Multiple IBM System/23 Datamasters, and more, available in upstate NY

by tosteve＠yahoo.com

Adam sent me this information, contact him below if interested in these "rare and valuable" systems: ================================================================================================ I have come across the following IBM system/23 models in good condition. They were covered and stored in a clean attic since the mid-late 80's. (1) 5322 - all-in-computer (2) 5324 - modular computer (2) 5242 - printer (1) 5247 - external disk storage (2) terminals - ??? We will probably store these until summer 2015 if we can't find a good home for them they might end up junked.

PDP-8 for sale

by jnc＠mercury.lcs.mit.edu

So there's a PDP-8 for sale on eBay, and it's not up with a stupidly massive BiN number, but an actual auction with a reasonable start price: http://www.ebay.com/itm/231424380705 8's aren't my thing, but I'm sure someone here would be interested in this... Noel

PDP-8 For Sale

I wonder if the latter is on somebody's wall :-( > > -tony I think he's just quoting the card numbers from the handles. Looks as though the whole (3-card) stack is there OK. Bob

Weekly Classic Computer Trivia Question (20141215)

by dpi＠dustyoldcomputers.com

OK, so somewhat weekly questions. Back in the days of high speed line printers there was a characteristic of drum style printers that made the output print style quite distinct. What was this characteristic? I don't miss the noise of those devices and it seemed like no matter how careful you were when changing the ribbon you would smudge your hands. Doug Ingraham

Strange Problem on DECstation 2100

by robert.jarratt＠ntlworld.com

I have been trying to get my 2100 working. I have been using MOP to boot the machine and try to install Ultrix, although this is not working for some other reason at the moment. Until this morning, it was booting from MOP just fine, but now it, after leaving the machine overnight and not doing anything to it, I get this when I try to MOP boot: Ultrixload - V4.5 Thu Sep 14 07:07:53 EDT 1995 Excptn: (vtr=NRML) Excptn pc: 0x807001f8 Creg: 0x30000010(CE=3,EXC=RADE) Sreg: 0x30000000(CU1,CU0,IPL=8) Vaddr: 0xaaaaaafe Sp: 0xa13fbba8 0xa13fbba8 : 0xaaaaaaaa 0x80701310 0xa0003b60 0x80700000 0xa13fbbb8 : 0xaaaaaaaa 0xaaaaaaaa 0xaaaaaaaa 0xaaaaaaaa 0xa13fbbc8 : 0xaaaaaaaa 0xaaaaaaaa 0xaaaaaaaa 0xaaaaaaaa 0xa13fbbd8 : 0xaaaaaaaa 0x80700048 0xa00039c8 0xaaaaaaaa 0xa13fbbe8 : 0xaaaaaaaa 0xaaaaaaaa 0xaaaaaaaa 0x00000000 0xa13fbbf8 : 0xaaaaaaaa 0xaaaaaaaa 0x00000001 0xa00039c8 exit(-1) The really strange thing is that if I attach a CD-ROM drive and boot off that first, then try the MOP boot after that, the MOP boot works! Before anyone asks, I have other problems which mean it won't successfully install Ultrix from the CD-ROM, and I am trying the MOP route because of this. The CD-ROM problem is something to do with the block size, I know about the block size jumper and have tried with the jumper installed and removed. I have a workaround which is to connect the CD-ROM, boot off the CD-ROM, let the CD-ROM installation fail, then unplug power from the CD-ROM and boot >from MOP. But that is horrible, and wasn't necessary until this morning. Any ideas? Regards Rob

Need HVPS for old Laserjet IIp printer

by charlesmorris800＠centurytel.net

I?m trying to find the high voltage power supply board for my old LaserJet IIp+ printer. Several places claim to sell them, but as soon as you order, within a day or two, they are mysteriously ?out of stock, sorry for the error?. A good used one would be fine. thanks for any help. -Charles

Wanted: SIMH VAX VMS tape image tester, take 2

by cclist＠sydex.com

Okay, I think I've gotten the SIMH image thing straightened out--and I've added a descriptive record after the EOM marker in the image. Just like a regular tape block; i.e. 32-bit little-endian length before and after the description. To retrieve, just to to the end of the file, read the last 4 bytes as a record length and then back up and read that much. Same contents, FORTRAN 4.5; if anyone is interested, I have what appears to be the 4.6 tape as well. Attached file link follows. I've linked 1 file to this email: * SAMPLE1.ZIP (345 KB) hosted on Box: https://app.box.com/s/hjamwz80ettlmr1kjsx8 As always, thanks much. --Chuck
