I still have one of these lying around... Kaypro 4 with the blue keyboard from the Kaypro 2. Because I found it at Goodwill for 30 dollars without the keyboard ;) still works

I had one of these, my uncle passed it down to me in like 1984, and I played Parsec on it nonstop, and I am pretty sure I wrote some simple BASIC on it as well. I never really had a way to follow my tech interests super far as a kid but I wish I had. I also had a Commodore 64 later on. I just turned 49 today and I downloaded the Classic99 simulator and had fun with that today. Fun memories.

Love your channel!

The PS/2 is pure nostalgia for me. I took a keyboarding class in tenth grade and this is the machine we used. Loved every moment of that class.

The prompts were not annoying to me at 15 years old. High School had one computer for the entire student body in the computer lab. I stood in a line across from a second line to purchase mine. I took it home with the tape deck and played Pirates Cove and Hangman. The second line was for Cabbage Patch Dolls. I bought the discounted computer and played and always remember it fondly. I'm glad, you took the time to share. I might have been 14 years old if I bought it in 1981. ❤🎉 God Bless you 💖 TRUMP 💜 2024 FREE Steve Bannon FREE the January 6th Hostages 💜 Keep men out of women's sports 😮 Keep boys out of girls locker rooms 🎉

Got the 400 mini, its been out a few months, it is a cool item.

The Amstrad cpc 464 was my first micro computer back in 1984. I have still got a working unit and I gets regular use I absolutely love the machine. Great video👍🏻😎😂.

Hi Terry, just found your channel and this segment on the 99/4A. Back in the day I was the programmers at Sierra On Line responsible for adapting the title Jawbreaker from the original Apple II platform to the TI. I fondly remember writing the code in 100% assembler. Many of the other programmers on the team were quite envious that I had the "luxury" of 16 bit registers to work, while they were confined to the 8 bit CPUs of the day (6502, Z80, 8088). The TI did make use of SPRITEs using the TMS 9918 VDP (Video Display Processor). Collision Detection (when two sprites merged) was built into the VDP registers to make it easy to detect when one object hit another (genus!). The VDP was great 8 bit processor in it's day. Was also found in the MSX series computers worldwide. Jawbreaker made use of a unique sprite mode of the 9918 which leant itself weill to the larger format of the spinning faces used. TI kept a "closed architecture" on the production of ROM cartridges which helped to limit 3rd party game development on ROMS. They insisted that that if a game were to be developed on Cartridge it would require a license from TI. Perhaps why there are so few 3rd party programs on cartridge. The cartridges made use of special ROMs (Graphic ROMs or GROMs). Commodore eventually drove the industry to its death to the benefit of the customer.

4:10 You called the PS/2 pizza box and now I can’t unsee it.

This was my first 'personal computer', a surprise Christmas present from my mom which was a heavily discounted closeout featuring all the peripherals. As they say, "You never forget your first".

I doubt you will see this, I'm a few months behind. I own a Tandy trs-80 with three monitors, two expansion drives, a ton of games and programs on floppy .

about 4 months ago or so, I was looking around on youtube and stumbled across this specific video. i remembered having this old IBM computer as a child, my earliest memories of my life are actually of using this computer my father had bought, it cost a lot at the time. I remember when I was 4 years old i found a disk in my dads computer area called Mixed Up Mother Goose and my dad loaded it for me and let me play. I feel like thats when life began, with me flying into this world on a large goose to solve some mysteries and have some fun before i departed. anyway, your video sent me down a rabbit hole in which I had to have this computer back. it took me a few months but using ebay, I found a 5153 monitor, the IBM 5150 itself, a hercules CGA card and one of those mechanical keyboards and several old games I remember playing as a kid like the Sierra quest series. the monitor is still in the mail, I hope it arrives safely. Anyway, i wanted to thank you for inspiring me to get the computer back, it means a lot to me. its a physical manifestation of my childhood and now that i understand more, Im having a great time learning about stuff like exploding tantalum capacitors, unlubricated disk drives and anything and everything about these wonderful units. Had a brother in law from Hamilton in New Zealand, he passed away unfortunately. your accent reminded me of him. Thanks again my good sir 👍

