Looking forward to seeing what happens next! I found an 8080A in the bargain bin at Radio Shack back in '79 or '80 and wire-wrapped my own board to try to create my own little SBC. Only had toggle switches for input and LED outputs for data and address lines, had to toggle my programs into the 1k static RAM every time, but it was still fun. Had to design a two-phase clock for it until I finally snagged the 8224 clock chip. Never did locate a 8228 bus controller chip before heading off to college. I've still got the 8080A and 8224 and plan to rebuild it some day (lost the wirewrap board in one of my many moves). So glad your Cosmac still works!
Great memories. I built my first computer with an 1802.( cost 15$ from the US ) getting code in the memory was the challenge , I had 256 bytes of battery backed cmos ram, and switches. eventually finished up wit 2 k of uvprom a 5 inch floppy , plus a crt driver IC . great fum still have the 1802 chip, not the home etched board.
Este fue el primer computador que tuvimos en la casa de mis padres cuando yo era niño. Tenia un pequeño manual con algunos juegos escritos en forma hexadecimal (por supuesto no entendía absolutamente nada). Debíamos digitar para poder jugar. Luego mi papa adapto una vieja grabadora de sonido y pudimos grabar los programas. Este fue mi humilde inicio en la programación y hoy tengo 50 años de edad y aun programo. Dulces recuerdos de infancia que no volverán.
¡Gracias por compartir tu historia! Me encanta escuchar cómo los pasatiempos de la infancia llevaron a una vida llena de alegría. ¡Te deseo éxito continuo!
Great video. I also had the vip back in 1978 , loved it and do not have it anymore. Being one and into electronics most all my life I rebuilt it using not only my own design called voyager which used the classic elf2000 from 2008 from a developer called Bob aka spare time gizmos from his nuts and volts magazine at that time, I used that as a basis for recreating the vip. This along with a cf card, ive recreated most all of the vip programs/games and have them all stored on one cf card. Im really a big part of retro and still am on most all systems since the 8008 and up. The 6502,1802,68k,8051 are all my favs. Ive had them all and still use them all. Ive grown up in this technology since then from the 70's. Love your Idea to redesign a nice large display for the vip,as well. It looks fun, please post more as you get into it. -Retro Btw, I know voyager was not a part of the 1802, the Galileo and Hubble had them, to me voyager is a personal issue 😊
@drfrancintosh not really,I was very lucky back in the early 70s and 80s with a few jobs i had but I just fell in love with the 8 bit,microprocessors we,all grew up with. To this day, I'm still trying to enjoy the now retro look back on what we had and still try to make them more interesting and also to fix them to still keep,it interesting for myself and others. You though are making it really interesting for those who have not seen it. Your videos are awesome and to knew people watching, that explanation will keep it alive for the rca, apple2 and similar stuff we had, towards other future young people to dream like we did. Thank you so much for sharing this 😊
For your info, the chips you're not sure about at 1:30 to 1:40: U10 = CDPR566 - "512 byte ROM", aka CDP1832 with the operating system U13 = CD4515 - "4 to 16 lines encoder", this is hex keyboard interface U24-U25 = CD4508 - "4-bit latches", for the 8-bit parallel I/O port It's all in the COSMAC VIP instruction manual :)
Great video. I'm eager too see how the project goes. My grandfather got my dad a KIM-1 when he was a kid.

My first project was an 8080A that somewhat worked. Awesome fun.

This was the birthplace of the CHIP8 interpreter ❤
Chip-8 Was great... but it was not hard to drop down to machine code. Thanks for checking in!
I had one of these. My first real computer. Absolutely loved it. Still have it though I haven't fired it up in years.
Fire it up! Safely, of course.
I vaguely remember this - thanks for the walk down amnesia lane! Dr. Francintosh’s brother :)
Awesome, I finally got my very own a couple years back...I love that computer and always wanted one as a Kid. :) so awesome you kept yours. :)
Very cool

Youre even more hard core than I am! Thanks for your comments!

Very nice video. I'm itching to try out the Elf I inherited. This was a little bit more motivation.
Glad to hear it. It's a fun machine.
Oh I wish I had kept my cosmac vip and all my old 1970's/80's computers. Buying them again now for nostalgic reasons in 2024 is expensive!
What a beast!
Haha... humble yet lovable 1802

It's all in the COSMAC VIP instruction manual :)
Thanks Bob! I haven't read the manual lately. I'm glad there are other 1802 enthusiasts out there!
Well D0Ne! Thats Really Cool
I cant say I've seen this one before. It's Always the KIM
New Sub; Dryden, Michigan
Thanks friend! Yes. the Kim-1 was quite the darling back in the day. The other thing I remember was the TVT-6.
Where'd you get those LED displays?
AliExpress - I avoid China purchases (they aren't always what's advertised and sometimes don't even arrive.)
