Well, gimme the 822 if it bothers you that much :-). Anyway, it's probably possible to run HP-BASIC on it too but if I had to choose between HP-UX and NetBSD I'd take NetBSD. I do have HP-UX on some machines tough. > But then all that would require is a new crystal, right? There are some conflicting rumors on the 385. Basically HP-UX and NetBSD recognise the machine (380/385) via MMU_ID. This changes if you move one of the wait-state jumpers near the processor (marked 33/25 or something). I have a 25MHz 385.. Anyway, some reports say that a real 385 would be 33MHz and some say 40MHz. > I don't suppose HP have got any hobbyist programme? Not that I know of. You can shell out couple of thousand bucks on 9.1 or contact someone with a lot of different HP-UX versions on CD or 9144 tape. -- jht ----- End forwarded message ----- -- jht

VME532, GNX Unix and want for a Maxtor XT-4175E

by ken＠seefried.com

I need to find a working Maxtor XT-4175E disk drive. I've had the wonderful fortune to have picked up a Heurikon VME532 (NS32532 based) development system. This is probably the fastest single-processor 32532 system produced (Encore MultiMax was of course faster, with more processors). The bonus is that this system is running GNX 3.1 with the National Semiconductor cc compiler, along with a bunch of other development tools (and source code for odd ns32k bits). Unfortunately, I don't have the distribution media, so a disk crash would be fatal, wiping out an almost unique machine. GNX is running on a Maxtor XT-4175E 175MB ESDI drive, and if I could find another one, I should be able to 'dd' a bootable backup. Does anyone on the list have one of these drives that they'd be willing to part with, or knows where I can buy one, in order for me to have a working backup of this system? P.S. - Of course, if someone has GNX distribution media, I'd love to hear >from you! P.P.S. - If anyone has any Heurikon VME532 bits, or GNX knowledge, I'd love to hear from you as well. P.P.P.S. - How long has it been since I ran a Unix (a 32-bit Unix, no less) that could fit, with development system, et. al., on a 175MB drive with room to spare (113MB used). Ken Seefried, CISSP

My IBM 1130

by bakcc＠bigoakhill.com

I've put some new info about the 1130 on the website, like sizes (big) and weights (heavy). Also, I'm accepting offers on it until June 15th. We'll see what happens... (www.bigoakhill.com, click on ForSale). -Bruce Keller P.S. I'll be off-web most of next week, so I won't be able to respond to emails until Friday.

Slicing open the top of a 48T02 Sun Sparc chip to replace b

Your sound like serious ly damaging the top. First you can locate the battery with a small magnet as it's steel/nickel cased. Then grind down the the approximate center and do not grind metal away if you can. then grind to the edges and pry old battery out. I've done a few of these and it's that simple. Making it rocket science is unneeded. FYI the top carries, diode, battery, crystal and two capacitors. Allison

M5903 and M5904 aren't PDP8 boards...they're part of an RH11, a Massbus controller for Unibus-based PDP11 systems. If you plug them into an Omnibus system like a pdp8/e, you'll likely "let the magic smoke out". -Dave McGuire

M5903 and M5904 are MASSBUS terminal and control transceivers, respectivley, probably out of a PDP-11. -- Pete Peter Turnbull Network Manager University of York
