< Allison, just how compatable were the Rainbow and Decmate ll. With what? if each other the answer is not at all. The Rainbow was sorta PC(ish) using z80 and 8088. The DECMATE used a PDP-8 cpu reduced to a chip. Differences, PDP-8 is a 12bit machine and the other two should be familiar. < I have a Decmatell Word Processing 2 book manual no disks and < another Decmate Hardware Configuration Manual with a System < Test Disk and a system overview disk which I have viewed on my < "Bow. From all the diagrams they were identical in appearance and < seemed to have used the same keyboard and monitor. IIRC from < the R'bow fido docs I downloaded from the Finnish site the Bow < could use SCO UNIX (?) Was the 'bow able to access the mini's ? The used a similar box, same Floppy (RX50), if it was installed the same 5/10mb hard disks, monitor and keyboard as those were all coperate standards for that era. other wise they were three different machines (the pro350 was similar style and peripherals).
