At least in the UK anyway. The recent flurry of DECUS complaints on here
made me wonder what had happened to my own membership - sure enough it
expired last month so they're wanting another 25 english pounds off me.
Thing is, is it still worth it to be a member? I haven't been to the
seminars etc for *years* and don't have a requirement for hobbyist kits or
anything like that......

Ah, I see. It's some whacko custom thingie. Didn't the Lisa originally
use some kind of ProFile-ish thing (custom interface, custom drive

Hm, very interesting! I wonder what model they used? Like I said
most of the early SCSI boards from Adaptec (and most of the other mfr's
as well at that time) were only partial SCSI implementations.
Ah, well, mebbe I stuck my foot in my mouth-- the ST did have a SCSI
interface, didn't it? Or was it yet another whacko custom thingie . .

Just a note from a museum person who stumbled upon your discussion from
March '01...too bad you have this antagonistic attitude - you could
probably share resources with a local museum and do a lot of good. They
would love the information you could provide (and maybe do some public
good with?), and they might have resources (including potential access
to grant money, etc.) that you would also enjoy. It doesn't seem like
them offering someone a tax incentive should be such a problem in that

Ta Sellam - according to my own notes only 10K Lisa 1's were sold, 80K was
roughly the number of Lisa 2/Mac XLs sold......

I'm not really defending museums here, having lost the
local history center to the west coast, but has anyone
at one of these museums ever attempted to defend
their postion by saying "Authentic peroid components only"?
That would rule out new purchases.

Hi Does anyone have any idea of the volts needed for the six pins of the SLT's power point on the laptop
As I would like to get this laptop up and running, It works but i need better way of powering it.

The Lisa's external Profile hard disks (5 and 10MB) and internal
'Widget' hard disks both ran off of a parallel interface. I've not taken my
Profile apart enough to determine exactly what's inside of it but the Lisa
2/10 internal drive certainly appears to have been a custom setup. There
are like 3 circuit boards mounted above the drive assembly itself. I really
should put the effort into getting the Profile working but thought I'd try
to figure out this other setup first.

I'll take the cover off of the SH-204 and report the board ID once I get

If I remember correctly, the ST's interface was close to SCSI, close
enough that ICD created some relatively small interface adapters for it.
I've just been reading "Computer: A History of the
Information Machine", by Martin Campbell-Kelly and WIlliam
Aspray. It mentions the Altair 8800 (on page 240) and
describes the front panel:
When loaded, the program would run; but the only evidence
of its execution was the change in the shifting pattern of
the neon bulbs on the front.
Neon bulbs? Did the Altair really have neon bulbs on the
front panel? I would have expected LEDs -- can anyone
clarify this, please?

Not yet, at any rate. My dad just got a phone from Motorola. Size of an old
(70's) handy-talky, more or less. After some trouble figuring out the
registration, dialing sequence, etc., he managed to phone home with it
(Yes, his initials are BT - no Steven Spielberg puns, please) and there was
a ~ 0.5 second delay between his lips moving and the sound coming out of
the home phone (he was standing on the balcony at the time). Apparently DOD
paid for the system and, to offset part of their cost, is marketing the
hand units (through Worldcom) to the few customers who need communications
where cell phones don't yet go. (Dad's going sailing in the North Sea, then
to a launch site in the Ukraine.) I'm rambling - anyway, Iridium was still
up, as of Sunday night.
How does a PDP-11 boot from an RQDX3 controller?
I have several 11/23's based on the KDF11-AA CPU, which has no on-board boot ROM. The Andromeda UDC11 disk controller that most of these use contains the boot ROM. These machines are in a 4-slot dual-wide card cage which is full. There is the CPU, a memory card, the disk controller, and a serial card.
A couple of these machines are missing the disk controller. RQDX3's seem to be readily available, and there is adequate documentation of the card on the web (jumpers, cable pinouts, etc). Will the KDF11-AA be able to boot from an RQDX3?
If not, can anyone suggest an good alternative?