History lesson thankyou😊

The CPC464 was my first PC. I learned to code with that (excellent) manual. Later I upgraded to a 6128 and I'm still having fun with that today. As with the C64 and ZX Spectrum, the homebrew scene for the CPC is still very active. Not only are there plenty of great new games and demos coming out every year that really show what the hardware can do when pushed to its limits, but people have also given it a multitasking graphical OS (SymbOS), and there are hardware expansions available to add extra memory, hard drive, wifi, cartridge support, dual sound chips and other fun stuff. And then of course there is the CPC Plus range...

I love my Kaypro 2X but I have a 4 also and though they look the same none of the software will work between them, even software from Kaypro is not compatible between machines. I think that was a big mistake on their part, I wonder how many people had a Kaypro 2 and got the 4 only to find out none of their software would work on it.

It would have been so great if i would have had one of these when i started high school, but that would be nearly impossible for my parents at those prices and the machines limited capabilities. We really do have it good these days.

Atari acquired the rights to distribute Space Invaders, but apparently allowed the programmer to "improve" on it with his own ideas. Supposedly, he wanted to adapt it to better use the horizontal orientation of the TV screen compared to the vertical orientation of the arcade version. If you want a more faithful (but unlicensed) version of Space Invaders for the 8-bit Atari, Roklan's Deluxe Invaders is great. It's plays just like the real thing. Oh, and the 400 was also my first Atari computer. I was 26 when I bought it in 1982. I considered an Apple II, but they were four or five times the price. What sold me was Star Raiders.

fun fact: My neighbour’s father worked on the marketing material for this PC. The one in the commercial, with all the software, he took home to his son, so we had all the games. We played the hell out of it. Hunt the Wumpus was my favourite for some reason. :)

Thank you for sharing. Should try to find Star Raiders for your collection, too. 😊

Colour screen eh? Fancy!! Mine had the green screen version.. Still awesome to 12 year old me though until I got my first Amiga.

THIS is the BBC model B 32k computer that I had, growing up - and I played games on it, composed music (before MIDI) and learned to program - and I have that job right up to today

From what I could figure out online, in 1978 an AUD pricetag of $1,340 would convert to $1,577.72 USD, and inflation calculators show that $1,577.72 in 1978 would have been worth $7,587.28 today. 😐 *goes to live off-grid somewhere*

Hi Terry, great video. Could I please use some of your footage for a videoclip I'm making in homage to amiga computers? I would put a link in the description of the song to your video, and I would just use some very short clips from here and there. Thanks in advance!

9:45" jajajajaj lol....de aca venia el Sea Dragon de Atari 800XL jajajajajajaa

Thank you for showcasing this important piece of history that often gets overlooked by the commodores, TRS 80s, and early apples.

the original cpc 464 had chunky keys....i know i had one back in 1984

That was my first computer when I was a teenager in the 80's. I taught myself to program on the TI 99/4A. My career path would have been severely impacted without the influence this computer had on my interests and technical skills.

This brings back a lot of memories

I had one one our these. All the way up to the max. I bought it at radio shack. It was fun. I wrote my own check book program.

First computer I had and managed to upgrade over time. Ended up with 48k piggy backed and a few other adds like fitting the extra keys to the keyboard pcb at the top for the extra characters and to use as function keys

The kaypro II uses a short persistence green phosphor? I don't see any afterglow on any video

I had one of these in the 80s. It was a great little machine. I taught myself BASIC. I did video as well as text games for my sons. Those were the days…

None of the CPU mentioned in the videostream don't have the ability to accelerate encryption algorithms and it is only recently that there are instructions like ... AESDEC AESDECLAST AESENC AESENCLAST AESIMC AESKEYGENASSIST PCLMULQDQ have become available to speed up encryption and decryption.

The reason why the FPU was sold separate was to make some more money for the manufacturer but nowadays you get chips like the A10-7800k and INTEL XEON ©®

As of Apr 29, 2024, Bill Cosby is still alive. @1m57s

i remember this computer. though it was physically attractive and tempting, it was expensive.. we eventually got a commodore 64.... a great buy!

