Developer plays TV series on PC from 80s




A developer has gotten together to play the intro of science-fiction series Doctor Who on a PC from 1983. From diskette can see the video on the TRS80 Model 4P, a computer with a 4MHz processor and 64Kb RAM.

The developer uploaded the video on YouTube a few days ago, but gave only Wednesday explaining how he got it done. The video plays on 118×48 pixels at 25fps. The TRS80 has two 5.25 “floppy drives, every 32 milliseconds which can read a byte. Of these, the program 13,5ms used to read out the data, while the remaining 18,5ms be used to decode the data, and the screen to build up, writes Extreme Tech.

To play the video of thirty seconds, the developer must, who made himself known only by his nickname gp2k00 use, four floppies. The floppy disks each have 180kb of data; Every seven seconds a floppy must be changed. The developer does not say a whole movie to want to look this way, despite being so is possible.

The PRS-T80 Model 4p runs on a Zilog Z80A processor with a clock speed of 4MHz. The computer has a memory the size of 64KB. The computer was on sale from 1983 US retail RadioShack.
