Compact Flash Module adds storage option for the RC2014 homebrew Z80 computer

This listing is for v1.3 of the RC2014 Compact Flash Module. For the differences between V1.3 and V2.1 see the RC2014 Compact Flash Module v2.x page What is RC2014? RC2014 is a simple 8 bit Z80 base…

What is RC2014?

RC2014 is a simple 8 bit Z80 based modular computer. It is inspired by the home built computers of the late 70s and computer revolution of the early 80s. It is not a clone of anything specific, but there are suggestions of the ZX81, UK101, S100, Superboard II and Apple I in here. It nominally has 8K ROM, 32K RAM, runs at 7.3728MHz and communicates over serial at 115,200 baud.

As a bare minimum, you will need a CPU, ROM, RAM, Clock and Input/Output module. The RC2014 is designed in such a way that you can build your own modules to expand it. As such, if you have access to similar components, or have specific needs, you might not need all the items I have on offer.

What is this module

This module adds solid state disc storage to the RC2014. Primarily it is intended to be used for running CP/M when used alongside the 64k RAM Module and the Pageable ROM Module. It is not accessible directly from BASIC as supplied with the regular RC2014.

The CP/M distribution, as modified by Grant Searle will support 64MB or 128MB compact flash cards. Larger sizes can be used, however a maximum of 128MB will be available. A 128MB card is split in to 15 x 8MB drives and 1 x 2MB drive, available as Drive A: to Drive P: and a 64MB card is split in to 7 x 8MB drives and 1 x 5MB available as Drive A: to Drive H:

In order run CP/M you need the following set up as a minimum; 7.3728Mhz Clock Module, Serial I/O Module, Z80 CPU Module, Pageable ROM Module, 64K RAM Module, Backplane (Either Backplane 8 with additional connection between ROM and RAM, or Backplane Pro) and CP/M Console on ROM

Please be aware that the pitch of the pins on the Compact Flash socket is very fine, at 0.635mm (0.025 inch), which is a quarter of the pitch of the other components on the RC2014. With patience, a good eye and a steady hand it can be hand soldered on without too much trouble. If you prefer to use solder paste with either a reflow station or "toaster" oven, I now offer a laser cut stencil to allow the perfect amount of paste to be spread on the board.

For those not brave enough to try, however, I will also be offering the PCB with this connector already attached and tested. Note that this might add a few days to the shipping time.

What do I get?

Standard kit Includes the PCB, headers, socket, chip, resistors etc and the compact flash connector
Standard kit + Stencil As above but includes stencil
Part built kit As standard kit, but the compact flash connector is supplied fitted to the PCB
PCB Only Only the bare board
Compact Flash 128MB or 64MB Compact Flash, pre formatted with CP/M installed and essential utilities already installed on Drive C:. You need to select which serial module you are using, either the standard 68B50 as supplied in the Full Monty kit, or SIO/2 Dual Serial
CP/M Console ROM 27C512 64K with CP/M Console loaded at 0x8000 and 32k MS BASIC at 0x0000 . To be used with Pageable ROM Module

Products are normally shipped next working day, however during busy periods this may extend slightly.

Tracked or Tracked & Signed options are available to most locations. This may not get your kit to you any quicker, but it adds peace of mind that you know where it has got to.

good device

Works nicely with SC203 kit. Needs to be in close proximity to CPU card due to the reality of the technology. thanks!

Aleksandr Vladimirovich | Sept. 15, 2021

Nice kit.

Great kit! Packaged great. Сomprehensive documentation. Easy to assemble. The seller is a reliable person.

Easy to Build and an Excellent Mass Storage Unit

Ordered with the CF socket pre-installed, this unit was assembled in quick order. Performance on the SC126 Z180 computer is superb. The board itself has one less row of contacts than the expansion bus so be careful to "index" it in place with the [Pin1] marker.

Dean | April 11, 2021

Was up and running with the CF module in no time at all.