Great work, Terry. I do agree with EgoChip though, the low-res does fit a video describing anything related to retro computing. ;)

How difficult was it to repair the system to fully functional condition? I just found one in a public auction but am afraid to turn it on for fear that I might damage something.

I'm 58, The TI99/4A was our first family PC. I learned how to write basic programs on this machine. I wrote a variation of PACMAN with twice the number of Ghosts. Good times :)

Thank you for this. I’d been trying to work out what computer it was I had when I was around 10 years old in 1997ish. I knew it was an old computer for the time but when I searched for 80s computers, I tended to get the American ones. Finally worked out it was the CPC 464 and this video was a wonderful shot of nostalgia. It’s what got me into computers and gaming as a young girl, something that’s stayed part of my life ever since.

I have fond memories of the Ti-994/A. A friend and I wrote an assembler language program called 4A-Talk that ran in the Mini Memory Module and let the 4A communicate using a modem at speeds higher than 300 baud...which was the Terminal Emulator II limit. It sold reasonably well and was marketed by DataBiotics -- I think that was the name. It's been a while. We added code that allowed the TI user to send a binary file to a BBS using XModem by including a header block identifying it. It was much faster than the strange TEII protocol that limited data transmission to seven-bits. That protocol spread out two bytes of data over three seven-bit chunks. Plus, normal BBSes did not even come close to understanding TEII file transfers. I do remember that the XMODEM header contained a string with the file name and was limited to ten characters. I think that string came from a data structure created to access the disk. In any event, when we published the specs so others could use them, for some idiotic reason, we wrote that the filename in the header should be space-padded RIGHT justified. Where the heck that "right" came from is still a mystery as the native disk structure was left justified. Anyhow, the mistake got perpetuated because others started using our proposal. For example, there was a group out of Australia named FunnelWeb that had a very capable suite of applications. Their terminal emulator used the header structure we proposed. I'm pretty sure they wondered why the heck we had used such a strange, non-native format for the filename.

I have that game ported to the 80586 but you have to enter a code to access the last level.

What a gem! Back in 1987-88, I had the opportunity to work with some of those machines when my high school peers gravitated towards the CGA Amstrad 1512 for its gaming capabilities. I was more interested in programming and comparing the processing speeds between the formidable IBM machines and my ZX Spectrum, along with other Z80-based 8-bit computers. It was slightly disappointing to find that the 8088 at 4.77 MHz was only marginally faster. However, the design of those machines, much like their manuals, is utterly iconic-comparable to an old Ford Mustang or Porsche 911. They are timeless classics that maintain their value. Even today, I can easily imagine myself typing away on one of those machines if I were a creative writer.

As an 80's kid I desperately wanted an Apple 2 (and later a Macintosh) of my own. But was handed down one of these instead. /:

Brilliant video Tezza. I still have a fully functional CPC 464....it now has pride of place in my bedroom. Yes, my Sega Mega Drive, Super Nintendo, Sega Saturn, PS2 and PS4 are in the living room hoojed up to the large tv, but the Amstrad came with it's own colour monitor! Only thing I don't have whereas you do is the cool manual....I learned BASIC from that and have been coding ever since. Thank you for sharing the light on my beloved CPC :D

Why do I remember seeing this video at least 10 years ago?

I had this exact model and monitor in the 80s. I loved the heavy keyboard. Did not have a tapedeck, so when I programmed something it was lost forever. I actually bought a new Trs 80 to place in my museum. Don’t know if it works actually. I bought some components to build a replacment psu. But being a busy programmer I did not find the time to solder it on a board. If anyone know where to buy a complete psu. Please let me know!

Would it be hard to one day convert all my disks to SD cards? How long per disk might it take?

There is an Android app that plays cdt files so you don't have to convert them

I don't have a desk with enough depth for that setup (well, none that isn't already dedicated to something else), but I have to say, it does seem like a very fine budget upgrade over the TRS-80 Model 1. Neat!
