All ? Mike Douglas added support for the MITS 88-HDSK hard drive system to my Altair32 Emulator. Right now, there?s only a dialog box to interface with the code so I?d like to make a nice on-screen graphic like I did with the floppy disk. Does anyone have access to an 88-HDSK that they can take a picture of the front of the unit and send to me? I would greatly appreciate it. Thanks!

Osborne I almost ready! - Looking for disk images (double density)

by webmaster＠supervinx.com

Hi! I found and replaced a faulty 4116 ram chip: I used an oscilloscope to monitor pin14 (DOUT), and the faulty chip showed no activity at all... Now's the trouble: where can I found some disk images (double density)? My O1 has the DD upgrade. I found only a DD CPMSYS disk image, but it hangs after having loaded the HELP. The floppies which came with the O1 are almost unreadable. Only one could be read (by now). This disk boots the O1 in a minimal CP/M: setup works, xref works, but mbasic and cbas2 hang. I searched the web, but links have been outdated... Thanks!

You need to add either another dual board to this configuration, or an M9047 grant continuity card to fill up the space next to the SCSI controller. Once you hit slot 4, there can be no open slots in between boards. Tim

That means the boot ROMs in your CPU board don't have VCB-02 support in them. (Same as mine.) My notes show the device address was set to 777402 (Gee, that looks like an octal address. So much I've forgotten about VAX stuff...) I think the 3 LEDs come on at power up, and then go off in a quick sequence when the device driver configures it. Is this a VMS or Unix-derived system? I know VMS 4.7 had the drivers for the QDSS (VCB-02), but if you are using an older OS, not sure. As the boot ROMs don't support the frame buffer, you should not expect any display until the OS is up. Other than making sure the I/O address was set to a value so that the driver enumeration could identify the board, I did nothing special to configure it. Jon

All, I've added a VCB02 card to my MicroVax 2. Right now the VAX is setup with the following layout... Slot 1 KA630-A CPU M7606AF Slot 2 8M RAM M7609-AM Slot 3 8M RAM M7609-AP Slot 4 CMD SCSI MSCP encapsulating (top half) empty bottom Slot 5 M7516-YM (ethernet, top) M7546 for TK-50 (bottom) Slot 6 VCB02 Slot 7 VCB02 Memory Slot 8 VCB02 Memory Per the docs on bitsavers, the VCB02 can go in any QBUS slot 5-8, but the layouts in the manual are different than what I have setup. With the VCB02 in there POST takes longer, but the console still comes out on the serial port. The VCB02 shows 3 red LEDs. I assume I need to set the addressing on the card, but I have 0 clue what to do. -- -Jon Jonathan Katz, Indianapolis, IN.

I am looking for a bbs/fideonet database for Australia that lists the nodes that existed in the past so I can see if there were node around my location ? --- tom_a_sparks "It's a nerdy thing I like to do" Child of the Internet born 1983 PGP ID: A7EF6006 Please use ISO approved file formats excluding Office Open XML - http://www.gnu.org/philosophy/no-word-attachments.html Ubuntu wiki page https://wiki.ubuntu.com/tomsparks
