Beschreibung: Der NEC Pc-8201a war produziertes Beginnen 1983 und war Version NEC der Kyocera-Familie der Laptop-Computer, die das Modell Tandy 100, 102 und 200 umfaßten. Er basierte auf der CPU 80c85, hatte eine 8 Linie, den LCD-Schirm mit 40 Spalten, versendet mit 16k von RAM und würde fast 20 Stunden lang auf 4 ' AA-' Zellenbatterien laufen. Energie könnte mit einem Adapter 6-Volt A/C auch zur Verfügung gestellt werden und sie hatte Drucker, Serie, Kassette, 2-sio, Wechselstrom und Barcodelesertore auf der Rückseite. Es gab auch ein Expansionstor auf der Seite, die im Allgemeinen für externes RAM-Aufsteigen, sowie eine Sekundär-ROM-Einfaßung benutzt wurde, die für zusätzliche Programme, um die Microsoft-BASIC vorhanden ist, den TEXT (einfachen Textherausgeber) und die TELEKOMMUNIKATION (Kommunikationsprogramm) zu ergänzen die mit der Maschine versendete. Wegen ihrer kleinen Größe, weniger als 5 Pfund und kleiner als eine Mappe 3-ring und die Tatsache, die sie laufen lassen würden, also lang auf bereitwillig vorhandenen ' AA-' Batterien, waren die Kyocera-Familienlaptops sehr populär unter Jounalist und so. Sie hatten auch die Eigenschaft des Habens des Batterie unterstützten RAM falls vom Batterieausfall, eine kleine Nickelbatterie, die um diesem kümmert. Die Nickelbatterie wird von den ' AA-' Batterien oder VOM A-/c Adapter neugeladen, wenn die Maschine nicht innen Gebrauch ist. Das Pc-8201a konnte zu 128k von RAM auch aufnehmen Patronen durch es verwendend ist externer Expansionsschlitz und kennzeichnete auch einen redefinable Schirmzeichensatz. Obwohl die Maschine 32k von RAM nur direkt zugänglich machen könnte, war sie bis bis 64k von RAM und zu 64k von ROM innerlich expandierbar. Im Fall vom RAM, gestand das System Ihnen Bank-Schalter zwischen den zwei Klumpen 32k zu und im Wesentlichen gab Ihnen zwei Seperatemaschinen mit Seperatedaten-Speicherbereichen. Peripherie wie helle Wands, Thermal-Drucker, Laufwerke, RAM-Expansionspatronen und Videomonitorschnittstellen waren auch für die Maschine vorhanden. PCM-Zeitschrift druckte auf einmal Programme für diese Maschinen, meistens für das Modell 100 Tandy, in Form von Barcodes, die der Benutzer dann in den Computer ablichtete. Ein Buch, das "Erforschen des NEC PC-8201a", geschrieben von Marvin Malloy genannt wurde, war auf einmal vorhanden, obwohl es aus Druck heraus lang ist. Diese frühen Laptops wurden von den Maschinen wie dem Tandy 600 und Epson Px-8 gefolgt. Das Px-8 hatte einen Schirm mit 80 Spalten, eingebautes Bandlaufwerk, 64k von RAM und ließ das Betriebssystem CP/M laufen. Das Px-8 wurde 1984 eingeführt. Diese bestimmte Maschine ist zu 64k von RAM innerlich erweitert worden, obwohl sie gerade es ist ursprüngliches Programm-ROM ohne die zusätzlichen addierten Anwendungen behält. Sie schließt auch die ursprünglichen Handbücher, das externe Modem 300bps, den Thermal-Drucker mit 40 Spalten, der auch die angetriebene Batterie ist, und das weiche slipcase mit ein. Der bewegliche Thermal-Drucker mit 40 Spalten ist ungefähr die Größe eines Kastens von 10 3-1/2 "Disketten und schließt hinter dem Pc-8201a über ein 26-Stiftbandkabel an. Datenspeicher ist über einen Standardkassettenrecorder, angeschlossen an das CMT-Tor des Computers mit einem speziellen Kabel.

Introduction:

This FAQ is provided to help owners or users of the NEC
pre-MSDOS model PC8201a and PC8300 portable computers. All
information is as accurate as I could make it. However no
guarantee is made that this information is 100% accurate. It is
based on 9 years experience with the model PC8201a, old
magazines, and notes taken through the years. For the rest of
this FAQ the PC8201a will be referred to as the 82 and the
PC8300 as the 83. Please send me any corrections, updates, or
technical information at my E-mail address above.


