“Tandy” as a corporate entity ceased to exist around the year 2000 and simply became “RadioShack”; the “TRS” in TRS-80 was specifically an acronym...

I guess "only supposed" is from a user perspective. There's no BIOS or any other simple command you can use to do it, so as a user, you'd need to do...

Don't really get the question. The fact that it says it was made for the "Radio Shack TRS80" does not even indicate that Radio Shack had anything to...

He made 4 posts so far and they all start with "I've got". Not sure what to think about this. ;)

I hope I never accidentally buy anything from you... When shipping electronics, an anti-static bag is a must! Among many other causes, static...

I've bought from vcm on occasion. I can't figure out if the guy is a genuine enthusiast or just a huckster who has glommed onto a hobby to make a...

The ISA bus amazingly never had a defined clock speed, so there's technically no overclocking, just setting an arbitrary clock speed. Earlier ISA...

I recommend the shrouded connector. It's just too easy to shove the connector on off-by-one. I dealt with a similar issue with the power cable to...

Actually, a dead board is easier to fix than an intermittent board. It likely has one bad part that is easier to find. As for anti-static, it is...

Answered my own question again.. maybe. Apparently you use MODE COLOR and that switches it. Seems kinda a silly way to do things though... if...

Glad you worked it out. Have fun! FWIW, if you want to try that 2K drive on a PC, just call it a 3.5" 720K.

You do realize this thread is nine years old and the OP hasn't been to these forums since that time right?

Guys, I just wanted to update on the situation with the dead Eagle IIe mainboard. The seller Vintage Computer Museum on Ebay responded to my query...

I changed out the original Tandy 2000 boot disk I got with the machine and switched to a disc I'd made via an image off the net. It boots too, but...

What’s your plan for programming the part? Or more specifically, making it easy for an end user to write to the part? I considered making an adapter...

Answered my own question. The answer is no - that 7414 has a bad inverter. Swapped out.. voila.. it boots. :) Track 0 matters, apparently. ...

Is tipc the vintage computer museum seller on ebay?

It wouldn't be hard to remove that broken pin, the issue like you said is melting the plastic. It wouldn't be easy to lift the plastic up without...

Are you speaking of chips, systems, or both?

Im so glad i sold off my mca soundcards last year for top dollar (sealed in box) as these will brimg down the value! But so glad they were made!...

Excellent! :thumbsup:

Well, that looks nothing like the 120VAC version but no-doubt an equally effective design. I don't think a 230VAC schematic exists so that's handy...

It's an 8086! Full 16 - looks like a DeskPro 8086 derivative.

"When ordering the board, you may want to specify a card edge bevel of 20 degrees (details of the bevel are included in the Dwgs.User layer). This is...

Yeah and cling wrap creates a ton of ststic. And packing peanuts.. Anyone ever been shocked reaching into loose (non biodegradeable) packing peanuts?...

Interesting investors saw value in RS name as it is still doing business worldwide but investors saw no value in maintaining TRS80 name. Well all...
