Ok, so thanks to Don Maslin who sent me an NEC APC system disk and a bit of luck I have finally been able to boot my NEC APC. I believe the drive heads were dirty, but constant running of the disk in the drive finally scraped away enough grime to make it read (couldn't find an 8" head cleaning disk...must organize warehouse; drives are enclosed and I couldn't seem to extract them from the machine to clean with alcohol...oh well). I stuck the disks I'm trying to recover data from in the B: drive and did a DIR but they all come back with "NO FILE". Now of course this means that the disks contain no files but I'm thinking there has to be something wrong here. The system disk is CP/M-86. I still don't know what format the disks in question are but I assumed they were also CP/M-86. What could be amiss here, aside from the possibility that the disks ARE empty? What utilities are available to me on the system disk to view a raw dump of the target disks? I can't believe after all this effort that these damn disks contain nothing. As always, any help or suggestions would be greatly appreciated, and please reply directly to sellam(a)vintage.org. Thanks!

Graphics card

by rmeenaks＠olf.com

Hi, I picked up a graphics card when I was down in Germany last week. It contains several SMB-type connectors labeled as follows: EX - What is this? VS - Vertical Sync CS - Composite (or Horizontal) Sync R - Red G - Green B - Blue What is EX?? I was planning on using the BNC-to-VGA connector which has 5 BNC connectors for VS, CS, R, G, and B but I dont know what the EX is used for... Ram

Somewhat OT: Then & Now.

by netsurfer_x1＠hotmail.com

This is something that I had posted on the comp.sys.cbm newsgroup that I thought would be intresting to see how much the computer world has (or hasn't) changed starting right around 1980 or so. So if you've seen this before, I apologize. Anyway, here are some things that have changed (or have they?) in the computer world: Back then we had: Daisychained peripherals to the Commodore IEC serial bus. Now we have: Daisychained peripherals to the Universal Serial Bus. Back then we had: The Original Macintosh. Now we have: The iMac. Back then we had: Computers with a built-in RF modulator. Now we have: Video cards with a built-in RF modluator. Back then we had: The Original Macintosh II. Now we have: The G3/G4 PowerMac. Back then we had: The Commodore 1581 head-knocking/Click of Death problem. Now we have: The Iomega Zip drives' Click of Death problem. Back then we had: The Macintosh Portable. Now we have: The iMac. Back then we had: The Tandy Model 100. Now we have: The PalmPilot. This is all that I could think of, I want anybody who can think of anything that hasn't changed to add something on this list. Let's show people that the old phrase "The more things change, the more things stay the same" is true! ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.

Link update please

by dastar＠siconic.com

I need to update my link for the old ClassicCmp archive that Kevan Heydon had on his site. I remember there being some talk about moving this but I guess I failed to update my link. If someone could e-mail it to me at sellam(a)vintage.org I'd appreciate it very much.

You can order the "i960 Microprocessor Electronic Library" CD-ROM from Intel's literature centre. The order number is 272743-002. Or look on the Intel web site. -- Mark

IBM 3725 In Central Illinois

--- Dan Linder <dlinder(a)uiuc.edu> wrote: > List, > > There is an IBM 3725 available... Just a large heavy blue computer. > I'm also quite interested in what it is. It is big, it is heavy, it is blue, but it isn't a computer. It's a PU (Physical Unit) Type 4 as seen from an SNA network standpoint, and is more commonly known as an FEP (Front End Processor) - Think of it as the I/O interface for a mainframe. This is the thing that a 3274 would talk to - that box we were discussing here a few days ago. The CPU is a PU Type 5, the 37x5 is the PU Type 4, the 3274 is a PU Type 2 and they all coexist happily in their own roles on an SNA network. Each PU Type can initiate or resond to certain types of network traffic; it's very hierarchical and structured. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

Mike also got a Motorola National did the BLC80xx series if memory serves, decent intel compatable multibus. Slightly surprized to see a ISBC80/20 cpu as they nominally had National cards. I think I have the manual for the BLC80204 8080 card that was the national equivelent of the ISBC8020. Allison

SIMM Remover tool

by technoid＠cheta.net

My Sparcstation 330 has 24ea 30-pin simms onboard. Removing them was a problem for me when I was diagnosing bad ram. I found that a 7.65x54mm cartridge for my 100+ year old Argentine Mauser rifle was the perfect tool for working with this type of simm socket. I suspect any full-metal-jacket round with a "Spitzer"-type nose (pointy) will work such as 7.62x39 Warsaw Pact or 5.56 Nato will work just as well or better. The trick is to start with the 'lowest' simm - the one that is 'under' all the others. Insert the nose of the round into the hole on one side of the simm, press down to disengage the clip on the socket and lever against the simm 'below' the one you are removing. The last simm is more difficult because there is no simm 'beneath' it to lever against but the tool is still helpful. Especially if your video card is like mine, piggybacked onto the motherboard. I lever against it for the last simm. The copper jacket is soft and will scratch but does not appear to shed material which is good because copper is conductive.... These minor scratches will affect accuracy when the round is fired so don't use this 'tool' as ammunition in a competition! Yes. I drew a five-shot, one-hole group at 110yards with my Winchester 30-30 rifle over open-sites one day. Can hit a quarter at 300yd with a scope..... As with all explosives, due care is indicated.....
