Re: My Fuel now has a power supply and Dallas chip, but no graphics yet. Can I connect to it over serial?

I would recommend getting a bunch of DB9 and DB25 F/M to RJ-45 shell adapters and a pair of DB-9 and DB-25 serial break out boxes. Convert everything back and forth from standard DEC (a.k.a. Cisco) pattern modular jack serial connections. It's a bit of an upfront cost, but everything becomes so muc...

Re: Indigo 2 Hard drive compatibility

How should the id be assigned? On the SCA-to-50pin adapter PCB there's a row of a dozen or so jumpers. Look for the jumpers marked ID0, ID1 and ID2. These can be used to assign a SCSI ID between 0 and 7 in binary. Installing a jumper on ID0 and leaving ID1 and ID2 open sets SCSI ID to '1'. In just ...

Where a simple 3-wire cable works for a serial console, you should really use a cable with hardware handshaking for the L1 connection (or anything at 38400 and faster). And configure your console program to use it.

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

let's talk about alternative: Linux? Well, there's always QNX. Anyway, the software is only part of the picture. I can still get interrupt latencies 3 .. 4 faster on a 10 year old PPC MVME board than on the latest and greatest x64 consumer hardware. These days all buses are serial (PCIe) and there'...

I think so too. You get something on the L1. Some complaints about lack of I2C communications (with graphics board, I assume).

But it wont boot.

Re: IBM AS/400 OS/400 questions

the licensing tiers on just about anything in the machine will drive you wild. Is it the same licensing scheme (LUM) they use for e.g. the xLC compiler on AIX? That has it's roots in NetLS, and I happen to have reverse engineered and keygen-ed that :) (NetLS on IRIX, not LUM on AIX). It's fairly st...

Re: Indigo 2 Hard drive compatibility

Use a 68-50 pin adapter. Except we're looking at a SCA disk, not UW (68pins). What's needed is a SCA-to-50pin adapter. Something like THIS . HERE you can see such an adapter in action. You do have a disk sled, I hope? Otherwise you will need to get one one. You set the SCSI ID of the disk with jump...

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

Why your comment is so negative? VxWorks is a RealTime OS, certified to be used in avionics, automotive, etc. Having more than a decade of vxWorks experience under my belt, let me say this: * The licensing costs are very high. If you want vxWorks 653 (certified for critical operations), licensing c...

Free for pickup: CRT monitor from a 4D/35

Pretty sure this one originally came with my 4D/35. Should be 19" or 20", 1280x1024 with BNCs on the back. It worked when I put it in my attic, but that was a decade ago. I'm doing a bit of spring cleaning and it has to go. Free for pickup in Wijchen, The Netherlands. If it's still here in...

Re: Anyone see this beaut on eBay

I suspect the buyer is just a collector who doesn't care about using the computer. He/she simply enjoys to own it. Therefore I wonder if we'd better make some replicas, like in the movie industry. The Van Gogh museum sells replica posters as well, but they're not worth a lot of money, nor would an ...

Re: Indigo Keyboard/Mouse converter

I'm all for a v2 of this device, but it would be nice if the firmware was open. The current design doesn't work in combination with a PS/2 KVM switch (tried at least 3 or 4). I contacted the author of the current design many many years ago but never got an answer.

Re: Midnight commander - F1-F10 keys

I think GPM is Linux-only, but try ESC-1 for F1 ... ESC-9 for F9, and ESC-0 for F10

NB: this also works on Linux, OS-X etc.
