Kennedy 9832 tape drive ( eBay 302562153660)

by cclist＠sydex.com

This one has me scratching my head. eBay Item 302562153660 Sure, it's a Kennedy 9832 drive mounted in some sort of giant hard case. Anyone know if this was a modified drive? What on earth would it be used for? --Chuck

> From: John Welch > Anyway, 'a' comes over as 000141 and 'A' comes over as 000101. Good, the console is working. > CLR > LAD > DEP OK, that loads a '0' (halt) in 0. > CNTRL+INIT > CNTRL+START -> reads 000002 OK, so it reads the HALT at 0 and stops. > CNTRL+BOOT -> Run light is on, SR Disp light is on > CNTRL+HLT reads 173150 Sounds like it may be looping in the high bank of ROM? That's not necessarily wrong. I finally figured out what the ROMs in the M9312 do; the ROMs at 765000 are the first-level diagnostic, and the console. The bootstrap code for the various devices is at 773000. > 773024 LAD, 773000 DEP, BUS ERR light comes on. That makes sense; you can't write to the ROM. > Any suggestions? i) Check the ROM contents; there are two kinds of M9312 console ROMs, one for most CPUs, and one for the 11/60 and 11/70, see the tech manual for the M9312. So read out the first couple of words: CLR 765000 LAD EXAM EXAM etc and let's see what they read. ii) Try starting the console code directly: CLR 765020 LAD CNTRL+START > I have other M9312s I could try. Can't hurt. Noel

APE emulator

by rich.cini＠verizon.net

All ? ??????????????? I can?t remember who contacted me originally about potential enhancements to the APE (Altair Peripheral Emulator) that I have mirrored at ape.classiccmp.net. I heard from Frank Barberis and he mentioned that he?d be willing to make enhancements to the software if there was sufficient interest. ??????????????? So, if we can put together a list of desire enhancement/features I can try to get the ball rolling. Feel free to contact me off-list with ideas. Thanks!

Looking for AMP / TE coaxial connectors - Memorex 651 drive

by mattislind＠gmail.com

Hello! I am about to start with the project to archive disks from the Incoterm system. This system makes use of the Memorex 651 drive which is somewhat odd. It has 64 tracks,is hard sectored with 32 sectors and spins at 375 rpm. But I do have the drive which hopefully still is working. However the interface connector is nothing like I seen on a floppy drive before. https://i.imgur.com/TklddLP.jpg It is a AMP 202515-1 housing. The mating 202516-1 which I need is still in production and available for purchase from Mouser. The small coaxial connectors on the other hand has a minimum order of 1000 units and costs 10 euros each... https://www.mouser.se/ProductDetail/TE-Connectivity/201146-2/?qs=DuOyNqEZh0… Does anyone know of a source selling something like three coaxial connectors like this at decent price? Or maybe a suggestion for another connector that could be modified into fit somehow? Potentially using glue to fixate it. Of course the last resort is to just solder some wires directly onto the drive PCB, but if there is a nice solution I try that first.

> From: John Welch > Any thoughts? Concur 100% with Henk's comments. There is a manual online for the M9312: http://bitsavers.org/pdf/dec/unibus/M9312_TechRef.pdf which will tell you what the other start options are (Appendix C), but see page 3-1, too. Note especially the bit about how the primary dianostics are run before it starts the console emulator; I forget what it does if the primary fails, possibly it halts? Noel

Looking for a book on LAN Manager

by cctalk＠ibm51xx.net

Hello All, I am looking for a copy of: Troubleshooting LAN Manager 2 PDF by Michael Publication date: 10/01/1993 ISBN:155851161X ISBN13: 9781558511613 I've looked the usual areas and can't find a reasonably priced copy. There was one on epay for $10 but the day I marked it to watch suddenly it was no longer available. Interestingly enough the seller has an exact copy w/ the same description/condition relisted for $67 now... Alternatively if anyone has a copy of LAN Manager 2 OS (not just the workstation 3 disk set) w/ manuals that they no longer want I would be happy to take it off of your hands. Thanks Thanks in advance -Ali

Picked up beige Mac G3

by lyokoboy0＠gmail.com

Someone just dropped off a mac g3 at the scrapyard I work at and I picked it up. It has a failing hard drive. Replaced the drive, downloaded and burned a disk with mac os 8 on it, but it refuses to boot to it. How do I go about installing the software on this machine? Not sure if this is the place to ask, but figured it would be worth a shot. Thanks.
