Vector 1
Vector 1+
Vector 1++
Vector MZ
Memorite 2
System B
8080 CPU (in late 77/early 78 CPU changed to Z80 and speed increased from 1 Mhz to 4 Mhz over time.)
1K increasing to 48K Ram over time.
Flashwriter 1 video pcb , changed to FW 2 over time.
I/O 1 (Bitstreamer 1) pcb again upgraded to I/O 2 board
Prom/Ram pcb (2K) but was updated to 8 K.
As above but with 2 Micropolis “16 hard sectored” 315 K floppy drives (five and a quarter inch)
All the above systems were housed in the MZ 18 slot chassis
Information given below to be treated with caution. I didn’t come across these early systems so I cann’t be 100% sure of my facts.
Vector 1 series was a clone of the
Altair 8800 and probable shipped with 1K of ram but expandable up to 8 or 16K.
These systems slowly evolved into the other systems as each new pcb was produced so it is hard to actually define where one system ended and another started. It was a process of evolution.
It is possible that the Memorite 1 & 2 systems were turnkey systems and booted from Proms
I came across one System B with 56K ram, using a 8K and a 48K ram boards. Memory boards could be added to the system to give a larger amount of memory.
It was possible for Vector systems to access 512 K of ram using 8 x 64 K memory boards and paging them (via software control after setting switches on memory pcbs)
