Re: Making a bootable LIF CD for the 9000/382
9.1 was the last version that works on 68k 9000s It may be I'm trying to use the wrong kind of CDROM drive. Will probably just put it onto a hard disk.

Re: Making a bootable LIF CD for the 9000/382
I'm assuming you are trying to use the newly added HP-UX images on bitsavers? I haven't tried those yet, but I don't remember doing anything special, the install CD is already bootable. I have a V/382 (AFAIK virtually identical with the 9000/382 except for the form factor), and it boots straight from the Install CD, no magic involved. I'll give your images a try when I get a chance.

brain fade, I know I've made a HPUX 9 install CD before but I've forgotten how you make one that can be booted by the LIF boot rom in the machine.

That was pretty easy; thanks for knocking my brain into gear! :-) The first couple of bits I had to fish around, but pretty quickly it became apparent there was a system, and for the rest it was just 'confirm that this chip does indeed hold that bit'. I now have the chip<->bit table for the even words, and most of the ECC bits for them (there are two that have resistor headers next to them, so I can't easily get a DIP clip on them to see which is which), but I'm getting bored, I'll do the odd ones tomorrow. Probably they'll be very similar (the array looks like a mirror image of the one for the evens). Also, I was using a 1MB card, so I only had the low bank to worry about; so then I'll have to do the high bank - again, probably pretty easy, from here. The blasted card doesn't have the usual DEC Exx chip numbers, though! I had to make up my own for it... > I'll add the info to the MSV11-J page on the CHWiki, once I have it. Alas, it's down at the moment (the server is actually up, but its DNS entry has gone away again), but once it's back, I'll get them right up. Noel
Re: MOS 6500/1 ROM archival service
Interesting. I've got a Micropolis 1115-VI floppy drive with this same MOS chip, 2 MHz crystal and all--but with a Micropolis ID. Probably not of any interest to the general hacker public. I believe it manages the buffered seek on the drive. --Chuck
Re: Looking for North star software
I've got a Horizon so native console is no problem. I originally got Dave Dunfield's NST working with my IMSAI and Dajen SCI monitor board, on a North Star MDC single-density controller. I couldn't get NST configured properly with the Dajen monitor (you're supposed to be able to give it a format for poking bytes into memory), so I ended up customizing Dave's RAMless 512 byte monitor for the SCI's serial port and getting loaded up that way.

Makes sure they are configured for the NS* native IO. If they are not your still stuck as then the OS is looking for an IO board that is foreign. I know that as before the horizon I had the bare NS* MDS in the Altair using the SIO as serial. Putting a boot monitor in is by far the easy way out. I did that early on and it has serial transfer and embedded loader for soft sector controller. I rarely use the stock NS* system but the older one with all the changes is still in use. Hard disk (2x 31mb) makes it more useful. There is one excuse I use occasionally for pulling out the stock NS, UCSD Pascal. The first IDE.

Re: Looking for North star software
Yeah, you do need a monitor or something to get started on either Mike Douglas's solution or Dave Dunfield's NST. I've used both successfully. If you have hard-sectored disks, I can just make you a boot disk. I have both single and double density controllers.
