8086 upgrade/conversion on Mega ST?


Recommended Posts

 

 

My buddy received this Mega ST in where he works. It has this board in place of the CPU. I do not know much about Atari computers, but it appears to be maybe some sort of 8086 DOS conversion? Can someone identify?

Thank you

If my memory is correct this is the PC Speed. It adds PC compatibility.

Hello,

 

This is indeed a PC speed.

It was faster than the original PC, because the Atari did the I/O and screen.

It's very much compatible with a PC.

Made by Sack. Needs a disk to drive it and of course a Dos3.0 or so.

Later, a 286 and I think also a 386 were made.

PC Ditto was a software emulator.

Supercharger is a PC connected to the Atari with the DMA.

I rememeber wanting to get one for my STe cause of all the DOS-based programs my college was using at the time. But the local Atari dealer talked me out of it saying that caused problems in the sandwich style cases where the 68K stopped working.

 

Well knowing back then what i know now I could have gotten a used PC, make an AUTOEXE.BAT file tell DOS to send all text output to the serial port, use a null modem cable and run ANSITerm to use the ST as a terminal for the PC.

Hello,

 

As more often, Google is your friend: http://www.atarimania.com/utility-atari-st-pc-speed_23201.html

I searched for "Atari ST PCSpeed and it was the first hit....

 

DRDos worked very well on this emulator.

And there's a 386 version, called "AT Once" in both an ST and MegaSTE version.

Yeah, I'll have to read Atarimania some more on this. My Googling for Atari "PC Speed" landed me here: http://wiki.newtosworld.de/index.php?title=PC-Speed which confirms visually what it is.

 

Thank you,
