Re: Data Recovery Services

Iv had some luck with drives where the head gets suck in the park position. If the drive spins up then shuts down it could be this. Bit of an agricultural fix but, take the lid off and give the head a slight nudge off the centre and get the lid back on quick. I'm lead to believe this will only

RE: Preferred way of substituting TFT for CRT Monitor?

Yesterday I checked the 9000/217 98204B combo with my oscilloscope and I can confirm the 25kHz horz. frequency (1V down to 0.3V pulses every 40 us). I cannot measure the pixel clock as my oscilloscope was too cheap (I had to compromise) and thus cannot sample at higher MHz rates. I only see

Re: Any Collectors in Italy, near Milan?

Do a search for Olivetti M20. You'll find several people in Italy. The M20 was a Z8000 processor and is more interesting than the 8088/86 machines. Even so, they may connect you to other DEC collectors. Dwight From: cctalk

Any Collectors in Italy, near Milan?

I am going to be visiting Milan in a few weeks' time. I was wondering if there are any collectors on this list who live in that area, who would like to show off their collection, if I can get a bit of time away from the family? I have a particular interest in DEC machines, but other makes also

Re: Any Collectors in Italy, near Milan?

Well.. I'm in Italy but far away... (in the south) You can visit MuPin in Turin. Let me think a bit... I'll post something else. There's a lot of collector, but they don't read this list... -- Vincenzo (aka Supervinx) --==ooOoo==-- My computer collection: http://www.supervinx.com/OnlineMuseum

Looking for an IBM SP/2 (the supercomputer, not a typo)

I was contacted by a guy who works for a computing lab at a major US University on the East Coast who is looking for an SP/2 they can display in their lobby. I have one, but it'll be a monumental pain in the to get out of here. I wanted to drop a line and see if anyone had one they'd be

Restoring Old Paper Tape

I'm tossing this out here as a conversation-starter more than a request for help, although I may end up putting the knowledge to use. Today I received a set of original HP paper tapes for the 2115a machine. I don't know if they've been archived or not - there are dozens of HP tapes on bitsavers

RE: Restoring Old Paper Tape

By all means, let's discuss and it will be a useful and fascinating conversation both now and in the future. But just as a thought for the more immediate issue (your tapes)... I find it somewhat unlikely that a significant number of early HP 21XX paper tapes are not already archived, or in

I know some folks sent an email to me indicating their desire for a UA11 board but others may have waited until they arrived. The boards arrived this week (I'm just getting to it because I was out of town on business). They actually got here a week a head of schedule (yea!). The price will

Re: Preferred way of substituting TFT for CRT Monitor?

The 98549A board is 1024x768, 6 planes (4 color, 2 overlay, at least under HP VUE -- perhaps there's a way it can make use of all 6 planes for color, but I don't know how). Otherwise, that matches what I've observed here. ok bear. On Jan 21, 2016, at 8:51 AM,
