ROMs for SA II -------------- The schematics for the SA II call for 300 ns 27512s. If that is what you really want, then that is what I will specify. However, you should know that a 27512 is an NMOS part and we do not stock them and they may be difficult to get. (CMOS has generally taken over.) Note also that we do not stock 300 ns EPROMs or OTPs. Tell me which part you want to use. EPROMs ------ Type Atari PN Speed Type Cost # in inventory --------- ---------- ------ ---- ----- -------------- 27C512-300 137448-300 300 ns CMOS $ none 0 27C512-250 137448-250 250 ns CMOS $ 4.50 52,238 27C512-200 137448-200 200 ns CMOS $ 5.70 17,487 27512-300 137444-300 300 ns NMOS $ 6.75 0 27512-250 137444-250 250 ns NMOS $ 6.50 0 27512-200 137444-200 200 ns NMOS $ 7.90 0 OTPs ----- 27C512-300 137454-300 300 ns CMOS $ 3.80 0 27C512-250 137454-250 250 ns CMOS $ 5.10 46,559. 27C512-200 137454-200 200 ns CMOS $ 5.35 23,511.

Here are the part numbers for Stun Runner SA II: The schematics calls for 27512-300 but since we don't have any, Byron has approved the use of 27C512-250 . 136070-1123 10C 27C512, 250 ns 136070-1124 1C/D 27C512, 250 ns 136070-1125 1D/E 27C512, 250 ns 136070-1126 1E/F 27C512, 250 ns 136070-1127 1F/H 27C512, 250 ns Jed

I have looked at the SA II TOPP.LIS and although you have used the programmed part numbers I gave you, you have listed the parts as 300 ns even though I asked you to use 250 ns. Please explain. (Did someone tell you to do this?) Jed

JED, BYRON SHEPPARD CHANGED THE PARTS TO 300N. HE WAS TOLD BY HIS SUPERIORS TO CALL OUT 300N BUT OK 250N WHEN PURCHASING ASKED TO SUBSTITUTE.THIS WAS A LAST MINUTE CHANGE BEFORE RELEASING THE PARTS LIST.I AM SORRY YOU WERE NOT KEPT INFORMED. JOE
