Titan Accelerator for the II Plus

[Stephen Shaw <xstephenx@apple2.org.za>]

When Titan made the Accelerator II for the II Plus they were very nasty and
sanded the identity numbers from the tops of the chips and replaced them with
their own in house numbers. I dug my Apple II range Fairy IC test card out and
here are some of the disguised numbers.

Titan number		Identified as:
40000/40023		74LS02/28/128
40001/40008		74LS393
40002			74LS86/136
40006/10/20/26		Not known at present.
40007			74LS175
40008			See 40001
40009			74LS08
40010			See 40006
40011/12/14/15		74LS158
40016/40027		74LS00/24/37/132
40017			74LS259
40018/40019		74LS367
40024			74LS161
40025			74LS04/14/19

Some time next week I'll be going to a friend of mine who has a later and more
sophisticated IC test card in his PC. Hopefully, I'll be able to sort out the
"multiple" 74 series identified by the Fairy card as well as the "unknowns".
Can somebody please archive this for others to access in later years.
ONE LAST NOTE : Please NOTE that you CANNOT use this card in a IIe. It will
accelerate but you'll get a ddoouubbllee pprriinntt problem. There was a IIe
version of this card. I have the preboot disk for the II Plus accelerator if
anyone needs it as well as the manual that came with the II Plus accelerator.
