Interesting credit at the end of this. I am sure Hawking wasn't interested but, who is this Dennis guy ? Someone here I bet. https://www.youtube.com/watch?v=09nTwccQTUA

I have a bunch of random Adaptec cards for sale. $6 each with shipping included in the US. I've tested each one to boot fine except for the Mac versions card. I don't have a way to test those. They are the ones sold by Apple and were pulled out of working machines. (2) AHA-2950U2B (PC Version)...

This is just a matter of curiosity but, I saw this auction http://www.ebay.com/itm/PDP-8-DEC-Flip-Chip-Wire-wrap-Backplane-Digital-/170884861695 . I was just curious how you would deal with something like that. Seems like there is no telling what's been wired to what or if changes had been made...

Are there other possible replacements for the Mostek MK4332D-2 ram chips ? Here is a description of them There are a couple for sale on ebay but, for crazy money and I need four. I don't care about looks so, I'm ok with anything compatible that is maybe less desirable to chip collectors.

I have an empty pedestal 11/73 case I'd like to repopulate. I know the combinations are basically endless but, I want to make it as original as possible. Slow memory and all. What would be the standard out of the box board set that would have shipped from DEC ? Hopefully the exact part numbers...

A good friend of mine passed away recently and I was just thinking it would be fun to relive the hours we spent in front of his model 25 taking turns playing Ultima when we were a whole lot younger. If anyone has a system they could sell cheap or for shipping please drop me a line. It would be...

I have 820-I with a mess of disks. Some are originals for the 820-II. So far I haven't been able to read a single one that says it is specifically for the 820-II. Did they change disk formats ? I know they had a 8/16 upgrade for the -II that did MS-DOS. Some of these could be in that format but...

I am trying to do a full system backup to QIC tape on an old CISC box but, have run into an issue. Operator error I am sure. Its running R2V3. I get the backup going fine but, when I hit the end of the first tape it pops up a message saying to put in the next tape and hit enter. The problem is...