Q. What is an NEC PC8201a or PC8300?

A. In 1983 Kyoto Ceramics, Kyocera, started manufacture of a
series of light weight battery powered computers based on
Complementary Metal Oxide Semiconductor (CMOS) microprocessor
called the 80c85. There were eight variations produced under
four brand names. Seven were built by Kyocera and one by Nec.
All were available in the United States and other parts of the
world at various times. The 82 and 83 were the NEC variants.


All eight variants shared certain features:

- Powered by 4 AA batteries or optionally by a 6 volt AC adapter.
- Screen display 40 characters wide on an LCD screen.
- Size of a three ring notebook.
- Text editor (TEXT), BASIC programming language (BASIC), and
telecommunications (TELCOM) software permanently in ROM.
- Ability to take programs on an optional ROM socket.
- Memory could be expanded.
- Full size keyboard.
- Minimum of 8k RAM installed for programs and files. (Most had
more)
- Weight under 5 pounds.
- Could save and load programs and data from a cassette recorder
with a special cable.
- Simple text based point and shoot interface. Sort of a text
Macintosh.

Q. What are the STAT settings?

A. The STAT settings are the way you configure the COM or
communications port on an 82 or 83. The six digits break
down as follows.
|------Baud Rate
||---Parity
|||--Word length
||||-Stop Bits
8N81XS
||-SI/SO flow control
|-Xon/Xoff flow control

Baud rate: 1=75 2=110 3=300 4=600 5=1200 6=2400 7=4800 8=9600
Parity: N=None E=Equal O=Odd I=Ignore


Q. Where can I get online support for the 82 and 83?

A. On the Internet there are two newsgroups where you can post
questions. The first is comp.sys.laptops and the second is
comp.sys.tandy. The tandy newsgroup has many participants who
have old magazines, etc. and who sometimes answer posted
questions.

If you are on America Online there is a support area run by NEC.
It has a message board that has a topic area for older and no
longer supported portable NEC computers.

If you are on Compuserve there are archives in the Tandy area
that include text files and programs for the Model 100. There
are also files on how to use these on an NEC. There are some
files specifically for the NEC machines.

If you are on GEnie there are archives in the Tandy Roundtable
that include text files and programs for the 82 and 83, the
kc85, the Olivettis, and the Model 100. There are also files on
how to use the Model 100 files on an NEC.

I do not know what the status is on Delphi or Prodigy, but if
you are members there it won't hurt to look.

NEC also has a technical support BBS at (508) 635-4706. I do not
believe they have any files for the 82 or 83, but they
_might_ answer questions.

Club 100 is a BBS in California that also sells some accessories
that fit the 82 and 83. They charge for membership and have some
files for the 82 and 83. The phone number is (510) 939-1246. See
below on the vendor list for mailing address. Their _consignment_
area often has a lot for the 82 and 83, but you must scroll through
all of it. One thing they have is back issues of Portable 100
and Pico magazines, which are a gold mine of information. They also
produce some products for the 82 and 83. They were still operting
as of late September of this year.

The Daily Planet BBS offers both files for these machines and is
a contact for Daniel Cohen, a dealer who supports these machines.
The BBS number is (808) 572-4856 or 7. The BBS is free. Daniel
responded to E-mail on his system in thelast couple of weeks and
confirms he has some parts for the 82 and 83 as well as produces a
custom ROM for some models. Daniel has had praise from acquaintances
who have dealt with him.


Q. Can I get a manual anywhere?

A. NEC parts used to have manuals. They ran about with
shipping. Last person I know of who ordered one, was still able
to get one in early 1993. Please let me know if you get one.

If you you can't find a manual, about 90% of the operations of
the 82 and 75% of the 83 were identical with the same areas on
a Tandy Model 100/102. Old books on those machines should help.
Pinouts of the ports are available by E-mail from me at my
address below.

Also Marvin Mally wrote a book called "Exploring the Nec
PC-8201a." It is out of print, but sometimes Club 100 or others
have copies. This was nice because it summarized the NEC manual
and was small enough to slip inside the case. It included port
pinouts, amoung other things.


Q. Are there any magazines currently covering the 82 and 83?

A. No. However the following magazines did cover the machine in
the past. Back issues may be available through libraries, etc.

- PICO - Wayne Green Publications - Included programs, technical
articles on most portable machines. Many articles on the NEC
machines.

- Portable 100 - (IDG?) - Originally for the Tandy machine, it
later covered the other Kyocera machines. Many articles applied
to all or were partially applicable to all.

