Hello, I used to work on one of these in the early 80's, targeted at the Z80. The system comes in 2 big boxes with a HSI "high speed link" between them. The bottom box which manages the 2 8" floppies was run by a DEC LSI-11. Yes, the floppies (if they still exist) can be duplicated (even the system disk) after you have booted into system (using the system disk). The console instructions was in some scaled down form of UNIX. The system I used was unreliable and cost a lot to fix. I have studied the internal circuitry and it seems to be an overly complicated ICE system (compared to the Zilog or the Intel Intellec system of the same genre). The company at which I worked eventually went belly up, and they junked the system. If you are trying to use it as an ICE, it may be better to look at the Microtek ICEs which are PC hosted. The only thing you lose out will be the "virtual IOs" function on the TEKxx. Hope this helps, Jeff At 04:49 PM 10/30/02 -0800, Tom McClintock wrote:
Anyone have any Tek 85xx development docs? I'm hoping to get some big 8" floppies created on on of their development stations read. FWIW, the discs in question are double-sided.
Should be interesting if the data can be read...
Thanks, tom
Two excellent suggestions/info thus far. To Aaron - I do not believe it is RT-11 format. Anyone else? The CPU in question is a 68000. Like what you might find on a, oh I don't know, Cosmic Chasm PCB? I'll let everyone know if the disk reads are successful. tm Jeff N K Yeo wrote:
