Nice work Paul. -Rik

The 380, 345, 375 , 382, 385 and 400 series all share the same chipset for memory and internal bus (processor support) The difference is made by the peripheral chips and I/O bus, the 400 series have a

From the 9000 series the330/350/ 360/370 have the fastest HP-IB ports, I’m not sure about the 380/382 because those also have a SCSI chipset and need an option board for the Fast HP-IB option . But th

Yes, nice work. And a clean look, I have to try it sometime (time is the keyword😉) -Rik -----Oorspronkelijk bericht----- Van: VintHPcom@groups.io <VintHPcom@groups.io> Namens Dave McGuire Verzonden: v

The PSU of the HP-9816A hasn’t been build by HP it’s an external sourced part, and isn’t really HP build quality. The low voltage elco’s will short sometimes, I’ve seen 3 in the last 10-15 years. But

Yes, basic should boot the viper -Rik

Sven, I also have a Viper board running on RMB 6.22 without any problem, but the base system is a Vectra ES12 running MSDos 5 . You should understand, when the Vipers were developed the fastest proces

HP-UX on any 68k which is not a 68040 costs a lot of coffee ;) -Rik

Marc, Tony's diagrams are the product of very clever reverse engineering. But keep in mind he made them about 15 years or more ago, when there was a lot unknown about signal names and internal working

Dyke, I've read the article on Steve's site, that's why I asked for the serial number of his machine. The elastomers (I wrongly called them polymers) are almost 46 years old, and the experience with t

Peter, I use IPA to clean the contacts, also for the polymer, those are hold together with some kind of paper gasket. If you gently clean them and move your cleaning tool in the same direction as the

Peter, What's the serial of your unit? Another thing, the HP 9825 and HP41 share the same polymer connection system. A small rod made of polymer with gold wire on it for the connections. In the HP41 t

Peter, You probably did this all ready, but did you tried changing the EPROM's to eliminate a defective one. And what's the 'speed' of the EPROM's you're using? -Rik -Rik

Jay West, had a few of the made a few years ago. May be he has the drawings of the bracket. -Rik