- Terry Kepner's Portable News - (Portable Computing
International Corporation) - This tabloid size newsletter
started up in January of 1993. It took over the archives and
mailing list of Portable 100. It advertised back issues of
Portable 100 as available. I do not know if they are still
publishing. My attempts at telephone contact met with no answer.
Last contact address was:

Portable Computing International Corporation
145 Grove Street Extension
P.O. Box 428
Peterborough, NH 03458-0428
Phone: (603) 924-9455
FAX: (603) 924-9441


Q. Is anyone still selling stuff for these machines?

A. Yes, believe it or not.
Memory is still available from:

Purple Computing
2048 Southside Road
Murphy, OR 97533
(800) 732-5012
8k RAM chips, Memory cartridges up to 128k
(Confirmed 9/94)

Other miscellaneous stuff can be found from time to time from
the following vendors:

1031 S.E. Mill St., Suite # B
Portland, OR 97214
(503) 236-2949
Buys and sells Tandy and NEC equipment, buys 83s, sometimes has
stuff for 82 and 83.
(Confirmed 9/94)

Daniel Cohen
The Daily Planet BBS
Box 237
Plymouth, NH 03264
Phone: (800) 338-1839 (Sales - Voice mail)
BBS: (808) 572-4856 or 7 (8N1 300/1200/2400/9600)
E-mail: sysop@tdp.org
E-mail: 1:345/111 (Fidonet)
Mr. Cohen has been supporting these machines for years and has many
special products not available elsewhere. He has a FAX on demand service.
He provides full support so his prices are reasonable but do not
expect garage sale prices. People who have dealt with him
report they are very pleased.
(Confirmed 10/94)


Q. How do I keep my text file from running over the perforations
when I print using the LIST on the menu of my 82?

A. You need a print formatter, the LIST option from the main
screen was designed to list programs. A simple print formatting
program came on a cassette with the machine. If you have the
cassette you can try it.

There are several excellent formatting programs in the archive
on GEnie and Compuserve.

Here is a simple formatter. It is printed in a special format
to make it easy to understand how to modify it. Type it in like
any other BASIC program though. For example line 21 should be
typed as 21FILES:PRINT

Topic: NEC PRINT UTILITY


Q. My 82 or 83 used to remember files when I turned it off. Now
it doesn't. What can I do?

A. Your 82 and 83 have a small wafer Nickel-Cadmium battery in
them. It is recharged by the AC adapter or the penlight
batteries when the machine is not in use. They were designed
with about a five year life before they wouldn't charge anymore.
Yours just died.

You can try a couple of things.

1. You can keep it plugged in or AA batteries in it when not
plugged in. A set of AA batteries will keep the memory for about
a year if you don't run the machine itself off them. If you do,
plug it in when changing batteries.

OR

2. Open up the bottom of the case and take out the little
Ni-Cad. Some versions had a single wafer, others two wafers
together with heat shrink around them. Go to you favorite
electronics parts catalog or service man and see if you can find
a match.

OR

3. Take out the old one. Install a small battery holder (the old
cell was soldered in) and replace with any Ni-Cad that will fit
and is the right voltage and a similar amperage. There's really
quite a bit of room in the case where the battery goes.


Q. How can I run my 82 or 83 for six weeks in the desert without
all those AA batteries?

A. Because any 6 volt DC circuit can run the thing if it has the
right plug, just make a battery pack with 4 D cells in it. Take
along a set of AAs as a backup. You could also try something
fancy with solar cells to recharge batteries, etc., but the size
of 4 D cells is more practical. For emergencies, take along a
couple of wires with alligator clips and run it off the 6 volt
battery in your camp lantern.


Q. Where can I get a spreadsheet, scheduler, project manager,
etc.?

A. Try GEnie's Tandy Roundtable or CompuServe's Model 100 area.
There were quite a few of these things there last time I looked.
The listings are quite long to type in but the text files can
be converted using the instructions in the NEC manual.

You can also try The Daily Planet BBS (see above) with your 82 or 83.
Since this is a long distance call borrow the fastest modem you can.
Progams cannot be downloaded with the 82 or 83 unless you have first
downloaded the programs XMODEM.PCH and XMODEM.DO from The Daily Planet.
These two files are in a special text format. Any file ending in .ZIP
must be downloaded to a PC and unZIPped first. The only one on TDP at the
moment that qualifies is the one on using the Tandy Portable Disk Drive
with the NEC machines.

If you can't find what you want, E-Mail me at the above address and if I
have what you want I'll send it back to you.
