Thanks to Dennis Wingo, Vector former employee from engineering, for this information:
Historically, the Vector 4 can be seen as a transitional system, especially for Vector in the quandary in 1982 concerning whether or not to compete directly with the IBM PC.
The system shown below had a 6 Mhz Z-80 CPU and an 8088 "I think" also running at 6 Mhz so it would have been faster in processing than a standard 4.77 MHz IBM PC.
The I/O for the system was the S-100 bus but with a reduced functionality so that it was only used for the FD/HD card and other I/O mapped boards. The
original memory was 128 kilobytes with the ability to add a daughter card that would extend this to 256 kilobytes.
The Vector 4 had a much better graphics capability than the Vector III although I can't recall the resolution. The Vector 4 originally booted CP/M and also had the LinkNet 750 kilobit/sec token passing network card as an option.
Interestingly enough by the time of Comdex in November of 1982 we had the LinkNet integrated to the extent that we could have 32 computers all linked together AND you could map ALL of the disk drives from the entire network onto whichever system you were working on.
In March of 1983 I did an install at Digital Research (inventors of CP/M) of a networked system and between Vector and DRI we implemented CP/M 86 that used the much faster 8088 CPU and had all of the same networking features that we had in CP/M-80 as it became to be called. If it had not been for some collusion between IBM and other parties, we would have had commonplace networking a decade before this actually happened....but that is another story!
Anthony Lefco reports:
This computer had a hard sectored floppy. Later a soft sectored model became available so that it was more compatible with prevailing standards. It also had an option to convert to an 8086 chip through an installation by TRW. It came with a full suite of proprietary applications.
This was my first computer. I remember it well. It was murder to figure out how to get the data out when it was time to convert to a new computer as the company quickly went bankrupt, but it did force me to learn about computers in more detail.
