Hello.
I have a Commodore "new" D9090. I am experiencing some symptoms that I
hope someone can help me diagnose. I don't have the manual for the
D9090. I have verified that everything is plugged in, but I have not done
any electrical tests. The drive was working earlier this month and then
was shipped to me. When I received the drive initially it did not work at
all, but pressing lightly on some of the socketed chips to be sure they are
making proper contact got me at least to the point I am now. It appears
that the package was dropped or vibrated during shipping.
I leave the unit powered up for a good ten minutes before turning on my
known-to-work Commodore B128. The expected drive initialization lights
flash and the system sits waiting for action while the top light shines
green, the bottom light is off. Here are the things I have tried:
-------------------------
?ds$ - returns CBM DOS 3, etc. message
-------------------------
open 15,8,15
print#15,"i0" [top and bottom lights shine green, drive sounds spinning,
never completes.]
close 15
NOTE: The first time I run these commands the READY prompt returns to the
screen and I can continue working, even though the drive lights perpetually
shine green and the drive spins. If I do repeat this set of commands
however I will freeze up the computer and I am forced to hard boot the B128.
-------------------------
header "degnan9090", d0, i01
The "are you sure?" message appears and I can initiate the drive
format. Both lights shine green. The B128 freezes up. Because I have a
Rev B ROM, I expect that it will take less than 3 hours to format the
drive. In my testing I finally aborted after 10 hours. I know from
experience that when a header command is issued, control returns to the
B128 (or whatever computer) while the formatting is happening on the drive.
-------------------------
dcleard0 - does not appear to move the drive heads.
-------------------------
It seems like the heads are not moving and that's the problem. I do not
hear "head moving noises"
Any suggestions?

here are some pics:
I have a scanned copy of the DECsystem-10 reference card on my web site.
I put it up there for someone to grab and I don't have enough diskspace
on my site to leave it up (and it is not in bitsavers.org's format, so
they don't want it). I'll be deleting it from my website in about a
week. If anyone wants it, grab it while you can.

about 1.5M.

This is a note to owners of the Telenex / Atlantic Research 'Interview' 7000 and 8000 series datascopes (sometimes known as serial data analyzers), particularly the 7000, 8700 Turbo, and 8800 Turbo series.
I've been fortunate(?) enough to acquire a large stash (over a dozen) of the 8700's and 8800's. I'm in the process of archiving their EPROM and disk images even as I type this. I'm also experimenting with interchanging parts, just to see what happens and to see if a lower-end unit can be upgraded by putting a different set of EPROMs or a backplane PAL in place.
I've been reliably informed that one of the units was a sales demo model, and had every possible option enabled in the software. I'm pretty sure I already archived it. I've also archived, among other things, the updated EPROMs necessary for the disk controller board to handle large SCSI drives (850MB at least).
If anyone has one of these grand old beasties, and wants to resuscitate it or maybe upgrade it a bit, drop me a note. I can't promise I'll be able to help, but I may just have an answer or component that you need.
Keep the peace(es).

The GoldenGate II bridge card, I have one I got as 'scrap' but
all the socketed (PAL) chips were pulled.
Unfortunately the GoldenGate II lacks one signal needed to run
some 16 bit cards in 16 bit mode so cards like 3Com 3C5x9xx
won't work properly.

If anyone has a working floppy drive they'd be willing

Thanks!

I have an old NEC 3FGx monitor with very little use (belonged to my
parents who were not "computer people") that had a beautiful clear
picture until recently. There's probably a bad electrolytic cap
somewhere, since it now has horizontal problems (small dim display,
lack of horiz sync) until it is left on for 20-30 minutes.
Can anyone point me to a schematic to make it easier to repair without
"shotgunning" caps blindly?
thanks

I was just given an IBM AS400/9040 at the computer refurb/recycling shop I operate. Is there anything legitimate that it could be used for, or should I scrap it? I know nothing about it other than that it's big and heavy, and it seems to IPL according to the front-panel display. I'm going to try to hook a terminal to it, but I'm not sure how quite yet.
Hi.
I'm looking for the chassis to a PS/2 Model 95A server. I don't need
the motherboard, just the chassis and power supply, complete with the
front panel display and drive bay covers.
Anyone know where I might be able to get one for not too much money?
Peace... Sridar
I have some sort of web browsing software cd for the
Dreamcast if anyone has a need for it.

The 800k format is very proprietary, I'd be surprised if there was any way that stock IBM hardware could write it, no matter what the programming tricks were. More data was packed on the outer tracks than the inner tracks (done so that they didn't have to change the Lisa ROMs (expecting 400k single-sided) according to rumor). The 1.44s can be done on any machine that has DD or RAWRITE or anything similar, provided that it also has a 1.44 MB mechanism. All '030+ macs have SuperDrives, as do SE-FDHD, LC, and "upgraded" IIs with the IIx ROMs (fair number of upgrades were sold by Apple).
For an OS, I'd use either 6.0.8 (very fast, can turn MultiFinder off, "classic" look but won't do Virtual Memory or 32-bit addressing (max memory=8MB, everything else is ignored)) or 7.1 PRO (fastish, and you can patch in much of the stuff that's nice in 7.5/7.6). If you're running 7, be sure to get Mode32, available free+legal. ROMs from the pre-IIci era aren't fully 32-bit, so they have problems if you turn on 32-bit addressing. A/UX also runs on the SE/30, it's the only compact Mac that can run it. For these old beasts, assuming that you aren't going to be a heavy Photoshop/PageMaker user, 16-20 MB of RAM works just fine with 7.1. System 6 won't see anything over 8. Remember to get your long-blade Torx-15 and case cracker, and to unplug SCSI, power, etc. before trying to slide out the logic board.
Scott Quinn (SE(6.0.8), II (6.0.8), IIci (7.1), Quadra 950 (pegasys, A/UX 3.1), Quadra 700 (7.6)).
P.S. The LC is weird because of several things: 020 but no PMMU option, 16-bit data bus, only will run up to 10MB RAM and 1/3 ht HDD, funky nonstandard video that doesn't run on all monitors. The only excuse I can think of for Apple was that they didn't want to eclipse the II in power. The 24-bit addressing bug in ROM I can find no excuse for- the 68000 was designed with a 32-bit outside address bus successor in mind (full internal 32-bit registers)- they must have just been lazy.
