PDP-8 diagnostic tests

Hi, I have written a PDP-8 VHDL model and I have it running in an FPGA https://github.com/scottlbaker/PDP8-SOC At this time it has passed a basic DEC diagnostic instruction test but I found some interesting things when getting that instruction test to pass. For example: The following segment of

PDP-11 RL02 disk emulation

Hi, Has anyone built or had any experience with this (or any other) RL02 emulator? http://www.pdp11gy.com/indexE.html#file:///E:/homepage/indexE.html Thanks, Scott

PDP-11 RL02 disk emulation

Hi Noel, >> Any chance it could be put into 'production'? Sure, if there is interest, I could make a run of boards. >> Also, what FPGA board are you using? I assume it's one that has an SD >> card socket or something, for actually storing the bits on? My project is just an interface board for

PDP-11 RL02 disk emulation

Hi, The author of this project http://www.pdp11gy.com built a wire-wrapped board to interface an RL02 controller (RL11, RLV21, or RL8A) and an FPGA development board (which does all the heavy lifting for the disk emulation). I decided to build one of these

PDP-11 RL02 disk emulation

Hi* >> Any chance it could be put into 'production'? *I placed an order today for 3 RL02 emulator interface boards from OshPark. I expect it will take 2 weeks to get the boards back from OshPark. I am leveraging RL02 emulator work from Reinhard Heuberger, but I am using a newer FPGA board than

Update: After removing all the boards, checking jumper settings, etc. and reinstalling everything again. I am please to announce some progress. The PDP-11/23 now boots up to the diagnostic monitor. Thanks very much to people who replied with technical help and particularly to Glen Slick who

PDP-11/23 system for sale in Portland Oregon

Hi, Pictures can be found here: http://sierracircuitdesign.ddns.net/temp/pdp11/ The system is located in Portland, Oregon. Local pick-up is preferred. Not sure if it still works. I have not tried to turn it on in years. I do not have any software of floppies for it. I'm not sure what it's worth.

Bootable 8" floppy needed for PDP-11/23

Hi, I have a PDP-11/23 system with a DSD-440 dual 8" floppy drive. On reset, it prints: 28 START? and waits for the operator to insert a bootable 8" floppy and type DY0. The problem is I do not have a bootable 8" floppy. The DSD-440 should be compatible with either RX01 or RX02. Can anyone on

[cctalk] Re: typical IC kits on Amazon and elsewhere

Been lurking for a while, but this topic hits true with some recent experiences. I would not hesitate to buy most common digital ICs on Amazon or ebay, but I usually will not buy analog ICs other than from trusted sources, such as Mouser. I have bought LM2596 voltage regulators that oscillate at
