sash64 missing?

My copy of the 6.5.29 overlays doesn't seem to have sash64 in the root of the first cd. fx.64 is located in /stand where it should be but no sign of sash64. What is up with that?

Re: 80 to 68 pin SCSI adapter on Fuel

Alright here is the info. I believe this mod is only required on systems with a U160 bus like the Fuel. The Fuel expects differential mode but the pin on the adapter isn't connected. That means the drive is set for single ended (SE) mode. Making a simple voltage divider and pulling the pin high puts...

Re: 80 to 68 pin SCSI adapter on Fuel

After reading through the drive specs and poking around with my meter I have it working! When the interface “DIFFSNS” line is between -0.35 V and +0.5 V, the drive interface circuits operate singleended and up to and including 20 M transfers/s (Fast-20 or Ultra SCSI). When “DIFFSNS” is between +0.7 ...

80 to 68 pin SCSI adapter on Fuel

Does anyone have experience using one of those cheap SCSI adapters? I'm trying to get a Fuel to recognize a 73GB SCA drive but it never shows up in hinv or spins up. I tried an 18GB SCA drive with the same result. The cable seems to be alright because it sees a standard 68 pin drive. The specs for t...

Re: System failed pre-power check (Fuel) FIXED

Just wanted to say that replacing the yellow battery fixed the problem. It powers up just fine now. The l1 still has some weirdness. You can type "serial" and get command not found. Type a few other commands and then try "serial" again and it works. No typos or backspaces were pr...

System failed pre-power check (Fuel)

I'm having problems with a Fuel that won't boot. When issuing the power up command in the l1 monitor it gives the error "System failed pre-power check". Any ideas how to proceed? The environment monitors were all disabled so I re-enabled them and reset the l1 but it still gives this error....

Linux on POWER5

Well I picked up a POWER5 box from eBay recently, its a 9111-520 (dual 1.5Ghz and 4Gb ram). It's pretty quiet and runs AIX 7.1 great so I decided to see how Linux support was... It's terrible. Every distro either fails to boot or boots into an unusable state. Redhat Enterprise 6.8 was the only one t...

PCI 5250 card software

I found a surplus seller who sells 5250 PCI cards for $10. They have the 15 pin connector on them so you can connect up a twinax splitter and run a software terminal. I have located drivers that appear to work in Windows 7 (32 bit). Now the next piece of the puzzle. Does anyone have a copy of the IB...

Re: PS/2 to USB converter

Thanks for the tips everyone. Building an Arduino based adapter would be satisfying but you can't beat the convenience of ready made :) For the record I'm planning on using a Sun type 5C keyboard from a javastation on my main PC.

PS/2 to USB converter

Can anyone recommend a converter that will let me use an old PS/2 style keyboard on modern hardware? There are a bunch of cheap devices out there but the reviews are mixed. Thanks.

Re: IBM AS400 E series 170

This would not have been my plan of actions. Maybe though the disks are in the incorrect positions? Where the disks mounted RO ? I wonder if they were indeed written to? AS/400 formats the drives in really odd sector sizes of 520 bytes or even 528 bytes. The drives also have unique firmware with ex...

Re: Two AS/400's (720's)

Nice find! I'm currently in the process of getting my own 9406-270 up and running. Have you read about the AS/400 architecture at all?

Large Scale Systems Museum

Posting this for a friend of mine. Stop on by if you want to check out some "big iron". Most of you have heard of the Large Scale Systems Museum, a public museum in the Pittsburgh area that is focused on minicomputers, mainframes, and supercomputers. LSSM opened its doors to the public for...
