I recently picked up an SGI Personal Iris 4D/35 and I'm struggling to
get IRIX installed and working (with emphasis on "working").
I currently have at my disposal a copy of IRIX 4.0.5 and a copy of IRIX
5.3. I've tried installing both, and the installation succeeds in both
cases, but neither installation works after install.
The symptoms are:
IRIX 4.0.5 installs. On reboot I get the typical chatter in the console
window (UNIX banners, fsck, "The system is coming up," etc.) after which
the screen goes black and stays that way forever and ever. Nothing I do
causes any response from the machine.
IRIX 5.3 installs. On reboot I get the same chatter as above, after
which the screen goes black, except with a red SGI-shaped mouse cursor
which I can move around with the mouse. After about 5 seconds the
screen turns light blue (the same light blue as the console screen at
power-on). At this point I can hit esc to bring up the console, and
the characters I type on the keyboard are echoed to it but nothing I do
has any effect.
Any suggestions?
I'm also looking for earlier versions of IRIX to run on this machine --
any good places to find them?
Thanks!

I have scored a few nice items this day, a PET 2001-8k with
lots of extra's like a lightpen, a sort of digitiser keypad,
an large expansion board which contains a compuware floppy
interface, a compuware dual floppy drive, about 3 dozen tapes,
4 boxes with floppies and a heavy Centronics printer.
Also a little gadget which allows me to select 3 different
character roms using a little switch.
And the best of all is that the machine works and the keyboard
just looks as new :) and that all for a bargain price of just
100 Euro's ($128).

I saw your site on the web re; Saic V2-LC portable computers. I have one (without a hard drive) and the PIN # is:
56357. Can you tell me what CPU processor this would be?
Thanks

Those parts are for the Clock, PLL, and write timing. They do not alter
spindle speed as thats the job of the floppy. FYI the 1.2mb floppy appeard
about 6 years after that board was sold.
If you doing 1.2mb 5.25 (or any 8" format) then you DO NOT change those parts.
If you want the conventional 360k two sided (40 track 2S DD) or 720k (80
track 2S DD) then you have to.
Those parts changes are why there was a Disk1A.

Ah, it's using the definitive PC FDC. It was developed well before
PCs standardized. PCs however don't offer much choice and if they did
keep all the FDC features you could put a 8" on a PC and read SSSD!

If that were the only horror it would be ok. It's pretty poor but it was
one of the first controller chip that was 8bit and low chip count. The
8048/9 was vastly better!

Does anyone know if this is a real working PDP-1 or a mocked up, emulated
thingy?
Might be interesting for the games nostalgia for those (like me) whose
classic computing interest overlaps to classic gaming.

I found a scrapped box today at work :
2 8" floppydrives , RS232 and printer interfaces. Internally an F8
chipset ( F3850 / F3852 / F3854) with a WD1771 fdc.
Strangely enough a set of floppies lay on top, labeled Cp/M, Basic CP/m
Pascal etc.
Was there ever a CP/M version for the F8 ??

The one I am currently using is Japanese one
and they (like the USA?) have 2 pin plugs into
the mains, whereas our (UK) plugs have 3 pins
so I can't use a UK power supply on a Japanese
one.
Like I stated in another post (I think?) I got
a replacement off eBay which I received today,
so all is well again.

I recently got this card in and have no idea who made it.
Anybody have an idea of what it is (I browsed through th99 with no luck, and google didn't help much either)?
Pictures:
http://home.neo.rr.com/unknownk/images/100_0897.jpg (the cable with in/out that goes on the end).
http://home.neo.rr.com/unknownk/images/100_0896.jpg (The card itself)
The main card is LV-007 and the TV tuner part is LV-008
Major chips are CHIPS F82C9001, Phillips Saa 7151B, Phillips 9065.
I am pretty sure it is a video capture/TV tuner card but I need to find out who made it to find drivers. The cable on top would be to connect to a VGA card I would think, but it looks like it also has VGA cable to put inline with VGA output (redundant?). The little connector on the bezel side bottom looks like a mini headphone jack.
The card came a little bent (they used a padded mailer and not a box for shipping) and EC4 is gone (but not found in the mailer, you can see what's left of the cap pins floating in air above and to the right of the 24.576 oscillator top middle of the card), wonder if that cap is even needed.
Any ideas?

Perhaps "abomination" would be a less-charged word...
certainly applicable in this case.
