I've started messing around with a GRiDPAD 1910 I
got a couple of years ago. Works fine on AC using
the brick that came with it, but the two battery
packs I got with it are dead. They won't take a
charge, either in the machine or connected directly
to the brick (they have a socket for this). The specs
printed on the batteries list 12 volts, 1Ah. I opened
one of the packs and the contents look very much like
10 AA batteries.
I'm wondering if I can replace the contents of the
battery pack with 10 AAs. The specs printed on the AC
brick say it produces 17.25 volts at 2A. If I replace
the contents of the battery pack with 10 AAs, I figure
I'll get around 15 volts. Anybody want to hazard a
guess as to whether this will work?
Thanks,
Bill Sudbrink
Bob,
I don't know how far it is from Chicago but I used to go to the DRMO salvage sale at Wright Patterson Air Force Base in Dayton, Ohio. Its been a while since I have been to one but there used to be some good stuff that used to go through that sale.

The likelihood of someone having six Apple 1s is similar to that of
having an i432 dev system, the original 4004 mask set, an ibm 5100
proto, an EDSAC1, or a shrinkwrapped Cray-1. Or even possibly Steve
Wozniak (hopefully in shrinkwrap) etc etc etc.

Ok, I'm going to close the list for the 1802s for now. Here are the
people I have. If you sent me email about this and I've missed you, let
me know.

I'll be in touch with each of you individually by email to confirm
that you still want the parts and exchange shipping addresses and so
forth. I think that personal checks will probably be the easiest thing
for me to handle at this point. Some of you have suggested PayPal, and
I'll probably look into that in the future, but if I try to set that up
right now it'll just delay things further. Sorry I'm not real quick
about all this -- I can do real preemptive multitasking, but I've only
got an 8-bit data bus to work with, and I have to keep swapping these
clunky 8K blocks in and out of my 16-bit address space. Besides, I've
got to do all this to the tune of a 1.87 Mhz clock. But I _do_ have a
hardware MUL! That's all to say that I'll get it all done, but it may
take me a while. If any of you have a real good reason to want to get
some chips fast, let me know and I'll push you on the stack last.

Ineed it was. It was also about one version behind and
contained many heath specific drivers such as the DX/DY
driver for the floppy. It did run all version of DEC
RT-11 as the floppy had a RX01 compatability mode. The
serial cards were DL compatable and the punch was PC04
compatable.

I believe the HT-11 distributed by Heath was a modified version
of RT-11, but standard RT-11 did and does work on the H-11.

Ram,
Great ! Let me know when you find it and I'll send you postage and some blank tapes. I should have checked with the list first.
BTW the sun workstations are going out today priority. Thanks for your patience.
Brian.
Hi Brian
I have a copy of it but the problem is I dont know where I put it :-(
Also, I missed a couple of minutes from some of the series (I believe
the last one), but other than that, it is a great series. I am currently
moving
so most of the stuff is boxed up. Once I finish moving, I can make a copy
for
you.
Ram
PS: Still waiting for the SUN :-)

For those who are griping about the drive, Worcester does have a small
airport. Many commuter shuttles and smaller commercial aircraft fly in and
out on a regular basis. Hotels abound in Worcester as well...
By the way, do I get any points for suggesting Worcester? :-)

Does anyone have a copy or know where to purchase the video series "The machine that changed the world" that was produced by WGBH for Nova? I remember recording it years ago but have since misplaced it. It hasn't been available for purchase for a while as I understand.

Today I picked up a Hayes Transet 1000, and I don't know anything about
it! It comes in the classic Hayes extruded aluminum case with black
plastic caps on either end. It is one of the older products as it uses
the 13.5vac wall-wart.
The panel at the user end has 8 LED indicators and 3 pushbutton
switches. The indicators are numbered and identified from left to right
as listed below:
1 PWR
2 RDY
3 MRK
4 RPY
5 A
6 B
7 C
8 D
The switches are lettered and identified as follow:
X SELECT
Y MARK
Z REPLAY
At the 'business' end there are three D-sub connectors in assition to
the 3-pin AC power connector. The D-subs are as follow:
15s PORT P1
9p PORT S1
9s PORT S2
Does anyone have any information about this critter - better yet,
documentation - or ever used one?
Thanks!

Too right - plus I've already listed mine in a Netscape and aIEeeee friendly
way, and I'm working on making it Lynx friendly for Tony :) (BTW Tony, I
*will* post your MicroProfessor!)
It's always fun when you get mentioned in a national Computer paper!
Anyway, its at www.binarydinosaurs.co.uk and as of today I've added an Atari
Lynx (bought only because it had a DOOM cart :o) and a Sinclair Scientific
Calculator with leatherette case, power pack in case and programming
cards......I wasn't chuffed at all! Not bad for 5 english pounds. Other
machines coming soon are an unboxed Camputers Lynx 96, and hopefully a boxed
one if my price is accepted.......they're like buses these things - wait 2
years then 2 come along at once :o)
Happy Easter, people. I'm on holiday next week so I'll sub up from home.
