Re: Raised Floors

I should have been more clear in my last response. The 2x2 grid of the floor tiles does not extend to the floor, but to an intermediate layer with wider spacing of the supports at the floor level.

Re: TU58FS

Hi     It does not have to be done using TU58. If you would be so kind as to explain the bit about SIMH and dd. What to do is good.. How even better. If I can get  a bootable OS image onto the SCSI drive with what I have available then that's all I  need. Rod Smallwood On 24/05/2019

Re: TU58FS

Yes you can. Basically you can boot an image and then prepare the volume on the hard drive and copy it over. I have a PDP11 page on my Classiccmp site that walks through it. There’s also a long thread on the VCFE forums about it. classiccmp.org/cini/pdp11.htm

TU58FS

Hi     I am working on getting my KDJ11-E based system up. I have a CQD220A and a SCSI hard drive installed and formatted. A serial connection to a Raspberry Pi soon brought up the console on the PDP-11 using TU58FS. Next will be a second serial line to allow TU58 emulation. SFSG What is

Re: Raised Floors

Purdue's insurer REQUIRES fire sprinklers in data centers. And it's not atypical from what I've heard. They are all dry, pre-action systems, which eliminate most of the danger of it accidentally dumping water. It's unlikely that with a dry pipe, pre-action system water will be dumped somewhere

Weird... now I've pulled it apart (taken the case off and pulled out the keyboard... and I get many wrong characters instead of no characters... Hmmm. I wonder what happens if you take all the screws out of this thing? I hope it's not like an IBM AT keyboard and 83 tiny springs fly out... On

Hi Mark, I have a contact in Belgium who has made some PS2 adapter PCBs if you'd like me to put you in contact, he was advertising them on Facebook a week or so ago. -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest private home computer collection? t: @binarydinosaursf:

Re: Apple ][+ Keyboard

- There are lots of PS2 adapters on the market, I made one myself - There are lots of PS2 to apple II schematics avaiable. One of them uses just ONE PIC µC - The keyboard encoder was reverse-engineered by Victor Trucco, and I believe I've seen others around Lots of options :) ---8<---Corte

Re: Apple ][+ Keyboard

Hi Brian, That's an interesting thread. It probably is the encoder chip as hitting Ctrl-Reset works. Unfortunately Briel Computers doesn't seem to exist anymore. ): This seems like a temporary solution. I need to collect the stuff to build one: https://knzl.at/ps2-keyboard-for-apple-ii/

Re: M7264 Troubleshooting

> From: Jon Elson > Yes, this is most likely a bus timeout The good news is that it looks like his CPU is 'mostly' working; and if the NXM is due to a fault on the CPU (e.g. bad bus transceiver sending the wrong address), that would be fixable (it uses 8641's). If the fault is in the
