So after nearly a year and a half, I pulled this thing out again to try and fix it... Replaced the fuse and a resistor that sits next to the fuse...

If you are talking about the SCELBI, the model to look at is really the 8B. The 8H could only have up to 4k of RAM unless you were prepared to...

Sort of the old carbon disks inserted in the socket of incandescent lamps as a "bulb saver"; essentially a negative temperature coefficient...

Amazing, this solved an old mystery for me

- Ok, this could be it! I'm at home with my son for the morning so cant get to the APC until later but I'll be sure to report back with the result....

How about the 8080? If one includes commercial machines, then it's a pretty hard call. Certainly not any of the hobbyist class, I'd say. ...

I will exclude systems relying on a coprocessor board since that seems a bit of a cheat. 6502: BBC Master seems to be the fastest and most...

Yeah, I'm a firm believer in credit unions as well. Granted, it's inconvenient for it to be pretty much necessary to switch financial institutions...

Cool. Cheers :) yeah It wouldn't be worth it, making mine as flat as they are was painful enough - I actually use normal through hole ISA...

Yes, they are the Tandy adapters. I have one complete in original packaging, one opened with all the original items. I have the instructions too, I...

1. 128MB of RAM in eight 16MB SIMMs is the maximum for the SE/30 (which is basically a slotless IIx in a compact all-in-one case.) 2. For MacOS 6,...

To me a tweener is a machine that exists between two technological gaps, able to access both. It's a very WIDE term. An example would be a machine...

Similar in intent, but instead of worrying about current building over time, this is about a very low resistance being used to just stop the initial...

Well my "bank" isn't really a bank. It's a credit union, so the rules are a little different, and so are the employees and just about everything...

I've been quiet for a couple months because I just spent time on a contract overseeing bailing a banking group (international company that owns MANY...

Has anyone been able to recompile sdltrs on Sierra with the latest Xcode?

Little update, if you have adblock plus installed it's simpler to block now. Someone's making a subscription list that will automatically add known...

My initial question was, what is the best, most capable machine produced that used an 8008. We seem to be coalescing around the MCM on that score. ...

I went around and around with a pair of B51s (or B52s) for another guy that was using them on a Ohio Sci computer. Two different revisions of the...

The 8008 is not a 8080, 8085 or 6502. The 8080 and the 8085 are of the same family but the only thing similar about the 8080 and 8008 is that there...

Someone mentioned they had a TM-100-2A in my thread about the TM-100-4. Perhaps that one would work?

Are they the adapters Tandy made that allow PLUS cards to be installed into ISA Slots? If yes can you post some pics please? I've never seen pics...

All of my Commodore 101 key keyboards are autoswitching (from the Commodore PC-10/20/30 era) but generally if it doesn't have an XT/AT switch, or...
