From: Joe <rigdonj(a)cfl.rr.com> one below despite the fact that the opening bid was only $25! FWIW One of our well known Florida pack-rats that's on this list also has a working(?) BASIC 4 and I think he has docs and SW for it. That's Georgia pack-rat, thank you. Hell yep, David Greelish and I hoisted his old Model 1300 Basic Four with two drives in it up a staircase with the help of another nearly killing all three of us. I later got it down that same flight of stairs myself without serious injury (so far) and it's still nearby. I do have BOSS, Business Basic and some business apps for it on some RL02ish disk packs. I also have the Planning & Installation and service manuals on the CPU (LD1200 cpu, SM1101 semiconductor memory, SM8001 and LD8001 sync comm controller, and SM9000 and LD9000 power supply) DRIVES, TERMINAL, and PRINTER. Some info from SM1029, July 1 1976 Service Manual for Model 1300 CPU The model 1300 CPU is a general purpose, 8-bit, microprogrammed minicomputer (lots of ttl). It is the primary unit of all BASIC/FOUR computer systems. The CPU has full I/O capability, an interrupt system, a DMA channel for data transfer between the CPU and one or more disk drive units, and an internal main memory of up to 65k. The memory cycle time is optionally 1.0, 0.8, or 0.6 microsecond. Macroinstructions are implemented by executing a series of firmware microinstructions stored in the microprogram ROM. Elsewhere in that manual it also states that the capability of two CPUs to exhange data directly is also available as an option, So, I wish the other one were closer and am glad it's not. ;) - Mike: dogas(a)bellsouth.net
