Back in 1990, when i was 13, my father gave me an Atari 800 xl. This is a (very) Basic program I made using the highest graphical capacity of 300x190 px.
In a tv, the output seems to have pixels in white, red and blue, but the graphics is actually made in just one color.

In over 2 hours, I only caught one Geminid on the 10th December 2017 despite having a very wide field of view.
The image shows Gemini to the far left, the Pleiades at the bottom right, the California Nebula middle right and Auriga in the centre.
Camera: Canon 300D modded
Lens: 22mm f/4
ISO: 800
Exposure: 28 x 5mins
Taken from Cumbria (UK)
Kicking off this campaign with a relatively straightforward 8-bit make-over. Love how the negative space arrow between the E and x translates into pixels.
M42_43 test shot with Narrowband filters using the new QHY163M camera. Taken 04/01/2017 from Cumbria in England.
This was my first test image with the camera and I've only just managed to get it processed. The calibration frames are not perfectly matched to the image due to the later changes introduced to get driver stability (resulting in a mismatch of image size). This won't be an issue in future images, but I hadn't set up a calibration library when I took these light frames unfortunately.
Scope: Takahashi E130
Focal Length: 430mm f/3.3
Camera: QHY163 mono
Baader filters:
H-Alpha: 30 x 30s and 30 x 5s
O-iii: 30 x 5s
Sii: 30 x 5s
Gain 12 Offset 60
The image is an HDR composite using the shorter 5s subs with the longer 30s subs in H-Alpha.
Great detail for such a short timeframe and only 30 subs per frame.
AMD produced what is probably the first floating point "coprocessor" for microprocessors, the AMD 9511 "arithmetic circuit" (1979), which performed 32 bit (23 + 7 bit floating point) RPN-style operations (4 element stack) under CPU control.
________________________________________________________________
AM9511 APU (arithmetic processing unit) performs floating point calculations that would be too time-consuming or cumbersome if done on Z80 microprocessor.
In addition to the four basic operations, the 9511 can implement transcendental functions (sin, log, etc.), and it can also perform conversion from floating point to fixed point and vice versa. It can also perform operations in 16 or 32 bit fixed point two's complement integer representation.
The fastest instruction is 16 bit fixed point addition which takes 4 microsec, the slowest instruction is arc-tangent which takes almost 2 milisec; 32 bit floating point addition takes 14-87 microsec.
The 9511 is an autonomous processor: it acts like a peripheral and it in not tied to any particular microcrocessor. AM9511 is configured as a pair of I/O ports with the capability of causing the Z80 to pause for completion of the processor's operation if it has not been completed by the time the Z80 code requires the results.
The 9511 is a stack orientaded processor. Operands are first pushed onto the internal stack, and then a comand is issued to the processor to perform an operation on the stack. Results are removed from the stack.
All transfers, including operands, results, status and command information, take place over an 8-bit bidirectional data bus. The internal data paths and the internal ALU are 16 bits wide, even though some operations are on 32 bits operands (this fact indicates that extending the 9511 to handle double precision format could have been implemented internally quite easily). The transcendental functions are evaluated using Chebyshev Polynomials which provide an even distribution of errors within the selected data representation.
The 9511 was in 1980's an high cost device: the APU was far more complex than the CPU and the volume of sales was not so high. As a result this was reflected in the price: in 1983 the Am9511@2Mhz cost £90 (considering inflation it would cost £240 now in 2009), the 3Mhz £123.75, the 4Mhz £146.25 ..
Some of the random 8-bit NES junk i've picked up here. The ? block is a portable speaker that also plays a Mario sound effect when you hit a button on top. The three diorama figures play short sound clips from the games pictured when you push the buttons on their bases.
This was the first computer I ever used. If I recall, my Dad bought it in 1982 or 1983 -- which made me 5 or 6 years old at the time. It wasn't long after that I was learning BASIC. The last time this beast was powered on, everything was working except the space-bar. I also have a newer (cost-reduced) sibling to the 800 known as the 130XE. I'm happy to report that the 130XE is sitting next to me, functional, and sees some occasional use.
Strobist Info - PM7500EDF bounced off white foam board to the right and left of the 800. Looks like the small fill on the PM7500 was also on.
Six of eight.
I might not do any tomorrow, my allergies are starting. :(
