to order an Indivision ECS scan doubler, a really nice alternative is a Gonbes GBS8200 video converter off of ebay. I had bought version 2.0 sometime in 2010 or 2011, and could not...
Kickstarter: Commodore, The Amiga Years Book
I just wanted to mention that I’m a backer on this kickstarter, and I just wanted to get the word out. I’ve read On the Edge: the Spectacular Rise and Fall of Commodore and I’d love to read this...
DIY 115 watt flexible LED Task Lamp
So I wanted a very bright flexible LED task Lamp that didn’t break the budget. I had a few feet of 7020 LED strip lighting left over from my undershelf LED lights, so I decided to put those to the task...
migrated website to a new host
Over the last week, I migrated this blog to a new hosting provider. GoDaddy was such a pig and the site just ran like molasses when hosted by them. I couldn’t be happier with the switch that I’ve made, but I...
Reading Amiga Kickstart ROMs with a TL866A reader
I recently bought a TL866A from ebay with a bunch of adapters for a little under $100 shipped. Seems like a decent programmer except for the fact that it doesn’t support the 27C200/27C400 mask ROMs that hold...
Update to Rigol CSV to OLS file conversion post
A couple years ago I posted some information on how to convert a Rigol CSV to an OLS File. I recently got a request for some more information. So let’s look at the two files First twenty lines of the Rigol CSV...
Commodore Amiga Floppy Analyzer
So I’ve toyed with the idea for quite some time about having a tool that was a little more “data” centric for analyzing floppy data. The Amiga Floppy Project Nostalgia client(which was the main Java...
New 3M, now Desco SCS, antistatic mats arrived today
Before today, I was using a “field anti-static mat” on my HP Logic Analyzer cart. This was the cart that I built from scratch, and I think it did the trick for the most part. But the more and more I started...
Trying to use mini-box picoPSU-120 to power Amiga but -12v rail is out of ATX compliance
So I purchased a mini-box picoPSU-120 kit which is in essence a very very small power supply that provides multiple regulated voltages. I want to power my Commodore Amiga 500 with the tiny power supply but there’s...
Powering the Commodore Amiga 500 with the Rigol DP832 supply
So thanks to Mike/amigamech for still having brand new stock of 5-pin A500 power connectors that he could ship quickly. I used information from for the various pinouts. I have ordered a picopsu really small power supply...
