IBM 6094 Lighted Programmable Function Keypad - Some Documentation...

by lbickley＠bickleywest.com

I didn't find a lot of information from IBM support on the 6094 - but I did get some. I have uploaded a old copy of IBM's RS/6000 Graphics Handbook which describes the IBM 6094 LPFK. The LPFK information is found in section 4.5. The good news - in can be attached to a serial port on an RS/6000 or PC - which means that it shouldn't be difficult to find the protocol for the critter. Not a lot of info in the manual - but something is better than nothing ;-) You can download a PDF of the manual via anonymous FTP from my website: ftp://bickleywest.com/IBM6094 Lyle -- Lyle Bickley Bickley Consulting West Inc.

VAX 2000 FPU test ?

by dave06a＠dunfield.com

Does anyone know how comprehensive the pwer-on Floating Point Unit test (9) is in the Vaxstation/uVAX 2000 ? Does it actually verify that the FPU is functional, or is it just looking to see if some basic indications are the it is present? The (9) FPU test is performed at power-on, and also by >>> TEST 9 I'm trying to determine if the FPU in my VS2000 is actually working. Will the console ROM run (normally) without an FPU? Unfortunately the (hopefully more comprehensive) system tests don't appear to test the FPU (or perhaps they don't see mine and therefore won't test it). Can anyone with a VS/uVAX 2000 tell me if: >>> TEST 80000106 >>> 9 Actually runs a test (mine just displays the testing header and halts. Another thing to try which takes longer is to run >>> TEST 102 And note which tests it runs. Mine runs: F (video) - Only if set to VS2000 C (Serial) B (memory) 7 (Hdc) 6 (TPC) Noteably missing are: E (clock) D (nvram) A (mmu) 9 (FPU) 8 (Timer) 5 (Interrupt controller) 4 (color FB) - I've got it removed 1 (Ethernet interface) - I've got it removed as well. All of these pass during power-up and TEST n tests (if I have them installed). Problem is, I don't know if the system tests are supposed to test these or not - I don't have a known good Vax2000 to compare with. BTW: To run TEST 102 and 80000106 you need to have the system test "hardware key" installed - this is just a DB-25 connector on the serial-port with pins 12 and 18 connected together.

Sun ND server?

by trasz＠FreeBSD.org

Is there an implementation of Sun nd(4) (Network Disk) server other than the one in NetBSD, by Matt Fredette? Long story: Few days ago I fried SCSI controller on Indigo 2, and I'm not gonna risk the same with my Sun 3/60. Few months ago I got SunOS 3.5 kernel to netboot using modified NetBSD ndbootd(8); it goes as far as mounting rootfs. Then, just after printing the following line... using 95 buffers containing 778240 bytes of main memory ... it just retries reading block number 16 over and over. I guess the ND protocol implementation is wrong somehow. The whole transaction goes like this; the only thing that changes is the "seq" field. RECV: minor 0x00 error 0 vers 0 seq 29 blk 16 bcount 8192 resbcount 0 curroff 0 currcount 0 op 0x01<READ > XMIT: minor 0x00 error 0 vers 0 seq 29 blk 16 bcount 8192 resbcount 0 curroff 0 currcount 1024 op 0x01<READ > XMIT: minor 0x00 error 0 vers 0 seq 29 blk 16 bcount 8192 resbcount 0 curroff 1024 currcount 1024 op 0x01<READ > XMIT: minor 0x00 error 0 vers 0 seq 29 blk 16 bcount 8192 resbcount 0 curroff 2048 currcount 1024 op 0x01<READ > XMIT: minor 0x00 error 0 vers 0 seq 29 blk 16 bcount 8192 resbcount 0 curroff 3072 currcount 1024 op 0x01<READ > XMIT: minor 0x00 error 0 vers 0 seq 29 blk 16 bcount 8192 resbcount 0 curroff 4096 currcount 1024 op 0x01<READ > XMIT: minor 0x00 error 0 vers 0 seq 29 blk 16 bcount 8192 resbcount 0 curroff 5120 currcount 1024 op 0x01<READ > XMIT: minor 0x00 error 0 vers 0 seq 29 blk 16 bcount 8192 resbcount 0 curroff 6144 currcount 1024 op 0x01<READ > XMIT: minor 0x00 error 0 vers 0 seq 29 blk 16 bcount 8192 resbcount 0 curroff 7168 currcount 1024 op 0x11<READ DONE > Any ideas? -- If you cut off my head, what would I say? Me and my head, or me and my body?
