Activity Stream

I don't recall if someone posted a pointer to the video card so here it is: http://retro.hansotten.nl/uploads/files/RM%2065%20CRT%20Controller.pdf...

Thank guys, got the card working, I've used the MIO v2.1. As you said I don't have HD floppy support, I wasn't looking for this anyway. If I need it...

The 8MB hard drives had key switches even on the secondaries so power up/down of a multi disk setup must have been fun.

The machine I have, used the Euro Cards but all of the boards were made available in both types. The cards with the E at the end were Euro card types...

I can make some guesses on some of these, (the ISA card looks like a SASI adapter), but the resolution is far too low for me to read part numbers. ...

Am I being extra thick today, or is there some other repository than Kyle's in which these changes can be found? (I don't see them in Kyle's...

I'll agree about the order, mostly. But you do *not* want to insert cards with the component side facing the rear. Vince

I coudn't see the comments, as they seem to have moved them to the very bottom, and I have to try to scroll past the bottom of the page; then they...

We have been using the non-Omnibus serialdisk on a PDP-12 for quite a while on a 9600 baud serial interface. Works just fine.

Eminently feasible. It's easy enough to read data from the cassette using ROM routines. You'd have to write your own disk formatting and sector...

The order of the cards actually don't matter at all. DEC documentation have an order given, but putting them in backwards, or placing them elsewhere...

Nice scope.

If/when you want to replicate a RAM card, I can help as I have the 32k dynamic RAM module, manual and schematic. I also have the 8K static RAM...

Very nice. I noticed the backward cards too. Glad he did also.

I ordered a digital scope, a Siglent SDS1202X-E, https://www.amazon.com/gp/product/B06XZML6RD/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 and it...

That does look interesting, curious what the costs would be. If it's less than the PetSD+, it would be the way to go since the PetSD+ is basically...

Wow, I’m shocked to hear all of that. These are usually pretty robust from what I can tell. Probably a silly question, but are you using the...

Dwight, I decided to use the Euro connector version on both the adapter and the the video board. The reason being that the adapter board...

Panasonic seems to have made at least a short run of them at one point. They're called LT-1 floppies. I don't have any, but I'll keep an eye out for...

It's picked up in one of the user comments below. He's very methodical and plodding in a good way.

I bought one as "turning-on" from eBay, but it actually didn't turn on, PSU is dead. Down about 200$ I then bought a working PSU, and thank fully...

I'm watching the first one, and it's nicely done so far. One thing that seems odd to me is that it looks like the CPU and memory were inserted...

Via chipsets had worse memory performance than Intel ones. Even with SDRAM compared to EDO, reads might be a little faster but writes are probably...

My error there... MUXA was working in earlier plots... MUXA will be a bit indeterminate with no CPU fitted as it is partially derived from R/nW...
