Other Homebrew 6502 Computers:
- André Fachat's
site - Designs for several more advanced 6502-based computers including the
Gecko and CS/A65. Also an operating system for these machines (and possibly
other 6502 designs) called OS/A65.
DIY6502 by Douglas Beattie - A design for a single-board 6502 computer with
similar specs to my own, with schematic and wire-wrap layout. You can also got
a 6502 cross-assembler for the PC at this site.
- Harry The Bastard's site -
Harry has made a 6502 machine to provide security for his van.
- Phil Pemberton's site - Phil
is another 6502 fan, and is planning on building a 6502 machine soon.
Electronic Component Suppliers:
- Farnell - Massive range of components,
free catalogue on request, good on-line ordering, and free delivery (min. order
- Maplin - Good range, online ordering,
and shops throughout the UK. The catalogue isn't free though.
- RS - Another big UK-based electronics supplier
with on-line ordering.
- Greenweld - Stock a fairly limited
range of standard components (but can be cheaper than Maplin). The main
attraction is the surplus items they sell - all sorts of exciting electronic
bits at ridiculous prices, e.g. I bought a 60W switch-mode power supply for £3!
Unfortuntely these items aren't listed on their site, so you'll have to ask to
be put on their mailing list.
- Bull Electrical - Like
Greenweld they have a modest range of standard components but lots of
weird/cool/cheap surplus items (they are famous for recently stocking lasers
from Chieftain tanks!). Their website is good, with online ordering, and they
also have an auction site.
- Dallas Semiconductor - Produce reset
devices (I use the DS1813) and real-time clocks.
- Rockwell - Make the 6502, 6522
& 6551, but don't admit this on their web site. They'd rather tell you about
their modem chipsets.
- ST Microelectronics - The new name for
SGS-Thomson. They make the M28C64C EEPROM which I have been using.
