I occurred to me this morning that there might be someone out there that may be able to help me.... I've got an old TDL/Xitan (remember them, older Z-80 fans) system including ZPU-2 (with DMA, memory management, and interrupt hardware in disuse), SMB-2 (and a SIR gathering dust), K128 with 64K (and 2 K128s with 128K also gathering dust), and a DDDC. I've been running ELDOS for years, but I've been getting further and further behind the times (and less compatable). I've got enough hardware to put together a significant (for a Z-80) system, but I'd settle for 64K CP/M 2.2. Does anyone have a such a system running CP/M 2.2 or (pant, pant) CP/M 3.0? I'm looking for a BIOS source primarily for the DDDC disk handler (the more disk formats, the better), but I'm also interested in interrupt driven I/O, clock support, DMA, trans-64K memory support.... Any assistance beyond "get rid of it" will be appreciated. Over the years I've collected (and written) volumes of software for the thing, which I'd like to keep access to. Besides, after Zilog gets off their bum and makes the Z800 available, I'm going to replace the hardware with a *real* 8-) machine. Thanks. -+- Sid Maxwell, DEC @ Spit Brook Rd, Nashua NH "TDL and Xitan no longer exist, so I doubt that anyone would care much *regardless* of what I said about them...." -------------------- Please note that this mail message is likely to be incomplete.
