Hi,
I have a Grundy Newbrain, which wouldn't start, or if it started it
would only show random chars in the display. I've found out what was
wrong with the machine and if anyone needs help with fixing his (or
hers) machine, I'll be able to point to the problem. As far as I can
tell, this is a common problem with all these machines, and it only gets
worse as time goes by.
Regards,
Torben Ring
Just read some interesting articles of nostalgia on the Warner Qube site on
Yahoo while researching for an article I'm doing over here (England).
I was the first President of Warner Qube system in Pittsburgh which was the
first fully blown QUBE system after the Columbus, and what an experience. I
then went on to Milwaukee and Brooklyn,Queens.
If I can find any of my old info and if you are interested I will dig it out.
( I went on to help develop 2 of the largest U.K. cable/telephone systems for
Comcast as Managing Director of Birmingham England Cable and Comcast Teesside
(England). In each case we supplied cable and telephony service to more
resident than the normal provider (British Telecoms)
Hope this may be of help, if only historically.

Yes, the OS allows entering of drive geometry. Actually only supports MFM up
to 70Meg. RLL drives will of course work, just not to RLL capacity. I'm
looking for the largest drives I can find.

Hmm... those aren't so common (in the DEC world, there are two
choices - the RD53 (Miniscribe 1325) and the RD54 (Maxtor XT2190).
I take it you aren't constrained by a narrow set of expected
geometries? (i.e. - you have a running system and/or the install
procedure asks you about the drive rather than assuming?)

It will work fine with either. In theory, you get slightly higher
coupling losses with 50/125 but can run slightly longer lengths; in
practice it makes little difference. My advice is to stick to one kind
or the other for everything.
York Uni has always used 50/125 for everything (from the original FDDI
and FOIRL through ATM and now 100baseFX and 1000baseSX) -- and we're
smiling now that it's come back into vogue. BTW, stick to ST
connectors where you can. SMAs suck big time, and couplers for STs are
expensive.

Dear Mc Manis
or his Representative
We are a small group of student, who were running
VAX-3300 Computer System, for our research project.
Unfortunately the System has gone out of order. We are
in need of VAX-3300 System to retrieve our data
archived on TK-70 Tape Cartridge.
I have seen your site where from VAX Junks is
available. Micro VAX 3300 (Including SCSI Controller,
RAM more Than16MB, Hard Disk 1GB nor greater and KFQSA
DSSI card worth less than $50. We do not require KFQSA
DSSI card. However following Hardware/Software is also
required to us:
1. Hard Disk RF-30 and RF-31
2. Controller Card for TK-70 Tape Drive (M7559),
3. Interface Card (M7651)
4. Diagnostic Software on TK-70 Tape Cartridge
5.
If you have all or some of these items please inform
me about the availability along with their cost. We
will arrange the shipping and handling for the items.
Your early response would be highly appreciable.
Thanking you.

Hello,
I have many MFM Drives. Not all tested yet but can.
What are they worth.
I saw an old st225 just sell on ebay for 20 bucks or so + shipping.
Make me an offer or what for trade ect.
Oh by the way any body have HDFORMAT.EXE for PCTECH X16B 80186 IBM XT clone
motherboard with 5380 SCSI controller built in. Leading to SMS Omti 5400 SCSI
to MFM
adapter board connected to ST225 5.25 MFM Drive That won't read side 4. Could
boot floppy
and read Directory to find file names in utility subdir.
Need program to low level format MFM on SCSI interface. Bios won't detect
modern SCSI drives. Tried emailing one of designers (written on board) now
works at micron tech. (evolved name of Co.) But no reply.

I don't know if you still have this stuff, but I was the engineer who was
involved in the design of the MegaScan A33400(ITF-3102) VME Interface.
Please let me know if you still have this and if you still need help
answering any questions.
Regards,

That would be very cool and appreciated if someone put the time into
creating such a doc. I have a 2117F and a 2113E that aren't doing much now
that I would like to get doing something more interesting at some point.
Last fall I saw some scrap HP 1000 systems which I believe had the parts to
connect them in a two CPU pair. If I knew more about how to make use of
such a configuration I would consider trying to acquire that hardware.

What do I need to get started with 6502 Assembly on an apple II?
--- I have:
6502 Machine code reference
Apple IIc+
Prodos
Dos 3.3
--- Things I know I need to know:
What call prints a character?
What call gets input of some kind (preferably 1 key at a time)
Any calls to clear the screen?
Any calls to position the cursor?
--- Things I know I need to get:
Assembler
Editor
I don't as yet know how to get things from the web to my Apple II, I
use a Mac mostly to surf
Thanks for the help....
I'm trying to think of all the really old computer companies that are
still in business. GE and Honeywell no longer make computers. DEC and DG
are gone. So there's HP, IBM, Bull... are there any others left from
way-back-when? Oh yeah, there's Siemens. And Amdahl's part of Fujitsu
now. Do they still count? I guess Fujitsu probably counts on its own
merits. Hitachi and Toshiba left the industry recently, after many years.
And then there's Unisys, with their recent turn to weird hybrid systems.
Did I miss anyone?
Peace... Sridhar
