DEC 338 Vector Graphics Display emulator.

by charles.unix.pro＠gmail.com

My 338 emulator is working to the point where I can push objects around the screen with the 'light pen'. https://youtu.be/lydGoE-JbIg I am looking for software to test the emulation; I thought that the DECUS kaleidoscope program was available, but all I can find is catalog references. There is a ' 338INSTRUCTIONTEST.BIN' out there, but none of the BIN loaders I have tried recognize it. The PDP-8 versions of space war all use a different graphics system, so are not helpful. Anyone have any 338 diagnostic or applications stashed away somewhere? -- Charles

Here: http://www.ebay.com/itm/252356086401 The starting price doesn't seem wholly unreasonable for what's all there. Noel

I think I replaced it with a 68-pin drive with a 68-pin male - 50-pin male adapter. I'll have to open it up and check. Fortunately I had the original drive carrier to reuse. It also came with a SCSI floppy drive. Don't think I ever got around to testing that.

(Well it was pretty quick from when you mentioned it here.) I had assumed that you came across a hobbyist unit built in the 70's and was repairing or completing it. Sounds like that's incorrect - this is a new build from scratch?, including the printed circuit boards? I had actually wondered from years ago whether the design ever did work reliably, or whether it might be the sort of magazine project where 1 in 100 might function, e.g. say, the memory chips were an iffy proposition as image sensor. Very pleased to see one work. (The one I assembled I had to return to the owner after assembly, we tried it one afternoon with his IMSAI and/or with the scope interface as I recall, but after that it was out of my purview.) >> (I finally get to see an image from a Cyclops camera - never >> did from the one I assembled.) > > Looks even better live.

Getting an ibm as/400

by lyokoboy0＠gmail.com

A local recycling center called me and said they are to pick up an ibm as/400 mainframe from a working environment. I left a deposit and am scheduled to go pick it up in the next day or so. I am not even sure of what all it comes with or what can be run on the machine. Any advice in advance on what to expect? I realize there are a ton of different as/400 models, they were not very descript on the phone, so i have no way of knowing till i go pick it up what exactly it is or what it comes with. I rushed on dropping a deposit on the thing. The other guy at the place is notorious for ripping boards with shiny chips out and trying to pass off the dismantled machine to me. I asked for a picture of the thing on site before it is moved. If it is not all there I am not purchasing it. >From the description it sounds like it comes with some terminals and printers too. could be interesting. Is the guy that put the ibm mainframe in his basement on the list? ive been wanting to talk to him. --Devin

Getting an ibm as/400

by barythrin＠gmail.com

Not sure about mounting the drive and reading the filesystem properly (not much bad could happen from trying) but that gives you the opportunity to back it up (dd) or to potentially hex edit the raw drive itself and overwrite the password hash with one you do know as long as its the exact same amount of characters. (Any different length of characters will shift the data that sectors are looking for ans corrupt the drive). <div>-------- Original message --------</div><div>From: devin davison <lyokoboy0 at gmail.com> </div><div>Date:04/13/2016 10:57 PM (GMT-06:00) </div><div>To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> </div><div>Subject: Re: Getting an ibm as/400 </div><div> </div>The size of two pc towers.

Wow, (that was quick), great job to get one of these working. (I finally get to see an image from a Cyclops camera - never did from the one I assembled.)

Adapters for original SCSI drives to newer drives

by pete＠petelancashire.com

What is a recommended adapter for replacing orig 50 pin SCSI disks with some of the newer surplus SCSI drives ? Here's what I have, I've got a HP 9000/382 without its disk drive, it was pulled to solve the (preconceived) notion of leaking sensitive software. Sadly not only the drive but the carrier. BTW like to see what one of the original carriers looks like Ideas ?

Lost a friend

by dkelvey＠hotmail.com

Sandy Bungarner was a friend that I'd known for 15 or 20 years. He was one of the principle designers of the code that went into Jef Raskin's Canon Cat. He was also a professor a Gavilan College, near Gilroy, Ca. He'd been fighting cancer for more years than I can remember. I suspect not to many knew him but he also loved computers. Dwight
