The DG terminal I am looking for is the one pictured at this URL. Can someone tell me what model it is for sure? http://www.simulogics.com/museum/N4_1.JPG Thanks! Jay West

[ot] anyone experienced with ibm personal power series 830?

by trash_tmp＠poczta.onet.pl

some time ago i found a mainboard from IBM Personal Power Systems 830. it's a PReP (or CHRP, i'm not sure) from about 1995[1]. i don't have a parity SIMMs and a cache module, that this machine was originally equipped with. yesterday it was working fine. well, almost - i couldn't figure out how to make it boot netbsd, it got hang after loading the image, however it could load SMS and pass all the test without problems. nevermind. one of things i tried was to update firmware to the latest (v1.10, from p8x0_110.exe, downloaded from ibm ftp site) version. now, during boot, when displaying the memory icon it makes a short beep and hangs, w/o any error icon. can anybody experienced with this hardware tell me, what should i do now? i guess nobody at ibm tested it without parity memory and without l2 cache module. should i get parity simm's, or a good soldering iron and memory flasher? silly me. before updating, i got into a firmware command line and made it load new firmware into memory and jump to it's entry point. it hanged in the exact same way it does now, except it showed an 'error 00020000' icon. i thought, 'well, it tries to reinit some device that does not like it'... and flashed the verified-not-to-work firmware into rom. [1]. so, strictly speaking, it's offtopic here. it wasn't too popular, however, and this is the most appropriate mailing list i found.

I believe this machine used an acoustic delay-line memory. A very nice piece of history. Item number: 2762297741 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2762297741&category=1247… --Bill

VCF 6.0 in 3D

by rivie＠ridgenet.net

I've posted the pictures I took at VCF 6.0 over at http://anachronda.webhop.org/~rivie/VCF6.0/ They're primarily of the Computer History Museum's collection because I like to take 3D pictures. Since I don't have a 3D camera, this involves taking two pictures, one while leaning slightly each way. People tend to move between shots, so pictures of crowded areas don't work out too well. Two view the 3D, you need to be able to either cross your eyes or make them parallel while focussing independently. If you were able to see those Magic Eye 3D art thingies that were popular a few years ago, you can do the latter; the rightmost pair of each 3D group is for you. If you cross your eyes (like me), you'll want to look at the leftmost pair. Maybe I'll be able to put together some sort of exhibit for VCF7.0 so I can have access to the exhibit area before it gets crowded... -- Roger Ivie rivie(a)ridgenet.net
