Hi Again, <snip> The original lot we used ran CPM/86. As the IBM continued to grow in market share a version of MS/DOS modified specifically for the Victor was released. The wierd disk format came from the multi speed floppy drive and the zones. 600K on one side of a 5-1/4" disk. Not bad for it's time. Yep, due mainly to the disk format. Can't remember if there were problems with the video driver portion also. The system had a very high resolution. I once saw video being played on the screen. Looked every bit as good as a black and white TV except it was green and black. In any event, you just couldn't bring programs straight over. As far as applications went, they had Victor versions of Lotus, Supercalc, MultiPlan, Multimate, dBase II, Crosstalk, Wordstar and others. It even had a 3D spreadsheet called Victor Calc. There was talk of Victor releasing a disk drive that would read and write IBM format and an emulation board that would allow it to run IBM software. As I remember it, this board was giving them all kinds of headaches. Never really got it to work bug free or at least free enough so that users wouldn't complain. Shortly after this the company went belly up. Seems that they were will established over seas and had a good share of the market. In an attempt to migrate the system to this side of the pond they overextended themselves in the marketing department and opened up too many sales locations all over the country but the sales didn't materialze. I remember them shutting down location after location. That's about all I can remember. Hope that helps. Tom
