hey guys, i am new here but i love classic and vintage computers. i was an avid byte magazine reader back in the days. i remember one issue that covered newer computers such as the Einstein, Mindset and some others.

one computer in particular i am trying to find allowed the use of add in cards that would allow it run software such as ibm pc, apple 2, cp/m and one or two others.

does anyone know the name of this computer? i am pretty sure it was between 1983-85. i know thats a few years. i am trying to find old issues of byte online and doing online research but not with a lot of luck.

any help or ideas is greatly appreciated!

I know the Apple II had add-in cards for Z-80 CP/M and 8088 MSDOS with Wikipedia listing a couple more. Obviously, the Apple II has hardware for Apple II compatibility.

The Mac could get add-in cards for IBM PC and Apple II though I don't know of a hardware card for Z-80.

Many of the other 80s computers had cards advertised to emulate most anything with IBM PCs being most common. There were S100 cards for all the major CPU models so one could have 68000, 6809, 6502, Z-80 and 8086 in the same case. I don't remember any system specifically sold on the idea of running other systems software. You might want to look up CompuPro which advertised the many different types of CPUs that could be installed.

There was the Diamond TrackStar which was an Apple II on an 8-bit ISA card, so one could build an Apple II compatible PC. I know there were a few manufacturers who built PCs around cards like that, can't recall the brand names off hand.

Where's the Apple II compatibility?

I bet it was the Dimension 68000. The time period fits, and it supported several different architectures by way of hardware 'emulation' cards. I also don't believe it worked very well... but it was a cool idea at least.

Interesting. I don't think I have previously heard about the Dimension 68000.

DimensionDude on YouTube has a few videos.

I have Terry's old Dimension 68000. Plugged it in and it works great. Only problem is I don't have the keyboard so I'm stuck.

I remember an advert for an Ohio Scientific computer that was the size of a filing cabinet (so, not cheap), it had a Z80, a 6502 and an 8088 microprosessor inside.
