I found my first PC! How well does a TRS-80 Model 4P hold up after 37 years? Let's find out... 

Awesome to see a Model-4P. Played Scarfman (Pacman knockoff) on a Model-1.

Wow! Very nice machine! Old computer that can show history and size of CRT and mono / color and 5inch Floppy and Speed of old CPU. Old computer like you shows is very nice to coputer education.

Thanks for the memories! My Mom and Dad bought me a Model 4P when they were first available in October, 1983 so I could write programs in Basic for their business. My parents had a Model 3 and then added a Model 4. I upgraded my 4P by adding external modems up to 4800 baud. I also upgraded the Z-80 to a faster one and doubled the RAM and replaced the right drive with a 720K 3-1/2" drive that plugged right in and worked immediately. I then added an external 40MB hard drive which made it run very fast for the day. I also wrote a script for a terminal program that I had purchased that would dial numbers looking for other computer modems and log the numbers - I got the idea from the 1983 WarGames movie. Back then there was no Internet and we connected to dial-up BBS systems usually running on private computers like the TRS-80s. I now have 2 or 3 Model 4Ps in my house somewhere, but I have not fired up any of them in a very long time.

I grew up with a Model III. Big Five made the greatest stuff! Lucky you, finding one of these again, and working no less! Take good care of it!

I'm cleaning out an older family home to get it ready as well. In there I found a brand new ti-99. Beautiful. I still play with BASIC but I use an emulator so I thought this would be great. My aunt worked at texas instruments during the time when the ti-99 become worthless if you remember that. She got hers for basically the cost of materials of it as they couldn't sell them for any price and had truck loads of them. She didn't know how to use computers so she never used it lol. She just couldn't pass up the deal. The internet here was none existent at the time so we all thought it was a digital type writer. I remember hearing about sending digital letters like an email or bulliten board service. I remember saying something like but letters are so cheap. Why buy an expensive machine? lol Good times!

I had a Model I as a kid, and I remember having Scarfman and Super Nova on it. I have seen documentaries about the kids that were behind Big Five Software, and they built up a nice 6-figure bankroll for themselves selling those arcade clones advertising in 80 Micro Magazine.

I still use my model 4P once in a while. replaced the original diskdrives with Double Sided/DD white coloured drives that fit perfect with the cover of the 4P. Also had the capacitors of the power supply board replaced after I got the fantastic (and smelly) magic smoke of the old capacitors. Thanks for posting this video of your model 4P.

The first computer I ever played on was one of these. It belonged to my uncle, he still has it, and like yours it still works.

I've seen one in working condition back in 1999, somehow it came over the pond to Europe! Lovely 1980's design! So much nicer compared to the ZX Spectrum clones using the same CPU (I know, different market targeting).

great games!! :D

It's all your fault! Now I have one on its way. Great video and a very cool machine! I subscribed.

I had this baby. It weighed a ton. 😂

Very little to go wrong in those old computers. They didn't have nervous breakdowns like today's laptops.

I pulled out my still working 4P today. The awesome intro to Attack Force @14:37 is a nod to the Si-Fi TV series "The Outer Limits"...20 years before the 4P came out. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FCcdr4O-3gE.html

They built computers to last a lifetime in those days.

I want a cell phone with that power button.

wow

You should replace the electrolytic capacitors, they don't last for ever.

San Antonio?

Crazy a computer with no internet..

A very shaky video

y-yes, but quite frustrating video: the audience can't read a thing on the screen. too far and too wobbly...
