Almost 12 months ago, I posted here that I'd picked up an NEC APC that was in bad shape.
Well, I finally got around to obtaining a set of boot disks (thanks glitch). After cleaning the diskette drives (removing black gooey sludge that was once foam pads and cleaning the heads) I tentatively booted her up with the CP/M-86 diskette inserted. At first, the [ * ] prompt changed to [LOD] then [LER] then nothing... I'm guessing that LOD means loading and LER means load error.
Simple mistake, I'd put the drives in the opposite bays - the termination and select jumpers were still correct so I just rebooted but with the diskette in the other drive. Low and behold the prompt changed to [LOD], then [LOD C], and finally brought up the following CP/M-86 screen. Yeah...
The last line is garbage (appears the same each time I boot up) with the flashing cursor after it. As I don't have a keyboard yet, I'm stuck at this point. However, I'm going to try and mod the CP/M-86 to take input from the serial port (thanks again for the idea glitch). So, next step is to hook up the diskette drive to an old PC in order to access the files. I've even found on Dave Dunfield's web site an NEC APC disk image that appears to contain CP/M-86 bios source code. I'll report how I get on.
