History

2021-10-03: I re-created this page on my self-hosted web server.

2020-10-28: bb - multicomp 6809 - VGA - tested with both minimal and full (release_extram) image; both work, and both allow testing full ram 10 passes = ok. Connected up a usb serial dongle to FTDI port 1, used screen /dev/ttyUSB1 115200 - no output. Must verify port and pin connections.

2020-10-28: bb - multicomp - VGA - tested with 2 new AS6C4008-55PCN chips; the machine boots straight into ROM, and I can boot into any of the OS'es on the (CP/M) sdcard: Dos+, CP/M-2.2, CP/M-3, MP/M-2, BASIC, ZSDOS and ZPM3 (Volume 1-7) the remaining volumes can be mounted on drive B: or C:, they are (per system18.txt):

let me test a few.

2020-10-28: package with 4 x AS6C4008-55PCN from RS Online arrived today.

2020-10-26: ordered 4 x AS6C4008-55PCN chips, from RS Online this time. Cost: NOK 173.48 plus shipping NOK 110.- a total of NOK 283.48. More likely they will work.

2020-10-26: multicomp - tried with a AS6C1008-55PCN chip (128 K) in the socket furthest away from the VGA connector - it didn't work. Probably needs changes to the RTL. This should help: Multicomp playground nice!

2020-10-26: multicomp - checked power to the two AS6C4008 memory chips - power is good. Switched the two chips, didn't help, I still get errors on (Camelforth) memory test. Replaced the chips with the two other AS6C4008-55PCN, same problem - memory errors. Not surprised, they're from the same order.

2020-10-25: c1 - ada2p4 - downloaded the multicomp09_iram.zip file (and the multicomp09_nov2016.zip file) and tweaked the minimal 6809 machine until it compiled. Camelforth came up, and I could test the VGA (no colors?) and the external memory per this page. Unfortunately, the memory test

HEX
1000 1FFF PASS

fails with lots of "Error@address".

1000 1010 PASS

also reports only errors. Either my RAM chips are bad (possible) or the pin assignments are incorrect (must check). A while later - pin assignments appears to match.

2020-10-25: microSD card module pinout - (component side up, sdcard towards you, pins away from you) left to right: gnd, miso, clk, mosi, cs, 3V3.

2020-10-23: eb - sdb6 - Multicomp - tested Microcomputer_VGA, Microcomputer_TTY on this machine, same result as on bb machine.

2020-10-23: bb - sdb5 - Multicomp - compiled Microcomputer_VGA project and used jtag to program the fpga,

I get a blinking cursor on the VGA monitor, then nothing happens. Connected a PS/2 keyboard, the num lock led turns on and off when I press the num lock button, that is all.

2020-10-23: bb - sdb5 - Multicomp - write a cp/m and more image to a microSD card: this image

2020-10-23: soldered pins for 5V onto the Multicomp extension board. Figured out that the EP2C5 board has center positive on the barrel power connector, and where positive is on P8 (hint: it is not the square pin) and soldered a power connector lead onto the board. power-on test - connected the two boards together, connected the power lead to the Multicomp extension board, and powered on. Turns out the the LEDs on the Multicomp extension board (D1, D2, D3) matches the LEDs on the EP2C5 board (D2, D4, D5) so when the board is powered the default bitstream makes them blink. Good.

2020-10-22: Multicomp extension board - soldered on most of the components, added two RAM chips to the sockets. Figured out the pinouts for

SD Socket - gnd on the left when you read "SDSocket" the right way

ftdi232 - when you can read "FTDI232" the right way, from left to right: gnd, cts, (VCC - not connected), txd, rxd, rts

2020-10-21: Multicomp extension board - started assembling the board

2020-10-13: eBay - the package with the 4 x AS6C4008-55PCN chips arrived.

2020-09-25: eBay - I ordered 4 x 1pcs AS6C4008-55PCN AS6C4008 55PCN Integrated Circuit DIP from a seller on eBay - adeleparts2010 ( 86731 ) - for USD 24.72 + USD 4.- shipping, USD 7.18 VAT, a total of USD 35.90.

2019-09-17: according to blwiki, the pin assignments are

fpga connected
pin  to
  3  D2 LED
  7  D4 LED
  9  D5 LED
144  KEY pushbutton. Push to ground, no external pullup. Set internal pullup on FPGA configuration if used.
 17  50 MHz clock input
 73  10uF capacitor to ground. 10K resistor to Vcc, for power up reset if needed?
 26  VCC 1.2V. Only needed for EPC28. The "zero ohm" resistor could be removed and the pin used as normal.
 27  gnd. Only needed for EPC28. The "zero ohm" resistor could be removed and the pin used as normal.
 80  gnd. Only needed for EPC28. The "zero ohm" resistor could be removed and the pin used as normal.
 81  gnd. Only needed for EPC28. The "zero ohm" resistor could be removed and the pin used as normal.

nice to have an example

2019-09-16: ebay - I got 1 x CycloneII EP2C5T144 FPGA Development Board + ALTERA USB Blaster JTAG programmer in my mailbox. Tested the board - detected ok with a DirtyJTAG cable and urjtag:
