From ROM, rather. There was no OpenFirmware on BeBoxens.

Re: which was the best X11(R4)-terminal?

NCD-19b, -16c, etc - 68k-based models, before any MIPS or 88k models) Weren't 68Ks (020? 030? 040?) a bit slot? Never seen any 88K model, what does it run? VxWorks?

Re: So, that 425t I have that has a 715t label on the front

Also, while discussing board layout, the audio part of your board is almost identical to the A2288 (audio + optional fddi on 735/755), with a set of six orange IC being put in a slightly different grid. The 1821-0050 chip is also part of the audio half; all the other 1821 chips are for video.

Re: So, that 425t I have that has a 715t label on the front

I'm trying to get more info on the card. HP barely mentions it in their part lists, and no one else seems to know much about it. miod, how did you know it was a VRX? I didn't know and I made a typo; I meant CRX. I initially thought the video part of that board would be a packed version of the A1659...

Re: What pointless thing are you doing right now?

Checking the state of my SMD disk cabinet after my last relocation accross the country. Looks like one of them will need another low-level format, but my SunOS setup is not working anymore, I'll have to reinstall from tape. Looks like a nice weekend project. Hopefully it will be raining outside, so ...

Re: DECStation 5000 / [20,25,33] RAM

I have checked and I indeed still have 4x2MB (5019464-02) 80-pin memory simms for Personal DECstation. Last used about 15 years ago, they were in working condition back then, have been stored carefully in a dry place, can't test them anymore unfortunately.

Re: DECStation 5000 / [20,25,33] RAM

Finally scared up a R4000 processor for the old girl. Lovely! So.. this thing has 8mb on-board, and can take 32mb (4x8mb) for a total of 40mb which would be grand. Giving away my DECstations has been one of my worst mistakes... However, I _should_ still have a set of 4x2MB memory for the personal D...

Also, since the 9000/350 has my only HP-HIL cable, if anyone has any others they'd like to sell (I have keyboards, just not cables), please PM. I'll have a look, but I don't think I have spare HIL cables. Remember however that HP-HIL supports hotplug nicely, so you should be able to move your keybo...

Re: So, that 425t I have that has a 715t label on the front

However, you appear to be correct about the video board. There's a small DIP switch block on it but it doesn't look like a DIO select code block. This is definitely an SGC board - DIO-II boards also have two connectors on the edge, one large and one much smaller. This seems to be the regular CRX bo...

Re: So, that 425t I have that has a 715t label on the front

This is one of the two in-chassis upgrades available from HP. You could get a 425e upgraded into a 705 (or 710?), and a 425t upgraded into a 715. While the 425e upgrade made sense as it has exactly the same chassis as the 705/710, and the motherboards share the same form factor and external connecto...

Re: What extremely rare (non-prototype) computers do you wish you could find?

But, yes, I have dumped some really interesting things in the past, SUN VME systems, System/36, AS/400 plus many more. Still, I can't turn time back, and I'm happy with what I have. That's the spirit! A friend once called me because his lab's Sun 4/470 was getting recycled, so if I wanted any parts...

Re: No graphics out from Indigo2

There actually are no jumpers on the hard disk, I checked. It's just Molex and SCSI 50 pin. That's very unlikely, if only because you need jumpers to set the SCSI ID. But jumpers won't be between the power and scsi connectors, they will usually be somewhere on the electronics, sometimes on the side...

Re: No graphics out from Indigo2

A bad CPU wouldn't send the signal for the hard disk to start, would it? If your disk is jumpered to auto-spin, the mere application of power will spin it up (sometimes after a delay). If it isn't, it will not spin until a "test unit ready" command is sent to it by the PROM, which would i...
