'Free to a good home'

by mbg＠TheWorld.com

>Forgot to mention that the PDP11/04 also has a GT40 & light pen. Then strictly speaking it isn't a GT40... it is a PDP-11/04 with a VT11 and VRxx monitor. The GT40 was specifically a PDP-11/05 based machine (with the mustard color scheme).

PDP-11 QBUS module ordering in BA23

by chrisc＠addpower.com

The pieces are all coming together on my PDP-11...I received my SCSI card today and am waiting on the memory. I've been doing some research into what order to insert the cards into a BA23 -- this is what I've come up with. Any suggestions otherwise? Since I haven't seen the QRAM-44B yet, I'm not sure if it's a half height or quad height board. If it is a half height, do I need a bus grant continuity card in the CD portion of that slot? Starting with the 3 Q/CD slots on top, then the 5 Q/Q slots: |------------------------------------------------------------------ | M8190-AB (quad height) | | |------------------------------------------------------------------ | Clearpoint QRAM 44B | M9047 ??? | |------------------------------------------------------------------ | M8020 (DPV11) | M9047 ??? | |------------------------------------------------------------------ | Viking SCSI | M7516 (DELQA) | |------------------------------------------------------------------ | | | |------------------------------------------------------------------ | | | |------------------------------------------------------------------ | | | |------------------------------------------------------------------ | | | ------------------------------------------------------------------- Thanks, everyone! Wish me luck configuring the sucker... Chris

BOUNTY: Looking for Koby Electronics HS300-01 power supply

by vcf＠siconic.com

I'm renewing an old bounty. I need to find a Koby Electronics HS300-01 power supply circa 1986. A technical manual would also be relevant. This was including in a product made by Interand Corporation out of Illinois. The relevant feature of the power supply is that it would "monitor a network in a low power mode and 'wake-up' if there was activity". Since this is not generally the function of a power supply, it may be that the power supply had some sort of sensing circuitry to monitor a data connection and then fully power up when it sensed activity. If there are any other products circa 1986 that fit this description then that would also be relevant. The timeframe for this is very short: I need something by Monday for my client. If this rings a bell with anyone then please get back to me. I'm paying a bounty for solid leads. Please contact me directly if you've got anything.

PDP-11/40 success (sort of)!

by ggs＠shiresoft.com

After the better part of 2 weeks I've finally gotten one of my PDP-11/40's to execute some code. Both initially exhibited frustrating similar problems. Both were stuck in "reset". This was because the processor was seeing AC-LO and DC-LO asserted. While the symptom was the same, the cause was different. In one case the power supply was not deasserting the signals. In the other, something in the RK-11D was pulling the signals low. I've worked around both but fixed neither. Once that problem was solved on the "first" 11/40, I discovered that there was a stuck bit when trying to read or write memory. This was temporarily fixed by swapping the data-paths module. At this point I could read and write to memory. Memory could be read and written through the front panel, but execution would immediately trap to location 4 (6 showing on the front panel). This was a "bus error". I unfortunately spent a lot of time swapping memory around (this was not the problem). Replacing the data-paths module with another suitably jumpered one solved the problem and the 11/40 happily runs a little test program. However, at this point I'm hesitant to run it for very long since there is an acrid smell emitted while the system is powered on. I don't want to burn anything up until I track it down. The second 11/40 still traps to location 4. I've verified that the memory is good by swapping memory boards and backplane (I'm using MF11-UP memory) with the first 11/40. I checked the supplies and they seem a little low, but it got late tonight and I'll check and adjust them tomorrow to see if that fixes the problem. It's a bit hard to determine if any one card is at fault because the two 11/40 CPUs are configured very differently (which means there are almost 2 dozen jumpers between all the boards that need to be changed). Here's the 2 different CPU configurations: CPU #1 CPU #2 KD11-A KD11-A Basic CPU KE11-E KE11-E EIS KE11-F FIS KJ11-A Stack limit option KT11-D Memory management I have another set of CPU boards (but no extra FIS) that if the voltage checks don't solve the problem I'll try to see if that fixes it. If anyone has any other suggestions, I'd appreciate hearing from you. -- TTFN - Guy
