I have now completed layouts for a PCB for the MFM disk reader and emulator
that I mentioned back in February. I will add to my order boards for others
who are interested. I am not planning to kit or assemble. You will
have to do that yourself.
For information on the board see
http://www.pdp8online.com/mfm/
Email me if you have any comments or questions.
I did two different layouts, one all through hole and one with 3 surface
mount chips that has some minor advantages. See link above for discussion.
I plan to only order one version.
If you are interested in a PCB's email me djg@pdp8online.com with
1) How many you wish
2) If you prefer or are only interested in the through hole or surface mount
version.
Unless you state I don't need to I will email you back when I get ready
to order with the final price for confirmation that you still wish them.
I plan to collect money when I am ready to ship them.
The cost to make one is:
Beaglebone $55 (they increased the flash by 2G and the price by $10)
PCB $30 (depends significantly on quantity)
Parts $54. Can reduce by $24 if you don't need the holdup capacitors.
See the BOM for parts and prices. See description of board for what
the holdup capacitors do.
TBD Shipping
Unless only a few are desired I will likely buy a couple cheap PCB's without
the hard gold on the edge fingers to verify I haven't made a serious error.
This will delay final order. I tried to get my cat to peer review but it only
shredded the paper.
