Commodore Colt PC-10 IBM 8088 XT PC Clone Computer - #ComMAYdore

The Commodore PC-10 is an IBM PC compatible computer built and designed by Commodore Business Machines in the early 1980s.

In 1984 Commodore International signed a deal with Intel to second source manufacture the Intel 8088 CPU used in the IBM PC, along with a license to manufacture a computer based on the Dynalogic Hyperion.

Shortly after the PC10 was born which was comparable in the market to the Blue Chip PC, Leading Edge Model D and Tandy 1000 line of PC compatibles.

Now it's time to sit back, relax and check out my 1987 Commodore Colt PC-10 IBM 8088 XT PC clone computer video.

Please note: In the video I call the CGA video port a CGI port. It's technically a RGBi port.

Love seeing the obscure systems that I have never heard of/experienced in the past. So much cool history in retro computing!

[NPrescott]

Heck yes!! That computer is awesome! I have seen these throughout the years but never really knew what it was. Love that chirpy chirp from the piezo. Reminiscent of the PET 8032 I used to have.

In most of the machines from this era, there are always an extra slot or two in the back. They were used for cards that needed double slots for expansion. Cards that would use this would be a SCSI controller and it would have an additional backplate with an extra port. Or I have also seen cards that have extra serial and LPT ports back when that was the standard for external devices. You could have a printer, hand scanner and other accessories like a Wacom Digitizer etc hooked up at the same time. I have a Sound Blaster that is ISA and has internal SCSI controller, sound input/output 1/8" jacks, a volume wheel and then an extra backplate that plugs into the main card for stereo RCA jacks. 😃👍

That case reminds me of the Commodore 128D. It has the reset button, which looks the same, on the right side by the back. Same thing, when you take off the lid, it catches the switch. I'm surprised after the 128 / 128D and the Colt, they wouldn't have revised that design 🤔

Super cool video as always!! Thank you for sharing these epic treasures! 🙌

Thanks for showing it off! Definitely has a Commodore feeling to the case design.
5:40 another possible explanation is that it makes sense to have more openings on the back than ISA slots since there were common multifunction cards that needed you to remove two slot covers to have access to all their ports on the back.

I had installed a VGA graphics card going out to a Magnavox VGA monitor on this. I rocked that setup till '93. The mere sight of it brings back memories.

Great video on this computer! I know that Atari made some PC compatibles, but I don’t think that they were very popular, at least not in this country.

[craigsmith]

They had this at the Toys R Us near me in the glass case with all the "expensive" toys including the PXL2000 camcorder. I wanted this computer so badly as a child!

Double mode? Did you say it had an 8088-1?

[siskavard]

Our family had one of these. I learned GW Basic on it

[BollingHolt]

I think that's what the automotive industry calls a three-stage turbo LOL. Hey, do you happen to know on which machines the Commodore 75BM13 display was used? I'm pretty sure it was for at least one of the Commodore PC clones, but I have found very little information on it.

[andygozzo]

i have the motherboard out of one of these i'm trying to resurrect, unfortunately i dont have the case or psu, i used to have the psu but dumped it over 15 years ago as i didnt think i'd need it ..d'ohhh, i dont think i ever had the case, cant remember, where i used to work dumped loads of old computers in a bin and i 'rescued' whatever i could in my break time, they'd all been opened up and hard drives ripped out, quite literally, with some having lots of damage to casing, even motherboards ruined,

[larrywilliams]

Click thumbs down twice. That's a great feature.
