PDP-8/i Panel Pics

Hi Guys I sent out a photo of the new PDP-8/i with a real one for comparison to everybody who might be interested. If you did not get the email and would like one please let me know Rod (Panelman) Smallwood

PATA HBA and drive wanted

Hi: I'm looking for a PATA host bus adapter card (either ISA or PCI) and a PATA drive preferably UDMA/33 but no later than UDMA/100. This would probably come from a system built in the mid-1990s before the PATA interface got embedded into the chip set. It might even be from an older system

Taking this forward 30+ years, Silicon Valley is a period drama that gets significant details spot-on right - both in the gross generalizations that are network TV and in the nuances targeted to the cognoscenti. I work with several people who could be the template for Gilfoil. There was recently

MicroVAX II Console Garbling Characters

I have a MicroVAX II which has started garbling and losing characters output to the console. It had seemed that re-seating the processor board would fix it, but that no longer seems to be the case. I was just wondering if anyone else has ever come across this failure mode? Regards Rob

Re: PDP-8 diagnostic tests

Kudos for working on a VHDL model. Which 8 variant are you trying to model? As others have stated, the IAC does affect the link. Of the other instructions that one might think could change the Link, the ISZ instruction does not affect the link and indirection that uses the autoincrement memory

Who said anything about it being a documentary? It's a period drama largely based on the kinds of flamboyant personalities that pioneered much of the personal computer industry. While retro computers are in the show, I don't view it as being about the retro computers themselves. On Wed, 24
