Jared: I was looking at the 53131A specs and the minimum input spec for 100MHz to 2.7GHz is -27dBm and from there to 3Ghz is -21dBm. I guess actual levels would be less than that , but not

Dave Your post helped a lot . I think I found the cloned memory info by Dr. Scott M. Baker : https://www.smbaker.com/a-basic-and-ram-board-for-hp-9000-series-computers Maciej

Ed The connector is part of the machine and the memory card uses PCB edge as connector. There is a raiser inserted in onto the 3852A processor board like the one below. The memory card interfaces

If the CRT has an intact heater & shiny silver getter, it is probably fine. Lack of EHT is more likely to be a problem, especially if there are leaky paper based capacitors in the EHT circuit, or a

Hi Tom In the folder 07 Recent uploads it is listed as but no to download HP 83620 86340 86350 Synthesized Sweeper Service Manual-HP8360-SeriesComponent-LevelServiceManualVol1&2 Kind

One more generic question: up to now I have never seen any evidence that the CRT is working, if I get to the point of having the whole circutry working again and I discover that the CRT is not

Hi David, I saw that DIMM like socket on Agilent pictures. However my HP8563E is older (don't know the year) and A6 PCB has no such board. Regards, Michel [email protected]> a écrit :

The first thing you should try is to reseat the power supply module in the main power supply. This module is similar to a memory module in an old PC, and it plugs into a DIMM socket.

I’ll have to look at the schematic again, as I didn’t notice the dependence (also) of 88V on the 300V supply. HP simplified their ‘scope power supplies subsequently, making one supply the

I have a blank display on my HP8563E. The CRT is fine but I found out that -15 VDC power supply is down (LED on A2 is off). I measured nearly 0 V on TP303 (vs TP301) on A6. Anyone came across the same

Nice! If that is in fact an HP-9000 DIO RAM board, they've already been cloned. A fellow over in .eu did the design, I had a small run of PCBs done and built a few, and eventually got it

Hi Tom, The file is in the RECENT DOWNLOAD list. We have to wait for verification before we can do the download.

Ozan, Thank you for the tips.? My observations: 1. I was able to verify +15VF, +5A and +10UF voltages directly on A7.? I need to get an extender to really dig into it :-( 2. In the system

If the connector is still available, it would not be difficult to make a 1MB or 8MB static RAM board. I did one not too long ago for the Data I/O UNISITE that also uses the MC68000. The original

Am I too stupid to find it or hasn't it been verified yet? I'm excited to see the CLIPs. Tom DG8SAQ

Sorry a correction, by disconnecting the J9P interpanel connector I have disconnected the V33 heater so I could not have had the right voltage out anyway from the -150 supply, regardless I was getting

I haven't looked up the pinout because I really need to get to sleep, but from the photo this board looks *exactly* like a DIO bus RAM board for an HP-9000 series 300 computer.
