TransWarp GS 32K Cache Upgrade
============================================ Apple IIGS Product Info Released February 1996 TransWarp GS 32K Cache Upgrade Available ============================================ This document may be distributed freely as long as it remains unchanged. (c) 1996 ///SHH Systeme, Joachim Lange. If you still have a TransWarp GS equipped with 8K cache, here is the chance to upgrade to 32K. We have done a re-make of the original 32K board and will offer these boards to the Apple II community. Boards are immediately available. Description: Re-designed version of the original TransWarp 32K cache piggyback board. Improvements in the new layout: careful and efficient VCC (+5V) and Ground routing, _double_ decoupling capacitors for each integrated circuit. Resistors and capacitors are SMT type components. Shape of board and positioning of the main components very similar to the original layout. Board has solder masks (solder resist) on both sides. High-quality industry standard. (A GIF picture of the bare board should be available at the same location from where you received this document.) Important note: Speed upgrades on the TransWarp GS can be done by enlarging the cache size and/or using a faster microprocessor and clock frequency. It is possible to speed-up the TransWarp card to higher clock frequencies, and our TWGS 32K cache board replacement also works fine with these speed upgrades. However, due to the limited speed capabilities of the TransWarp GS (design made in 1989), nobody can _guarantee_ that _your_ TransWarp GS will work at the non-standard speed (the clock frequency) you want to go. In other words: Some TransWarp cards work fine at higher clock frequencies, others don't, regardless of whether you have equipped the TWGS with a 32K cache upgrade from us or from any other source. We can offer you our TransWarp GS 32K cache boards in three different versions: "do-it-yourself", "dirty-work-done", and "almost plug-and-play". ================================================================== Option A: Bare boards ("do-it-yourself") ================================================================== --} Minimum order here is 6 (six) boards! {-- What you get: -------------- Two-layer piggyback boards for the TransWarp GS with solder resist, ready for soldering all components. A sheet of paper with short but reliable instructions how to assemble the board. NOTHING ELSE. Heavy soldering required! --> With this option: YOU ARE ON YOUR OWN. NO QUESTIONS PLEASE. NO SUPPORT. YOU ARE ON YOUR OWN. NO QUESTIONS PLEASE. NO SUPPORT. YOU ARE ON YOUR OWN. Additional parts required for full functionality: -------------------------------------------------- 3 (2-row x 10-pin) header connectors, gold plated preferred. 6 DIL-14 0.3 inch wide sockets (two for each 28-pin cache RAM) 1 DIL-28 super-flat 0.6 inch wide socket for the firmware EPROM (max. 0.1 inch total height from board surface!). 8 SMT (surface mount technology) decoupling capacitors 100nF. 3 SMT resistors 100 Ohm. 1 SMT resistor 10 KOhm. 3 cache RAMs 62256-xx or equivalent, xx for the speed desired (-35ns, -25ns or -15ns, any value between these will suffice, depending on the maximum clock frequency) 1 Firmware EPROM TransWarp GS (v1.7 or v1.8 required) Very good soldering skills and the ability to insert the firmware EPROM and the cache RAMs correctly! ================================================================== Option B: Populated boards, without semiconductors ("dirty-work-done") ================================================================== Since it is much cheaper to buy expensive semiconductors (such as cache RAMs) in your own country, you might prefer this version. What you get: -------------- A two-layer piggyback board for the TransWarp GS with solder resist. All non-semiconductor components (sockets, resistors, capacitors, header connectors) mounted and ready for use. A sheet of paper with short instructions how to add the components not included with the board. All board functions verified. No soldering required. Additional parts required for full functionality: -------------------------------------------------- 3 cache RAMs 62256-xx or equivalent (0.3 inch wide), xx for the speed desired (-35ns, -25ns or -15ns, any value between these will suffice, depending on the maximum clock frequency) 1 Firmware EPROM TransWarp GS (v1.7 or v1.8 required) Enough skills to insert the cache RAMs and the firmware EPROM into their sockets correctly! ================================================================== Option C: Fully populated boards, without Firmware EPROM ("almost plug-and-play") ================================================================== What you get: -------------- A two-layer piggyback board for the TransWarp GS with solder resist. All components but the firmware EPROM soldered and ready for use. The board includes all sockets and three 32K cache RAMs 62256-15 or equivalent (fast enough for processor clock values of 14 MHz and more). A sheet of paper with short instructions how to add the components not included with the board. All board functions verified. What you need for full functionality: -------------------------------------- 1 Firmware EPROM TransWarp GS (v1.7 or v1.8 required) Enough skills to insert the firmware EPROM correctly! Another important note ======================= The TransWarp GS firmware version 1.5 that came with the TransWarp 8K version does not work with 32K cache boards. You absolutely need v1.7 or v1.8 for 32K cache operation. Since the firmware is copyrighted material, we cannot supply copies of the firmware. The cache RAMs required for the 32K cache have many different denotations. It's almost impossible to list all kinds that are available and suitable. If you want to order cache RAMs from elsewhere, just be sure to order three 32K * _8bit_ wide static C-MOS RAMs in 0.3 inch wide DIL (dual-in-line) package. Support for all products from ///SHH Systeme ============================================= Only the B: ("dirty-work-done") and C: ("almost plug-and-play") options are supported. As usual, you have the following sources for support (most preferred comes first): --> GEnie: Go to the A2 area (m645) Go to the Bulletin Board, SET category 46, read or write topic 14. --> E-mail: Write to: Internet e-mail: JLANGE@TASHA.MUC.DE CompuServe e-mail: 73370,3106 --> CompuServe: Place your questions/comments in the message area of the Apple II Users forum. We are checking messages about every week. ===================================================================== TransWarp 32K Cache Board Ordering Information: Terms And Pricing ===================================================================== As described before, three versions are available.
