USB-serial adapters (was: Hans Camenzind, Inventor of the 555, dies.)

by d235j.1＠gmail.com

This little device seems to be the cheapest FTDI-based USB-serial adapter I could find. Not sure what level converter chip it uses since I haven't torn it down, but it seems to work with everything I've used it with so far. http://www.amazon.com/gp/product/B003TYCHIC/ref=cm_cr_rev_prod_title --Dave

The Manchester hoard of 7090 stuff.

by peter＠vanpeborgh.eu

Guys, We have decided that the 7090 artifacts should go to the National Museum of Computing at Bletchley Park, England. Partly for patriotic reasons: the use the computer was put to in the UK. Also, we decided it is what the owner, a British pioneer of medical computing, would have wanted. Lastly, TNMOC assured me that they would be prepared to make copies availble of anything requested by outside museums and collectors. The items should be with them by the start of October 2012. It was good to discover that two complete 7090s with support documentation is available in the US and Australia. That also weighed on the decision. I do hope they will one day be reactivated, when I will be delighted to come and have a look around! Kind regards, peter vp || | | | | | | | | Peter Van Peborgh 62 St Mary's Rise Writhlington Radstock Somerset BA3 3PD UK 01761 439 234 || | | | | | | | |

Interview 8200

by electronicdan＠hotmail.co.uk

Hello. I have a Telenex Interview 8200. After the self tests, it asks for the system disk and then to press any key. There is hard drive activity, but it seems that the system software is not present. Is it possible to obtain the software for this unit? Thank you. Dan.

Apple 1 insanity continues

I wonder where he got the scan of the manual from I came across this link today: http://www.applefritter.com/content/seems-another-apple-1-replica-newton-1-… According to posts there, the guy building them goes by the name "Mike Newton" and also has photos on Google+ at https://plus.google.com/u/1/photos/109866693740649982432/albums What I found odd in the Applefritter thread is that another person going by 'michael0623' started that thread, and then 'Mike Newton' shows up and mentions "michael0623 has helped to advertise a bit and he went further by helping me to list one set of Newton 1 on Ebay". This sure looks like spamming to me, but maybe someone else will spot something I missed. While 'Mike Newton' claims he didn't copy Mike Willegal's Apple I reproduction boards, it sure looks to me like he did. http://willegal.net/appleii/apple1.htm Supposedly this guy has made some sales, however I'm not buying his story. Anyone can do a buy-it-now on their own items, which is actually allowed per eBay policy, (although /bidding/ on one's own items is /not/ allowed). http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=251109274976 I call shenanigans.

My 2/120 has six serial ports, a monochrome connector, and two RJ11 connectors on the back. One RJ11 is for the keyboard and one is for the mouse. I believe that two of the serial ports are on the CPU and four are on the SCSI controller. The keyboard and mouse serial ports are on the monochrome video board.

Sun 1 Computer LIVES!!!

by nick.allen＠comcast.net

Not sure of the memory, will need to look that up. I do have a sun 2 keyboard, I wonder if it is a possibility to connect it to the bwtwo video board exclusively for the keyboard use, while maintaining the bwone video board at the same time for video use. ------Original Message------ From: David Brownlee To: nick.allen at comcast.net Subject: Re: Sun 1 Computer LIVES!!!

Seeing and hearing a Spitfire flying around above you adds a whole new dimension to seeing a stationary Spitfire in a museum. Recently I went with two of my sons to see the exhibition "Three tons of minicomputers - 40 years with computers in the service of Uppsala University". Both of them are very good programmers and interested in computing, and they found the exhibition very interesting. However, if the exhibits had been running, and they could have heard a line printer or an ASR-33 printing, seen and heard a disk pack seeking, seen the blinkenlights etc, it would have given them a much better idea of what computing was like 40 years ago. That wasn't possible as the exhibition was only a temporary one, but had it been permanent, I definitely agree that they should have been shown running. /Jonas

ETI Mags

by thannabus＠gmail.com

Hi there, I saw your post some where and I thought I would reply. What I am doing is "scanning" in all my electronic magazines, and saving them as *.pdf files on my hard drive. I do remember seeing a 6802 project some where, I skipped it as I am more concerned with 6502 CPU based systems. My mags are from 1977 up to 1992 and this is ETI (UK), PE and EPE. I am now coming to the end of the ETI mags. If you want that article on the 6802 CPU, I can scan it and forward it. I am not sure what sort of copy right trouble this will invite, but as no money will exchange hands, I cant see them getting upset or anything Cheers Trevor
