Компьютер "Robotron 1715(M)"

[AlecV]

micko, Ah, yes. 1715 and 1715W (also known as 1715M) were two different machines. I personally saw a uPD765 (i8272A) in the 1715W. AFAIK, the floppies from the 1715 are readable but not bootable under 1715W. Also 1715W had a 256K RAM with CP/M 3.0-compatible BIOS mapper. The software from the SCP2 (1715 CP/M 2.x clone) is compatible with 1715W SCP3.

Did you consider to implement a 1715W with MESS framework ? MESS has a good library of the emulated chips and devices, including i8272A, Z80 CPU and Z80 I/O chips.

JFYI: The 1715W 5" floppies are readable/writeable under Linux with fdutils/cpmtools. I sucessfully transferred alot of CP/M software to the 1715W floppies. Unfortunately, CP/M games do not work, since 1715's ESC sequences are ugly (VT52?? ADM-1 ???).
