Lyle Bickley tell story of how Digital Equipment Corporation (DEC) started to make their first Minicomputers.

Having all this digital capability DEC engineers wanted to use the modules to make a computer. Management resisted this for fear of competition from big Blue (IBM). Management finally gave in however the computer could not be called a computer it was called a "Programed Data Processor" or just PDP. The first was the PDP1 soon followed by the PDP8. Folks began calling them minicomputers.
These early PDP computers are in great demand by collectors however it is believed only 3 PDP1's still exist and the only one operational is at the Computer History Museum in Mountain View, California. Later models are available but the very early ones - PDP8, PDP8S are difficult for collectors and computer retro folks to find. I was very fortunate to have acquired several original PDP8, PDP8S and PDP11/70 computers. My interest is more with historical microcomputers. The PDP minicomputers in the "Bugbook Historical Microcomputer Museum" have now been pasted on to other retro collectors of minicomputers. You will some of my past blog posting about these transfers/collectors.

Hi there my name is Daniel J Weasner - I found an old digital Celebris GL 6200 computer out on the street of Welland. Everything is complete in the computer, except for the power supply, and the harddrive. I had an old power supply at my home, and have a couple of harddrives aslo. This computer came with old IBM memory. I have to reflash the bios to get it to post properly !
ReplyDeleteBye for now Danny !
Hi Danny - An interesting place to find a computer - I do know a number of folks have found some good keepers by dumpster diving. A lot of good old junk has been put out for trash. Thank you for the comment and keep looking - Dave
DeleteHi Dave I had a AMD 286 cpu on a I think a socket 7 motherboard in a digital small desktop computer box. The tranformer kick the bucket, and took the AMD 286 along with the motherboard ! Still have the empty DEC computer box, and I am looking for another motherboard for a replacement. I took the old burn out AMD motherboard to the computer store to recycle it !
ReplyDeleteHi I am not sure just what computer you have but sorry to hear it went out on you and hope you find another mother board. Good that you recycled the old mother board. We all need to do more recycling. My wife and I are doing more here at the house. Thank you for reading my Blog. Dave

Hi Ricky - thank you for the nice comment - I hope you can visit our museum in Floyd Virginia sometime. I do enjoy doing these blogs -- they do take me some time to compose but fun. Dave
DeleteMini computers are always an interesting topic for me to read about its information.. I have read about them long time ago.. But your article interested me greatly... Enjoyed Reading thanx...
ReplyDeleteModication being made on the Digital Celebris GL 6200 Computer -- adding 2 USB, 1394 port with a off board interface USB Card--and wiring up a card reader to the front bezel throught the USB Card. Cutting out the small fan hole in front to place a large Arctic Air Fan for better air flow. Rebuilt a tranformer with two fans instead of one. Just got done rewiring the power switch and going to mod the front led lights next to different colour beside boring green. There are many modification that can still be done yet -- like in the computer memory section and maybe CPU even !

Even paint the front bezel flat black for a better cleaner appearance.The front plastic computer bezel could be modified a bit, but not too much.
