(under construction)

This is my original Acorn BBC Model B (issue 7), purchased in 1982 at Vogelzang electronics in Heerlen.

Over time, I installed:

  • The Intel 8721 floppy disc controller chip plus assorted ICs
  • A Sideways ROM extension board
  • The Acorn Speech Synthesizer Upgrade featuring Kenneth Kendall (the BBC news reader). This was based on a TMS5220 phoneme generator plus a TMS6100 “Phrase ROM” (PHROM) chip.

I built my own Light Pen (connected to the 6845 CRTC). Unfortunately, these light pens only work with old CRT TVs or monitors, not with modern LCD screens.
