Yeah, Athlon covers a lot of ground. My "modern" machine still uses an Athlon X4.

Yes, Chuck it is covered but it takes a little while to go from ones thinking of how it works to how it actually works. I was impressed the first...

SunView - that brings back memories! Do you still have stock on your NVRAM kits? I could use one or six...

When I was in high school, the electronics shop got in donations of equipment from time to time. At one point, we had both a 1000TL and 1000TL/2. I...

These pop up on eBay once in a while.

Any other significant differences besides the fastest speed?

The IIe card can run at just under 2MHz, so it's not as fast as the IIc plus.

Not relating to the chassis, but today I just won this: ...

Love those stud-mount diodes! If you're interested in prophylactic measures before powering things, check the electrolytic capacitors; remove the...

T1000s are still common. On eBay but also on Craigslist/OfferUp/LetGo and so on. Prices are all over the place. Like with most of this stuff.

I have that mobo up and running. You need to do a search for the legacy apps, both CPU and GPU. It might take me a while to dig them out of where...

I was able to take a quick pic of the card cage/power supply of the MCM/70. The card cage is located in the back thick part of the wedge. The black...

I have two TLs, one TL/2, but no TL/3. I also bought all of mine a year or two ago when they were still in the $50 range, or $75+ with free...

Congratulations. ODT on the KDJ11A requires 22bit addresses…even in 18bit backplanes. I just use 77777xxxx, as it drops any excess leading...

I thought all of this was covered in the Altair 8800 documentation. I seem to recall that it is, at any rate. On the topic of front panel...

How is this vintage? Just saying. I use an SD-to-CF adapter on an IDE interface. Inexpensive and pretty foolproof.

Mike, considering the OP hasn't been here since March don't hold your breath for a reply. :-)

Is this computer still available? Mike

Space Commander, Thank you for the info. So far, my C64 power supply seems to be fine running the Vic 20! AAGDOS

Hi Jerry, My UC07 matches with yours exactly. I set my KDJ11 straps to match yours, too. When I power up, I get into ODT, as I should. I type...

OK !!! YEAH !!! I figured out how the 303 gets onto the Data Bus. Like I said the 2 inverter on C and 2 inverters on D that are connected to D2-D5,...

The power supply is smart and will shut it self down if there is over current on the outputs. I had a short on the 5V rail on mine that was causing...

Well, tearing it apart more, the +12 rail on the power supply was shorted to ground. The offending part seems to be the Zener diode 1n5350 at d25. ...