A very easy to build kit - I got the version with the CF slot holder already solder - so it did not take too long to complete the kit and boot up from it.

The RomWBW drivers worked perfectly.

Programming the CF directly is not that hard either - if you are really feeling adventurous

Dean.

PS: Shipping to Australia was very quick -- this was a very pleasant surprise.

Angus | Feb. 10, 2021

My CF adaptor card kit has arrived.

Shipped on 18/Jan/2021 and I have it on 11/Feb/2021. 24 days in the midst of your pandemic is not to bad I think. Australia Post opened it but they haven't lost any parts such as what happened on a previous order.
I chose the partially assembled kit. I watch Julian Ilett on You Tube handle surface mount components and other miniature components but these days, not for me thanks. I can barely read the chip labels.
Anyway my SC126 will soon have some more mass storage. I took the option of a SD card interface which works fine but as I also have a Linc80, I have a handful of SD cards to play with.

John | Jan. 5, 2021

Went together smoothly, working great!

The card went together with no problems, the documentation was great. The CF card sure made a difference in the system speed and ease of use.

Thanks again.

Jeffrey | Dec. 18, 2020

With this version the CF module is NOT soldered!

This is the second CF Module I purchased. The CF Module on the first was already soldered. This one is not. It is a surface mount item and far too close for my 70 year old hands and eyes. If you cannot solder a very close pitch, do not order this kit.

PS. I believe there is a drop down option on the purchase selection to order the soldered version at extra cost. I just saw that when I ordered another.

Storage for RC2014

Bought the kit without the CF socket pre-soldered. Definitely not one for inexperienced solderers. Needs a very fine soldering iron, a steady hand, solder paste and plenty of desoldering wick to clean up the inevitable solder bridges.

Worked well with CP/M and z-system.

Compact Flash Module for CP/M RC2014

A very good product.
Unfortunately, I don't have the tools to make the connection
of the CF carrier.
I get a stencil.
Good support.
thank you

Neat CF Module

This RC2014 card provides an addressable (the address is 'alterable') support raft for a Compact Flash card module, providing the RC2014 with some persistent storage. It's the easiest RC2014 module to build, imho.

To be honest, I found that the module gave better results when used with the RomWBW configuration rather than the default ROM that comes with the RC2014 Pro. At least in RomWBW, I could use the CF card to store one (or more) mbasic programs and those programs could use the CF card for data storage and retrieval - I couldn't get the default ROM's Basic (28K or 56K versions) to 'Save' or 'Load' - This could be just down to my overlooking something in the documentation, however!

The RC2014 definitely needs a means of providing persistent storage and, accepting slight reservations highlighted, above this module fits the bill.

Good Kit

This is a relatively simple but challenging kit. The big issue is, of course, the compact flash socket. The fine pitch of the connections makes soldering of individual pins impossible. Soldering it down and using copper solder wick braid to remove excess solder bridges worked well for me. I was shorted the 74HCT138 address decoder chip on 2 kits, but I had spares to fill in.

Tobias | Oct. 28, 2019

Recommended!

Shipping was fast, assembly was easy. I recommend to have some (good quality, with flux) solder wick for the CF card connector. M2 screws and nuts can be added to give it some additional support (not included in the kit).
Thanks!

Craig | Sept. 18, 2019

Loved the kit!

It went together quickly, without problem. had com running after about an hour. Thanks for creating a great set of kits.

Fantastic

This works great and is a must to use your RC2014 with cpm.

I can recommend this. Well done Spencer

To be used with cp/m

I like this module, it's surprisingly simple. The soldering is easy, too, except the surface mount part, the CF card holder itself. But with a good magnifying glass you can do it :-)
The quality is very good, the seller very patient and helpful!

Eric | June 14, 2017

Great

The quality is top.
Worked on first power-up (once you remember to hit reset ! )
Modularity is maximum.
I'll be using it for learning hardware development, drawing schematics, routing PCBs, and such.
