In reviewing the MultiSync Hardware costing a couple of areas appear low, and I would expect them to be issues for contnetion at the initiation meeting. I would recommend revising them. 1) 27512 OTP EPROMS: I checked with Rod Petersen, and we have never bought 27512 OTP's for less than $4.80. We have a supply at that price through September. After that, the price goes to $5.30. I suggest using $5.30. I also suggest costing the elctronic hardware WITHOUT EPROMS since the price and quantity can vary so much. I suggest that the EPROM Cost should be a separate item on the final assembly cost estimate placed right under the elctronics cost. 2) SRAMs: As of today, on Vindicators which is in production, 8k x 8 SRAMS vary in cost from $5 for 100 nS to $8 for 55 nS. Gary has a qoute on Toobin (production in June) for 1k x 4, 25 nS SRAMs of $7.65. I have no information to forcast where SRAM cost are going, but prudence suggests using a cost around $5-6. 3) Raw PCB cost: The lowest price we have for a recent PCB purchase (Blasteroids) was $.34 per sq. inch. this was a small PCB (100 sq. in.) and they made them "2-up" to reduce cost. A recent quote on the larger Toobin PCB (200 sq. in.) came to $.38 per sq. in. I suggest revising Mult-sync PCB costs accordingly.
