||A real gem. This is
the first home computer I ever came in contact with. We used it
in school to program simple games and even built a memory
expansion unit to it. I was probably around 13-14 years old then.
||We had this computer
in my school and we used it to create programs for a MC6800
development system. It was based on the Zilog Z80 running at 3 MHz and had 16 KB RAM, expandable to 32 K, and 16 KB ROM containing a fast semi-compiling BASIC interpreter.
ABC 80 normally used a tape recorder for program and data storage, but could also be expanded to handle disk drives. Some sound effects could be produced by a Texas Instruments SN76477 sound chip which was connected to an 8-bit output
port.The monitor was a black and white TV set modified for the purpose.
I have two systems in good condition. I also have the expansion
box and dual floppy disk drive system.
||A nice little
computer with most of the things you needed on board. 32Kb of
RAM was not really enough especially since this memory had to
server as screen memory as well.
I was never a user of this computer but it is really neat with
its slender look. The keys are awfull though as they seem to get
stuck when you don't hit them straight down.
||A great computer
with a somwhat strange Basic interpreter. It was very fast for
its time and had a built in assembler for even higher speeds.
Needed a tape recorder to store programs. This is the first
computer I ever bought my self. It was purchased on the fall of
1980. I still have the receipt for it.
||Now this one is not
my original machine. I got this from the UK of ebay. The casing
and keys are in mint condition and it really looks brand new. I
remember my old 800 was very yellowed by the sun, but this one
looks new. Later I have also purchased a brand new 810 diskdrive
for it. Just recently I also received another 810 and a 850
serial interface. These were in terrible condition. Dirty and
almost dark brown in color. But they will suffice as spares.
||One of my collegues
at work found out that I collected old computers and dropped
this one of at my desk. It's a non working unit but I do believe
that it's aunty Sally that has caved in. Will replace it when I
get the inclination.
||I have 2 of them. I got
them for 0.99 GBP + another 15 GBP in shipping. I just could
not let that deal go to waist. They are in bad physical condition but
both of them work. One has a broken
space key but I will get to fixing that soon. This one is
currently hooked up to my logic analyzer for analysis of the
ANTIC and GTIA waverforms for my FPGA implementation.
||Same as 65XE, sold
only in Eastern Europe.
The case is really yellow though and it looks like crap.
||Got it from Ebay, No
signs of yellowing and works OK.
||Replaced the 800XE
unit I used as a development unit with this one. It will receive
an internal myIDE interface attached to a Compact Flash Card. I
also have a Freeze card connected to it.
||This is my 1200XL
unit. It is in great condition with almost no yellowing and the
keys show very little usage. It is actually one of my favourites
because of it's look.
||This one is just to
cool. A collegue of mine dug this one out from his girlfriends
stuff and handed it over. It works flawlessly and is in
mint condition. I actually still use it sometimes during
meetings. A great eye catcher...
||This is the most
recent addition to the growing collection. This one will
actually be actively used. I have installed a CT63 board and
512MByte of RAM + a 80GB harddisk in the original case.
(I sold this one
to focus my collection on 8-bit computers)
||Here's a nice little
computer. This unit is completely unmodified but looks really
old and yellow. I received a 16KByte expansion unit with it as
well as a cassete player and a few games.
||Boxed brand new
unit, which has never been used. The box shows a little wear but
otherwise everything looks brand new.
||Got this from eBay
on a rather good deal. It was on elderly lady selling it after
her husband passed away. She stated that it was broken in the ad
but I bid anyway. When I got it i saw that it was in very good
condition and after exchanging the power supply to a modern
switched supply it started up right away.
||On of the local
churches was selling of stuff from their inventory to get money
for some charity purpose, can't remember what it was now. I got
my unit for a few 100 SEK, it looks like crap though but with a
little TLC I think it will look as new again. It works and I
have installed a FLASH card in it to hold all my software. Quite
||I have worked a bit
on my Apple III with great results. As it turns out it is
painted with a very resiliant paint and after washing it
thoroghly it actually looks very good.
First starting tests have
failed so it needs to hardware analysis before I proceed any
further. It will also be converted to a 240V maching with a new
switched power supply.
||Found this one on a
local flee market. It was quite an amusing story. I noticed the
Mac directly when we got to the market and asked the guy how
much he wanted for it. 20 kr he said (aprox 2 EUR) but there are
a lot of things missing like the keyboard and stuff. OK I did
not want that so I left. But when we passed the table the next
time there was another guy there and for some reason I asked
him, and low and behold he just took out a box from under the
table with keyboards, disks, mouses and a lot of accesories. So
I bid 20 kr again and got it. Best part, it works perfectly. It
is in excellent condition and is a real work of art.
||Just got this from
the lady that does the books for my company. Her soon has just
left home and she was about to throw on the dump !!!!! It was a
complete package with computer, 3 Wico sticks, monitor and about
a zillion of diskettes. Anyway, the computer starts and the
harddisk has checked out OK
||Now here's what a
computer should look like. Sturdy wooden sides and 1.5 mm thick
steel plates makes up the chassis. It's a tank. My computer does
not work at the moment, but I have acquired an analysis board
and will make an attempt on getting it up and running. The
wooden sides were damaged when shipping the unit due to really
poor packing and I have had to have them remade by a skilled
carpenter. The multiplication button is missing from my unit so
if anyone has one to spare please get in touch.
||These are my joy and
pride computers. I have two of them. The first one I got is not
the original computer made by MITS. Instead I purchased a new
kit from Grant Stockly who makes them. Check out www.altairkit.com.
The second one is an original
unit which donated to me by mr. Jon Anderfeldt.

|Here's another gem
from a Swedish manufacturer of early computers. The Jet80 is a
terminal based CP/M computer powered by a 6MHz Z80 and with
advanced networking capabilities. I bought this unit a few years
ago brand new, but never tested and of course it does not work
properly. I have debuged the unit and cam to the conclusion that
the DRAM isn't working properly. But someday i will fix this.
