re: "TWGS not friendly with Appletalk???"

[harold.h@genie.com]

FWIW,
 
For the last two months I have been running a 14Mhz TWGS in a "Turbo-28"
(prototype ROM_03 IIgs (with production roms installed)) on an AppleTalk
network, with =ZERO= problems (not one single crash / lockup that I have
been able to attribute to the hardware (many I could attribute to bugs
in code while developing ;))
 
My 65C816 is a 14Mhz rated part, not a -E (eng sample) etc.
The cache in use is ISSI IS61C256AH-15N (15ns) installed on a modified
original (8k) cache daughterboard (no series resistors in the adr lines)
with a v1.8 TWGS rom installed.
 
The GALs on this TWGS are as follows:
AE #         Lattice #      Lot #
===================================
TWGS1A-I     16V8A 15LP     891532
TWGS2A-I     16V8A 15LP     891532
TWGS3B-I     20V8  25LP     891514
TWGS4A-I     20V8  25LP     891112
TWGS5A-I     20V8  25LP     891811
TWGS6A-I     16V8  25LP     892520
TWGS7A-I     16V8  25LP     892407
TWGS8A-I     16V8A 15LP     891535

I have modified two other TWGS's in like manner, all three have proven
themselves reliable to me.
 
Memory - CVTech Rev-A 4Mb board w/3Mb installed, Apple 1Mb in back pocket
SCSI - Rev-C RamFast w/3.01e roms, loaded SCI chain
Case - Full sized tower w/300w supply.
