Under the hood of a 8088 XT PC desktop computer

A friend of mine was moving and no longer had room for this treasure. I generally only like to collect older computers in particular I’m fond of S-100 equipment or CDP1802 based items. This was too much to pass up though. On the top you’ll see the 5-1/4″ floppy to the left, followed by the (I believe to be) 20MB MFM hard drive which is tiny (in physical size, typical for memory capacity) for it’s day… the DIP memory to the right, I’m fairly certain by memory part numbers I’m looking at 640kB of memory. .. then in the 8 bit ISA slots on the bottom you have the MFM hard drive controller card on the left, then the floppy… a serial port adapter (25 Pin D-SUB) and finally 9 pin monochrome video adapter with a built in parallel port. Unfortunately the monitor he gave me has a 15 pin D-SUB which I thought they started at VGA but perhaps it’s an EGA monitor–it’s poorly marked. At least it came with the 5 pin DIN keyboard. As soon as a built an adapter for the video I’ll give it a chance at a boot-up. I’m considering a trip down to Alphatronics this weekend to see if they have an 8087 co-processor since they weren’t typically installed and that seems to be the only stuff Alphatronics has any more (old chips everyone’s long moved past, try getting an OP Amp there released in the last 5 years). After my visit there I’ll hit up  RE-PC in Tukwila; perhaps they will have some spare cards and extra memory if I’m really lucky. Another score for my personal museum collection.

3 Axis CNC Controller TB6560

So I bought this controller on eBay a few weeks ago. I honestly haven’t done anything with it as I’ve been a little focused on the mechanicals. It seems a little in the cheesy side as the labeling an keypad aren’t complete secure. I’ll provide an update once I power it up. I put the USB to parallel port adapter near it for a size reference. I guess we will see if this was a $130 mistake?

A lazy weekend

Well I should have been up on Bandera Mountain this weekend; I didn’t make it. We ended up at IKEA and so I had a long weekend of building bookshelves. We have a real library now, no 30$ cheap-o shelves, real wood, glass doors.. the works. This is definitely bucket list fodder. I have 20 or 30 boxes of books I can now bring back from my farm in South Dakota. Right now it’s looking a little paltry with only  200 books or so. I’ll drop a photo once it’s a little more populated. I realize IKEA is often synonymous with cheap garbage and certainly they have a lot of $20 desks which I would consider disposable. I think they’ve made a real effort to also provide some quality materials.

While sitting down reading Brave New World (un-recommended by family), I realized I really have a lot of books I need to get to. Few things really ping my mortality like the potential disappointment of not getting to the bulk of the classics.

So Bandera Mountain; a lot of snow, hopefully not a lot of avalanche danger… I’ll see you next weekend.

Other things I need to get to: Seattle Roboticis Society Meeting (Hopefully I’ll see you soon). Seattle Retro-Computing Society… who could resist this?

Good Riddance GoDaddy!

I've been so upset over GoDaddy's horrible support. I moved my account to a company called "A Small Orange".. what an amazing difference. I moved all my domains… armageddonacres.com, iradan.com/, iloveyoumelissa.com, douviercards.com (Melissa's), and others… I was experiencing 10 second load times, if it loaded. Having to attempt logons multiple times, page timeouts.. you name it.

I'll let them host my domains. I like their interface but they have to have the worst hosting service I've ever seen… so I pay $1.01 more a month for bliss. Feel free to ask if you have any questions.

Lake Serene Attempt

Well conditions weren’t great this hike. We crossed one snow field that was “iffy” at best and got halted where three other hikers on there way got stopped. This avalanche waiting to happen wasn’t going to get blazed without roping up and we didn’t bring that gear with us. 19,500 ft of elevation gain so far this year… Probably would have hit 20k if we had chanced the crossing… And did some route finding…

The last field to lake serene was an avalanche waiting to happen, we turned back.

Winter Hiking

It’s really tempting to sleep in tomorrow morning. A cold rainy.. and up on the lake snowy morning awaits me. The price you pay to thin the herd I suppose. I’m looking forward to visiting Lake Serene and perhaps we’ll bag a peak if we have the energy for another hour and a half..

My electronics projects have really taken a stand still. I’ve gotten just enough everything I need in to create a CNC mill to mill some PCBs but life has been really needy! Hopefully I’ll build that shortly.

Dear Future Me: .223 ammo is $900/1000rounds. I hope I made the right choice to pass for the day it’s back at a sane value…

2013 Hiking Progress

With this morning’s ascent up Squak Mountain I’ve reached 33% of my mileage goal for the year and we’re 25% through the year. Elevation and number of hikes are flying by in comparison… Guess my goals were lopsided. I shared the trail with runners and unleashed dogs in masses. It was only about 1,600 ft of elevation gain but I wanted to ease myself back in after a few week break. Ill be paying for my jog down tomorrow I imagine… Old knees! I think the west peak was the likely point I should’ve headed for but I could t resist the chimney and keeping it to a loop. Too bad I missed the old mill. I love checking out old buildings… Who doesn’t though?

Parts Storage

My wife found these photo holders which convert into great parts storage. This is half my parts minus boxes with the big stuff..

I need to buy some more of these soon. I love these for parts storage. I’ve gotten more since but I think I’ll definitely need more when I bring back more parts from South Dakota (my house back in Sturgis has a lot of my storage yet). These are actually 4×6 photo storage cases bought at Hobby Lobby for some where in the neighborhood of 30-40$. It took me forever to separate my 74 series logic, 4000 series and linear parts.

 

Hello World?

Ugh, Hello World. Really? Sometimes those eleven characters* can drive you insane. I was debating buying a Suunto altimeter watch; They are painfully expensive for the number lackluster reviews. God they are gorgeous though huh?! I decided that I’ll just have to pass and build my own altimeter. I’d also like a barometer with that fancy alert system… so no problem right? Sparkfun barometer board.. PIC16F1590 breakout board and some random 16×2 LCD I pulled out of my box of goodies. Hello World is kicking my ass for some reason.. granted I’m only 4 hours into it.
