UltraWarp

UltraWarp v1.91G (ReActiveMicro distribution)

The UltraWarp is an accelerator board for the Apple II, II+, and IIe systems. It was conceived, created, and designed by Michael Mengel.

ReActiveMicro worked together with Michael to help bring the project to the Apple II Community, and was released for sale from the ReActiveMicro Store on June 13, 2017.

Project Status: Complete. In production. Actively sold by ReActiveMicro.

Support: Post on the Discussion page (link above) or email ReActiveMicro Support.

Sales: Visit the ReActiveMicro Store.

History

Michael Mengel stated "Originally I designed the card on an Apple II+ and BASIS 108 to accelerate my favorite programs CHESS and CHECKERS, inspired by an article in creative computing 1982 ("New Processors for The Apple")."

Michael has listed a few boards for sale on eBay, but never considered mass production.

On March 5th, 2017 Henry contacted Michael Mengel about helping bring his project to the Apple II Community. After some email exchanges and design reviews, a initial PCB order was placed by ReActiveMicro and soon after the boards were confirmed working and released for sale in the ReActiveMicro Store.

Versions

Michael produced a couple versions of the UltraWarp board. The last and most current version was v1.91G and usually has the speed of 13MHz. Some boards however have been over clocked as much as 18MHz.

ReActievMicro has produced several versions of the UltraWarp board. The last and most current version was v1.91G and usually has the speed of 13MHz.

In June of 2017 Henry made a relayout of the v1.91G version to move more parts to SMT which allows for a less costly assembly. This revised version was called UltraWarp v1.91RM, and 3 protos were ordered for verification of the new layout. This new design could also allow a kit version of the board to be produced and sold.

Controlling The Speed

There is NO need for RESET after the SLOW-POKE or FAST-POKE!

Like all accelerators for the Apple II, UltraWarp can also be controlled by softswitches.

Location Action Function

$C05D W Low speed (1 MHz) $C05C W High speed (set on power-up) $C05B W Disable

The following example in Applesoft Basic will slow the UW to the 1 MHz clock rate.

POKE 49245,0

Next example switches back to full speed.

POKE 49244,0 (without RESET)
