Subject: CP/M Z80 home brew computer circuit board
Hi,
If anyone would like to make their own low cost home brew Z80 CP/M
computer please contact me by email.
I have manufactured PCBs available for sale for $20 each plus shipping.
Preprogrammed EPROMs are also available for sale.
The hardware and software are documented including schematics, source
code, binary images, PCB layout, parts list, etc.
Details of the single board computer are available at:

Thanks!

Hi All,
Just in case anyone is still interested in building their own Z80 CP/M home
brew SBC here is your opportunity. I have sold most of the PCBs in the
first batch. As of this morning, I have less than 25% of remaining stock.
I recommend that if you are going to order one of these PCBs then you should
do it soon. I do not know if or when there will be another batch. If there
is, it takes three weeks from my order to delivery and delivery to you is on
top of that.
Most likely, the demand for home brew / classic computer PCBs is fairly
limited to a small group of enthusiasts. Ordering more PCBs at a practical
unit cost is a delicate issue since I would like to get them out for people
but also want to limit my personal expenses on this to a reasonable level.
I do not expect to fully break even on the project but at least not lose my
shirt on it either.
Probably it means the next batch will involve a waiting list until there are
enough people signed up to make the order practical. If anyone has better
suggestions on how to do an amateur electronics project or a better idea, I
am open to *constructive* input. I do appreciate your helpful comments.
Please do not reply with "I don't like your project because..." Those
comments aren't very helpful and IMO generally just contribute to the noise
on CCTALK.
Thank you in advance and have a nice day!
Andrew Lynch
