Anyone want up to 3 MicroVAX 3100 Model 30s

by robert.jarratt＠ntlworld.com

I have 3 MicroVAX 3100 Model 30s given to me by someone who is leaving the country and could not take them with him. I took them rather than see them discarded. They each have 8Mb onboard memory. They do not have any disks and the cover on the storage bay is missing. One of them has a little bit of damage to the rear plastic panel. I cleaned out all the dust and powered them up, they all booted to the console prompt just fine. They are in Greater Manchester, England. Regards Rob

retr0brite not so right?

by spectre＠floodgap.com

This appeared on the cbm-hackers list today. Anyone have a thought on it? Addresses redacted. ----- Forwarded message from William Levak ----- Subject: re: Anyone know what type of plastic Commodore computers are manufactured from? I have looked at the retr0brite website, and gone throgh all the information there. It is my opinion that this procedure has not been adequately tested, and there is a possibility that this procedure may cause long term damage to the plastic. I am a chemist and have some experience testing resins. The retr0brite information mentions a white "bloom" on the plastic from over treatment. This condition is permanent. It also represents chemical damage to the plastic. A common procedure to determine the chemical resistance of polymers, is to put various reactive chemicals on the surface and determine whether, and how much time it takes for noticeable chemical damage to occur. This usually shows up as a white "bloom", but this is not the only damage. Polymers can also suffer damage that is not visible, but causes the polymer to lose its strength and prematurely "age". The retr0brite information says that you should be careful not to over use the chemicals so that the white "bloom" does not occur. But this does not necessarily mean that chemical damage has not occured. If it takes x amount of time to create the white "bloom", then using it for half that time probably means that half the damage has occured. Whether the damage is visible is not the real question here. It would take aging tests to determine whether the plastic is damaged from the retr0brite procedure. I do not see any indication that retr0brite treated plastics have been subjected to aging tests. -------- Original Message -------- >> From: "Stingray" >> Sent: Friday, July 23, 2010 10:37 PM >> Subject: Anyone know what type of plastic Commodore computers are > manufactured from? >> >> Anyone know specifically what plastic the C64 and C64C are manufactured > from? >> >> I have been wondering how to stop plastic Commodore gear from fading. >> I found a really good link on this (also explains why some of the keys >> on your C64C are faded and some aren't). >> http://www.vintagecomputing.co...chives/189 [ this was truncated in the original message for some reason ] >> >> Does anyone have any of their own tips on maintaining plastic >> Commodore equipment? >> >> Regards, >> Stingray >> Message was sent through the cbm-hackers mailing list ----- End of forwarded message from William Levak ----- -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- We shoulda bought a squirrel. -- "Rat Race" --------------------------------

It's mostly been Dazz Dee for me; however, occasionally I have heard or said Dee Ay Ess Dee How about IBM's CKD - always "See Kay Dee"? BTW, did anyone else use CKD (other than PCMs), perhaps RCA (who arguably was a PCM+)? And was the 3390-3 the last CKD DASD? Tom

yet another pdp-11 in fpga

The PDP-11/70 core is now available at OpenCores, see http://opencores.org/project,w11 The documentation is admittedly still rudimentary. The backend handler is still in perl. This and many other things on the TODO list for the future. Walter

Looking for Tektronix 4051 programs...

by clay＠ArcherServices.com

I have been fortunate in acquiring and restoring a Tek 4051 recently. I had used one of these back in '77 to '82 and I still have some documentation, and I found other manuals on bitsavers.org but have not located any software. Do you know of any source on-line? I found references on this site (Feb. 2009) from other users talking about building an archive of software for the 4051. I have keyed in a few short programs to test the vector graphics, but it would be nice to have the original standard pack tape programs. Even printouts would be helpful. I recall when I last used a 4051 back in the early '80's we had the ability to dump & load programs using the serial port, and the ability to un-secret the programs. If I can find this information again I would be glad to provide it to help build a software library for this fantastic system. Thanks, C. Archer

Some application I would assume...? Why not have that application written on your linux system, and run it inside an xterm, and have the application read the data from the serial port, and then output the approriate stuff to control the window? > There's nothing in the manpage (admittedly I haven't read it all, just > grepped it for a few obvious terms) and 'apropos' isn't finding anything > useful.

Any other program that do the same thing works equally well. And I have yet to see any program that works better for this kind of thing than kermit.
