Happy or US Doubler?

US Doubler's merit is you can build one yourself from about $4 of parts from eBay... if all you need is Double Density and Ultraspeed support. Happy & Speedy add track buffering, copy protection copying etc.

 

Speaking of which, you should also consider Speedy nowadays (ie tf_hh's mini-speedy) instead of Happy now that it has a NTSC compatible ROM.

is that speedy or super speedy?

Speedy was first.. The Super Speedy was made for ABBUC to duplicate disks fast, as it could buffer an entire DD disk in it's own RAM. Can read or write an entire disk in like 15 seconds. Only like 7 were ever made. More people can experience it today with Mega-speedy, which can emulate both.

 

Mini-speedy is a mini replica version of the original speedy (by tf_hh). Functionaly identical to the original speedy, except maybe the buzzer on the original. New firmware 1.7 is now compatible with NTSC machines so north american users can experience for the first time as of around 2016 I think.

MEGA - Speedy, it's everything! W00t!

that's kind of where I was hoping it would lead/end but...

 

1. Mega SPeedy

2. Happy 1050

3. U.S. Doubler

 

as add-ons for 1050

 

1. Ram Charger

2. SRam

 

as add-on to the iNDUS

 

what's your list for 810?

Problem with the Mega Speedy is it's not available from anymore unless you can convince a kind soul to give up an extra from the original production run..

 

Mini speedy, happy 1050, USDoubler, bitwriter, all have replica versions currently available...

For price comparison:

 

mini-speedy is 20 EURO (about $22 USD) + shipping

details here: http://atariage.com/forums/topic/277204-some-new-not-really-hardware-made-by-tfhh/

 

Happy 1050 from AtariMax is $40 USD + free shipping

 

So about $8.00 total difference and 7 to 10 days longer to get it?

Yeah.. and of course the shipping price gets lower per unit if you order more than one. :)

 

Mini-Speedy has other neat tricks beyond what the Happy does, like always read and write-back caching of the boot sectors, DOS 2 directory/VTOC sectors, and DOS 2.5 ED extra VTOC/directory sectors, reducing extra back-and-forth of the head when copying lots of small files..

So It seems that the consensus is so far :

 

1. Mega Speedy (which can't currently be had)

2. Mini Speedy

3. Happy

4. US Doubler

 

I'll be honest and admit that I do have a Doubler from Atarimax. It's a very installation, which I also like. Are the Speedy installations

as easy as the Doubler?

You can buy supposedly 'authentic' US Doubler from B&C or BEST, although I was disappointed to receive an EPROM from B&C earlier this year...

 

Haven't mentioned Turbo 1050 yet in the thread, but that is another interesting beast, of which replica's are available from TF_HH... Adds Double-Density and faster than ultraspeed with no additional RAM - only a comparatively large 32KB ROM.

 

Summary of install methods for each:

  • Any variant of Happy 1050, authentic or replica, and Mini-Speedy use the same install method: Remove U10 (ROM), Remove U9 (6507 CPU), plug happy board into U9.
  • US Doubler: Remove U10 (ROM), Insert USDoubler ROM into U10, may have to move jumpers to JP2 and JP4 (for EPROM configuration), remove U8 (6810 RAM), Install ICD black epoxy module into U8, or homebrew dual-stacked 6810.
  • Turbo 1050 - Remove U10 (ROM), and insert Turbo 1050 board into U10. There's a jumper on the PCB to configure the board for either ROM jumper config.

Mini Speedy looks more useful than Turbo 1950 as the latter requires special formatting for high speed as it does not have a track buffer. It‘s obviously a clever piece of kit but with today‘s RAM prices it‘s former price advantage is mooted.

 

MegaSpeedy requires an external mod for the control panel (so don‘t feel too bad about it being not available). I have one each but only use SIO2SD currently, so no practical use experience here.

As long as the RAM module is epoxy encased with the ICD logo I would consider it original, since the US Doubler has both ROM and EPROM versions.

For upgrades that can actually be purchased, the only other upgrade is the BitWriter 1050 Replica from tfhh, so the choices are:

 

- US Doubler

- Happy 1050

- Turbo 1050

- Mini Speedy

- BitWriter 1050 Replica

 

I have no idea what else can be made using info available on the net.

 

The flip side of how long shipping takes is how long it will sit on the shelf before you have time to install it.
