- I have installed a Centram Tops for the PC card in two of our '386 boxes.
- This software shows version 1.02, ca 1985. DOS 5.x is on each box. I have the
- registration cards.
-
- Each system appears to load the driver. When entering the topsmenu, the show
- servers command does not find any servers. A handy oscilloscope shows that
- there are bursts of activity when the show servers command is activated.
- Depending on how I interpret the data, I think that it is sending at 118KHz.
- I have not traced the DMA or Interrupt on the receivers, but both machines
- transmit.
-
- I did instruct tops to "show the server."
-
- After exiting, I often obtain a Extended error 1 when trying to "type
- <filename>". However, more <filename works. When the topskrnl.dat file
- incorrectly specifies that a drive is unused, it disappears after the topsmenu
- session.
-
- I am aware that this software is not compatible with version 2.0.
- Accordingly, I have completely disconnected the Macs from the PC's (now you
- comp.sys.mac.comm readers know why I'm here) However, these are serial
- numbers pc100006313 and 6315, and I believe they should talk to each other.
-
- 1) Is there a tech support or upgrade contact for tops/centram? The phone
- number given for centram systems is apparantly to a residence.
-
- 2) Does anyone use this vintage card with a 33 MHz machine?
-
- 3) Does anyone out there have a Mac running System Version 7 connected to
- PCs? What do you use?
