I pulled out a disk I had sitting here which I totally forgot I had. It's the program 'Uniform', version 2.02, from Micro Solutions and is copywrited 1986. This is the PC version, and I hadn't tried it before because it's been quite a long time since I had a PC with the 5-1/4" drives. Well, I installed it onto the MS-DOS 2.11 boot disk copy I keep with the IBM 5155 and began trying different CP/M formats with it, including Kaypro 4 and Osbourne Executive formats. It read both formats flawlessly, though I've not tried formatting an Osbourne or Kaypro disk on the PC and then reading it on the real machine since Uniform does that as well. The leaflet which comes with the disk says that on an XT, the program supports 110 different CP/M formats, while on an AT it supports 160 (I'm assuming with a HD disk drive). I knew that I could read a number of different CP/M formats using CP/M 3.0 on the C-128, but hadn't given this program much attention before. Is there anyone out there who still uses this program for data exchange?
